Multi‐scale geophysical mapping of the brine and bedrock surfaces along the Dolores River, Paradox Valley, Colorado, December 2023

open access: yesNear Surface Geophysics, EarlyView.
Abstract Total dissolved solids derived from salt dome–sourced brine in the underlying alluvial aquifer substantially increase with distance in the reach of the Dolores River that passes through Paradox Valley in southwestern Colorado. The area has been the site of salinity control operations since the 1990s to reduce salt loading to the downstream ...

The Effect of Testing Lag on Chemical Indexes of Karst Water

open access: yesYankuang ceshi, 2019
BACKGROUND Sample testing is important for studying hydrogeology, engineering geology and environmental geology in Karst areas. The inconvenience of transportation, the difficulty of sample shipping and the delayed sample analyses by testing laboratory ...

Whole‐seedling trait adjustments of mountain birch under contrasting environmental conditions

open access: yesOikos, EarlyView.
Warming temperatures can promote arctic tree seedling establishment and growth, but these effects depend on the environmental context and the seedlings' capacity to acquire limiting resources. Here, we tested how temperature, soil properties, and the presence of a neighbouring shrub influence seedling growth rates.

Spatiotemporal evolution of landscape stability in World Heritage Karst Sites: a case study of Shibing Karst and Libo-Huanjiang Karst

open access: yesHeritage Science
Landscape stability is a paramount concern within the field of landscape ecology. Indices of landscape patterns not only facilitate an effective analysis of land use transformations but also delve into the mechanisms of landscape disturbances across ...

The initial stages of cave formation: Beyond the one-dimensional paradigm

open access: yes, 2010
The solutional origin of limestone caves was recognized over a century ago, but the short penetration length of an undersaturated solution made it seem impossible for long conduits to develop.

Exploring narratives of human–nature connections in protected areas

open access: yesPeople and Nature, EarlyView.
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.

Simulated elephant foraging alters tree root exudation rates: Species‐specific responses and implications for belowground carbon dynamics in tropical forests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Asian elephants play crucial roles in ecosystem functioning, and their interactions with plants influence above‐ and belowground carbon cycling. We tested whether their mechanically destructive foraging triggers short‐term, stress‐induced shifts in tree root exudation, an underappreciated pathway linking herbivory to belowground carbon processes.

Occurrence of 'Antrobathynella stammeri' (Jakobi, 1954) (Crustacea: Syncarida: Bathynellidae) in the hyporheic zones of two English karst rivers [PDF]

open access: yes, 2008
This paper reports the first records of Antrobathynella stammeri in the British Isles since 1985. Numerous individuals were observed in hyporheic water extracted from the River Skirfare (Yorkshire, UK), whilst, in an independent study, a single confirmed
