Clock Ticking for Mexican Wolf and Recovery Plan

After 30-plus years of wrangling, wildlife managers have yet to agree on a revised recovery plan for the endangered Mexican wolf. As a November deadline looms, a study by the Arizona Game and Fish Department and British Columbia’s Wildlife Genetics International offers guidance for finding common ground.

Zoo Conservation Center Pulls Native Species Back from the Brink

As Congress eases rules for selling public lands and considers measures to weaken the Endangered Species Act, conservation efforts may rely increasingly on private facilities like the Phoenix Zoo, which supports its Arthur L. and Elaine V. Johnson Foundation Native Species Conservation Center with a portion of its gate receipts.

For 11 years, volunteer citizen scientists have gathered near Seligman, Arizona, to help spot, capture and release endangered black-footed ferrets. The outing is part of a program to monitor captive-bred ferrets that wildlife specialists began reintroducing to Aubrey Valley 20 years ago.

This year, I joined them.

Long before they develop neurofibrillary tangles or beta-amyloid plaques, brains with Alzheimer’s disease begin experiencing problems in their cells’ power plants — the mitochondria — that hinder their ability to make energy for cells.

Declines in gene expression related to mitochondria can occur in subjects as young as their early 30s.

Rude Burials Might Have Fueled Blood Feuds Among Ancient Sonorans

Bodies buried  in unusual postures and without funeral rites could suggest a history of revenge and blood feud in certain ancient Sonoran Desert cultures, according to a paper in the August 2016 edition of Current Anthropology.

The authors say a rude burial would have deeply distressed the victim’s family and community — and sent a message of dominance and defiance. Read/listen to my full story at KJZZ’s Arizona Science Desk:
