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.

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.

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.

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.

Abstract: A 125-year record of seabird trophic status shows declines reflecting squid boom and improves on prior index deficiencies. Pelagic ecosystems are dynamic ocean regions whose immense natural capital is affected by climate change, pollution, and… read more here.
