More intense predation in the tropics can limit marine invasions
biological invasion biodiversity tropics
2021/8/5
Marine biologists tested predictions about biological invasions, first in Panama and then in an experiment of unprecedented geographic scale.
Vulnerability of Logfin Inshore Squid (Loligo Pealeii) to Predation: The Influence of Relative Prey Size and Behavior
Marine Predation Size-selection
2014/10/23
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...
Predation of threespine stickleback (Gasterosteus aculeatus) on the eggs of Atlantic herring (Clupea harengus) in a Baltic Sea lagoon
Predation of threespine stickleback Atlantic herring
2014/4/2
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...
Food web consequences of size-based predation and vertical migration of an invertebrate predator (Leptodora kindtii)
size-based predation an invertebrate predator
2014/4/2
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...
Zooplankton vertical migration and plasticity of pigmentation arising from simultaneous UV and predation threats
Zooplankton vertical migration plasticity of pigmentation arising simultaneous UV predation threats
2014/4/17
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...
Does predation control adult sex ratios and longevities in marine pelagic copepods?
predation contro adult sex ratios longevities marine pelagic copepods
2014/4/16
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...
Response of the invertebrate predator Bythotrephes to a climate-linked increase in the duration of a refuge from fish predation
Response of the invertebrate predator Bythotrephes climate-linked increase duration of a refuge fish predation
2014/4/17
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...
UV-enhanced fish predation and the differential migration of zooplankton in response to UV radiation and fish
UV-enhanced fish predation zooplankton
2014/4/18
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...
Vertical distribution of zooplankton in subalpine and alpine lakes: Ultraviolet radiation, fish predation, and the transparency-gradient hypothesis
Vertical distribution of zooplankton subalpine and alpine lakes Ultraviolet radiation fish predation, the transparency-gradient hypothesis
2014/4/21
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...
The Development, Predation, and Reproduction of Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae) from Hatay Fed Tetranychus cinnabarinus Boisduval (Acari: Tetranychidae) Larvae and Protonymphs at Different Temperatures
Phytoseiulus persimilis Tetranychus cinnabarinus development temperature food consumption
2010/3/26
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...

Consequences of fish predation, migration, and juvenile ontogeny on zooplankton spring dynamics
Consequences of fish predation migration juvenile ontogeny zooplankton spring dynamics
2014/4/23
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...
Virus predation by sponges is a new nutrient-flow pathway in coral reef food webs
Virus predation by sponges new nutrient-flow pathway coral reef food webs
2014/5/4
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...
Solar radiation-nutrient interaction enhances the resource and predation algal control on bacterioplankton: A short-term experimental study
