Generalized Mechanism Model for Ecosystem Hysteresis
Advanced Science, EarlyView.A simplified model examines ecosystem transitions into alternative states after disturbances by leveraging positive and negative feedbacks. It identifies critical tipping points and quantifies hysteresis. Tests conducted on lakes, grasslands, and pitcher‐plant leaves align closely with empirical data and enable the prediction of recovery trajectories ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
The Anatomical Record, EarlyView.Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

, 2023 The spatial and temporal variation of the zooplankton was studied over an annual cycle at three collection points along the reservoir in the fluvial, transition and lacustrine regions. Altogether, 63 zooplankton species were identified, with 40 Rotifera, 15 Cladocera, and eight Copepoda. Among the Rotifera, 23 species were considered to be rare (< 25%),
