Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

Unraveling algae and cyanobacteria biodiversity in bromeliad phytotelmata in different vegetation formations in Bahia State, Northeastern Brazil

Acta Botânica Brasílica, 2018
Knowledge of algal and cyanobacterial diversity of phytotelmata remains poorly-known, especially for bromeliads from different vegetation formations. We investigated the microalgae communities of four species of tank bromeliads from different vegetation ...

Carbon–Phosphorus Limitation Is Associated With Shifts in Microbial Life‐History Strategies Across Vegetation Restoration Modes in Alpine Sandy Land on the Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Alpine sandy land on the Tibetan Plateau is fragile, with poorly developed soils, low nutrient availability, and weak biological resilience. Vegetation restoration is widely used to improve soil functioning, yet how microbial nutrient limitation and life‐history strategies vary among restoration modes remains unclear.

Higher NO3−‐N Levels Under Mulberry (Morus alba L.) Planting Enhanced CAZyme Abundance, Increasing Soil Carbon Stability

Land Degradation &Development, EarlyView.
ABSTRACT Afforestation is widely advocated for boosting carbon (C) sequestration. However, the stability of soil C pools in economically and culturally significant mulberry plantations remains poorly understood. The soil organic C (SOC) contents in different aggregates and the oxidizable OC fractions were measured.

Synergistic Regulation of Soil Function and Wind Erosion Resistance by Sand Barriers, Vegetation, and Artificial Biological Crust in the Tengger Desert

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian desertification poses a critical threat to ecosystem stability in arid regions worldwide. Although the combination of sand barriers and vegetation has been widely applied for sand fixation, its long‐term effectiveness is constrained by barrier degradation, slow natural development of biological soil crusts (BSCs), and the resulting ...

Microhabitat use by small mammals in even-aged forest stands

, 1986
Microhabitat use by Sorex cinereus, Peromyscus leucopus and Clethrionomys gapperi was examined in small, even-aged stands of aspen (Populus spp.) and mixedoak (Quercus spp.) from July to September for 3 years in central Pennsylvania.

Mixed Litter Decomposition Drives Functional Gene Rearrangement in the Microbial Carbon Cycle

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how mixed‐species litter decomposition regulates microbial communities and carbon cycling is vital for guiding ecosystem restoration and climate change mitigation, as it is a key process for nutrient cycling and carbon sequestration. A 15‐month field experiment compared single‐species (Pinus sylvestris var.
