De novo origins of multicellularity in response to predation

open access: yesScientific Reports, 2018
The transition from unicellular to multicellular life was one of a few major events in the history of life that created new opportunities for more complex biological systems to evolve.

Rat snakes, cowbirds, and vines lower passerine nest survival in remnant bottomland hardwood forests in east-central Arkansas, USA

open access: yesAvian Conservation and Ecology, 2021
Predation is often the leading cause of nest failure among passerines; however, specific causes are often unknown or can be misidentified in the field.

Predation domes: In‐situ field assays to measure predatory behaviours by fish

open access: yesMethods in Ecology and Evolution, 2023
Biotic interactions such as predation are difficult ecological processes to quantify in the wild. This is especially the case in the marine environment due to logistical difficulties in capturing animal behaviour.

UNSUCCESSFUL PREDATION AND LEARNING OF PREDATOR CUES BY CRAYFISH [PDF]

open access: yesJournal of Crustacean Biology, 2003
Abstract The effect of latent inhibition on learning about cues related to increased predation risk was studied in a native crayfish, Orconectes virilis, and in an invasive species, Orconectes rusticus. Individuals of both species either were exposed or not exposed to the conditioned stimulus (potential “predator” odor = goldfish odor) prior to ...

Nest Predation Pressure Differs Between Urban Ground- and Hole-Nesting Birds: Evidence from a Multi-Year Artificial Nest Predation Experiment

open access: yesBirds
Urbanization changes the environment through physical constructions, disturbances, and altered resource availability. These modifications influence both prey and predator assemblages.

Global pattern of nest predation is disrupted by climate change in shorebirds

open access: yesScience, 2018
No longer a safe haven Many biological patterns have a latitudinal component. One long-recognized pattern is that predation rates are higher at lower latitudes.

Species‐ and origin‐specific susceptibility to bird predation among juvenile salmonids

open access: yesEcosphere, 2023
Juvenile salmonids often experience high mortality rates during migration and bird predation is a common source of mortality. Research suggests that hatchery‐reared salmonids are more prone to predation than wild salmonids, and that Atlantic salmon ...

Maternal predator‐exposure affects offspring size at birth but not telomere length in a live‐bearing fish

open access: yesEcology and Evolution, 2020
The perception of predation risk could affect prey phenotype both within and between generations (via parental effects). The response to predation risk could involve modifications in physiology, morphology, and behavior and can ultimately affect long ...

Assessment of Pain Types in Recently Diagnosed Patients With Inflammatory Arthritis

open access: yesArthritis Care &Research, EarlyView.
Objective Up to 40% of patients with inflammatory arthritis (IA) experience persistent pain, traditionally thought to be associated with a shift from peripherally to centrally mediated pain during the disease course in some patients. We assessed sensory profiles of recently diagnosed individuals with IA, hypothesizing that pain reported at this early ...

Predation of eggs and incubating females in willow ptarmigan Lagopus l. lagopus

open access: yesFauna Norvegica
Nest predation is a major cause of reproductive loss in many ground-nesting birds. During 15 consecutive years the predation of nests and females throughout the incubation season were recorded in a willow ptarmigan Lagopus l.
