Effectiveness of integrated shrub management and restoration techniques for rehabilitating shrub‐encroached rangelands of South Africa

Grassland Research, EarlyView.
Herbaceous plant recovery following shrub clearing and reseeding in the rangelands of Peddie, Eastern Cape of South Africa. CTL, control; CO, cutting only; CR, cutting and reseeding; UPO, uprooting only; UPR, uprooting and reseeding. Abstract Background Shrub encroachment (SE) drives rangeland degradation, threatening biodiversity and forage ...

Experimental Assessment of the Effects of Substrate Choice on the Duration of Chemical Signals in Fecal Scent‐Marks of Free‐Ranging Iberian Wolves

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Chemical communication, typically based on feces, urine, and glandular secretions, often deposited as substrate scent marks, plays a key role in social organization and communication among many mammals, especially carnivores. This study assesses experimentally whether the type of substrate chosen for fecal deposition and the temperature ...

Diurnal Air–Surface Temperature Dynamics in Hong Kong: An Analysis Across Land Use and Climate Zones

International Journal of Climatology, EarlyView.
Daytime and nighttime air temperature (Ta) from automatic weather stations and land surface temperature (Ts) derived from ASTER and Landsat 8–9 are used to examine the relationship between Ta and Ts. The spatial and statistical characteristics of Ta − Ts dynamics are further analysed across land use (LU) and local climate zones (LCZ).

How Well Is Surface Diurnal Temperature Range Represented by Observations at 2‐m Level

International Journal of Climatology, EarlyView.
We demonstrate that geostationary satellites depict well the Diurnal Temperature Range (DTR) in the US but differ from information at 2 m level from model outputs. Upper: mean diurnal temperature range (DTR) using GOES‐E based land surface temperature (LST) for January (left) and July (right) during 2004–2009. Lower: mean diurnal temperature range (DTR)

Direct Geologic Constraints on the Timing of Late Holocene Ice Thickening in the Amundsen Sea Embayment, Antarctica

Geophysical Research Letters
Constraining past West Antarctic Ice Sheet (WAIS) change helps validate numerical models simulating future ice sheet dynamics. Following rapid deglaciation during the mid‐Holocene, ice near Thwaites Glacier was ∼35 m thinner than present; however, the ...

The Emergence of a Climate Change Signal in Ireland's Rainfall Extremes

International Journal of Climatology, EarlyView.
Analysis of Irish precipitation records (1930–2019) shows significant relationships between rainfall extremes and global mean surface temperature (GMST), with increases of 12%–27% per °C of warming. Emergence of unusual climate conditions is already evident at several stations, most notably in the west during winter and the southeast during summer ...

Marine Benthic Habitat Mapping of Muir Inlet, Glacier Bay National Park and Preserve, Alaska With an Evaluation of the Coastal and Marine Ecological Classification Standard III [PDF]

, 2010
Seafloor geology and potential benthic habitats were mapped in Muir Inlet, Glacier Bay National Park and Preserve, Alaska, using multibeam sonar, ground-truth information, and geological interpretations. Muir Inlet is a recently deglaciated fjord that is
