Gypsum dissolution geohazards at Ripon, North Yorkshire, UK [PDF]

, 2007
This guide is for a one-day field excursion to examine gypsum dissolution geohazards at Ripon in North Yorkshire. Gypsum is a highly soluble rock and under suitable groundwater flow conditions it can dissolve forming caves and karstic features including ...

Ostracode-based aminostratigraphy and aminochronology of a tufa system in central Spain [PDF]

, 2005
In the Priego area, central Spain, extensive tufa deposits are located in three small tributaries located at the head of the 1000 kmlong Tagus River. The deposits are originated after karst-origin running waters emerged from the confines of the canyons ...

First Report of Sydowia polyspora Causing Current Season Needle Necrosis on Abies grandis in Sweden

Forest Pathology, Volume 56, Issue 1, February 2026.
ABSTRACT Current season needle necrosis (CSNN) is a conifer foliar disease and a particular problem for Christmas tree plantations, as it causes necrosis and premature foliage shedding, resulting in significant economic and aesthetic devaluation. In September 2022, CSNN symptoms were detected on 10‐year‐old Abies grandis trees at a plantation located ...

Numerical simulation of critical flow velocity in the covered karst soil cave formation

Shuiwen dizhi gongcheng dizhi
The covered karst collapse has the characteristics of concealment, suddenness, uncertainty, and mechanism complexity, which leads to its prevention and treatment more difficult. In the process of covered karst collapse, soil caves formed in the overlying

Phenological Shifts in Wood Formation Tracked by Frost Rings Across Two Centuries

Global Change Biology, Volume 32, Issue 2, February 2026.
Rapid warming is reshaping plant phenology across ecosystems. We present an indirect retrospective approach to infer cambial phenology by analysing the timing and occurrence of frost rings in three Alpine conifers. We found that the cold spells responsible for frost ring formation typically involve temperature dropping below freezing for an average of ...

New insights into the genesis of the Miocene collapse structures of the island of Gozo (Malta, central Mediterranean Sea) [PDF]

, 2015
The large palaeosinkholes located in the NW of Gozo (central Mediterranean Sea, Malta) offer excellent exposures that provide information on the geometry and kinematics of large karst-related collapse structures.

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

Population Ecology, Volume 68, Issue 1, January 2026.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...
