After All, Size Does Matter: Size and Trachemys Scripta Reproduction Traits at the Western Limit of Its European Distribution

Integrative Zoology, EarlyView.
‐ Female T. scripta exhibit a clear size‐dependent reproductive investment, where larger plastron length is positively associated with all key reproductive traits. ‐ Female T. scripta reach sexual maturity at a plastron length of approximately 15–18 cm. ABSTRACT In invasive species, reproductive success may determine invasion outcomes and influence the

Effect of Morphology and Spatial Distribution of Males on Vocal Identity in a Non‐Learning African Wood Dove

Integrative Zoology, EarlyView.
Emerald‐spotted Wood‐Dove songs show strong individual vocal signatures. Morphology explains little acoustic variation. Acoustic divergence increases with geographic distance between males, while local neighbor density does not influence vocal distinctiveness.

Handling mean–variance scaling in intraspecific trait variability and implications for trait–environment analyses

Methods in Ecology and Evolution, EarlyView.
Abstract Trait‐based ecology increasingly relies on measures of intraspecific trait variability to estimate how trait diversity within species varies across species and environmental gradients. Yet variance and related metrics are often interpreted without considering their intrinsic dependence on the mean, as described by the empirical Taylor's power ...

From LiDAR point clouds to 3D tree morphometrics: New approach to quantitatively evaluate tree shapes

Methods in Ecology and Evolution, EarlyView.
Abstract Tree crowns are complex, three‐dimensional structures whose morphology varies among species, individuals and environments. Although light detection and ranging (LiDAR) provides high‐resolution, single‐tree point clouds that advance species discrimination and the assessment of intraspecific variation in situ, crown shape is still commonly ...

Ground‐penetrating radar amplitudes to roots: A numerical modelling framework for mapping coarse root system architecture

Methods in Ecology and Evolution, EarlyView.
Abstract Observations of three‐dimensional (3D) coarse root system architecture remain limited because most measurement approaches require excavation. Here, we combined dense single‐ and multi‐channel 500 MHz ground‐penetrating radar (GPR) surveys with a flow‐guided connectivity framework to non‐destructively characterise the coarse root architecture ...

Information flow and the adoption of soil‐improving and water conservation measures, and household welfare: Insights from a randomized controlled trial in Uganda

American Journal of Agricultural Economics, EarlyView.
Abstract Extension services are designed to facilitate the flow of information from researchers to farmers. However, information failures continue to impede the diffusion of soil‐improving and water conservation technologies in Sub‐Saharan African countries. We use a randomized controlled trial (RCT) to examine the impact of an extension‐based campaign

Multiscale Modeling of a Geometrically Tunable Shunt for Growing Pediatric Patients With Single Ventricle Physiology

Artificial Organs, EarlyView.
Here we investigated the development of a geometrically tunable blood for patients with single ventricle physiology. Two multiscale cardiovascular models were customized and implemented at timepoints spanning across the beginning and end of the shunt‐use period.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.
