Ecological and genetic effects of introduced species on their native competitors

, 2013
Species introductions to new habitats can cause a decline in the population size of competing native species and consequently also in their genetic diversity.

Functional Stability Despite Taxonomic Changes in Mixed‐Species Foraging Flock Participants Along an Elevational Gradient in Knuckles Montane Reserve, Sri Lanka 斯里兰卡纳克斯山地保护区 (Knuckles Montane Reserve) 海拔梯度上混合物种觅食群参与者的功能稳定性与分类变化

Integrative Conservation, EarlyView.
This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Mulching Increases Water Use Efficiency, Production and Profitability in Forage Cactus–Maize Intercropping Systems

Irrigation and Drainage, EarlyView.
ABSTRACT This study evaluated the growth, forage production, soil water balance, water indices, biological efficiency and competitive capacity of forage cactus and maize in monoculture and intercropping, with or without mulch. The experiment was conducted in Serra Talhada, Pernambuco, Brazil, using the cactus clone ‘Orelha de Elefante Mexicana’ (OEM ...

Two Problems for the Political Inclusion of Animals

Journal of Applied Philosophy, EarlyView.
ABSTRACT In recent years, the field of animal ethics has taken a political turn, with scholars arguing that sentient nonhuman animals should be included in the political sphere. This article explores two key challenges arising from this turn towards the political inclusion of animals: the Conflict Problem and the Numbers Problem.

Spatial Overlap and Behavioral Interactions Among Four Habronattus Jumping Spider Species in a Mixed‐Species Assemblage

Ecology and Evolution
Within mixed‐species assemblages, closely related species may face interspecific competition and reproductive interference. Species may evolve adaptations to outcompete or coexist, though most assemblages likely exist in a nonequilibrium state between ...

Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

Journal of Applied Toxicology, EarlyView.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Joint Angular Excursions and Angular Range Utilization During Stance‐Phase Locomotion in Terrestrial Mammals: A Comparative Morphofunctional Data Set

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
This study quantifies stance‐phase joint angular excursions and angular utilization (AUI%) during walking in 182 terrestrial mammal species. Across mammals, total limb excursion during stance (TAE) decreases with increasing body mass, whereas AUI% remains broadly conserved, indicating similar proportional use of summed joint excursions to generate net ...

The use of edible insects in human food

Journal of the Science of Food and Agriculture, EarlyView.
Abstract The world population is expected to reach approximately 10 billion people by 2050, which will significantly increase global food demand and may lead to agricultural shortages and a higher risk of food insecurity. In this context, this review discusses the potential of insects as alternative sources of animal protein, addressing their ...
