Universal restrictions to the conversion of heat into work derived from the analysis of the Nernst theorem as a uniform limit

open access: yes, 2003
We revisit the relationship between the Nernst theorem and the Kelvin-Planck statement of the second law. We propose that the exchange of entropy uniformly vanishes as the temperature goes to zero. The analysis of this assumption shows that is equivalent

Harnessing social media data to track species range shifts

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

A practical, adaptive compliance management framework for improving marine protected area effectiveness

open access: yesConservation Biology, EarlyView.
Abstract Noncompliance regularly undermines the effectiveness of marine protected areas (MPAs) worldwide. The reasons for and drivers of noncompliance depend on the context (e.g., insufficient funding, capacity, neocolonialism, historical conflict), but the prevalent solution offered to curtail noncompliance tends to be more or better enforcement.

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty

open access: yesConservation Biology, EarlyView.
Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...
