Abstract Comparative analyses of survival senescence by using life tables have identified generalizations including the observation that mammals senesce faster than similar‐sized birds. These been challenged because limitations life‐table approaches and growing appreciation is more an increasing probability death. Without tables, we examine rates in annual individual fitness 20 individual‐based data sets terrestrial vertebrates with contrasting histories body size. We find widespread wild...
A major question in ecology is how age-specific variation demographic parameters influences population dynamics. Based on long-term studies of growing populations birds and mammals, we analyze dynamics by using fluctuations the total reproductive value population. This enables us to account for random age distribution. The influence environmental stochasticity a species decreased with generation time. Variation contributions stochastic components was correlated position along slow-fast...
ABSTRACT Aim To identify the broad‐scale oceanic migration routes (‘marine flyways’) used by multiple pelagic, long‐distance migratory seabirds based on a global compilation of tracking data. Location Global. Time Period 1989–2023. Major Taxa Studied Seabirds (Families: Phaethontidae, Hydrobatidae, Diomedeidae, Procellariidae, Laridae and Stercorariidae). Methods We collated comprehensive dataset that included 48 pelagic migrating seabird species across Atlantic, Indian, Pacific Southern...

This paper aims to contribute the ongoing conceptual development and practical pursuit of resilience, ability absorb respond shocks, in an agricultural climate change context. It builds on work that dissolve nature-society dualism naturalisation power relations inherent systems thinking by developing extending a framework originally conceived integrate research biological cultural diversity.

How to best track species as they rapidly alter their distributions in response climate change has become a key scientific priority. Information on is derived from biological records, which tend be primarily sourced traditional recording schemes, but increasingly also by citizen science initiatives and social media platforms, with having more accessible the general public. To date, however, our understanding of respective potential complement information gathered schemes remains limited,...
Abstract Aim Species are largely thought to maintain broadly static niches over time, an assumption underpinning much theoretical ecology including the implementation of ecological models project species' current and future distributions. Here, we assess niche conservatism in odonates Great Britain past six decades by simultaneously quantifying changes species geographic distribution evaluating temporal trends realised climatic niche.

In migratory species, the extent of within- and between-individual variation in strategies can influence potential rates directions responses to environmental changes. Quantifying this requires tracking many individuals on repeated journeys. At temperate higher latitudes, low levels within-individual behaviours are common may reflect use predictable resources these seasonally-structured environments. However, tropics, where seasonal predictability food be weaker, remains largely...
Summary Restoration and maintenance of habitat diversity have been suggested as conservation priorities in farmed landscapes, but how this should be achieved at what scale are unclear. This study makes a novel comparison the effectiveness three wildlife‐friendly farming schemes for supporting local species richness on 12 farms England. The were: (i) Conservation Grade ( : prescriptive, non‐organic, biodiversity‐focused scheme), (ii) organic agriculture (iii) baseline Entry Level Stewardship...

First, how from cash crops is linked with poverty. Second, land are disaggregated. then draws on qualitative data critically reflect understood within studied...

Abstract Globally, pesticides improve crop yields but at great environmental cost, and their overuse has caused resistance. This incurs large financial production losses but, despite this, very diversified farm management that might delay or prevent resistance is uncommon in intensive farming. We asked farmers to design more cropping strategies aimed controlling herbicide resistance, estimated resulting weed densities, profits, compared prevailing practice. Where low, it financially viable...
Abstract Tropical cyclones are renowned for their destructive nature and an important feature of marine coastal tropical ecosystems. Over the last 40 years, intensity, frequency tracks have changed, partly in response to ocean warming, future predictions indicate that these trends likely continue with potential consequences human populations However, our understanding how currently affect biodiversity, pelagic species particular, is limited. For seabirds, impacts known be detrimental at...
