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 (

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

Heterospecific aggression bias towards a rarer colour morph. [PDF]
Proc Biol Sci, 2015 Colour polymorphisms are a striking example of phenotypic diversity, yet the sources of selection that allow different morphs to persist within populations remain poorly understood.

Aggression towards shared enemies by heterospecific and conspecific cichlid fish neighbours. [PDF]
Oecologia, 2019 Successful territory defence is a prerequisite for reproduction across many taxa, and often highly sensitive to the actions of territorial neighbours. Nevertheless, to date, assessments of the significance of the behaviour of heterospecific neighbours ...

The imperiled fish fauna in the Nicaragua Canal zone. [PDF]
Conserv Biol, 2017 Large‐scale infrastructure projects commonly have large effects on the environment. The planned construction of the Nicaragua Canal will irreversibly alter the aquatic environment of Nicaragua in many ways.

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 ...

Allopatry, competitor recognition and heterospecific aggression in crater lake cichlids. [PDF]
BMC Evol Biol, 2016 Aggressive behaviour can have significant evolutionary consequences–not only within species, but also in the context of heterospecific interactions. Here, we carried out an experimental field study to investigate the importance of phenotypic similarity ...
