Diet and trophic groups of an aquatic insect community in a tropical stream [PDF]

open access: yesBrazilian Journal of Biology, 2004
The diet and trophic groups of an assemblage of aquatic insects were studied in a tropical stream. Genera of the orders Ephemeroptera, Odonata, Plecoptera, Lepidoptera, and Hemiptera showed feeding specialization. Others, such as Trichoptera, Coleoptera,

Trophic groups and modules: two levels of group detection in food webs. [PDF]

open access: yesJ R Soc Interface, 2015
Within food webs, species can be partitioned into groups according to various criteria. Two notions have received particular attention: trophic groups (TGs), which have been used for decades in the ecological literature, and more recently, modules. The relationship between these two group concepts remains unknown in empirical food webs.

Energetic differences between bacterioplankton trophic groups and coral reef resistance. [PDF]

open access: yesProc Biol Sci, 2016
Coral reefs are among the most productive and diverse marine ecosystems on the Earth. They are also particularly sensitive to changing energetic requirements by different trophic levels. Microbialization specifically refers to the increase in the energetic metabolic demands of microbes relative to macrobes and is significantly correlated with ...

Vegetation and Soil Aggregates Shape Nematode Communities and Energy Flow on the Loess Plateau [PDF]

open access: yesMicroorganisms
Although soil nematodes are central to belowground energy flow, how vegetation and soil aggregate characteristics interactively regulate the nematode community structure and energy dynamics remains poorly understood.

Insect invasion success depends on taxon and trophic group [PDF]

open access: yesNeoBiota
The majority of non-native animal species globally are insects, though some insect species are more successful invaders than others. These differences can be attributed, in part, to differences among dominant trophic groups.

Late Permian ichthyofauna from the North-Sudetic Basin, SW Poland [PDF]

open access: yesActa Palaeontologica Polonica, 2021
The late Permian time was a transformative period before the most severe mass extinction known. Even though fishes constitute a key component of marine ecosystems since the Silurian, their biogeographic patterns during the late Permian are currently ...

Trophic Structure of Neuston Across Tropical and Subtropical Oceanic Provinces Assessed With Stable Isotopes

open access: yesFrontiers in Marine Science, 2021
The marine neuston, organisms living in the vicinity of the ocean surface, is one of the least studied zooplankton groups. Neuston occupies a restricted ecological niche and is affected by a wide range of endogenous and exogenous processes while also ...

Taxonomic diversity of litter and soil invertebrates and the structure of dominance of their communities under the influence of natural afforestation of model plots in Western Polissia

open access: yesБіологічні студії, 2023
Background. Composition of tree species plays an important role in the structural and functional organization of soil invertebrates during the process of afforestation, which affects the trophic structure of soil invertebrate communities.
