Coyotes, bears and more are enjoying areas usually reserved for crowds of human visitors

Most of the animals at the B.C. Wildlife Park in Kamloops are unfazed by the absence of paying visitors since it closed in March over COVID-19 concerns. But Blue the turkey appears "bummed," staff say.

Ingrid Newkirk isn’t sure exactly how many times she has been arrested. “Definitely a few dozen,” she’ll say, if you ask. I’ve just done exactly that, so right now the British-born founder of People for the Ethical Treatment of Animals (PETA) is running me through a sort of greatest hits of her law-baiting exploits and the jailtime they have brought her in the name of animal rights.

The capacity to extract oxygen from the environment and transport it to respiring tissues in support of metabolic demand reportedly has implications for species’ thermal tolerance, body-size, diversity and biogeography. Here we derive a quantifiable linkage between maximum and basal metabolic rate and their oxygen, temperature and size dependencies. We show that, regardless of size or temperature, the physiological capacity for oxygen supply precisely matches the maximum evolved demand at the highest persistently available oxygen pressure and this is the critical PO₂ for the maximum metabolic rate. For most terrestrial and shallow-living marine species, this "P_crit-max" is the current atmospheric pressure, 21 kPa. Any reduction in oxygen partial pressure from current values will result in a calculable decrement in maximum metabolic performance. However, oxygen supply capacity has evolved to match demand across temperatures and body sizes and so does not constrain thermal tolerance or cause the well-known reduction in mass-specific metabolic rate with increasing body mass. The critical oxygen pressure for resting metabolic rate, typically viewed as an indicator of hypoxia tolerance, is, instead, simply a rate-specific reflection of the oxygen supply capacity. A compensatory reduction in maintenance metabolic costs in warm-adapted species constrains factorial aerobic scope and the critical PO₂ to a similar range, between ~2 and 6, across each species’ natural temperature range. The simple new relationship described here redefines many important physiological concepts and alters their ecological interpretation.

Dramatically rising costs in drug development are in large part because of the high failure rates in clinical phase trials. The poor correlation of animal studies to human toxicity and efficacy have led many developers to question the value of requiring animal studies in determining which drugs should enter in-human trials. Part 1 of this 2-part series examined some of the data regarding the lack of concordance between animal toxicity studies and human trials, as well as some of the potential reasons behind it. This second part of the series focuses on some alternatives to animal trials (hereafter referred to as animal research) as well as current regulatory discussions and developments regarding such alternatives.

US government vets said to be ready to assist with culls, or ‘depopulation’ of pigs, chickens and cattle because of coronavirus meat plant closures

Covid-related slaughterhouse shutdowns in the US are leading to fears of meat shortages and price rises, while farmers are being forced to consider “depopulating” their animals.

More than 20 slaughterhouses have been forced to close, although some have subsequently reopened. On Tuesday President Trump issued an executive order to keep slaughterhouses open which would, he said, help solve liability problems for meat companies.
