Epigenetic Dysregulation of the NKX2‐1/SPDEF Axis Drives Persistent Goblet Cell Differentiation and Epithelial Barrier Dysfunction in Chronic Obstructive Pulmonary Disease

Respirology, EarlyView.
This study investigated airway epithelial barrier dysfunction persistence in ex‐smokers with COPD and underlying mechanisms using single‐cell RNA and ATAC sequencing. Epigenetic NKX2‐1/SPDEF dysregulation maintains goblet cell hyperplasia and barrier dysfunction despite long‐term smoking cessation.

Tourist sightings improve the precision of camera trap‐derived density estimates using spatial capture‐recapture models

Remote Sensing in Ecology and Conservation, EarlyView.
In this study, we combine tourist‐contributed images with camera trap‐based monitoring data to estimate leopard (Panthera pardus) population densities using multi‐session spatial capture–recapture models. We show that incorporating tourist observations improves precision and yields an overall density estimate of 7.02 leopards per 100 km2, while ...

Human Center of Gravity Dynamics a New Parameter of Motor Development Functions [PDF]

, 2001
A study of a new parameter of human growth and development was conducted. The percentage of the height of body gravity center to the stature in supine position was measured in males and females during the period of pre-puberty (l995), young and adult ...

Can Sustainable Development Goal Classification Tools Be Trusted? Analysing the Spanish National Research Council Output on Gender Equality

Sustainable Development, EarlyView.
ABSTRACT Evaluating research contributions to the Sustainable Development Goals (SDGs) remains challenging, particularly for SDG 5 (Gender Equality), which is cross‐cutting, thematically complex and apparently underrepresented in scientific output. This study evaluates the abilities and limitations of automated classification systems (Web of Science ...

Beyond abundance: the impact of sampling design on effective population size estimates in capercaillie

Wildlife Biology, EarlyView.
Effective population size (Ne) is a useful parameter to evaluate the long‐term viability of populations. While obtaining enough field data from wild populations to estimate Ne directly is challenging, molecular techniques applied to non‐invasive samples provide an appealing alternative.

Evaluating machine learning models for multi‐species wildlife detection and identification on remote sensed nadir imagery in South African savanna

Wildlife Biology, EarlyView.
This research paper investigates the efficacy of leading machine learning (ML) models for detecting and identifying ungulate species in African savanna using nadir imagery from unmanned aerial vehicles (UAVs). Traditional aerial counting methods, while widely used, suffer from significant limitations in accuracy and precision, in part due to human ...

Tradeoffs between brain and digestive tissues across elevations in Typhlomys daloushanensis: evidence for sexual dimorphism

Wildlife Biology, EarlyView.
To cope with highly stochastic and/or heterogeneous environmental conditions, animals must balance energy resource allocation across physiological processes. The digestive tract and brain exhibit structural variations under strong developmental and selective pressures that vary across environmental gradients both between and within species.

Development of Microsatellite Markers for Ex Situ Management of the Harpy Eagle Using Next Generation Sequencing

Zoo Biology, EarlyView.
ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

Changing food availability and its effect on the heritability of offspring size in woodland passerine birds

Journal of Animal Ecology, EarlyView.
Vatka et al. investigated how changing food abundance affects evolutionary potential of offsprings' body size traits in two woodland passerines. Food availability increased over the 25‐year‐long study period, accompanied by increases in body mass.

Global determinants of home range sizes in felids: Evidence of human disturbance impact

Journal of Animal Ecology, EarlyView.
This study is the first to demonstrate the influence of anthropogenic factors and species richness in felids on home range size across the entire felid taxon. Felids are a taxon of major interest in conservation biology, and gaining a comprehensive view of their spatial ecology will help derive global conservation recommendations.
