Abstract:
Patterns in spatial and trophic resource partitioning in the fish community of the Georges Bank region are identified, accounting for size-based changes in diets. During autumn and spring, this community is divided into geographic assemblages of species that have high spatial overlap. Similarity in spatial distribution is primarily related to similarity in depth preferences, and seasonal differences in species composition within assemblages are related to migrations. There is also important trophic structure within the Georges Bank community separating predators based upon prey size and locati

Niche partitioning studies are essential to understand the mechanisms that allow ecologically similar species to coexist. The Rhone streber (Zingel asper) and the European bullhead (Cottus gobio) are both benthic riverine fishes that consume macroinvertebrates. Both species are protected under European legislature. We focused on trophic niche partitioning between these species, as sufficient access to trophic resources is an important requirement for long-term coexistence.

Coastal salt marshes serve as the margin between terrestrial and marine biomes, provide a variety of important services, and are dynamic ecosystems characterized by keystone species that shape trophic networks. In coastal salt marshes of the Atlantic and Gulf Coasts of the United States, marsh periwinkle snails (Littoraria irrorata) exhibit high abundance and form critical trophic pathways as important herbivores and detritivores. Specifically, snails forage on Spartina alterniflora and associated fungal growth, for which L. irrorata may act as a top-down control on plant growth. Yet, L. irror

Abstract Fomitopsis pinicola [Sw.] P. Karst. is one of the most common wood-decaying macrofungi which is adapted to growth under different environmental conditions, but little is known about its intraspecific variation in spatial distribution, function and substrate specificity in different habitats. To understand how the geographical distribution, trophic mode and host specificity of this fungus vary across different habitat categories, we analysed its habitat and trophic preferences using Slovakia (Central Europe) as an example. For this purpose we studied and compared the archived material

AbstractThe feeding habits of nymphs of Perla marginata (Panzer) and Dinocras cephalotes (Curtis) were investigated in the Rio Orbarina (northwestern Italy). These species are among the largest European carnivorous freshwater invertebrates and they play an important role in the trophic structure of small, fishless Apennine streams. We examined the gut contents of 60 P. marginata and 60 D. cephalotes nymphs to characterize the diets and evaluate possible feeding differences between the species. In both of these predaceous stoneflies, the diet included vegetable detritus, mainly in the smaller i

This study contributes to filling knowledge gaps regarding recent information on the diet of the European hake, Merluccius merluccius Linnaeus, 1758, in the Greek seas, particularly its ontogenetic shifts and its spatiotemporal variability. The trophic preferences of M. merluccius were investigated in the North Aegean Sea during the summers of 2019 to 2023 with visual stomach content analysis to assess its composition, diversity, and variability across body-size classes, years, and subareas. The identified prey are functionally diverse and in many cases also primary targets for local fisheries

Abstract:
Increasing evidence indicates that parasites play an important role within many systems as prey for higher trophic levels. Predation on parasites can decrease their numbers and may affect host infection rates. Cercariae, a free-living infectious stage of trematode parasites, are abundant in freshwater systems and are directly consumed by a number of freshwater predators. However, few studies have tested whether predators exhibit a preference for cercariae when alternative prey are available or how these preferences vary across predator body sizes. We assessed whether dragonfly larvae (dot-tail

The subtidal bottoms of the Ría de Ares-Betanzos are characterized by the dominance of soft, principally sandy substrata. Nevertheless, in the study programme of the molluscs of the ría, five rocky subtidal localities have been sampled. The sample collection was made using the underwater aspiration method by means of SCUBA diving. The studied zones were between 12 and 32 metres deep. The values of diversity (H’) were high, they come up their maximum in the deepest locality E01 (H’= 3.34) and the highest value for equitability (J) was found in E05 (J= 0.75). For this s

However, there is limited research on the top-down effects of mesozooplankton on prey communities. This study conducted seasonal in-situ cultivation experiments from 2015 to 2017.

Our understanding of Hawaiian arboreal snails' diets remains rudimentary, hindering the development of effective conservation strategies. To identify important food resources, we tested the hypothesis that epiphytic microbial assemblages differ on plant species preferred and avoided by snails at Mt.

Comparing microbial assemblages on plants that snails both prefer and avoid was identified as a potentially key step to moving research away from characterizing which microbes snails encounter, towards testin

Post-fledging use of early successional habitat by mature-forest birds is well-documented, but the important trophic factors driving this association remain poorly understood. We used stable isotope analysis of plasma, red blood cells, feces, and feathers to determine foraging preferences of three mature-forest bird species captured in 8-year-old clearcuts during the post-fledging period. We did not identify a significant source contribution in any consumer tissue combination using MixSIAR posterior distributions, but the position of consumer tissues in bivariate isotope mixing space suggested

Better knowledge of food webs and related ecological processes is fundamental to understanding the functional role of biodiversity in ecosystems. This is particularly true for pest regulation by natural enemies in agroecosystems. However, it is generally difficult to decipher the impact of predators, as they often leave no direct evidence of their activity. Metabarcoding via high-throughput sequencing (HTS) offers new opportunities for unraveling trophic linkages between generalist predators and their prey, and ultimately identifying key ecological drivers of natural pest regulation.

In an analysis of the gut contents of 84 nymphs, we detected evident trophic preferences: Chironomidae (Diptera) were the major component of the prey ingested, independently of their availability in the substratum. Plant detritus and algae were also an important part of the diet of this carnivorous stonefly. The findings are discussed on the basis of ecological considerations.
