recommendations! Published in 2023 at "Ecology and Evolution"

DOI: 10.1002/ece3.10000

Abstract: Abstract Associating morphological features with ecological traits is essential for understanding the connection between organisms and their roles in the environment. If applied successfully, functional trait approaches link form and function in an organism. However,… read more here.

DOI: 10.1002/ece3.11370

Abstract: Abstract Habitat loss and degradation are key drivers of the current biodiversity crisis. Most research focuses on the question of which traits allow species to persist in degraded habitats. We asked whether a species' trophic… read more here.

DOI: 10.1002/ece3.11620

Abstract: Abstract Assessments of ecosystem functioning are a fundamental ecological challenge and an essential foundation for ecosystem‐based management. Species trophic position (TP) is essential to characterize food web architecture. However, despite the intuitive nature of the… read more here.

DOI: 10.1002/ece3.9087

Abstract: Abstract An organism's body size plays an important role in ecological interactions such as predator–prey relationships. As predators are typically larger than their prey, this often leads to a strong positive relationship between body size… read more here.

DOI: 10.1002/ecs2.4944

Abstract: Nitrogen isotope analyses of amino acids (δ15N‐AA) are being increasingly used to decipher trophic dynamics. Interpretation of δ15N‐AA in consumers relies on the assumption that consumer physiological status and nutritional status of prey have negligible… read more here.

DOI: 10.1002/ecy.3865

Abstract: Understanding the response of predators to ecological change at multiple temporal scales can elucidate critical predator-prey dynamics that would otherwise go unrecognized. We performed compound-specific nitrogen stable isotope analysis (CSIA) of amino acids on 153… read more here.

A giant's appetite: how body size drives the diet and trophic position of the Japanese giant salamander

recommendations! Published in 2025 at "Oikos"

DOI: 10.1002/oik.11831

Abstract: In predators, growth often drives ontogenetic dietary shifts (ODSs), leading to increasing trophic position (TP) with body size as growing individuals gradually incorporate larger prey in their diet. In species exhibiting extreme size variation, particularly… read more here.

DOI: 10.1007/s00442-020-04752-3

Abstract: Body size, trophic position (TP), and trophic niche width are important elements of food webs; however, there is still debate regarding their interrelationships. Most studies have tested these correlations using datasets restricted to carnivores and… read more here.

DOI: 10.1016/j.jglr.2020.03.017

Abstract: Abstract Accurate trophic position (TP) estimates are important for the development of ecosystem-based management plans. TPs can be quantified by carbon (δ13C) and nitrogen (δ15N) stable isotopes in tissues, but these can disagree with observed… read more here.

DOI: 10.1098/rsos.160645

Abstract: Body size is frequently claimed to be a major determinant of animal trophic interactions, yet few studies have explored relationships between body size and trophic interactions in rivers, especially within the tropics. We examined relationships… read more here.

DOI: 10.1111/ecog.04307

Abstract: The energetic demand of consumers increases with body size and temperature. This implies that energetic constraints may limit the trophic position of larger consumers, which is expected to be lower in tropical than in temperate… read more here.
