ABSTRACTSpecies lists are sources of information for studies of both conservation and macroecology. It is, however, importantto differentiate between relatively complete lists and extremely incomplete ones. The aim of this study was to evaluatehow sampling effort typically used in inventories affects the number of bat species captured in areas of Atlantic Forestin southeastern Brazil. We also evaluated if the number of sampled sites, size of the sampled area, and sampling effort(net hours) affect species richness. We used previously reported data from studies in Rio de Janeiro, Sao Paulo, andMinas Gerais States, and our own data collected during 1989 and 2001. Nonlinear models fit well the data for Riode Janeiro and Minas Gerais States and all states together, but not for Sao Paulo State. Genera richness showed asimilar pattern to that of species richness. The model used to explain the relationship between species richness andsize of the study area, number of sites, and sampling effort sampled was significant. The number of sites sampledexplained a significant part of the variation observed; however, other variables contributed nothing to the model,suggesting that capturing beta diversity is the most important aspect of biodiversity surveys for bats, and that increasingnet hours at a given location is much more inefficient than distributing net hours across locations. We suggest 1000captures as the minimum necessary when sampling with mist nets to capture the majority of phyllostomid species fora given site (alpha diversity). In addition, we suggest that shifting the position of the mist nets between nights willincrease the probability of capturing more species.
RESUMOAs listas de especies sao fontes de informacoes para estudos, tanto de conservacao quanto de macroecologia. Entretanto,e importante diferenciar entre listas relativamente completas daquelas seriamente incompletas. O objetivo deste estudofoi avaliar como o esforco amostral mınimo tipicamente usado em inventarios afeta o numero de especies de morcegoscapturados em areas de Mata Atlantica do sudeste do Brasil. Nos tambem avaliamos se o numero de pontos amostrados,o tamanho da area amostrada e o esforco de captura (hora-rede) afetam a riqueza de especies. Nos usamos dadosdisponıveis de estudos desenvolvidos nos estados do Rio de Janeiro, Sao Paulo e Minas Gerais, e os nossos propriosdados coletados de 1989 a 2001. Modelos nao-lineares se ajustaram para os estados do Rio de Janeiro e Minas Geraise todos os estados juntos, mas nao para o Estado de Sao Paulo. A riqueza de generos mostrou o mesmo padrao dariqueza de especies. O modelo usado para explicar a relacao entre riqueza de especies e tamanho da area de estudo,numero de pontos amostrados e esforco amostral foi significativo. O numero de pontos amostrados explicou umaparte significante da variacao observada. Contudo, as outras variaveis nao contribuıram para o modelo, sugerindo quecapturar a diversidade Beta e o aspecto mais importante de inventarios de biodiversidade para morcegos, e que oaumento de horas-rede numa dada localidade e muito mais ineficiente do que distribuir horas-rede entre localidades.Nos sugerimos 1000 capturas como o mınimo necessario para amostrar, com redes de neblina, a maioria das especiesde filostomıdeos de uma dada area (diversidade Alfa). Adicionalmente, sugerimos que mudando a posicao das redesentre noites aumentara a probabilidade de capturar um maior numero de especies.

Minimum Bat Sampling Effort in Atlantic Forest 279
CURRENT EFFORTS IN CONSERVATION ATTEMPT TO
IDENTIFY AREAS with high species richness and highlevels of endemism (Caldecott et al. 1996, Myerset al. 2000). Species lists are sources of basic infor-mation for such efforts (Remsen 1994, Blackburn& Gaston 1998); however, species lists available inthe literature have been obtained by different re-searchers, in different contexts, with distinct aims,and using different techniques (Gaston 1996).These differences can result in biases in describedpatterns of species richness at both local and re-gional scales (Remsen 1994). As a result, it is im-portant to differentiate between relatively completelists and extremely incomplete ones (Silva & Me-dellın 2001).
The mammal fauna of the Atlantic Forest is,proportionally by area, the richest (ca 246 spp.) ofall Brazilian biomes (Fonseca et al. 1999, Costa etal. 2000). The species richness of the bat fauna isalso high (96 spp. or 71% of the species that occurin Brazil), surpassed only by that of the AmazonForest (124 spp.; Marinho-Filho & Sazima 2000).The Atlantic Forest, however, is richer in bat spe-cies than Brazilian Amazonia if one considers thearea of each biome (Fonseca et al. 1999). The levelof bat species endemism is relatively low for bothbiomes (5.2% in Atlantic Forest and 11.1% in Am-azon Forest; Marinho-Filho & Sazima 2000).
Many inventories of bat fauna have been car-ried out in southeastern Brazil, mostly in Sao Pauloand Rio de Janeiro States, where most of the batresearchers in the country reside (Pedro 1998). Inthe Atlantic Forest of southeastern Brazil, at least19 localities have been surveyed (Esberard 1999).These inventories have been conducted in areaswith different degrees of human impact, from ur-ban parks and sites in various successional stages topristine forest sites.
For all of these inventories, bats were sampledusing mist nets. This is the most commonly usedmethod for bat sampling (Kunz & Kurta 1988)and seems to be the most useful for non-insectivorebat taxa (Voss & Emmons 1996), especiallyphyllostomids and other bats that forage in the un-derstory (Kalko 1998). Some studies (Fenton et al.1992, Wilson et al. 1996) have shown that speciesof the family Phyllostomidae, mainly from the sub-family Phyllostominae, are indicators of habitat dis-turbance, since this family is considerably specioseand its species display a high variety of food habits(Fenton et al. 1992, Schulze et al. 2000). Membersof the families Noctilionidae, Emballonuridae, Na-talidae, Thyropteridae, Vespertilionidae, and Mo-lossidae tend to be less frequently sampled. Meth-
ods such as harp traps or acoustical methods (e.g.,Anabat) rarely have been used for inventories insoutheastern Brazil.
The goal of this study was to evaluate howsampling effort typically used in inventories affectsthe number of bat species sampled in Atlantic For-est of southeastern Brazil. Furthermore, in areaswith greater sampling effort, we were able to de-termine if factors such as number of sampled sites,the size of the area, and sampling effort (net hours)affect species richness.
MATERIALS AND METHODS
To evaluate if the total number of captures em-ployed in different studies was sufficient to inven-tory the species richness of bats in the sampledlocalities, we used both data from the literature andthose collected by ourselves during 1989 and 2001(Table 1). We selected only studies conducted inthe Atlantic Forest of southeastern Brazil (Rio deJaneiro, Sao Paulo, and Minas Gerais States) thatdescribed the total number of captures. Data for59 localities in the Atlantic Forest of southeasternBrazil were analyzed, including 6 localities in Mi-nas Gerais State, 7 in Sao Paulo State, and 46 inRio de Janeiro State (Fig. 1; global positioning sys-tem locations can be obtained from the authors).The total number of captures refers to the totalnumber of bats recorded. Since many authors didnot mark the captured animals, we included recap-tures in the total number of captures. All studiesused mist nets and bats were either capturedthroughout the entire night or only during part ofit.
Sao Paulo and Rio de Janeiro States have atleast 63 and 65 bat species, respectively (Pedro1998, Bergallo et al. 2000; C. Esberard, pers. obs.).Minas Gerais State does not have an updated listof bat species. The fourth state that integrates theso-called Southeastern Region of Brazil, EspıritoSanto, has so far only one locality sampled for bats(Peracchi & Albuquerque 1993). We could not usethis study because the authors did not describe thetotal sampling effort and the number of captures.
The effect of sampling on species richness wastested with linear and nonlinear models for MinasGerais, Sao Paulo, and Rio de Janeiro States, andfor all states pooled. We repeated the analysis usinggenera as indicators of the effect of sampling inspecies lists. In the nonlinear models, the measuresobtained are raw R2 and R2. The raw R2 is theproportion of the variation in y (species richness inthis study) that is explained by the sum of squares

due to regression, whereas R2 is the correlationsquared between the observed values and predictedvalues (Wilkinson 1997). According to this author,some researches object to raw R2 because themeans are not removed. We also estimated theWald confidence interval (95%) for the three pa-rameters of the nonlinear models for species andgenera of all states pooled (Wilkinson 1997).
We also tested for the effect of study area size,number of sampling sites, and sampling effort (to-
tal net hours), using only inventories conducted inRio de Janeiro State that had a minimum samplingeffort of 820 captures (Table 2). The size of thestudy area was recorded as the size of the protectedarea where the study was conducted. The numberof sampling sites was considered as the sites wheremist nets were opened in each locality. Each siterepresented a different habitat (e.g., river, bananaplantation, forest, clearings) and the minimum dis-tance between them was ca 1000 m. Sampling ef-fort (net hours) was considered as the total numberof hours multiplied by the total number of nets.We used total net hours in the multiple regressionto test the consistency of our suggested index ofsampling effort, the number of individual captures.We used Systat 7.0 to analyze the data and plotthe figures (except Fig. 1).
RESULTS
TAXA RICHNESS X TOTAL SAMPLING EFFORT. The to-tal number of captures varied from 16 to 2361records (x 6 SD 5 397.6 6 527.5). The appendixlists the species captured by state.
The proportion of variation in the total of spe-cies explained by the sum of squares due to regres-sion (raw R2) was 0.95, and the correlation squaredbetween the observed values and the predicted val-ues (R2) was 0.70 (Fig. 2a). Estimated speciesnumber stabilized at ca 1000 captures (Fig. 2a).Although the number of species increased with thenumber of captures in Minas Gerais (raw R2 50.99, R2 5 0.89, N 5 6, range 5 45–372 cap-tures), no asymptote was reached (Fig. 2b). For SaoPaulo State, the relationship between total capturesand number of species was not significant (R2 50.43, P 5 0.336, N 5 7, range 5 117–946 cap-tures; Fig. 2c). Because studies in Rio de JaneiroState corresponded to 80 percent of the total sam-pling, the relationship between the number of spe-cies and the total number of captures was similarfor that state (Fig. 2d) to that for all localities to-gether (raw R2 5 0.97, R2 5 0.83, N 5 46, range5 16–2361 captures), with the curve stabilizing atca 1000 captures.
Species richness, based on the entire data set,varied from 5 to 27 (x 5 14.0 6 6.3 spp.). Con-sidering only those localities with a minimum 1000captures, the mean species number was 22.4 (63.6, N 5 7, range 5 18–27 spp.). Considering theWald 95 percent confidence interval, with 1000captures the species number can range from 12 to25 (Fig. 2e).
The number of genera observed varied with the

The mea-sures of the nonlinear models considering all lo-calities were raw R2 5 0.93 and R2 5 0.62, andfor Rio de Janeiro State, raw R2 5 0.93 and R2 50.70. Considering all states, the mean number ofgenera across all localities was 10.4 6 5.1 (varyingfrom 3 to 20), but was 16.4 (6 4.4, N 5 7, range
5 8–20 genera) for those localities with a mini-mum 1000 captures. Figure 2f shows the confi-dence intervals for the genera curve, ranging from9 to 19 with 1000 captures.
The total number of species expected for MinasGerais State is slightly higher (23.2) than that ex-pected for Rio de Janeiro State (22.8) at a samplingeffort of 1500 captures (Fig. 3). The nonlinear

model for Minas Gerais State suggests a faster in-crease in the number of bat species with samplingeffort and an asymptote at a lower number of cap-tures than that observed in Rio de Janeiro State(Fig. 3). Based on curves for 1500 captures, 98percent of the species would be captured in local-ities of Minas Gerais after only 750 captures, while1100 captures would be necessary to capture 98percent of the species of the typical Rio de JaneiroState.
FACTORS AFFECTING SPECIES RICHNESS. The linearregression of species richness in Rio de Janeiro Stateon size of the study area, number of sites sampled,and sampling effort (net hours) was positive andsignificant (R2 5 0.904, F 5 15.652, P 5 0.006,N 5 9). Only the partial regression coefficient forthe number of sites sampled was significant (P 50.020; Fig. 4; Table 2).
DISCUSSION
Southeastern Brazil is the country’s best studied re-gion for bats. Even in this region, however, ourresults suggest that greater sampling is needed toattain reliable estimates of species richness. Addi-tionally, although montane areas are very commonin this region, they are very under-sampled.
Because insectivorous bats are usually able todetect mist nets, only the hematophagous, frugiv-orous, nectarivorous, and gleaner species tend to beconsistently sampled. Those species belong to thefamily Phyllostomidae (87 spp. in southeasternBrazil; Pedro 1998) and represent ca 90 percent ofthe captures in the Neotropics (Kalko et al. 1996).But all species for a given region are never sampledfor the following reasons: (1) insufficient samplingeffort, with a limited number of sample sites; (2)species rarity, due to habitat specificity and/or re-duced or small population size; (3) dietary speci-ficity, sampling affected by proximity to foodsources (Tuttle 1974, 1976); (4) greater capacity ofsome phyllostomid species to detect mist nets (Kal-ko et al. 1996); (5) flight areas high above the net(Handley 1967; Bonaccorso 1979; Francis 1990,1994; Bernard 1997); and (6) home range of batsbeing restricted to the neighborhood of the dailyrefuge (Kalko et al. 1996).
This study demonstrated that a high numberof captures are necessary to obtain an accurate es-timate of the bat species richness for a given area.Richness of genera followed the pattern observedfor species richness. Grelle (2002) observed that thespatial distribution of the genera belonging to Mar-supialia, Chiroptera, Rodentia, and Primates wasrepresentative of the species spatial distribution.Hence, genera richness seems to be a good indi-

cator of species richness, since species of the samegenera cannot have a similar capture efficiency.
The minimum sampling effort of 1000 cap-tures appears to be a consistent index to capturethe majority of phyllostomid species in a givenarea. According to Morrison (1978, 1980), moresampling nights can produce a greater number ofspecies than more hours of nocturnal sampling, be-cause a great number of bat species are active main-ly after sunset. Nevertheless, some species may beactive late in the evening; thus, it is important to
do the sampling all night long when possible (Kunz1982).
The number of sites showed a strong relation-ship with the number of species recorded. De-pending on the life history of the bat species, somesites will be better than others. Furthermore, it isknown that bats learn the position of the mist nets,diminishing the capture success during subsequentnights (Kunz & Kurta 1988). In addition, manyspecies of bats restrict their activities to the neigh-borhood of the refuge (Kalko et al. 1996) and thevariation in the sample sites can increase the prob-ability of sampling such species. Capturing be-tween-site variability (beta diversity) seems to bemore important than determining the full speciescomplement that may occasionally fly over one site(alpha diversity).
Even the amount of 1000 captures and shiftingthe net position may not be enough to representthe overall richness of species and genera in a givenarea. More than 170 nights and 7000 captures weremade in Tijuca National Park, and species are stillbeing added to the inventory (C. Esberard, pers.obs.). This is also the case at Poco das Antas Bio-logical Reserve, in which a total of 2596 captureswere recorded (Mello 2002). Continuous and largesample efforts have already been suggested by Kal-ko et al. (1996). After 43 years of sampling withmist nets and more than 50,000 captures on BarroColorado Island, Panama, 61 species have been re-corded, with 5 more species added using acousticmethods.
Studies using different sample methodologiesare necessary to obtain complete inventories of batfaunas, which could show if the richness of phyllos-tomid species and genera reflects the total bat spe-cies richness of the area. If so, the phyllostomidrichness or the richness of species captured in mistnets could be used as an index of the total batspecies richness.
