TL;DR: In this article, a new conceptual model was proposed to describe the mechanisms and consequences of biodiversity change in fragmented landscapes, identifying the fragmentation threshold as a first step in a positive feedback mechanism that has the capacity to impair ecological resilience, and drive a regime shift in biodiversity.

TL;DR: It is shown that an annual investment equivalent to 6.5% of what Brazil spends on agricultural subsidies would revert species composition and ecological functions across farmlands to levels found inside protected areas, thereby benefiting local people, and efforts to secure the future of this and other biodiversity hotspots may be cost-effective.

TL;DR: The importance of niche-based and neutral processes to species extinction and community assembly across a gradient of habitat loss is unveiled, challenging the predictions of neutral models and underscore the fundamental importance of pro-active measures to prevent human-modified landscapes surpassing critical ecological thresholds.

TL;DR: It is argued that dismissing habitat fragmentation as a powerful force driving species extinction in tropical forest landscapes is premature and unsafe.

TL;DR: Anualemente, el zorro es mas generalista que el aguara guazu, pero en lo que se refiere a habilidades de captura, el agUara parece ser capaz de manipular mas tipos of presas y frutos diferentes.
