What caused Earth's biggest mass extinction? Scientists have debated until now what made Earth's oceans so inhospitable to life that some 96 percent of marine species died off at the end of the Permian period. New research shows the "Great Dying...

Periodic reminder of why we must decarbonize. The Permian extinction was the planet killer. It was caused by - wait for it - greenhouse gas warming: >90% of all species went extinct.
Under business as usual we're 20% the way there by 2100, 35-50% by 2300.

The Caribbean Needs US Climate, Humanitarian Response, Not Military Aggression US role in climate change requires us to help those most affected.

At a time when the US slides dangerously into authoritarianism, people "must reject the use of the vast resources of the country to threaten or carry out military assaults on sovereign nations, and instead demand their use for the life-saving work of humanitarian aid in the wake of a disaster."

New bridging eco-acoustic indices inspired by deep neural networks for fine-grained bird vocalization recognition across diurnal cycles Revealing difference in bird vocalization changes from the perspectives of song recognition and acoustic indices has become a hot topic and challenge in recent ecological landscape research. This paper proposes a fine-grained (Dawn, noon, night) bird vocalization recognition framework based on a two-layer deep network to identify the same species’ bird vocalization at different times of the day. Additionally, a new acoustic index method, the Log-Mel Acoustic Complexity Index (Log-Mel ACI), is introduced to explore the differences in bird vocalization of the same species throughout the day. The results of two-layer deep network showed significant separability of the bird vocalization of the same species at dawn, noon, and night based on Log-Mel spectrum. Furthermore, it was found that the improved ACI based on Log-Mel exhibits better circadian rhythmic performance than the traditional ACI, being highest at dawn, followed by night, and lowest at noon. These findings demonstrate that Log-Mel is effective in both deep network recognition and ACI calculation.

The IUCN Red List of Threatened Species reports today that over 60% of bird species worldwide are in decline, primarily due to habitat loss and degradation and others like psittaciformes (parrots, macaw) and passeriformes (song birds) to live traffic.

There are more cases of Hansen’s disease reported in Brazil than any other nation besides India.

A study carried out by Brazilian researchers and published in May revealed a strong association in Brazil between direct contact with armadillos and a high risk of contracting Hansen’s disease.
