Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group‐level processes such as subgroup formation and fission–fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing coh...
High‐resolution data are necessary to understand the effects of climate on plant population dynamics of a forest herbNARA Subscribed
Climate is assumed to strongly influence species distribution and abundance. Although the performance of many organisms is influenced by the climate in their immediate proximity, the climate data used to model their distributions often have a coarse spatial resolution. This is problematic because the local climate experienced by individuals might deviate substantially from the regional average. This problem is likely to be par...
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...
Remediation of upstream passage for migrating Galaxias (Family: Galaxiidae) through a pipe culvertNARA Subscribed
Movement through streams is critical for the maintenance of diadromous fish populations. Numerous fish passage improvement techniques exist, and knowledge of their effectiveness is required to conserve target species. An existing 70‐m pipe culvert was considered a barrier to the passage success of young‐of‐year (YOY) Galaxias spp. as a result of high water velocity (0.9 m/s). Water velocity in the pipe culvert was reduced by i...
Sex‐specific distribution and diet of Platichthys flesus at the end of spawning in the northern Baltic SeaNARA Subscribed
This study examined the relationship of seascape structure, prey availability and sex on the post‐spawning distribution and diet of European flounder Platichthys flesus in the northern Baltic Sea. The objectives were to determine whether: (1) wave exposure and substratum affect abundance and distribution of P. flesus , (2) diet reflects the benthic prey composition and (3) sex affects the distribution or diet of P. flesus . Th...
Changes in reproductive physiology and behaviour over the nesting cycle in male three‐spined sticklebacksNARA Subscribed
Plasma 11‐Ketotestosterone (11 KT) and testosterone (T) levels and spiggin‐mRNA levels, as well as the kidney‐somatic index ( I K ) were measured in sexual males and in paternal males at the middle (5 days paternal) and at the end (8 days paternal with hatched eggs) of the nesting cycle in three‐spined sticklebacks Gasterosteus aculeatus from two populations. Glueing (using threads of 11 KT induced kidney‐protein spiggin) and...
