The Anatomical Record, EarlyView.Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Effect of land use on soil nematode community composition and co-occurrence network relationship
Journal of Integrative AgricultureLand use influences soil biota community composition and diversity, and then belowground ecosystem processes and functions. To characterize the effect of land use on soil biota, soil nematode communities in crop land, forest land and fallow land were ...

EcoTran trophic network of non-detritus groups by trophic level.
The EcoTran trophic network is visualized here as a weighted, directed graph with detritus groups (86–90) removed (see Fig 6). Numbered nodes are functional groups (see Table 1 for numbers); arrows indicate directed edges (energy flows from producer ...

The Anatomical Record, EarlyView.Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

Macroinvertebrate trophic groups in an andean wetland of colombia
, 2013 In the wetland Jaboque (Bogotá, Colombia) the physical and chemical properties of the water and the food dietary guilds of the aquatic macroinvertebrate community were analyzed from April 2009 to January 2010. The wetland waters had a slightly acid character with high values of nitrate, ammonia and orthophosphate, so this ecosystem is classified as ...

Predation on marine bryozoan colonies: taxa, traits and trophic groups [PDF]
Marine Ecology Progress Series, 2008 While bryozoans are important components of marine benthic ecosystems, their sig- nificance as food has scarcely been considered in any comparative study. An analysis of the phylo- genetic range of predators on bryozoan colonies was undertaken to elucidate relationships among different consumers.

The Anatomical Record, EarlyView.The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

An ecosystem model of San Pedro Bay, Leyte, Philippines: initial parameter estimates [PDF]
A mass-balance model of the trophic structure of San Pedro Bay, Leyte Province, Philippines was constructed using the Ecopath modeling software. The model is composed of 16 ecological groups (13 consumer, 2 producers, 1 detritus groups).
