A Food Web Model of the Serengeti: Stability, Dynamics and Indirect Effects
ABSTRACT Effective conservation management of a complex ecosystem like the Serengeti can benefit from a systems‐wide approach to interactions between functional groups. This study presents a food web model of the Serengeti based on generalised Lotka–Volterra equations parameterised using data from the literature. The internal equilibrium point is shown

The argali (Ovis ammon antiqua) from the Magliana area (Rome) [PDF]
During the Middle Pleistocene, the subspecies was widespread from Georgia to Portugal, though it is scantily recorded in local faunal assemblages of Southern Europe. Its occurrence in a few Late Pleistocene sites needs to be confirmed.

Abstract Background Synovial fluid (SF) is an ideal sentinel fluid for osteoarthritis (OA) diagnosis and prognostication due to its critical homeostatic role, proximity to articular tissues and immune cell composition. Untargeted proteomics enable identification of soluble markers for diagnostic and therapeutic applications while minimising bias ...

ABSTRACT Aim Large herbivores play key roles in ecosystems by promoting plant diversity, dispersing seeds, regulating nutrient cycling, and shaping vegetation structure. Since the Late Pleistocene, their declines have led to profound ecosystem changes. While often viewed as problematic, alien herbivores may partly compensate for these losses; yet their
