Crater lake cichlids individually specialize along the benthic-limnetic axis [PDF]
A common pattern of adaptive diversification in freshwater fishes is the repeated evolution of elongated open water (limnetic) species and high-bodied shore (benthic) species from generalist ancestors.

Drivers of parasite sharing among Neotropical freshwater fishes [PDF]
SummaryBecause host–parasite interactions are so ubiquitous, it is of primary interest for ecologists to understand the factors that generate, maintain and constrain these associations. Phylogenetic comparative studies have found abundant evidence for host‐switching to relatively unrelated hosts, sometimes related to diversification events, in a ...

Swimming performance of the small characin Bryconamericus stramineus (Characiformes: Characidae)
Very little research has been conducted on the swimming capacity of Neotropical fish. The few studies available have focused on large migratory species.

C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae) [PDF]
Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, namely A.

The response of neotropical dragonflies (Insecta: Odonata) to local and regional abiotic factors in small streams of the Amazon [PDF]
Since the relative role of local and regional abiotic factors on the Odonata diversity in rainforest streams is still poorly understood, we evaluated the effects of these factors on adult Odonata (Insecta) from preserved and altered streams in the ...

Optimal swim speeds by respirometer: an analysis of three neotropical species
The swimming ability of neotropical fish species is an important aspect for fish ladder designs. Especially in Latin America, where fish ladders are highly selective, fish strategies to negotiate the passage should be studied focusing on target species ...

Phylogenetic analysis of microbial communities in different regions of the gastrointestinal tract in Panaque nigrolineatus, a wood-eating fish [PDF]
The Neotropical detritivorous catfish Panaque nigrolineatus imbibes large quantities of wood as part of its diet. Due to the interest in cellulose, hemi-cellulose and lignin degradation pathways, this organism provides an interesting model system for the
