Subsistence hunting shapes the spatial variation of jaguar densities in community‐managed forests
Journal of Zoology, EarlyView.Jaguars and people can coexist in community‐managed forests, but distance matters. In Guatemala's Maya Biosphere Reserve, jaguar numbers increased markedly in areas harder to reach on foot, yet jaguars were still found near communities, showing that responsibly managed forests can support jaguar populations while allowing people to maintain traditional

Research on Collapse Risk Assessment of Karst Tunnels Based on BN Self-Learning
BuildingsThe high risk of collapse is a key issue affecting the construction safety of karst tunnels. A risk assessment method for karst tunnel collapse based on data-driven Bayesian Network (BN) self-learning is proposed in this study.

Subterranean glacial spillways: an example from the karst of South Wales, UK [PDF]
, 2013 Many karst areas in the UK have been glaciated one or more times during the last 0.5 Ma, yet there are few documented examples of caves in these regions being affected by glacial processes other than erosion.

Long‐term effects of clear‐cutting forestry on ectomycorrhizal fungi in boreal forest
New Phytologist, EarlyView.Summary Clear‐cutting is detrimental to ectomycorrhizal fungi in a short time perspective, but long‐term effects on species richness and community composition are uncertain. To evaluate ecological sustainability of rotation forestry, we examined to what extent communities similar to those in old forests develop within the time frame of a rotation ...

Development of a Sinkhole Raveling Chart Based on Cone Penetration Test (CPT) Data [PDF]
, 2018 Naturally occurring sinkholes in Florida are formed when the soluble limestone bedrock weathers and creates cavities at its interface with the overburden finer-grained soils. The overburden soil then erodes into the limestone fissures, thus weakening the

Sedimentology, EarlyView.ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

Halite karst geohazards (natural and man-made) in the United Kingdom [PDF]
, 2002 In the United Kingdom Permian and Triassic halite (rock salt) deposits have been affected by natural and artificial dissolution producing karstic landforms and subsidence.
