Preliminary Study on Host Use and Phylogenetic Analysis of <i>Corethrella nippon</i> in Taiwan. [PDF]

open access: yesEcol Evol
This study evaluated a new frog‐calling trap in Taiwan that successfully collected the species of Culicidae and Corethrellidae and identified host preferences, with Corethrellidae most frequently associated with Odorrana swinhoana and Kurixalus eiffingeri (mostly attracted to ~2022 Hz calls).

Pelagic distribution and night foraging of early juvenile European catfish (Silurus glanis L.). [PDF]

open access: yesJ Fish Biol
Abstract This study provides evidence of pelagic occurrence and night feeding in early juvenile European catfish that contributed 0.2% to the early juvenile pelagic community at night in Klíčava, 0.3% in Římov, and 3.3% in Žlutice Reservoirs in the Czech Republic. The catfish occurred mostly at a depth of 2–4 m. Their abundance was 5.5 inds.1000 m−3 in

Habitat Complexity Reduces the Feeding Strength of Freshwater Predators. [PDF]

open access: yesEcol Evol
We investigated how habitat complexity influences the feeding responses of an ambush predator (Ischnura elegans) and a pursuit predator (Notonecta glauca) preying on Asellus aquaticus. Feeding rates of I. elegans were primarily affected by the presence or absence of structure, whereas N.

Chaoborus and gasterosteus anti-predator responses in Daphnia pulex are mediated by independent cholinergic and gabaergic neuronal signals. [PDF]

open access: yesPLoS ONE, 2012
Many prey species evolved inducible defense strategies that protect effectively against predation threats. Especially the crustacean Daphnia emerged as a model system for studying the ecology and evolution of inducible defenses. Daphnia pulex e.g.

Reduced intraspecific variation in lake trout food webs under warmer temperatures and smaller ecosystem sizes. [PDF]

open access: yesEcology
Abstract Food web theory has illustrated that mobile top predators, such as lake trout (Salvelinus namaycush), can be potent stabilizers of food webs due to their ability to shift foraging behaviors in response to changing conditions. Consistent with this, research has demonstrated that mean lake trout food web attributes (i.e., trophic position and ...

Density- and size-dependent winter mortality and growth of late Chaoborus flavicans larvae. [PDF]

open access: yesPLoS ONE, 2013
Winter processes such as overwinter survival and growth of individuals can have wide-ranging consequences for population dynamics and communities within and across seasons. In freshwater organisms winter processes have been mainly studied in fish despite

Water mite predation on zooplankton of a tropical lake [PDF]

open access: yesBrazilian Journal of Biology, 2002
Water mite (Krendowskia sp.) predation on zooplanktonic species from Lake Monte Alegre (São Paulo State, Brazil) was tested in laboratory experiments. One cladoceran, Daphnia gessneri, two copepods, Tropocyclops prasinus and Thermocyclops decipiens, and ...

Factors affecting methylmercury biomagnification by a widespread aquatic invertebrate predator, the phantom midge larvae Chaoborus [PDF]

open access: yes, 2012
MeHg biomagnification by the phantom midge Chaoborus in relation to MeHg concentrations in their prey and its migratory behavior was investigated in two Canadian Precambrian Shield lakes.

Quantification of Chaoborus and small fish by mobile upward-looking echosounding

open access: yesJournal of Limnology, 2018
Chaoborus larvae inhabit frequently the water column of lakes, when they can be mistaken for small fish. Because larvae ascend up to the blind zone of downward-looking echo sounding at night, quantitative acoustic estimation of them is possible only with
