Informal supply chains of wild meat from rural Amazonia and food security in an urban center
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Iquitos, the most populated city in the Peruvian Amazon, is a hub in the regional supply chain of wild meat and supplies urban consumers. Studies on wild meat consumption have focused primarily on markets, limiting the scope of species considered to those that are economically valuable and potential inferences from those data.

野生动物学报, 2017 大袋鼠在中国动物园内广泛饲养,动物园普遍沿用传统的饲养经验进行饲养,没有统一的饲养标准和规范,饲喂食物品种和数量有较大差异。不同的饲喂方式导致大袋鼠的饲养效果出现明显差异。口腔疾病和肠道梗阻问题是大袋鼠饲养中较常出现的疾病,为大袋鼠的饲养带来了困难。本文根据国内外大袋鼠的饲养资料文献,结合南京市红山森林动物园饲养实践,从大袋鼠的饮食习性、基础日粮、饲喂方法、大袋鼠对水的需求等4个方面对圈养条件下大袋鼠的饲料情况进行了分析和探讨。

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and
