Better to risk limb than life: some insects use autotomy to escape passive predation by carnivorous plantsNARA Subscribed
Limb autotomy, the voluntary shedding of body parts as a strategy to escape predation or entrapment, is particularly common in insects and other arthropods that are frequently captured by the carnivorous plant genus Drosera . However, no study has previously examined the effectiveness of autotomy at facilitating escape from these passive, sessile plant predators. Using field observations of numerous Drosera species in Western...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Mitigation translocation as a management toolNARA Subscribed
Mitigation translocation is a subgroup of conservation translocation, categorized by a crisis‐responsive time frame and the immediate goal of relocating individuals threatened with death. However, the relative successes of conservation translocations with longer time frames and broader metapopulation‐ and ecosystem‐level considerations have been used to justify the continued implementation of mitigation translocations without...
Body size and digestive system shape resource selection by ungulates: A cross‐taxa test of the forage maturation hypothesisNARA Subscribed
The forage maturation hypothesis (FMH) states that energy intake for ungulates is maximised when forage biomass is at intermediate levels. Nevertheless, metabolic allometry and different digestive systems suggest that resource selection should vary across ungulate species. By combining GPS relocations with remotely sensed data on forage characteristics and surface water, we quantified the effect of body size and digestive syst...
Animals can be important in modulating ecosystem‐level nutrient cycling, although their importance varies greatly among species and ecosystems. Nutrient cycling rates of individual animals represent valuable data for testing the predictions of important frameworks such as the Metabolic Theory of Ecology ( MTE ) and ecological stoichiometry ( ES ). They also represent an important set of functional traits that may reflect both...
Inferring infection hazard in wildlife populations by linking data across individual and population scalesNARA Subscribed
Our ability to infer unobservable disease‐dynamic processes such as force of infection (infection hazard for susceptible hosts) has transformed our understanding of disease transmission mechanisms and capacity to predict disease dynamics. Conventional methods for inferring FOI estimate a time‐averaged value and are based on population‐level processes. Because many pathogens exhibit epidemic cycling and FOI is the result of pro...
