Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Efecto de la concentración de ivermectina sobre el control de parásitos internos y el desempeño productivo de bovinos / Effect of ivermectin concentration on internal parasite control and the productive performance of bovine

Ciencia Veterinaria, 2017
El objetivo del presente trabajo fue evaluar la eficacia del tratamiento con dosis crecientes de ivermectina sobre la carga parasitaria expresada en el número de huevos por heces y la incidencia sobre la ganancia de peso de vaquillas de sobreaño en un ...

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Evaluación biológica de la gobernadora (Larrea tridentata) con animales de laboratorio

Revista Mexicana de Ciencias Pecuarias
Se estudió el valor nutritivo de la gobernadora (Larrea tridentata) en animales de laboratorio. Se condujeron 3 experimentos utilizando ratones albinos (CH3) y ratas (Wistar). Se probaron raciones con gobernadora sin extraer y extraída con agua. Como fuente de líquidos se aprobó una difusión de gobernadora o agua. Se ensayaron métodos para desintoxicar

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Optimising daily sampling of plant–bee interaction networks

Journal of Animal Ecology, EarlyView.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...

Relationship between spatial and social phenotypes in an avian scavenger

Journal of Animal Ecology, EarlyView.
A method is applied to distinguish interaction rates that would be expected given animals' movements from those that exceed expected values due to incidental contact. The relationship between space use and both observed and non‐incidental social network position varies between social situations.
