Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

Direct Estimation of Forest Aboveground Biomass from UAV LiDAR and RGB Observations in Forest Stands with Various Tree Densities

open access: yesRemote Sensing
Canada’s vast forests play a substantial role in the global carbon balance but require laborious and expensive forest inventory campaigns to monitor changes in aboveground biomass (AGB).

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

open access: yesThe Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Semi-Supervised Multimodal Individual Tree Crown Delineation via Crown Vertical Semantic Distillation With Selective Coupling

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Trees play a pivotal role in industrial processes by providing raw materials, such as timber and paper, while simultaneously contributing to sustainable practices through carbon dioxide sequestration and biodiversity support.

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Property Rights Entrepreneurship: The Drive for Product, Asset, and Resource Excludability

open access: yesManagerial and Decision Economics, EarlyView.
ABSTRACT Property rights are foundational to market economies, and entrepreneurial activity depends heavily on the excludability afforded by property rights. Yet, the role of entrepreneurs in shaping the evolution of property rights has been so thoroughly taken for granted that it often vanishes from analyses.

Do good neighbours compensate for bad climate? The case of sessile oak Quercus petraea in phylogenetically distant neighbourhoods

open access: yesOikos, EarlyView.
Stressful climates threaten the performance of individuals and the survival of species, but individual performance also depends on biotic interactions with neighbours, so that ‘good' neighbours might in theory compensate for ‘bad' climates. However, what makes a good neighbour, and why, has been little studied.

Domain-Aware Transfer Learning With SAM-Assisted Mask R-CNN for Urban Tree Crown Delineation From UAV Orthophotos

open access: yesIEEE Access
Accurate tree crown delineation from very high-resolution UAV orthophotos in urban areas remains challenging due to landscape complexity and the scarcity of representative annotated data.

Integrating vision, audition and olfaction traits: a roadmap for contrasting sensory ecologies of birds and rodents

open access: yesOikos, EarlyView.
Sensory ecology seeks to understand how organisms detect and use information from their environment, yet comparative analyses across multiple sensory modalities remain rare. Here, we present a roadmap for contrasting the sensory ecologies of birds and rodents using surrogate morphological and acoustic traits associated with vision, audition, and ...

Green pathways to mental health: Relationships between treescapes and well‐being and distress

open access: yesPeople and Nature, EarlyView.
Abstract We aimed to evaluate the mental health benefits and possible mechanisms of objective and subjective treescape exposures whilst also accounting for relationships with residential area greenspace in general. Independent variables were objective measures of residential neighbourhood tree cover density and woody linear features, and a subjective ...
