“…Although conservation prioritization must consider important socioeconomical factors in addition to observed or predicted extinction risk (Possingham et al 2002;Miller et al 2006), the latter is a key input variable for priority setting. Therefore, identifying species of conservation concern among data deficient groupers is considered high priority research for their management (Sadovy de Mitcheson et al 2013).…”

Groupers are highly susceptible to human-induced impacts, making them one of the most threatened fish families globally. Extinction risk assessments are important in endangered threatened species management, however the most comprehensive-the International Union for Conservation of Nature (IUCN) Red List-cannot classify approximately one-third of grouper species due to data deficiency. We used an ordinal analytical approach to model relationships between species-level traits and extinction risk categories. We found that larger species and those with shallower maximum depths and smaller geographic ranges had higher extinction risk. Using our best fitting model, we classified data deficient grouper species into IUCN's extinction risk categories based on traits. Most of these species were predicted to be of least concern. However, 12% were predicted to be endangered or vulnerable, suggesting that they may be of conservation interest. Importantly, we provide a quantitative method for overcoming data gaps that can be applied to conservation of other species.

“…Species lists (Wachlevski and Rocha 2010;Telles et al 2012;Affonso et al 2014;AlmeidaGomes et al 2014;Crivellari et al 2014) typically constitute an essential first step for the monitoring of the fauna of specific habitats and the assessment of the status of species and their populations, which can be used to guide conservation decision-making (Pimenta et al 2005), especially considering that most strategies are based on local species richness (Rocha et al 2003) and on the extinction risk of different species (Miller et al 2006).…”

Abstract:We provide an updated checklist of the anurans of the Salto Morato Nature Reserve (SMNR), Paraná, southern Brazil, including information on species endemism, conservation status, habitat use, and reproductive modes. We sampled the study area between February 2013 and July 2015, using Visual Encounter Surveys, totaling 700 hours of sampling effort. We supplement our primary data with secondary data (published papers and voucher specimens), and through these, we found a total of 54 anuran species representing 23 genera and 10 families. All the frogs recorded are endemic to the Atlantic Forest. Although no species has been listed as Endangered on the Red Lists of Paraná state, Brazil, and the IUCN, five are classified as Data Deficient. Most of the species recorded were arboreal (55.5%), a third were terrestrial (33.3%), and the remainders were rheophilic (11.1%). We identified 18 different reproductive modes, with types 1 (lay eggs in lentic water where the tadpoles develop) and 23 (direct development of terrestrial eggs) being the most common. Our findings indicate that the SMNR currently has the greatest diversity of anuran species and reproductive modes of any area in southern Brazil.

“…As the regional lists are not updated regularly, they tend to provide outdated assessments of conservation status. This situation may reduce the effectiveness of these lists as guidelines for conservation practices, given that most measures are currently based on the evaluation of the extinction risk of the species (Miller et al 2006). It is important to note that the regional lists are important conservation tools, given that most measures are implemented on a local scale (Possingham et al 2002).…”

Anuran amphibians in state of Paraná, southern Brazil

The state of Paraná, located in southern Brazil, was originally covered almost entirely by the Atlantic Forest biome, with some areas of Cerrado savanna. In the present day, little of this natural vegetation remains, mostly remnants of Atlantic Forest located in the coastal zone. While some data are available on the anurans of the state of Paraná, no complete list has yet been published, which may hamper the understanding of its potential anuran diversity and limit the development of adequate conservation measures. To rectify this situation, we elaborated a list of the anuran species that occur in state of Paraná, based on records obtained from published sources. We recorded a total of 137 anuran species, distributed in 13 families. Nineteen of these species are endemic to the state of Paraná and five are included in the red lists of the state of Paraná, Brazil and/or the IUCN. Two anuran species were categorized as Near Threatened by the IUCN and 27 species were listed as Data Deficient in one or more lists. According to IUCN 49.6% of the anuran species recorded had their population trends stable, 19% in declined, only 1.4% is increased and 20.4% had your population trends unknown. We also recorded the occurrence in Paraná of the exotic invader anuran Lithobates catesbeianus. We consider our list of species to be a relatively reliable estimate of the anuran diversity of the Brazilian state of Paraná, although new species records are expected, mainly because there are many regions that have not yet been sampled. Keywords: Atlantic Forest, checklist, Cerrado, inventory, species richness. Anfíbios anuros do estado do Paraná, sul do BrasilResumo: O estado do Paraná, localizado no sul do Brasil, originalmente possuía praticamente toda sua área coberta pelo bioma Mata Atlântica com algumas porções do bioma Cerrado. Atualmente, pouco resta das formações destes biomas, sendo a maior parte remanescentes florestais de Mata Atlântica, localizados na região costeira do Estado. Apesar de haver estudos sobre anuros no estado do Paraná, até então nenhum deles proveu uma lista dos anuros com ocorrência no Estado, o que pode dificultar o conhecimento sobre a potencial diversidade de anuros e restringir medidas de conservação. A partir dessa lacuna, elaboramos uma lista das espécies de anuros com registro para o Paraná, a partir de dados de estudos publicados. Registramos um total de 137 espécies de anuros, pertencentes a 13 famílias. Dentre estas, 19 espécies de anuros são endêmicas do estado do Paraná e cinco encontram-se relacionadas sob algum grau de ameaça de extinção na lista vermelha do estado do Paraná, do Brasil e/ou da lista global da IUCN. Duas espécies de anuros foram categorizadas como Quase Ameaçada pela IUCN e 27 espécies foram listadas como Dados Insuficientes nestas listas. De acordo com a IUCN, 49,6% das espécies de anuros registradas apresentaram tendências populacionais estáveis, 19% diminuíram, apenas 1,4% aumentaram e 20,4% apresentaram tendências de sua populações desconhecidas.
