Omnivory by the Small Cosmopolitan Hydromedusa Aglaura Hemistoma [PDF]

, 2005
We investigated the feeding of the small hydromedusa, Aglaura hemistoma (bell diameter \u3c 4 mm), to determine if it occupies a trophic position similar to that of large medusae.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

Biological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Trophic plasticity and invasive success: dynamic feeding strategies of the signal crayfish in Croatian rivers

Journal of Freshwater Ecology
The invasive signal crayfish (Pacifastacus leniusculus), a species of high concern in European freshwaters, represents a substantial threat to native crayfish species and freshwater ecosystems.

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Ecomorphology and use of food resources: inter- and intraspecific relationships of fish fauna associated with macrophyte stands

Neotropical Ichthyology
Based on the form-function interaction and its consequence to niche exploitation by fish species, the study aimed to identify ecomorphological patterns and to investigate the possibility of explaining the trophic niche breadth using the pattern of ...

Diet of the weasel in Hungary [PDF]

, 2007
The diet of weasel (Mustela nivalis) collected in agricultural mosaic plain regions of Hugary was studied using the analysis of stomach and rectum contents (n = 155).

Studying interspecific population synchrony: current status and future perspectives

Ecography, EarlyView.
Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

Trophic niche overlap decreases in related mesocarnivore species

Oikos
In natural environments, competition between species is a crucial factor for the survival or demise of populations. Therefore, understanding the mechanisms that promote species coexistence is crucial in community and evolutionary ecology. The phylogenetic limiting to similarity hypothesis (PLSH) posits that closely related species should experience ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.
