Mallard response to experimental human disturbance on sanctuary areas is mediated by hunting

Wildlife Biology, Volume 2026, Issue 2, March 2026.
Wildlife managers often provide spatial sanctuaries for wildlife to escape both lethal (e.g. hunting) and non‐lethal (e.g. non‐consumptive recreation) human disturbance. However, as societal interest in outdoor recreation continues to climb, many areas face added pressure to allow recreation, yet studies increasingly demonstrate negative effects of ...

Assessing Ecological Conditions of Microtopography for Vegetation Restoration on the Chinese Loess Plateau [PDF]

Nature Environment and Pollution Technology, 2020
Microtopographies affect large portions of the Chinese Loess Plateau after years of water erosion. Vegetation restoration has proven to be an effective way to conserve water and soil, however, studies of the influence of microtopography on naturally ...

Using [delta] ph as a geochemical index of illite neoformation in saprolite [PDF]

, 2008
Sal pH is routinely measured for agronomic purposes. When the difference between KCI pH and H2O pH, or ApH, yields positive values, it is used by soil scientists as a classification criterion for identifying anionic subgroups according to the Soil ...

N II 5668-5712, a New Class of Spectral Features in Eta Carinae [PDF]

, 2011
We report on the N II 5668-5712 emission and absorption lines in the spectrum of Eta Carinae. Spectral lines of the stellar wind regions can be classified into four physically distinct categories: 1) low-excitation emission such as H I and Fe II, 2 ...

Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...

A new view from La Cotte de St Brelade, Jersey [PDF]

, 2014
Did Neanderthal hunters drive mammoth herds over cliffs in mass kills? Excavations at La Cotte de St Brelade in the 1960s and 1970s uncovered heaps of mammoth bones, interpreted as evidence of intentional hunting drives.

Exploring Electrical Resistivity Tomography (ERT) to Detect Soil Pipes: Theoretical Modeling and Field Experiments

Land Degradation &Development, Volume 37, Issue 3, Page 1126-1142, 15 February 2026.
ABSTRACT Soil erosion research remains critical for sustainable development as it impacts soil health through different erosive processes. Recent studies on soil piping highlight advancements in detecting surface features (using UAV); however, detecting underground pipes still remains challenging.

Grèzes litées and their genesis: the site of Enscherange in the Rhenish-Ardennes Massif as a case study [PDF]

, 2016
The freeze-thaw cycles in periglacial areas during the Quaternary glacials increased frost weathering, leading to a disintegration of rock formations. Transported downslope, clasts allowed in some areas the formation of stratified slope deposits known as
