1. A benign juvenile environment reduces the strength of antagonistic pleiotropy and genetic variation in the rate of senescence

Abstract:
... The environment can play an important role in the evolution of senescence because the optimal allocation between somatic maintenance and reproduction depends on external factors influencing life expectancy. The aims of this study were to experimentally test whether environmental conditions during early life can shape senescence schedules, and if so, to examine whether variation among individuals o ...

Subject:
Autographa gamma; air; autumn; flight; migratory behavior; moths; radar; songbirds; spring; wind speed; Europe
Abstract:
... Animals that use flight as their mode of transportation must cope with the fact that their migration and orientation performance is strongly affected by the flow of the medium they are moving in, that is by the winds. Different strategies can be used to mitigate the negative effects and benefit from the positive effects of a moving flow. The strategies an animal can use will be constrained by the ...

Abstract:
... A thorough understanding of mechanisms of prey consumption by carnivores and the constraints on predation help us in evaluating the role of carnivores in an ecosystem. This is crucial in developing appropriate management strategies for their conservation and mitigating human–carnivore conflict. Current models on optimal foraging suggest that mammalian carnivores would profit most from killing the ...

Abstract:
... Understanding how individual movement scales with body size is of fundamental importance in predicting ecological relationships for diverse species. One‐dimensional movement metrics scale consistently with body size yet vary over different temporal scales. Knowing how temporal scale influences the relationship between animal body size and movement would better inform hypotheses about the efficienc ...

Abstract:
... Predators affect prey populations not only through direct predation, but also by acting as definitive hosts for their parasites and completing parasite life cycles. Understanding the affects of parasitism on prey population dynamics requires knowing how their predators’ parasite community is affected by diet and prey availability. Ungulates, such as moose (Alces americanus) and white‐tailed deer ( ...

Abstract:
... Despite the capacity of invasive alien species to alter ecosystems, the mechanisms underlying their impact remain only partly understood. Invasive alien predators, for example, can significantly disrupt recipient communities by consuming prey species or acting as an intraguild predator (IGP). Behavioural interactions are key components of interspecific competition between predators, yet these are ...

Abstract:
... Understanding interspecific interactions, and the influences of anthropogenic disturbance and environmental change on communities, are key challenges in ecology. Despite the pressing need to understand these fundamental drivers of community structure and dynamics, only 17% of ecological studies conducted over the past three decades have been at the community level. Here, we assess the trophic stru ...

Abstract:
... Spatial resource subsidies can alter bottom‐up and top‐down forces of community regulation across ecosystem boundaries. Most subsidies are temporally variable, and recent theory has suggested that consumer‐resource dynamics can be stabilized if the peak timing of a subsidy is desynchronized with that of prey productivity in the recipient ecosystem. However, magnitude of consumer responses per se c ...

Abstract:
... Variation within species is an often‐overlooked aspect of community ecology, despite the fact that the ontogenetic structure of populations influences processes right up to the ecosystem level. Accounting for traits at the individual level is an important advance in the implementation of trait‐based approaches in understanding community structure and function. We incorporate individual‐ and specie ...

Abstract:
... Migratory animals are predicted to enhance lifetime fitness by obtaining higher quality forage and/or reducing predation risk compared to non‐migratory conspecifics. Despite evidence for behavioural flexibility in other taxa, previous research on large mammals has often assumed that migratory behaviour is a fixed behavioural trait. Migratory behaviour may be plastic for many species, although few ...

Abstract:
... A major challenge in evolutionary ecology is to understand how co‐evolutionary processes shape patterns of interactions between species at community level. Pollination of flowers with long corolla tubes by long‐tongued hawkmoths has been invoked as a showcase model of co‐evolution. Recently, optimal foraging models have predicted that there might be a close association between mouthparts' length a ...

Abstract:
... Long‐lived migratory animals must balance the cost of current reproduction with their own condition ahead of a challenging migration and future reproduction. In these species, carry‐over effects, which occur when events in one season affect the outcome of the subsequent season, may be particularly exacerbated. However, how carry‐over effects influence future breeding outcomes and whether (and how) ...

Many organisms undertake migrations between foraging and breeding habitats and while it is assumed that reproductive timing affects fitness, little is known about the degree of individual consistency, and about the causes and consequences of individual variation in migratory timing in organisms other than birds.

Abstract:
... Male‐biased sex ratios occur in many bird species, particularly in those with small or declining populations, but the causes of these skews and their consequences for local population demography are rarely known. Within‐species variation in sex ratios can help to identify the demographic and behavioural processes associated with such biases. Small populations may be more likely to have skewed sex ...

Abstract:
... In seasonal climates, dormancy is a common strategy that structures biodiversity and is necessary for the persistence of many species. Climate change will likely alter dormancy dynamics in zooplankton, the basis of aquatic food webs, by altering two important hatching cues: mean temperatures during the ice‐free season, and mean day length when lakes become ice free. Theory suggests that these chan ...

Abstract:
... Substantial plastic variation in phenology in response to environmental heterogeneity through time in the same population has been uncovered in many species. However, our understanding of differences in reaction norms of phenology among populations from a given species remains limited. As the plasticity of phenological traits is often influenced by local thermal conditions, we expect local tempera ...

Abstract:
... Experimental work increasingly suggests that non‐random pathogen associations can affect the spread or severity of disease. Yet due to difficulties distinguishing and interpreting co‐infections, evidence for the presence and directionality of pathogen co‐occurrences in wildlife is rudimentary. We provide empirical evidence for pathogen co‐occurrences by analysing infection matrices for avian malar ...

Animals with lethal infections are faced with a difficult choice: to allocate more resources to reproduction and suffer higher mortality or to reduce reproduction with the expectation of enhanced immunity and late‐age reproduction. However, the strategies employed to media ...

This leads to the formation of numerous new periglacial ponds and lakes, which are being colonized by planktonic organisms such as the water flea Daphnia. This system provides unique opportunities to test genotype colonization dynamics and the genetic assemblage of populations. Here, we studied clonal richness of the Daphnia pulex species co ...
