TLDR
Although steelhead contribute relatively less to overall modern gull diet, increasing gull populations and simultaneous steelhead population decline likely results in increased per capita predation risk to modern steelhead populations—the best estimate is that modern predationrisk is ~ 2.4 times higher than historically, but this estimate depends on parameter values and overlaps with zero.About:

The Effects of Food Waste on Wildlife and Humans
TL;DR: In this article, the authors highlight the extent of such impacts, drawing on examples from mammalian predators and other taxonomic groups, and show how wildlife access to food waste can exacerbate human-wildlife conflicts.
Journal ArticleDOI
Shifting individual habitat specialization of a successful predator living in anthropogenic landscapes
TL;DR: Investigating the spatial ecology of the opportunistic yellow-legged gull Larus michahellis found that the combination of individual specialization and individual spatial segregation may reduce intra-specific competition, with these 2 important mechanisms driving the success of this winning species.
Journal ArticleDOI
Feathered Detectives: real-time GPS tracking of scavenging gulls pinpoints illegal waste dumping
TL;DR: The potential of novel real-time GPS tracking of scavenging species to detect environmental crime is demonstrated and multi-species guilds of feathered detectives equipped with GPS and cameras could help fight illegal dumping at continental scales.

TL;DR: Rec reconstructed the first long-term spatiotemporal trends of perfluoroalkyl substances (PFAS) using archived body feathers of white-tailed eagles from the West Greenland, Norwegian, and Central Swedish Baltic coasts to suggest on-going input of PFOS in the Baltic and of ∑PFCAs in all three regions.

Inference from Iterative Simulation Using Multiple Sequences
Andrew Gelman,Donald B. Rubin +1 more
TL;DR: The focus is on applied inference for Bayesian posterior distributions in real problems, which often tend toward normal- ity after transformations and marginalization, and the results are derived as normal-theory approximations to exact Bayesian inference, conditional on the observed simulations.

TL;DR: Paleoecological, archaeological, and historical data show that time lags of decades to centuries occurred between the onset of overfishing and consequent changes in ecological communities, because unfished species of similar trophic level assumed the ecological roles of over-fished species until they too were overfished or died of epidemic diseases related to overcrowding as mentioned in this paper.

Fishing Down Marine Food Webs
TL;DR: The mean trophic level of the species groups reported in Food and Agricultural Organization global fisheries statistics declined from 1950 to 1994, and results indicate that present exploitation patterns are unsustainable.

Catastrophes, phase shifts, and large-scale degradation of a Caribbean coral reef.
TL;DR: A dramatic phase shift has occurred in Jamaica, producing a system dominated by fleshy macroalgae (more than 90 percent cover), and immediate implementation of management procedures is necessary to avoid further catastrophic damage.
