While site fidelity may be beneficial for animals when environmental conditions don’t change very fast, those benefits may not be realized in the ever-changing world dominated by humans, researchers have found through a review of scientific literature.

Symposium addresses drug development against SARS-CoV2
Researchers reporting in ACS’ Environmental Science & Technology Letters have developed a passive air sampler clip that can help assess personal exposure to SARS-CoV-2, which could be especially helpful for workers in high-risk settings, such as restaurants or health care facilities.

An estimated 370,000 Californians rely on drinking water that may contain high levels of arsenic, nitrate or hexavalent chromium, and contaminated drinking water disproportionately impact communities of color in the state, finds a new analysis led by researchers at the University of California, Berkeley, and the University of California, Los Angeles. Because this study is limited to three common contaminants, results likely underestimate the actual number of Californians impacted by unsafe drinking water.

Calves raised during the heat of summer have reduced growth, increased disease incidence, and higher mortality rates compared with those raised in temperate environments or neutral thermal conditions. The reduced average daily weight gain observed in the summer can be partially attributed to heat stress. In a new report published ahead of the February 2022 issue of the Journal of Dairy Science®, scientists from the University of Georgia (Athens, GA, USA) investigated the effects of rate and frequency of milk replacer feeding on performance, emptying of the abomasum (one of the bovine forestomachs), and nutrient digestibility among young calves during summer and winter in the warm environment of the southeastern United States.
