Humanity could vanish from the Earth right now, and our legacy would still linger for a thousand years. The world is waking to the reality of anthropogenic climate change, but that’s not the full story when it comes to how we’ve remade this planet in our image . Our obsession with plastic has flooded our environment with millions of tons of plastic waste, and every crevice of the planet is now filled with plastic fragments, small and large.Continue reading
Wallabies living near humans breed later in the season, potentially missing valuable resources that could mean the difference between life and death for their growing offspring.
New research published last month in Proceedings B that found that light pollution in Australia is putting the tammar wallaby (Macropus eugenii) out of sync with the seasons. Robert and colleagues from La Trobe University in Melbourne studied wallaby breeding near urban areas and in natural bush, and found that human light pollution prevents the marsupials from responding to light cues that normally signal the start of the breeding season. Wallabies living near humans had lower levels of melatonin, a hormone linked to the sleep-wake cycle, and gave birth on average 27 days later than wallabies in wild conditions. The authors say that this may lead to a mismatch between the birth of young wallabies and food availability.
