Predator-Induced Changes in Metabolism Cannot Explain the Growth/Predation Risk Tradeoff

open access: yesPLoS ONE, 2009
Defence against predators is usually accompanied by declining rates of growth or development. The classical growth/predation risk tradeoff assumes reduced activity as the cause of these declines. However, in many cases these costs cannot be explained by reduced foraging effort or enhanced allocation to defensive structures under predation risk.

Reintroducing the dingo: the risk of dingo predation to threatened vertebrates of western New South Wales

open access: yes, 2012
Context. The reintroduction of dingoes into sheep-grazing areas south-east of the dingo barrier fence has been suggested as a mechanism to suppress fox and feral-cat impacts.

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

open access: yesThe Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

Manipulating individual decisions and environmental conditions reveal individual quality in decision-making and non-lethal costs of predation risk.

open access: yesPLoS ONE, 2012
Habitat selection is a crucial decision for any organism. Selecting a high quality site will positively impact survival and reproductive output. Predation risk is an important component of habitat quality that is known to impact reproductive success and ...

Sport, Agency and Pigeon Snaring in the Ancient Tongan Chiefdom

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Pigeon snaring was an élite sport in the traditional Tongan chiefdom, undertaken on purpose‐built mounds known as sia heu lupe. LiDAR imagery combined with field survey and mound documentation on the island of Tongatapu has identified a comprehensive corpus of these sites.

Spatial and temporal patterns of carabid activity-density in cereals do not explain levels of predation on weed seeds [PDF]

open access: yes, 2008
Seed predation is an important component of seed mortality of weeds in agro-ecosystems, but the agronomic use and management of this natural weed suppression is hampered by a lack of insight in the underlying ecological processes.

Autoantibodies to Joint‐Related Peptides Are Associated With Onset of Rheumatoid Arthritis in Presymptomatic Seronegative Individuals

open access: yesArthritis &Rheumatology, EarlyView.
Objective To identify autoantibodies in presymptomatic individuals that associate with the onset of rheumatoid arthritis (RA) and to distinguish early RA from osteoarthritis (OA), particularly in individuals lacking classic RA serologic markers. Methods We analyzed serum and plasma from three cohorts: presymptomatic individuals who later developed RA ...

Cancer in Systemic Sclerosis: Clinical Associations and Prognostic Impact From the EUSTAR Registry

open access: yesArthritis &Rheumatology, EarlyView.
Objective Cancer represents a major cause of death in systemic sclerosis (SSc). Established risk factors are limited to specific subsets, particularly early diffuse anti‐RNA polymerase III (POLR3)–positive disease, needing further exploration. Methods We performed a nested case‐control study within the European Scleroderma Trials and Research group ...

Fish predation on a landscape scale

open access: yesEcosphere, 2020
Predator–prey dynamics can have landscape‐level impacts on ecosystems, and yet, spatial patterns and environmental predictors of predator–prey dynamics are often investigated at discrete locations, limiting our understanding of the broader impacts.
