“…The mean altitudinal distribution observed for C. l. leucogenys in the present study was similar to that of previous studies (Zyskowski et al 2011), which suggests that the species is less dependent on mountain environments than was previously assumed. The occurrence recorded at 45 m above sea level probably represents an outlier, possibly a vagrant, since the species generally occurs in high-altitude environments (Mee et al 2002).…”

“…Widening the area of C. l. leucogenys occurrence in the city of Boa Nova (Bahia), as highlighted in the present study, has been reported previously (Albano 2013), although the record did not note its biogeographical importance. Similarly, the distribution of C. l. gularis was also widened recently, up to Suriname (Zyskowski et al 2011). This demonstrates that the distribution of the Rufous-brown Solitaire is incompletely understood.…”

Abstract. Vogel HF, Bernardon MM, Zawadzki CH. 2017. Distribution of Cichlopsis leucogenys (Aves: Turdidae) in Brazil and its relation to protected areas. Biodiversitas 18: 1116-1121. The Rufous-brown Solitaire (Cichlopsis leucogenys Cabanis, 1851) is endangered in Brazil, and the demarcation of priority areas is needed for its in situ conservation. Accordingly, we reviewed the distribution of C. leucogenys and assessed its association with protected areas (PAs) by analyzing 70 occurrence records from 1942 to 2014 that were collected from online datasets. Of these records, 38 (54.4%) were from Bahia State, 27 (38.5%) were from Espírito Santo State, and five (7.1%) were from Minas Gerais State, and the Biological Reserve Augusto Ruschi (Espírito Santo State), State Park Serra do Conduru (Bahia State), and Serra do Ouro Environmental Protected Area (Bahia) were identified as key PAs. One record described an observation of the species at 45 m above sea level, which is lower than expected. We verified the potential occurrence of the species in 31 PAs that were located in southern Bahia to the mountains in both Espírito Santo and Minas Gerais. The Ilhéus-Itabuna region should be given special attention during conservation efforts, owing to records of species presence outside PAs, which should also be considered by management plans.

“…Based predominantly on studies from Venezuela (see references in Mayr &Phelps-Jr. 1967 andin Hilty 2003), these montane forests are known to have an avifauna distinct from that of the Amazonian lowlands and with a high degree of endemism. Outside of Venezuela, there have been only a few recent ornithological studies in Guyana (Braun et al 2003, Robbins et al 2007 and Suriname (Zyskowski et al 2011); most montane habitat on the Brazilian side of these countries' borders remains unexplored (but see Borges et al 2014). Thus, the mountains of northern Brazil are likely places to find bird species previously undetected in the country.…”

From 15 January to 06 February 2016, we conducted an expedition to the Serra da Mocidade, a remote and previously unexplored mountain range in extreme northern Amazonian Brazil. There we encountered three bird species never before documented in Brazilian territory: Grallaria guatimalensis (Grallariidae) was photographed, audio recorded, video recorded and a single specimen collected; Catharus aurantiirostris (Turdidae) was similarly documented and a series of specimens collected; and a single individual of Parkesia motacilla (Parulidae) was photographed. All were found in the understory of montane forest at 1000–1550 m elevation. We interpret each of these as most likely representing a regularly occurring population on Mocidade. However, each had probably been overlooked in Brazil for a different reason and represents a distinct distributional pattern. Adding these novelties to Brazil’s previously published total of 1919 species clearly expresses the country’s position among the most bird-rich in the world, perhaps the richest, and suggests that further exploration of Brazil’s Amazonian mountains will yield more discoveries.

“…The uplands and highlands of the Guiana Shield exhibit remarkable biological endemism across taxonomic groups, including vascular plants (Berry & Riina, ), birds (Zyskowski et al., ), herpetofauna (McDiarmid & Donnelly, ) and mammals (Voss, Lim, Diaz‐Nieto, & Jansa, ). Although sampling of fishes is generally sparse at higher altitudes of the Guiana Shield, surveys of the upper Mazaruni and upper Potaro rivers also indicate endemicity and biogeographical isolation.…”

Aim The Guiana Shield region exhibits extraordinary topography that includes sheer, flat‐topped mountains (tepuis) atop an upland platform. Rivers of the eastern Pakaraima Mountains descend to Atlantic coastal lowlands, often traversing spectacular rapids and waterfalls. For fish species distributed in both uplands and lowlands, it is unclear whether these rapids and waterfalls present population or biogeographical boundaries. We sought to test this using the geographically widespread banded‐electric knifefish (Gymnotus carapo) as a model. Location The Guiana Shield region of South America. Methods We sampled 60 Gymnotus carapo specimens from the Guiana Shield region, and 75 G. carapo and closely related species from other parts of South America. We sequenced the mitochondrial cytochrome b gene and an intron from the nuclear S7 ribosomal protein gene, and used maximum likelihood and Bayesian tree‐building approaches to generate phylogenetic trees of haplotypes. Results Haplotype sharing is minimal between populations separated by elevational barriers. We found evidence for two main haplotype clades in the Guiana Shield: one distributed in Atlantic coastal regions that includes most lowland samples, and one inland that includes most upland samples. Inland Guiana samples are more closely related to samples from the Amazon basin than to those of Atlantic coastal regions. A single sample from Tafelberg tepui in Suriname was most closely related to the Atlantic coastal lineages. Main conclusions Riverine barriers that result from steep elevational gradients in the Guiana Shield inhibit gene flow between uplands and lowlands, even for a widely distributed species. Biogeographical relationships of Guiana Shield G. carapo are complex, with most upland lineages showing affinities to the Amazon basin, rather than to nearby lowland drainages of the Atlantic coast.
