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

open access: yesAdvanced 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

Reduced parental brood visit rate in wild zebra finches Taeniopygia castanotis is correlated with high maximum daily ambient temperature

open access: yesJournal of Avian Biology
As a result of a warming global climate, understanding how organisms adjust their behaviour to environmental thermal conditions has become an increasingly important question in animal biology.

Conserved Forage

open access: yes, 2016
This chapter focuses on conserving forage as hay or silage. Conserving forage is an essential component of ruminant livestock production systems in most temperate climates, but in subtropical and tropical regions the use of hay and silage is not as widespread.

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

open access: yesAdvanced 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

Regulation of Ant Foraging: A Review of the Role of Information Use and Personality

open access: yesFrontiers in Psychology, 2020
Animals live in heterogeneous environments where food resources are transient and have to be exploited rapidly. Ants show a wide range of foraging strategies and this activity is tightly regulated irrespective of the mode of recruitment used.

Dollars for Drops: Abatement Cost of Water for Irrigation in the Colorado River Basin

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The Colorado River is a lifeline for more than 40 million people in the western United States. However, with climate change diminishing snowpacks in the Rocky Mountains and increasing demands from agriculture and urban areas, the river's flow has become insufficient to meet all the competing needs.

Environmental Determinants of Foraging Site Revisitation by African Elephants (Loxodonta africana)

open access: yesEcology and Evolution
Understanding the spatial patterns of herbivore habitat use is important for understanding ecological processes and ecosystem management. Past research has mainly focused on explaining herbivore habitat selection, to the extent that environmental ...

Movers and shakers: Bumble bee foraging behavior shapes the dispersal of microbes among and within flowers

open access: yesEcosphere, 2019
Dispersal is central to the ecology and evolution of spatially structured communities. While flower microbial communities are spatially structured among floral organs, how dispersal vectors distribute microbes among floral organs is unknown.

Review of the Challenges and Prospects in Agrivoltaics

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This articles reviews the recent prospects of agri‐photovoltaics (agri‐PV) across continents. The existing standards and pilot projects to standardize new codes and regulations are discussed. The state‐of‐the‐art agri‐PV scheme's benefits and lackings are presented. Community acceptance and policy barriers are also discussed where prospective solutions
