The role of behavioural measures in successful fishway passage during seasonal brown trout (Salmo trutta) migration

open access: yesJournal of Fish Biology, EarlyView.
Abstract Successfully overcoming lateral barriers in rivers is crucial for longitudinal fish migration and is influenced mainly by fishway design, environmental variability and/or individual behavioural traits. Although behavioural traits are well studied in many contexts, their role in predicting fishway passage success in the wild remains poorly ...

Quantifying skin microvascular function responses to distinct forms of heat stress in humans using optical coherence tomography

open access: yesExperimental Physiology, EarlyView.
Abstract Optical coherence tomography (OCT) enables visualization and quantification of the cutaneous microvasculature, yet no study has compared responses to distinct forms of heating in humans. We hypothesized that local skin heating (LH) would evoke larger responses in microvascular diameter, velocity, flow and density than passive whole‐body ...

Nocturnal migratory songbirds adjust their travelling direction aloft: evidence from a radiotelemetry and radar study.

open access: yes, 2015
In order to fully understand the orientation behaviour of migrating birds, it is important to understand when birds set their travel direction. Departure directions of migratory passerines leaving stopover sites are often assumed to reflect the birds ...

Direct evidence implicating the asymmetrical dimethylarginine (ADMA)‐dimethylarginine dimethylaminohydrolase 1 (DDAH1) pathway in cerebrovascular dysfunction and stroke pathogenesis in mice

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 21, Page 6422-6443, November 2026.
Abstract Background and Purpose Asymmetrical dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthase (NOS), whereas dimethylaminohydrolase 1 (DDAH1) is primarily responsible for its metabolism. However, the roles of DDAH1 in cerebrovascular regulation are poorly understood. Furthermore, despite evidence that elevated ADMA levels are

Radiotelemetry Of Heart Rates From Free-Ranging Gulls [PDF]

open access: yes, 1978
A lightweight radiotelemetry system with a range of 80 km was used to monitor heart rate from free-ranging Herring Gulls on flights of up to 20 km. Heart rate varied from 130 beats/min in a resting bird to 625 beats/min for sustained flight.

Movements of female exurban white‐tailed deer in response to controlled hunts

open access: yesWildlife Society Bulletin, 2013
White‐tailed deer (Odocoileus virginianus) thrive in exurban habitats, which results in increased occurrences of deer–human conflicts. Controlled hunts are one method currently used by managers to deal with increasing exurban deer populations. To develop

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

open access: yesExperimental Physiology, Volume 111, Issue 11, Page 5094-5104, 1 November 2026.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Can landscape management provide disease regulation services? A case study of Brazilian spotted fever incidence

open access: yesJournal of Applied Ecology, Volume 63, Issue 10, October 2026.
Policy implications. Our results can help prioritize surveillance strategies and the implementation of preventive measures, particularly in areas where landscape structures cannot provide disease regulation services. Landscape management actions aimed at increasing the amount of forest areas in a more aggregated manner could help restore those ...

Integrating telemetry data into spatial capture–recapture modifies inferences on multi‐scale resource selection

open access: yesEcosphere, 2018
Estimating population size and resource selection functions (RSFs) are common approaches in applied ecology for addressing wildlife conservation and management objectives.

A generalized method to determine detectability of rare and cryptic species using the ornate box turtle as a model

open access: yesWildlife Society Bulletin, 2011
Estimates regarding population parameters are often based on data from surveys. To ensure that such estimates are as accurate as possible, it is important to know the detectability resulting from the particular survey method used.
