Feeding and foraging ecology of Trindade petrels Pterodroma arminjoniana during the breeding period in the South Atlantic Ocean [PDF]
, 2017 Seabirds breeding in tropical environments experience high energetic demands, when foraging in an oligotrophic environment. The globally threatened Trindade petrel Pterodroma arminjoniana has its largest colony in Trindade Island (20°30′S–29°19′W) inside

Isotopic niches reveal the impact of topmouth gudgeon and gibel carp on native crucian carp [PDF]
NeoBiotaInvasive species pose a major threat to natural ecosystems and directly outcompete many native species, placing them at imminent threat of extinction. The topmouth gudgeon (Pseudorasbora parva) is on the EU’s blacklist of invasive freshwater species and ...

Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]
, 2016 Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...

Comparing isotopic niche widths among and within communities: SIBER - Stable Isotope Bayesian Ellipses in R. [PDF]
The Journal of animal ecology, 2011 1. The use of stable isotope data to infer characteristics of community structure and niche width of community members has become increasingly common. Although these developments have provided ecologists with new perspectives, their full impact has been hampered by an inability to statistically compare individual communities using descriptive metrics ...

Reframing the mammoth steppe: Insights from analysis of isotopic niches [PDF]
Quaternary Science Reviews, 2019 Woolly mammoth (Mammuthus primigenius), horse (Equus spp.) and bison (Bison spp.) coexisted with a variety of mammalian megafauna across the Pleistocene mammoth steppe – a megacontinental ecosystem that spanned northern Eurasia and northwestern North America.

Angewandte Chemie, EarlyView.A large variety of chemistry‐based ubiquitin probes have been developed. ABSTRACT Ubiquitin (Ub) and ubiquitin‐like proteins (Ubls) orchestrate diverse cellular processes through reversible post‐translational modification of target proteins. Their conjugation is governed by a cascade of E1 activating, E2 conjugating, and E3 ligating enzymes, while ...

Do trophic subsidies affect the outcome of introductions of a non-native freshwater fish? [PDF]
, 2013 Understanding how environmental variables and human disturbances influence the outcomes of introductions of non-native freshwater fish is integral to their risk management. This can be complex in freshwater ecosystems that receive subsidies that increase
