Environmental assessment for the Satellite Power System (SPS): Studies of honey bees exposed to 2.45 GHz continuous wave electromagnetic energy [PDF]

, 1980
Post treatment brood development was normal and teratological effects were not detected at exposures of 3 to 50 mw sq cm for 30 minutes. Post treatment survival, longevity, orientation, navigation, and memory of adult bees were also normal after ...

The High‐Altitude Adaptation Characteristics of Microbiota‐Host Cross‐Talk in Yak Gastrointestinal Track

Advanced Science, EarlyView.
In this study, a single‐cell atlas of 117,019 yak gastrointestinal cells across 54 subtypes identified HNF4A and SREBF2 as key transcription factors targeting MYO6 gene. Cross‐species and multi‐omics analyses reveals epithelial cells as key regulators that, through interactions with microbes, particularly Bacillus, facilitate flexible energy supply and

Leatherback Turtles in the Eastern Gulf of Mexico: Foraging and Migration Behavior During the Autumn and Winter

Frontiers in Marine Science, 2021
We deployed 19 satellite tags on foraging adult leatherback turtles, including 17 females and 2 males, captured in the northeastern Gulf of Mexico in 2015, 2018, and 2019 in order to study regional distribution and movements.

Investigating the impacts of field‐realistic exposure to a neonicotinoid pesticide on bumblebee foraging, homing ability and colony growth

Journal of Applied Ecology, 2016
Summary The ability to forage and return home is essential to the success of bees as both foragers and pollinators. Pesticide exposure may cause behavioural changes that interfere with these processes, with consequences for colony persistence and ...

Medicago Sativa L. Saponin‐Driven Lactobacillus Intestinalis Restores Intestinal Stemness in Naturally Aged Mice via the Bile Acid‐FXR‐Wnt Signaling Axis

Advanced Science, EarlyView.
This study examines the mechanism by which alfalfa saponin (AS) regulates intestinal stemness via modulation of the gut microbiota. The results indicate that AS significantly increases the abundance of Lactobacillus intestinalis, which subsequently activates Wnt signaling via bile acid metabolism and enhances intestinal stemness. These findings provide

The Possible Role of Body Temperature in Modulating Brain and Body Sizes in Hominin Evolution

Frontiers in Psychology, 2022
Many models have posited that the concomitant evolution of large brains and body sizes in hominins was constrained by metabolic costs. In such studies, the impact of body temperature has arguably not been sufficiently addressed despite the well ...

Exploring the evolution of a trade-off between vigilance and foraging in group-living organisms

, 2014
Despite the fact that grouping behavior has been actively studied for over a century, the relative importance of the numerous proposed fitness benefits of grouping remain unclear.

Effects of age and reproductive status on individual foraging site fidelity in a long-lived marine predator

Proceedings of the Royal Society B: Biological Sciences, 2017
Individual foraging specializations, where individuals use a small component of the population niche width, are widespread in nature with important ecological and evolutionary implications.
