PREDATION ON SNAKES BY THE FRESHWATER LAND CRAB EUDANIELA GARMANI [PDF]

Journal of Crustacean Biology, 2003
Abstract We recorded the incidence of predation on snakes by the amphibious freshwater land crab Eudaniela garmani (manicou crab) in the rainforests of the Caribbean island of Tobago during 168 days of field observation (spanning a 4-year period) conducted between the hours of 08.00 AM and 12.00 noon and 21.00 PM and 23.30 PM.

Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

Trait compensation in marine gastropods: shell shape, avoidance behavior, and susceptibility to predation [PDF]

, 2004
Many organisms have evolved morphological and behavioral traits that reduce their susceptibility to predation. However, few studies have explicitly investigated the relationships between defensive traits and susceptibility. Here we demonstrate a negative

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Hotter, faster, sicker? Warming shifts the cost of infection from individuals to populations

Journal of Animal Ecology, EarlyView.
This study examines how temperature alters disease impacts across biological scales in a host–pathogen system. We found infected hosts appear healthiest at warm temperatures, yet populations suffer most. This suggests climate warming may intensify disease impacts for populations in ways traditional individual‐level virulence metrics fail to predict ...
