Published in 2024 at "Aquatic Conservation: Marine and Freshwater Ecosystems"

DOI: 10.1002/aqc.4103

Abstract: Despite supporting a disproportionately large fraction of the global biodiversity, freshwater ecosystems are ranked as the most highly threatened habitats ahead of both terrestrial and marine ecosystems. Furthermore, many regions are still characterized by limited… read more here.

Published in 2022 at "Ecology and Evolution"

DOI: 10.1002/ece3.8742

Abstract: Abstract Documenting trophic niche partitioning and resource use within a community is critical to evaluate underlying mechanisms of coexistence, competition, or predation. Detailed knowledge about foraging is essential as it may influence the vital rates,… read more here.

Published in 2018 at "Ecosphere"

DOI: 10.1002/ecs2.2080

Abstract: Over the last 100 yr, anthropogenic stressors have decimated the assemblage of deepwater coregonines that once underpinned the food webs of the Laurentian Great Lakes. As a part of ongoing restoration efforts, fisheries managers are… read more here.

Published in 2024 at "Ecosphere"

DOI: 10.1002/ecs2.4887

Abstract: Understanding the trophic and demographic dynamics of apex predators is of paramount importance for ecosystem conservation. Apex predators are usually free from predation, and thus, the main driver of population dynamics is the availability of… read more here.

Published in 2017 at "Limnology and Oceanography"

DOI: 10.1002/lno.10546

Abstract: Sponges are commonly divided into high (HMA) and low (LMA) microbial-abundance species according to the bacterial biomass in their tissue. These two groups reflect distinct aquiferous structures and feeding strategies. In the NW Mediterranean coralligenous… read more here.

Published in 2025 at "Oikos"

DOI: 10.1002/oik.11324

Abstract: 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… read more here.

Published in 2018 at "Aquatic Ecology"

DOI: 10.1007/s10452-018-9663-6

Abstract: Niche theory predicts that sympatric species should differ in some ecological characteristic, to allow co-existence and reduce competition for key resources. Food is critical on wintering grounds and stopover areas for migratory species that need… read more here.

Published in 2024 at "Biological Invasions"

DOI: 10.1007/s10530-024-03250-4

Abstract: The introduction of non-native species to a new environment poses a threat to local biological diversity, causing instability in the functioning of the ecosystem. The ecological effects caused by these species have been scarcely documented… read more here.

Published in 2024 at "Biological Invasions"

DOI: 10.1007/s10530-024-03444-w

Abstract: The Florida Everglades is a critically important, but highly threatened ecosystem that is becoming increasingly susceptible to the invasion of non-native species. This study investigated the ecological role of the invasive peacock eel (Macrognathus siamensis)… read more here.

Published in 2019 at "Hydrobiologia"

DOI: 10.1007/s10750-019-3969-9

Abstract: Parallelism in trophic niches of polymorphic populations of Arctic charr was investigated in two similar subarctic lakes, Tårnvatn and Skøvatn, in northern Norway. Analysis of eleven microsatellite loci confirmed, respectively, the existence of three and… read more here.

Published in 2020 at "Aquaculture"

DOI: 10.1016/j.aquaculture.2020.735162

Abstract: Abstract In temperate fish polyculture, common carp (Cyprinus carpio) and roach (Rutilus rutilus) are two fish species commonly reared in the same ponds. In the natural environment, these two species are considered omnivorous and may… read more here.
