TL;DR: Large rails discovered in the mangroves along the Pacific coast of Honduras are described as a new subspecies, the Fonseca Mangrove Rail (R. l. berryorum) because of past confusion over species limits in the Clapper Rail complex.

TL;DR: The discovery of slate-throated redstarts breeding in the Maderas del Carmen mountains in Coahuila is reported, which represents a range extension of approximately 400 km and is, to the authors' knowledge, the northernmost breeding record for this species.

TL;DR: Although the phylogenetic relationships among the studied species was poorly supported, dating confirmed that they diverged during the Pleistocene, suggesting that phytotelm breeding could have arisen during drier periods in the glacial/interglacial cycles due to a decrease in the availability of permanent streams or ephemeral/temporary streams or ponds in which Melanophryniscus species commonly breed.

TL;DR: Several variants under selection scattered across the genome are identified, suggesting that local adaptation can promote rapid differentiation over short periods when acting over multiple independent loci.

TL;DR: In this article, the authors examined the genetic structure of Sceloporus subniger and found that it is indeed a composite of several distinct species, which supports the notion that S.subniger is a composite species of distinct species.
