Tadpole body size and behaviour alter the social acquisition of a defensive bacterial symbiont [PDF]
Royal Society Open Science, 2019 Individual differences in host phenotypes can generate heterogeneity in the acquisition and transmission of microbes. Although this has become a prominent factor of disease epidemiology, host phenotypic variation might similarly underlie the transmission

Adaptive Emergence Patterns of Spot-Tailed Earless Lizards: Influence of UV Light and Temperature on Diel Activity. [PDF]
Ecol EvolOur results of spot‐tailed earless lizards (STEL) light‐dependent emergence behavior not only illustrate adaptation to specific environmental cues, but also offer insights into the resilience and adaptability of reptiles inhabiting arid and semiarid ecosystems.

Interaction between feeding rate and area for periphyton in culture of Nile tilapia juveniles =Interação entre a taxa de arraçoamento e a área para perifíton no cultivo de juvenis de tilápia do Nilo [PDF]
Acta Scientiarum: Animal Sciences, 2012 The objective of the present work was to determine the effects of the interaction between feeding rate and area for periphyton in rearing aquaria for Nile tilapia. Twenty 25 L polyethylene outdoor aquaria were used to hold experimental fish.

Flow Structure and Transport Characteristics of Feeding and Exchange Currents Generated by Upside-Down Cassiopea Jellyfish [PDF]
, 2012 Quantifying the flows generated by the pulsations of jellyfish bells is crucial for understanding the mechanics and efficiency of their swimming and feeding. Recent experimental and theoretical work has focused on the dynamics of vortices in the wakes of

Journal of Fish Diseases, EarlyView., 2023 Abstract Bacterial coldwater disease (BCWD), caused by Flavobacterium psychrophilum, results in significant losses among multiple salmonid (family Salmonidae) species. Molecular epidemiology and serotyping studies have suggested that some variants are host specific; however, these associations have not been evaluated by cross‐challenging fish species ...
