Neighborhood Diversity Promotes Tree Growth in a Secondary Forest: The Interplay of Intraspecific Competition, Interspecific Competition, and Spatial Scale

Plants
Understanding the biodiversity–productivity relationship (BPR) is crucial for biodiversity conservation and ecosystem management. While it is known that diversity enhances forest productivity, the underlying mechanisms at the local neighborhood level ...

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Spatial distribution pattern and negative density dependence analysis of northern subtropical forest communities in Baohua Mountain

Global Ecology and Conservation
Negative density dependence (NDD) serves as a crucial regulatory mechanism for maintaining biodiversity in forest ecosystems. Testing intraspecific and interspecific competition is fundamental for understanding species coexistence.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Toward an Improved Conceptual Understanding of North American Tree Species Distributions

, 2017
Species distributions have often been assumed to represent climatic limitations, yet recent evidence has challenged these assumptions and emphasized the potential importance of biotic interactions, dispersal limitation, and disturbance.

Trophic plasticity and novel predator-prey interaction between two introduced snakes in a Mediterranean island

Acta Herpetologica
We report the first documented case of interspecific ophiophagy by the naturalised false smooth snake (Macroprotodon mauritanicus), observed preying upon the introduced horseshoe whip snake (Hemorrhois hippocrepis) in Mallorca (Balearic Islands, Spain).

Establishment of Interspecies Somatic Cell Nuclear Transfer and Transgene‐Free Inducible Pluripotent Stem Cells for Versatile Conservation of the Germplasm Resource of Wild Boar

Animal Research and One Health, EarlyView.
Conserving genetic material and even increasing genetic diversity is critical. To conduct the conservation of wild boar germplasm resources, we have successfully obtained healthy cloned wild boars for the first time using interspecies somatic cell nuclear transfer and established transgene‐free iPSCs that can be used to conduct iterative rounds of gene

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Spatial Distribution and Intraspecific and Interspecific Associations of Dominant Tree Species in a Deciduous Broad-Leaved Forest in Shennongjia, China

Diversity
Studying spatial distribution patterns and intraspecific and interspecific associations of tree species is crucial for understanding the maintenance of biodiversity and offering insights into community dynamics and stability.
