The Aggregation of Fish in the Metalimnion Constrains Zooplankton Diel Vertical Migration

open access: yesFreshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The role of fish predation in zooplankton diel vertical migration (DVM) is well established, where zooplankton move to deep waters during the day—to hide from visual predators in surface layers—and return to the epilimnion at night (i.e., ‘normal’ DVM), to feed on phytoplankton.

Plankton vertical migrations - Implications for the pelagic ecosystem

open access: yes, 2011
Habitat selection is an important behavior of many organisms. The direction and strength of this behavior is often characterized as a result of a trade off between predator avoidance and obtaining resources. A characteristic example of this trade off may

These Boots Are Made for Walking: Sex‐Specific Physiological and Metabolomic Strategies Reflect Male‐Skewed Vulnerability to Ocean Warming in a Keystone Amphipod

open access: yesGlobal Change Biology, Volume 32, Issue 6, June 2026.
Sex‐specific responses to ocean warming shape thermal tolerance, fitness, and metabolomic profiles in a keystone amphipod. Females exhibit higher thermal limits and broader safety margins than males. Warming reduces survival and reproductive output, while it increases offspring size.

The Role of Inducible Defence in Ecological Models: Effects of Nonlocal Intraspecific Competition

open access: yesStudies in Applied Mathematics, Volume 156, Issue 6, June 2026.
ABSTRACT Phenotypic plasticity significantly influences species interactions, especially via inducible defensive mechanisms in predator–prey dynamics. This work proposes and explores a predator–prey scenario whereby the prey species demonstrates inducible defence mechanisms against predators.

Potential role of methane-derived carbon as a food source for Daphnia in a North Carolina reservoir [PDF]

open access: yes, 2010
Herbivorous zooplankton feed on seston, including algal, detrital, and bacterial components. However, many studies have found that Daphnia del13C is more depleted than seston del13C, and selective feeding on seston algal components has been hypothesized.

O uso de biomarcadores para avaliar o impacto ambiental de contaminantes em rios Mediterrâneos

open access: yes, 2010
Doutoramento em BiologiaUm assunto que requer atenção é a avaliação ecológica da qualidade da água de ecossistemas de água doce. Uma abordagem que surge como promissora é a biomonitorização baseada em biomarcadores, porque pode avaliar a saúde dos ...
