Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah

Journal of Animal Ecology, EarlyView.
For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

Can Fecal T3 Metabolite Level Fluctuations in European Roe Deer (Capreolus capreolus) Give Insights on Body Condition and Thermal Stress?

Integrative Zoology, EarlyView.
European roe deer fecal samples were assayed to investigate the potential fluctuations of fecal thyroid hormone metabolites (FTMs) in response to environmental (e.g., the temperature, local densities) and individual (e.g., sex, age, body, and nutritional conditions) variables.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

Grassland Science, EarlyView.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

Cytoarchitecture and myeloarchitecture of the sheep auditory cortex

Journal of Anatomy, EarlyView.
This article describes the cyto‐ and myeloarchitecture of the sheep auditory cortex. It outlines a six‐layered cortical organization, with variations in cellular types and densities. The potential location of the primary auditory cortex is indicated by parvalbumin immunostaining.
