“…The increase in studies of lizards has been expanding the natural history and geographical distribution of many species of the Caatinga region (Delfim, 2012;Rodrigues et al, 2013;Cavalcanti et al, 2014;Sales et al, 2015). However, despite new specimens collected and new occurrence records, the relative rarity and restricted occurrence sites of C. carvalhoi was corroborated (Rodrigues, 2003;Delfim, 2012).…”

“…Thus, geographical distribution is an important criterion for assessing the risk of extinction and species conservation status (IUCN, 2012). However, the limited data from species occurrence records make it difficult to investigate geographical distribution and conservation aspects (Araújo and Williams, 2000;Guisan and Thuiller, 2005;Winck et al, 2014;Sales et al, 2015).…”

“…Recent data has shown the occurrence of diverse and endemic lizards in the Caatinga domain (Rodrigues 2003;Cavalcanti et al, 2014;Delfim, 2012;Ribeiro et al, 2012;Garda et al, 2013). However, the geographical distribution, natural history and population information for these species are unsatisfactory, making conservation Caatinga lizards difficult (Rodrigues, 2003;Cavalcanti et al, 2014;Delfim, 2012;Sales et al, 2015).…”

Ecological niche modeling has contributed to the investigation of the geographical distribution and conservation of rare or little recorded species. Therefore, we studied the known and potential distributions of Colobosauroides carvalhoi Soares and Caramaschi 1998 and discuss the implications for its conservation. Data were obtained by manual collections made in quarterly samplings in three different regions, considering the regions with occurrence records and surrounding areas. The known distribution was determined by occurrence records and literature data, and potential distribution was estimated with an ecological niche model by the MaxEnt algorithm. Twenty-five specimens were collected exclusively in forest formations of Caatinga and Caatinga-Cerrado. Our data corroborated the relative rarity of C. carvalhoi and reflected the biogeographical history of the group, where it is restricted to forest formations with milder environmental conditions. The occurrence records indicated new records of C. carvalhoi, but the known distribution value is compatible with a restricted distribution. The ecological niche model estimated few areas with environmental suitability for the species and corroborated the restricted and relict distribution patterns. Finally, the known and potential distribution values were compatible with criteria for threatened species. These results suggest a worrisome scenario for C. carvalhoi conservation. However, the limited data about the species population do not allow the proper definition of its conservation status. Therefore, we suggest using potential distribution values with alternative criteria for redefining the conservation status of C. carvalhoi and the development of new studies that support a better assessment of its conservation aspects.

“…This species is distributed throughout most of the Northeast geopolitical region of Brazil, especially in the Caatinga biome, sometimes reaching the coastline (Forzza, 2005). Encholirium spectabile may be considered a key species for local biodiversity due to its associations with several other organisms, mainly due to the shape of their clumps that form large tangles on rocky outcrops, creating a refuge protected by the hard and abundant thorns present on the bromeliad's leaves (Jorge et al, 2014;Jorge, 2015;Sales et al, 2015).…”

AbstractThere have been few studies about the pollinators of bromeliads of the genus Encholirium. Considering this lack of information, this study comes to fill a gap in the literature on the floral visitors and potential pollinators of E. spectabile. In order to perform this study, we observed the inflorescence of this species between 2011 and 2014 (four years of observation), in the semiarid region of Santa Maria municipality (Rio Grande do Norte state, northeastern Brazil). Floral visitors were observed through focal method. The observations were made during the day, starting at 06h a.m. until 06h p.m., and at night from 07h until 11h59 p.m. In about 1,800 hours of observations, 24 species were recorded visiting E. spectabile flowers, including 4 species of moths (Lepidoptera: Sphingidae and Geometridae), 3 species of bees (Hymenoptera: Apidae), 4 species of hummingbirds (Aves: Trochilidae) and 2 species of bats (Chiroptera: Phyllostomidae), among others. Based on these results, we propose that the macambira bromeliads (E. spectabile) should be considered as key elements in the conservation of various taxonomic groups in the semiarid region, through the umbrella species theory as already proposed for other species of Bromeliaceae. Keywords: associated fauna, caatinga biome, macambiras, Encholirium spectabile, biodiversity. ResumoExistem poucos estudos a respeito dos polinizadores de bromélias do gênero Encholirium. Dessa forma, este estudo vem preencher a lacuna na literatura sobre os visitantes florais e potenciais polinizadores de E. spectabile. Para sua realização, observamos a inflorescência dessa espécie no período de 2011 a 2014 (quatro anos de observações), na região semiárida, no município de Santa Maria, Rio Grande do Norte, Brasil. Os visitantes florais foram registrados por meio do método focal. As observações foram conduzidas durante o dia, começando às 06h da manhã e seguindo até às 18h e, à noite, das 19h às 23h59min. Em cerca de 1.800 horas de observação, 24 espécies foram registradas visitando a inflorescência de E. spectabile, incluindo 4 espécies de mariposas (Lepidoptera: Sphingidae e Geometridae), 3 espécies de abelhas (Hymenoptera: Apidae), 4 espécies de beija-flores (Aves: Trochilidae) e 2 espécies de morcegos (Chiroptera: Phyllostomidae), entre outros. Com base nesses resultados, e subsidiados pela teoria das espécies guarda-chuva, sugerimos que as bromélias macambiras (E. spectabile) sejam consideradas como elementos chave na conservação de vários grupos taxonômicos de região semiárida.Palavras-chave: fauna associada, bioma caatinga, macambiras, Encholirium spectabile, biodiversidade.

The gymnophthalmid genus Anotosaura currently comprises two named species: Anotosaura collaris Amaral, 1933 and Anotosaura vanzolinia Dixon, 1974. Anotosaura vanzolinia (Figure 1) was described as A. collaris vanzolinia by Dixon (1974) based on specimens from the municipality of Agrestina, in the Agreste region of the state of Pernambuco, Brazil. Two years later, Vanzolini (1976a) elevated A. c. vanzolinia to specific rank. It is an insectivorous species that feeds mainly on ants and termites, as well as other arthropods of the edaphic microfauna (Oliveira and Pessanha, 2013). It has a cryptic and semifossorial habit, and it inhabits microhabitats with warmer temperatures, abundant leaf litter, and no incidence of direct sunlight (Delfim and Freire, 2007; Freire et al., 2009). The species has a disjunct and relictual distribution within the Caatinga Domain, where it is found only in mesic areas (Rodrigues, 1986, 2003). The geographical distribution of the species has been based on 12 different locations reported in the literature for the states of Bahia,
