Not all jellyfish are equal: isotopic evidence for inter- and intraspecific variation in jellyfish trophic ecology [PDF]
PeerJ, 2015 Jellyfish are highly topical within studies of pelagic food-webs and there is a growing realisation that their role is more complex than once thought.

ATNr: Allometric Trophic Network models in R
Methods in Ecology and Evolution, 2023 Understanding and predicting how densities of interacting species change over time has been one of the main goals of community ecology, which has become a pressing challenge in the context of global change.

Vertical Stratification Increases the Capacity of Morphological Traits to Predict Trophic Position in Neotropical Ants [PDF]
Ecology and EvolutionMorphology is a key functional trait that influences the ecophysiology of organisms. The use of morphological traits for understanding functional ecology is common in studies of ants, especially relating to their feeding biology.

Trophic assessment of four tropical reservoirs using phytoplankton genera
Acta Limnologica Brasiliensia, 2022 : Aim Monitoring the trophic state of reservoirs requires indices that provide a quick report of the ecosystem to decision makers. This study aimed to develop a system of trophic status indicators for tropical mountain reservoirs using phytoplankton ...

Scientific Reports, 2021 Ecological systems show a variety of characteristic patterns of biodiversity in space and time. It is a challenge for theory to find models that can reproduce and explain the observed patterns. Since the advent of island biogeography these models revolve

Arctic Science, 2022 Climate-driven impacts on marine trophic pathways worldwide are compounded by sea-ice loss at northern latitudes. For the Arctic, current information describing food-web linkages is fragmented, and there is a need for tools that can describe overarching ...

Frontiers in Ecology and Evolution, 2021 The functional response (trophic function or individual ration) quantifies the average amount of prey consumed per unit of time by a single predator. Since the seminal Lotka-Volterra model, it is a key element of the predation theory.

Food-web models predict species abundances in response to habitat change. [PDF]
PLoS Biology, 2006 Plant and animal population sizes inevitably change following habitat loss, but the mechanisms underlying these changes are poorly understood. We experimentally altered habitat volume and eliminated top trophic levels of the food web of invertebrates ...

Less need for differentiation? Intestinal length of reptiles as compared to mammals.
PLoS ONE, 2021 Although relationships between intestinal morphology between trophic groups in reptiles are widely assumed and represent a cornerstone of ecomorphological narratives, few comparative approaches actually tested this hypothesis on a larger scale.

On the role of millet in the Don forest-steppe region population diet in the Bronze and Early Iron Age according to bioarchaeological studies [PDF]
Вестник археологии, антропологии и этнографииThe purpose of this study is to find out in what historical period millet penetrates the forest-steppe Don region (Central Black Earth Region) and becomes the basis of the plant diet of region population. For this purpose, an isotope analysis was carried
