Ecological and Cenotic Activity of Species of the Middle Taiga Flora

Lesnoy Zhurnal (Forestry Journal), 2022
The control of the main weeds of forestry objects has always played an important role in forestry. The development of evidence-based measures, primarily in the areas of forest nurseries, relies on identifying the features of formation, functioning and activity of segetal plant species.

From Social Justice to Indigenous Peoples' Rights: Continuities and (Re)framings in Ejido Property Claims in Yucatán, Mexico

Journal of Agrarian Change, EarlyView.
ABSTRACT This article examines how long‐standing local conflicts concerning the nature of common property, the distribution of access and administrative rights associated with it, and more broadly the nature of the community and the forms of citizenship that organise its governance shape demands for justice regarding land transfers to outside investors

Seismic Reflection Profiling at the Kentland Impact Structure, Indiana: Geophysical Characterization of Impact Induced Damage

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract The Kentland Impact Structure is a classic complex crater whose central peak is exposed in an active quarry in NW Indiana, USA. However, its diameter has remained poorly constrained due to the thick glacial sediment cover. Newly obtained seismic reflection profile images combined with refraction seismic tomography, earlier gravity surveying ...

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, Volume 55, Issue 3, Page 768-789, July 2026.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, Volume 64, Issue 4, Page 405-421, July/August 2026.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.
