Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Summer habitat use of plateau pikas (Ochotona curzoniae) in response to winter livestock grazing in the alpine steppe Qinghai-Tibetan Plateau

Arctic, Antarctic, and Alpine Research, 2018
Plateau pikas (Ochotona curzoniae), burrowing lagomorphs endemic to the Qinghai-Tibetan Plateau (QTP), are considered pests by Chinese authorities because of their association with grasslands that are characterized as degraded.

The evolutionary psychology of the human pointing gesture

Mind &Language, EarlyView.
The human pointing gesture is a species‐unique and species‐universal form of communication that depends on humans' especially powerful forms of cooperative cognition and motivation. I have previously hypothesized that the pointing gesture evolved as a behavioral tool empowering individuals to better coordinate their interdependent collaborative ...

ARE PIKAS EXPOSED TO AND AFFECTED BY SELENIUM DEFICIENCY? [PDF]

Journal of Wildlife Diseases, 2007
Regional extirpations of pikas (Ochatona princeps) within the last few decades have been attributed to global warming. Other recent global alterations such as increased nitrogen (N) deposition and associated selenium (Se) deficiency may further stress pika populations.

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

Globo‐H diagnostic stratification and identification of DUSP14 as a candidate target in colorectal cancer

International Journal of Cancer, Volume 159, Issue 4, Page 936-950, 15 August 2026.
What's new? Colorectal cancer (CRC) is increasingly complicated by drug‐resistant tumors that limit the effectiveness of anticancer therapies. Because resistance mechanisms vary among patients and can evolve over time, personalized treatment strategies are needed.
