Abstract

The southeast region of the Gulf of Mexico is considered to be biologically important because it is a connection and transition zone between the Caribbean and the Gulf of Mexico harboring great marine biodiversity Nevertheless benthic amphipods have been poorly studied in the Mexican southeast sector of the Gulf of Mexico with few studies listing species The aim of this study is to provide an update checklist of species for the Mexican southeast sector (based on literature review and records from the present study) as well as a brief zoogeographical analysis for the Gulf of Mexico amphipod fauna putting them in context with the fauna on the tropical western Atlantic Fifty-five species were listed for the Mexican southeast sector 36 of them showed a geographical extension to the Yucatan continental shelf representing 23 new records for the Mexican southeast sector nine for the southeast region and four for the Gulf of Mexico Based on the zoogeographical analysis there is support of the application of Carolinian and Caribbean zoogeographic provinces to amphipods in the Gulf of Mexico

Introduction

Benthic amphipods inhabit a variety of substrata including hard and soft bottoms submerged aquatic vegetation and other benthic organisms (eg sponges corals anemones tunicates) The high morphological diversity of amphipods dwelling on sandy sediments suggests a great adaptive radiation (Bousfield 1970) Benthic amphipods obtain a great part of their food from the sediment or water column displaying major feeding modes such as detritivory filter-feeding herbivory predatory scavenging and sand-cleaning (Bousfield 1973 Biernbaum 1979) This ecological diversity has conferred them the ability to colonize all marine habitats and a broad interval of depth from intertidal to abyssal zone (Thomas 1993 Escobar-Briones amp Winfield 2003 LeCroy et al 2009) Biologically the reproductive strategy in amphipods is to brood their eggs in a marsupium releasing them as miniature versions of adults (direct development) and in some cases providing parental care (Thiel 1999) Thereby species show a trade-off condition to achieve reproductive success (Sainte-Marie 1991 William et al 2001)

Amphipods are important for bioturbation because they promote the interchange of gases (mainly oxygen and nitrogen) and contribute high rates of secondary production for energy flow to higher trophic levels (Marques amp Bellan-Santini 1993 Duffy amp Hay 2000 Soliman amp Rowe 2008) These ecological and biological traits have positioned amphipods as one key link between the sediment and the water column

Despite their importance there are many marine regions where amphipods are often ignored leaving a gap of information which provides an erroneous assessment of the regional biodiversity One approximation to solve this crisis is to make checklists of species based on reliable identification or taxonomic revision This is the first step in establishing a framework of how many and which species are in which habitats (alpha beta and gamma diversity) According to Hendrickx and Harvey (1999) a checklist of species provides information about the complexity of the biological communities and the live resources available helping to recognize and to delimit the protected areas and to identify potential anthropogenic impacts

Regarding amphipod fauna in the Gulf of Mexico (GM) the study of gammarideans sensu lato has been constant and productive It can be noted in the number of species for instance of the 418 species (excluding anchialine freshwater and troglobitic) documented in the tropical western Atlantic (TWA) (Ortiz et al 2007) 131 of them (31) have been reported in the GM (LeCroy et al 2009) In addition based on the composition and abundance of benthic macrofauna amphipods in the northeastern region of the GM represent the second most important taxa just below the polychaetes (Brooks et al 2006)

However excluding the relatively well-known amphipod fauna of the Florida Keys and Northwestern Cuba this taxon has been poorly studied in the southeast region of the GM For instance to date only two studies recording benthic amphipods in the Mexican southeast sector have been published (Ortiz 1979 Oliva-Rivera amp Jimeacutenez-Cueto 1997) becoming the sector with the lowest number of species in the GM (Escobar-Briones amp Winfield 2003) Likewise only two studies describing the distribution and abundance patterns of species have been published (Paz-Riacuteos 2008 Rodriacuteguez-Pliego et al 2011) More recently in adjacent waters toward the southeastern region Escobar-Briones and Jimeacutenez-Guadarrama (2010) described the distribution and abundance patterns of peracarids (including amphipods) on the Campeche Bank although their analysis was at the family level Simotildees et al (2010) provided a list of crustaceans for the coast of Yucatan State including amphipods but this list is partially based on unconfirmed material from biological collections

Therefore for updating and providing new information on the amphipod fauna in southeastern GM the aims of this study are 1) to provide an annotated checklist of species for the Mexican southeast sector of the GM 2) to report geographical extensions for those species and 3) to provide a brief analysis of zoogeographical affinity of the GM amphipod fauna inside the TWA amphipod fauna

Methods

Study area Sampling was carried out in the Yucatan continental shelf at 20ndash40 m depth in the southeast region of the GM (Fig 1) The Yucatan continental shelf includes the submerged portion of a shallow limestone plateau which is expanded 220 km toward the northeast (Logan et al 1969) These same authors also state that the inner continental shelf has a gentle slope from south to north and is bounded on the west north and east by a precipitous continental slope that plunges from the submerged plateau margin to the abyssal depths of the GM and Caribbean The water column on the continental shelf forms part of a superficial layer (100ndash150 m) which is well-known as a layer of mixture (Pica amp Pineda 1991) The dominant current comes from a branch of the North Atlantic current which penetrates through the Yucatan strait to the GM (DiMarco et al 2005) Substratum is mainly composed of carbonated sand of autochthonous origin with more than 75 of carbonates which reflects the presence of coral reefs on the shelf (Logan et al 1969 Balsam amp Beeson 2003)

Sample collection and processing Benthic samples were collected on board the RV Onjuko during an oceanographic cruise ldquoYucatan 2004-Ardquo (April 5ndash16 2004) carried out by the Department of Oceanography of the Mexican Navy Eighteen stations were positioned (Fig 1A Table 1) and each station was sampled in duplicate using a

Petite Ponar grab (023 m-2) excepting the stations 2 14 and 18 due to adverse meteorological conditionsBoth sediment and fauna were analyzed Sediment texture was analyzed following Bale and Kenny (2005) and is

characterized in Table 1 Faunal samples were anaesthetised with MgCl2 and then fixed with 10 formaldehyde solution buffered with seawater before storage The samples were washed through 500 μm size mesh and transferred to 70 ethanol Species were sorted and identified to the lower taxonomical level All species are deposited in the Coleccioacuten de Invertebrados Bentoacutenicos de Yucataacuten (CYMX) Cinvestav each species herein reported has a catalog number for the collection (collected and identified by CE Paz-Riacuteos) The classification of Gammaridea is based on Martin and Davis (2001) The classification of Corophiidea is based on Myers and Lowry (2003) members of family Caprellidae and Cyamidae were excluded

Data analysis An annotated checklist of amphipods on the Mexican southeast sector is provided It constitutes a compilation based on literature and records from identified species in the present study doubtful records and personal communication were excluded The checklist includes material examined (if it is the case) distribution habitat and remarks (if necessary)

TABLE 1 Summary information for sampling stations on the northern Yucatan continental shelf southeastern Gulf of Mexico The sampling stations 12 14 and 18 were not collected due to adverse meteorological conditions

From identified species the most abundant and widely distributed species were determined by the absolute abundance (Ind) and relative frequency () To record the geographic extension of species three nested spatial scales were established (Fig 1B) 1) Mexican southeast sector 2) southeast region and 3) GM

To explore the zoogeographical affinity of the GM fauna with the TWA fauna a hierarchical cluster analysis was applied to one species composition matrix of presenceabsence A matrix of species (excluding anchialine freshwater and troglobitic) for the TWA fauna was derived from compilation by Ortiz et al (2007) for six regions Bahamas Barbados Bermuda Caribbean Florida and GM Likewise a matrix of species for the GM fauna was derived from compilation by LeCroy et al (2009) for four regions Northeast Southeast Southwest and Northwest Thus a total of 418 and 232 species were listed for the TWA and the GM respectively After that another matrix was generated from the two above compilations to carry out the analysis to avoid redundant information and ambiguous interpretations in analysis of those regions proposed by Ortiz et al (2007) the Florida region was excluded and interchanged by the four regions of the GM employed by LeCroy et al (2009) Thus this last matrix included 381 shared species among eight regions (Appendix 1) The Sorensen coefficient as similarity index and the average linkage clustering were used to do the hierarchical cluster analysis due to the differences in sample size and sampling effort at the different compilations The statistical software used for analysis was PRIMER v6 (Clarke amp Gorley 2006)

Fauna in the cluster with related regions displayed a gradual affinity southward in geographical distribution from the GM to the Caribbean Northern regions (NE and NW) established the highest similarity (57) with the SW region also related (49) while the SE region and Caribbean were also highly related (50) Zoogeographically the similarity among regions resembles the two major provinces in the TWA Carolinian province and Caribbean province Northern regions corresponded to fauna from the Carolinian province the SW region corresponded to turnover fauna from the Carolinian province to the Caribbean province and the SE region and Caribbean corresponded to fauna from the Caribbean province

Discussion

Species richness The study of amphipods in the GM is conducted by three countries Cuba Mexico and USA The most updated compilation has listed the greatest number of species for the southeast region (Fig 3) this region harbors 66 of the amphipod diversity in the GM Of the countries mentioned earlier Cuba and USA have contributed significantly with descriptions of new species and records Thomas (1993) listed 52 species from the Florida Keys alone pointing out that ldquothese species represent approximately one-third of the total number of amphipod species found in the areardquo On the other hand Ortiz and Lalana (2010) recently listed 99 species from the Cuban Gulf

In the Mexican Gulf amphipods from the southwest sector have been more heavily studied than those in the southeast sector This is reflected in the great number of species (66) recognized in the former sector Studies carried out in the southwest sector include those that focus on ecological roles (Corona et al 2000 Winfield et al2007b) checklists of species (Chaacutezaro-Olvera et al 2002 Winfield et al 2006 2007a Winfield amp Ortiz 2011) and description of new species (Winfield amp Aacutelvarez 2009 Winfield amp Ortiz 2009 2010 2012) The few studies in the southeast sector focus on the ecological distribution (Paz-Riacuteos 2008 Rodriacuteguez-Pliego et al 2011) and checklists of species (Ortiz 1979 Oliva-Rivera amp Jimeacutenez-Cueto 1997 Simotildees et al 2010) Nevertheless due to the great heterogeneity of habitat in the southeast sector (eg beaches coastal lagoons grassbeds reefs) Escobar-Briones and Jimeacutenez-Guadarrama (2010) have suggested that the Campeche Bank on the southeast sector is like a ldquohotspotrdquo of biological diversity for peracarids associated with carbonated bottoms Therefore the reported number of amphipod species here stated will increase with the exploration of new habitats (eg Alacranes Reef) and description of new species (eg Caribboecetes sp)

Four species previously reported in the region were excluded from the checklist of amphipods for the Mexican southeast sector Three of these species [Linguimaera hamigera (Haswell 1879) Eudevenopus cf metagracilis

(Barnard 1964) and Pseudohaustorius carolinensis Bousfield 1965] are listed in Ortiz (1979) and one [Bemlos waipio (Barnard 1970) as Lembos processifer Pirlot 1938] is listed in Oliva-Rivera and Jimeacutenez-Cueto (1997) These species were excluded based on the atypical habitats and distribution ranges reported In addition these species have not been listed for the GM in the most updated checklists of amphipods in the region by LeCroy (2002 2011) Ortiz et al (2007) LeCroy et al (2009) and Ortiz and Lalana (2010)

Another species previously recorded from the GM (see LeCroy et al 2009) but excluded from this checklist was Melita nitida Smith 1873 This species was listed by Oliva-Rivera and Jimeacutenez-Cueto (1997) from the Yalahau Lagoon but based on specimens recently examined from that lagoon M nitida actually represents Melita planaterga Kunkel 1910

Zoogeographic comments The two zoogeographical provinces mostly recognized and widely accepted for the benthic macrofauna of the TWA are the Carolinian and Caribbean provinces (Hedgpeth 1953 Briggs 1974 Barnwell amp Thurman 1984 Kensley amp Schotte 1989 Rabalais et al 1999 Engle amp Summers 2000 Salazar-Vallejo 2000 Raz-Guzman et al 2004 Neigel 2009 Briggs amp Bowen 2012) The Carolinian province is located in the northern GM and has been considered part of the warm-temperate province which includes the northwestern Atlantic coast from Cape Hatteras (North Carolina) to Cape Canaveral (Florida) The Caribbean province is located in the southern GM and has been considered part of the tropical province which extends to the Orinoco Delta River The approximate boundaries between Carolinian and Caribbean provinces in the GM are Cabo Rojo (Veracruz) on the southwestern end and Cape Romano (Florida) on the northeastern end

The hierarchical cluster analysis displayed an overlap between the amphipod fauna and the zoogeographical provinces described above In this case the use of multivariate statistical methods (eg similarity index and average linkage clustering) for establishing zoogeographic provinces was not diminished supporting its efficacy The use of these statistical methods has been widely accepted among researchers who have explored the zoogeographical boundaries in different benthic taxa in the western Atlantic including mysids (Escobar-Briones amp Soto 1991) gastropods (Diaz 1995) macroinfauna (Engle amp Summers 2000) decapods (Wickstec amp Packard 2005) cumaceans (Watling 2009) amphipods echinoderms mollusks polychaetes sponges and stony corals (Miloslavich et al 2010)

Winfield et al (2007c) listed the biotic components dominant for amphipods in the southwestern GM as Endemic (29) Caribbean (25) and Carolinian (25) In this respect although the native species are the major component the shared affinity between Caribbean and Carolinian provinces is also denoting a faunal turnover as is expected in this region Thus the distributional patterns found for southern GM amphipods by Winfield et al(2007c) and the present study suggest a gradual zoogeographical change from the Carolinian-Caribbean province (southwestern region) to the Caribbean province (southeastern region)

Based on the analyzed data matrix in the present study extreme levels of endemism were found in the fauna from regions of the Antillean arc with the highest levels in Barbados (100) and Bermuda (69) characteristic to distant islands and with the lowest level in Bahamas (16) characteristic to a connected archipelago Intermediate levels of endemism but denoting a strong biotic isolation were presented in the fauna from the Caribbean and GM with 47 and 25 respectively Particularly the level of endemism in the GM was estimated at 27 by LeCroy et al (2009) pointing out that this level will diminish with a better knowledge of species distribution In the present study the endemicity in the GM diminished slightly due to the calculation as it had been predicted above it was estimated with 59 endemic species in the present study instead of 62 endemic species in LeCroy et al (2009) With respect to the endemism in the GM regions there is a geographic latitudinal and longitudinal difference likely related to a thermal biogeographic barrier and a sedimentary biogeographic barrier respectively Latitudinally northern regions with a warm-temperate regime (NW= 5 NE= 21) presented higher levels of endemism than southern regions with a tropical regime (SW= 15 SE= 15) Longitudinally eastern regions with carbonated sediments (NE= 21 SE= 15) presented higher levels of endemism than western regions with terrigenous sediments (NW= 5 SW= 15) Furthermore the southwest region showed the lowest level of endemism suitable to a region where presumably come together both Carolinian and Caribbean provinces and there is a high faunal turnover (dissimilarity) from the northwest region to the southwest region (57)

To explain both distributions in the GM provinces we should focus on historical and ecological biogeography The former is concerned with historical meteorologicalgeological events which actually formed the Gulf basin (eg continental drift cycles of glaciations emergence of the Central American Isthmus emergence of the Florida peninsula redirection of the North Equatorial Current northward) which have been treated by Mills (1965) Briggs (1970) McKinney (1977) and Neigel (2009) The latter investigates and describes current environmental traits in the Gulf basin (eg currents depth sediment temperature seabed topography biotic interactions) which have been treated by Hedgpeth (1953) Rabalais et al (1999) Wicksten and Packard (2005) Winfield et al (2006) and Richards et al (2007) In summary amphipod distribution in the GM may have originated via historical events in the tropical Atlantic (Myers amp Lowry 2009) Thus although the influence of the east Pacific (via Central American Isthmus) on the Caribbean (and after on the GM) was high the influence from the Atlantic was stronger (McKinney 1977 Myers amp Lowry 2009) This is currently supported by the amphipod zoogeography of Winfield et al (2007c) where the biotic components with less dominance in the southwestern GM are Euritopic (16) and Oregonian (5) Furthermore of 969 species collectively reported so far in the tropical western Atlantic and tropical eastern Pacific (Ortiz et al 2007 Garciacutea-Madrigal 2008 Foster et al 2009) 59 species display a contemporary amphiamerican distribution representing roughly 6 of the tropical amphipods of America

Page 2: Benthic amphipods (Amphipoda: Gammaridea and Corophiidea) from the Mexican southeast sector of the Gulf of Mexico: checklist, new records and zoogeographic comments

Regarding amphipod fauna in the Gulf of Mexico (GM) the study of gammarideans sensu lato has been constant and productive It can be noted in the number of species for instance of the 418 species (excluding anchialine freshwater and troglobitic) documented in the tropical western Atlantic (TWA) (Ortiz et al 2007) 131 of them (31) have been reported in the GM (LeCroy et al 2009) In addition based on the composition and abundance of benthic macrofauna amphipods in the northeastern region of the GM represent the second most important taxa just below the polychaetes (Brooks et al 2006)

However excluding the relatively well-known amphipod fauna of the Florida Keys and Northwestern Cuba this taxon has been poorly studied in the southeast region of the GM For instance to date only two studies recording benthic amphipods in the Mexican southeast sector have been published (Ortiz 1979 Oliva-Rivera amp Jimeacutenez-Cueto 1997) becoming the sector with the lowest number of species in the GM (Escobar-Briones amp Winfield 2003) Likewise only two studies describing the distribution and abundance patterns of species have been published (Paz-Riacuteos 2008 Rodriacuteguez-Pliego et al 2011) More recently in adjacent waters toward the southeastern region Escobar-Briones and Jimeacutenez-Guadarrama (2010) described the distribution and abundance patterns of peracarids (including amphipods) on the Campeche Bank although their analysis was at the family level Simotildees et al (2010) provided a list of crustaceans for the coast of Yucatan State including amphipods but this list is partially based on unconfirmed material from biological collections

Therefore for updating and providing new information on the amphipod fauna in southeastern GM the aims of this study are 1) to provide an annotated checklist of species for the Mexican southeast sector of the GM 2) to report geographical extensions for those species and 3) to provide a brief analysis of zoogeographical affinity of the GM amphipod fauna inside the TWA amphipod fauna

Methods

Study area Sampling was carried out in the Yucatan continental shelf at 20ndash40 m depth in the southeast region of the GM (Fig 1) The Yucatan continental shelf includes the submerged portion of a shallow limestone plateau which is expanded 220 km toward the northeast (Logan et al 1969) These same authors also state that the inner continental shelf has a gentle slope from south to north and is bounded on the west north and east by a precipitous continental slope that plunges from the submerged plateau margin to the abyssal depths of the GM and Caribbean The water column on the continental shelf forms part of a superficial layer (100ndash150 m) which is well-known as a layer of mixture (Pica amp Pineda 1991) The dominant current comes from a branch of the North Atlantic current which penetrates through the Yucatan strait to the GM (DiMarco et al 2005) Substratum is mainly composed of carbonated sand of autochthonous origin with more than 75 of carbonates which reflects the presence of coral reefs on the shelf (Logan et al 1969 Balsam amp Beeson 2003)

Sample collection and processing Benthic samples were collected on board the RV Onjuko during an oceanographic cruise ldquoYucatan 2004-Ardquo (April 5ndash16 2004) carried out by the Department of Oceanography of the Mexican Navy Eighteen stations were positioned (Fig 1A Table 1) and each station was sampled in duplicate using a

Petite Ponar grab (023 m-2) excepting the stations 2 14 and 18 due to adverse meteorological conditionsBoth sediment and fauna were analyzed Sediment texture was analyzed following Bale and Kenny (2005) and is

characterized in Table 1 Faunal samples were anaesthetised with MgCl2 and then fixed with 10 formaldehyde solution buffered with seawater before storage The samples were washed through 500 μm size mesh and transferred to 70 ethanol Species were sorted and identified to the lower taxonomical level All species are deposited in the Coleccioacuten de Invertebrados Bentoacutenicos de Yucataacuten (CYMX) Cinvestav each species herein reported has a catalog number for the collection (collected and identified by CE Paz-Riacuteos) The classification of Gammaridea is based on Martin and Davis (2001) The classification of Corophiidea is based on Myers and Lowry (2003) members of family Caprellidae and Cyamidae were excluded

Data analysis An annotated checklist of amphipods on the Mexican southeast sector is provided It constitutes a compilation based on literature and records from identified species in the present study doubtful records and personal communication were excluded The checklist includes material examined (if it is the case) distribution habitat and remarks (if necessary)
