Isotopic niche partitioning in two sympatric howler monkey species.
Sign Up to like & getrecommendations! Published in 2020 at "American journal of physical anthropology"
DOI: 10.1002/ajpa.24028
Abstract: OBJECTIVES Ecological similarity between species can lead to interspecific trophic competition. However, when ecologically similar species coexist, they may differ in foraging strategies and habitat use, which can lead to niche partitioning. As the body… read more here.

DOI: 10.1007/s00227-019-3483-7
Abstract: Quantifying individual specialization and other forms of intraspecific ecological diversity can reveal variation that is critical for evolutionary or behavioral adaption of a species to changing environments. Here, the isotopic niche and degree of individual… read more here.

DOI: 10.1007/s00442-020-04654-4
Abstract: The development of the isotopic niche, an n -dimensional hypervolume (with n being the number of isotopes) occupied by a population in delta space, has revolutionized the study of animal interactions in wild populations. While… read more here.

DOI: 10.1007/s10641-019-00923-1
Abstract: Along the Pacific coast of Baja California Sur (PCBCS), the banded guitarfish (Zapteryx exasperata), shovelnose guitarfish (Pseudobatos productus) and bat ray (Myliobatis californica) are highly abundant. Their ecological roles as predators in demersal communities can… read more here.

DOI: 10.1111/2041-210x.12887
Abstract: Quantitative analytical approaches for isotopic niche analysis in the trophic diversity studies are proliferating rapidly; however, the assumptions behind the isotopic niche applications are rarely tested. One of the main assumptions is independence of the… read more here.

DOI: 10.1111/fwb.12910
Abstract: 1. The crossing of freshwater ecosystem boundaries by marine derived nutrients (MDN) is usually associated with migratory salmonid fishes returning to natal rivers. An alternative source of MDN in freshwaters is the widespread use of… read more here.

DOI: 10.1111/jfb.15217
Abstract: Examples of parasite-related effects on intermediate crustacean hosts are numerous but their ecological consequences on their vertebrate hosts are scarce. Here, we address the role of macroparasite infections on the trophic niche structure of definitive… read more here.
