Sinkhole Physical Models to Simulate and Investigate Sinkhole Collapses

open access: yesSinkholes and the Engineering and Environmental Impacts of Karst: Proceedings of the Fourteenth Multidisciplinary Conference, 2015
Florida is one of the most susceptible states for sinkhole collapses due to its karst geology. In Florida, sinkholes are mainly classified as cover subsidence sinkholes that result in a gradual collapse with possible surface signs, and cover collapse sinkholes, which collapse in a sudden and often catastrophic manner.

Exploring narratives of human–nature connections in protected areas

open access: yesPeople and Nature, Volume 8, Issue 1, Page 37-50, January 2026.
Abstract Protected areas have become the most widespread strategy for nature conservation, and are currently expanding worldwide. Many of them are inhabited or close to inhabited areas, shaping and being shaped by connections between people and nature. These connections are not always positive.

Multi‐Scale Habitat Selection of Greater Caribbean Manatees in Sian Ka'an Biosphere Reserve, Mexico

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Habitat selection describes population distribution as a function of environmental features. It is a fundamental process with primordial ecological and evolutionary implications. To accurately describe habitat selection, it is important to identify temporal and spatial scales perceived by the population and use these scales when modeling ...
