Body size predicts ontogenetic nitrogen stable-isotope (δ 15N) variation, but has little relationship with trophic level in ectotherm vertebrate predators

Bunn, Adriana Malvasio, Carlos Ignacio Piña, Cristina Mariana Jacobi, Diogo Dutra Araújo, Elizângela Silva de Brito, Felipe de Moraes Carvalho, Igor David da Costa, Luciano Martins Verdade, Neliton Lara, Plínio Barbosa de Camargo, Priscila Saikoski Miorando, Thiago Costa Gonçalves Portelinha, Thiago Simon Marques, William E. Magnusson

Abstract Large predators have disproportionate effects on their underlying food webs. Thus, appropriately assigning trophic positions has important conservation implications both for the predators themselves and for their prey. Large-bodied predators

Autor: Altin Ghojoghi, Rasoul Ghorbani, Rahman Patimar, Abdolrassoul Salmanmahiny, Rahmat Naddafi, Abdolazim Fazel, Timothy D. Jardine

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-12 (2023)

Abstract This study investigated the Zarrin-Gol River ecosystem in Iran to trace organic matter in the food web and evaluate the impact of aquaculture farm effluent using stable isotopes of nitrogen (δ15N) and carbon (δ13C). Using a previously-deve

River rhythmicity: A conceptual means of understanding and leveraging the relational values of rivers

Autor: Sue Jackson, Elizabeth P. Anderson, Natalia C. Piland, Solomon Carriere, Lilia Java, Timothy D. Jardine

Publikováno v: People and Nature, Vol 4, Iss 4, Pp 949-962 (2022)

Abstract River rhythmicity refers to the periodic, recurrent phenomena of a riverscape that are synchronized with the rise and fall of river water, creating regimes of river time. River rhythmicity can serve as a lens into the temporal dimension of r

A catastrophic coal mine spill in the Athabasca River watershed induces isotopic niche shifts in stream biota including an endangered rainbow trout ecotype

Autor: Nathan A. Medinski, Bryan M. Maitland, Timothy D. Jardine, D. Andrew R. Drake, Mark S. Poesch

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 79:1321-1334

Freshwater biodiversity is declining from impacts associated with anthropogenic stressors. Here, we use carbon (δ13C) and nitrogen (δ15N) stable isotopes to assess food web effects following a coal mine spill that displaced biota and altered biophy
