Marine biologists tested predictions about biological invasions, first in Panama and then in an experiment of unprecedented geographic scale.
Cephalopods provide forage to a wide range of predators in marine food-webs. Despite their ecological importance, a basic understanding of the mechanisms controlling predation risk and demand is lacki...
We analyzed the predation of threespine stickleback (Gasterosteus aculeatus) on the spawn of Atlantic herring (Clupea harengus) in a mesohaline lagoon of the Baltic Sea, hypothesizing a significant p...
In an intensive study of the vertical and horizontal distribution of zooplankton in a eutrophic lake (Katepwa Lake), we found that only adult Leptodora kindtii (. 5 mm in body size) exhibited diel ve...
We assessed how zooplankton (copepods) handle the simultaneous threats of predators and ultraviolet (UV) radiation and whether they respond with changes in pigmentation, vertical migration, or both. W...
We assess the causes of adult sex ratio skew in marine pelagic copepods by examining changes in these ratios between the juveniles and adults, sexual differences in juvenile stage durations, and morta...
Climate warming can affect ecological food chains directly by increasing the rates of physiological processes and indirectly by changing habitat use and altering predator-prey interactions. In Lake Ma...
The intensity and spectral composition of visible light are known to influence fish predation on zooplankton. However, in clear-water systems, ultraviolet (UV) radiation (UVR) may also influence fish...
The transparency-gradient hypothesis argues that ultraviolet radiation (UV) is a primary determinant of the vertical distribution of zooplankton in transparent lakes with fewer fish, while fish predat...
Developmental time, predation, and reproduction of Phytoseiulus persimilis Athias-Henriot from Hatay on a diet of Tetranychus cinnabarinus Boisduval larvae and protonymphs at temperatures of 20, 25, a...
The transparency-gradient hypothesis argues that ultraviolet radiation (UV) is a primary determinant of the vertical distribution of zooplankton in transparent lakes with fewer fish, while fish predat...
In order to disentangle if and when resource supply and adult and young-of-the-year (0+) fish predation affect zooplankton dynamics during spring, we monitored zooplankton during three consecutive yea...
The removal efficiency of viral particles by the coral reef sponge Negombata magnifica was measured. Virus particles were removed by the sponge at an average efficiency of 23.3% ± 2.9%. Significant am...
An in situ experimental assessment was made of the effects of the interaction between spectral composition of solar radiation and the limiting nutrient (phosphorous, P) on the algae-bacteria link, mea...
We assessed the trophic status of Leptodora kindtii in the food web of a shallow, eutrophic lake in which 0+ age group fish were the main predators. The mean biomass of 0+ fish during three successive...
