Diversity and conservation of fishes from karstic areas of the Jandaíra Formation in the Brazilian semiarid

“…1), located mainly in Felipe Guerra and Governador Dix-Sept Rosado municipalities, was identified as of very high biological importance and as a priority area for the Caatinga conservation (MMA, 2018). In this area, 40 species of woody trees and more than 200 species of amphibians, reptiles, birds and mammals were recorded (Marinho et al, 2018;Vargas-Mena et al, 2018;Sagot-Martin et al, 2020;Marques et al, 2021). In addition, the record of more than 700 caves in this region and the higher concentration of troglobitic invertebrate species in the RN complement this scenario of extreme biological relevance (CANIE/CECAV 2022, Bento et al, 2021).…”

An annotated avian inventory of the Brazilian state of Alagoas, one of the world’s most threatened avifauna

“…The avifauna of the state of Alagoas is relatively well known compared with that of other states in northeastern Brazil (e.g., Sagot-Martin et al, 2020). Marcgrave's pioneering contribution along with that of some ornithologists who conducted important ornithological surveys in the state (Pinto, 1952(Pinto, , 1954Pinto & Camargo, 1961;Teixeira et al, 1986Teixeira et al, , 1987Teixeira et al, , 1988Teixeira et al, , 1989Teixeira et al, , 1993Roda, 2003;Silveira et al, 2003a; and, more recently, records produced by birdwatchers (approximately 39 spe-cies listed herein were first recorded for the state by birdwatchers who archived their records on WikiAves), have culminated in a list of 520 bird species recorded in the state, of which 503 have at least one record with associated documentary evidence.…”

“…A single undocumented record in Alagoas (Silveira et al, 2003a) is likely a misidentification of White-winged Swallow Tachycineta albiventer. Although T. leucorrhoa is known to occur in extreme northeastern Brazil (Sagot-Martin et al, 2020), and thus its occurrence in the state would not be unexpected, the putative Alagoas record was near a large water reservoir, typical habitat of the regionally much commoner T. albiventer, which is absent in Silveira et al's (2003a) list.…”

“…Despite the lack of documentary evidence, we consider this record to be valid because there are documented records less than 80 km away in the neighboring state of Sergipe (e.g., WA 3982455; L.D. Barros), and others north of the São Francisco River in the states of Paraíba (WA 1281651; M. Holderbaum) and Rio Grande do Norte (Sagot-Martin et al, 2020), suggesting that this species' occurrence in the region is not unlikely.…”

“…Seemingly uncommon and local in the PCE (Roda & Pereira, 2006;Sagot-Martin et al, 2020). Reference works, likely based only on records from the state of Maranhão and unaware of the species' occurrence in the PCE, usually assign the populations throughout northeastern Brazil to the whitish-bellied Amazonian form S. v. superciliaris (König & Weick, 2008;Holt et al, 2020).…”
