Testing the Optimal Foraging Theory in a Generalist Feeder: The Case of Reintroduced European Pond Turtles and Its Impact on Macroinvertebrates Communities. [PDF]

Ecol Evol
In this study we investigated the macroinvertebrate (MI) communities in two newly created, man‐made ponds concurrently with the diet of captive‐bred European pond turtles that were translocated there. We aimed at assessing whether turtles were operating as generalist feeders, and if successive reintroductions of turtles would affect the overall MI ...

Relative Effects of Eutrophication and Warming on Freshwater Ecosystems Across Ecological Levels. [PDF]

Glob Chang Biol
This experimental study explores the effects of global change on different ecological levels. We demonstrate that warming primarily impacts lower ecological levels, such as community composition, whereas eutrophication predominantly affects the most integrative ecological level, that is, ecosystem.

Complex landscapes, complex diets: DNA metabarcoding reveals lady beetle prey richness increases with landcover diversity. [PDF]

Ecol Appl
Abstract Understanding the capacity of mobile organisms such as insects to utilize resources across different patches in a landscape can reveal strategies for their conservation. Past research suggests that higher levels of non‐crop habitat or landcover diversity in agricultural regions typically benefit generalist predators who can fortify their diets

The Role of Artificial Lakes Located in Forests in the Context of Small Retention, Biodiversity and Climatic Changes-Evidence From Southern Poland. [PDF]

Ecol Evol
The model of plant associations showed the occurrence of 24 species of plants within nine plant assemblages in the Phragmitetea and Potametea classes of associations. Despite human activities, lake condition, as assessed by the ESMI index or the biocenotic diversity indices, is good.

Exploring the efficacy of predacious diving beetles as potential nature-based solution for combatting the invasive mosquito Aedes albopictus (Skuse, 1894) [PDF]

NeoBiota
The invasive mosquito species Aedes albopictus (Skuse, 1894) is rapidly spreading in Europe, posing an increasing threat because of its high vector competence for chikungunya and dengue virus.

Diel vertical migration patterns in two populations of Chaoborus flavicans larvae (Diptera: Chaoboridae) in response to fish kairomones

Journal of Limnology, 2008
Diel vertical migration (DVM) of larvae of the phantom midge Chaoborus flavicans (Diptera: Chaoboridae) inhabiting a fishless pond and a fish-abundant lake (Lake Nakanuma) was studied in the field and in the laboratory.
