Seems worth noting this award in light of the present circumstances. Get the troops out of our fair city please, perhaps after they enjoy a great Malnatiโ€™s pizza!

If conservationists work from a compromised baseline, our notions of abundance, scarcity, and ecological wellbeing will keep getting defined downward:
"The researchers show that using the 1970s as a baseline tends to normalize an already severely degraded state."

The transition of vegetation from the lowly water-stressed forest with high tree cover to a savanna-grassland regime with low tree cover and the utilization of rootzone storage capacity to cope with the spatial change to a drier climate.

Indigenous groups criticize Ecuadorโ€™s $47 billion oil expansion plan in Amazon Ecuadorโ€™s plans to offer dozens of blocks of land for oil exploration for more than $47 billion has prompted opposition from seven Indigenous peoples in the Amazon.

โ€œEcuadorโ€™s plans to auction new oil blocks in the Amazon are doomed to fail. Indigenous resistance, civil society mobilization, & growing international pressure will continue to expose these projects as illegitimate, unlawful, & unfinanceable.โ€-Kevin Koenig of @AmazonWatch apnews.com/article/oil-...

It really helps to think of all vertebrates as fish. The position of the anus is a very stable feature of the vertebrate body plan, indicated by the red arrows in these images of embryos in four species.

The position of the anus is a core feature of the vertebrate body plan. And there are really no other landmarks on the belly side of a developing vertebrate to help guide gene expression and cellular differentiation.

A new study shows that the earliest gobioid fishes were coral-reef associated dwarfs. Results suggest that dwarf gobies achieved ecological success early in gobioid evolution, arising through convergent evolution across different lineages๐ŸŸ Read more: buff.ly/GVMpJaF

Although chromosome-level macrosynteny is broadly conserved among cypriniforms, we demonstrate that microsynteny can resolve deep phylogenetic nodes. Both sequence-based and microsynteny-based analyses find that Gyrinocheilidae is the sister lineage to all other cypriniforms

Why do black-and-white stripes deter biting flies from landing on surfaces? This phenomenon has been explained as modulation brightness or polarized light. A similar explanation is confusion of insect motion detection systems that control their approach and landing.
