Alarm cue induces an antipredator morphological defense in juvenile Nicaragua cichlids Hypsophrys nicaraguensis [PDF]
Current Zoology, 2010 Olfactory cues that indicate predation risk elicit a number of defensive behaviors in fishes, but whether they are sufficient to also induce morphological defenses has received little attention. Cichlids are characterized by a high level of morphological

In search of new brain biomarkers of stress [PDF]
Research Results in Pharmacology, 2021 The aim: of the study was to investigate the level of ghrelin in various brain structures during a stress response in Zebrafish to a predator, to evaluate this indicator as a potential biomarker of stress, and the effect of a benzodiazepine tranquilizer (

Similarities in biological processes can be used to bridge ecology and molecular biology. [PDF]
Evol Appl, 2020 Abstract Much of the research in biology aims to understand the origin of diversity. Naturally, ecological diversity was the first object of study, but we now have the necessary tools to probe diversity at molecular scales. The inherent differences in how we study diversity at different scales caused the disciplines of biology to be organized around ...

Ecological and evolutionary consequences of selective interspecific information use [PDF]
Ecology Letters, Volume 26, Issue 4, Page 490-503, April 2023., 2023 Recent work has shown that animals frequently use social information from individuals of their own species as well as of other species, yet the consequences of social information use remain poorly understood. Furthermore, information users may be selective in their social information use, deciding from whom and how to use information, but this has been

Habitat light sets the boundaries for the rapid evolution of cichlid fish vision, while sexual selection can tune it within those limits [PDF]
Molecular Ecology, Volume 29, Issue 8, Page 1476-1493, April 2020., 2020 Abstract Cichlid fishes' famous diversity in body coloration is accompanied by a highly diverse and complex visual system. Although cichlids possess an unusually high number of seven cone opsin genes, they express only a subset of these during their ontogeny, accounting for their astonishing interspecific variation in visual sensitivities. Much of this

International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011 Lowland streams of the Caribbean Costa Rican slope are naturally enriched by minerals and solutes such as phosphorus, a phenomenon known as geothermal input. The resulting stream phosphorus gradient affects the food web by altering primary production, leading to complex biotic and abiotic interactions.
