Governance and infrastructure as pillars of performance: A socio‐ecological analysis of Ethiopian botanical gardens

PLANTS, PEOPLE, PLANET, EarlyView.
While botanical gardens are often perceived merely as recreational spaces for a weekend walk, in the Global South, they are true lifelines for nature and for the people who depend on it. Our research in Ethiopia explored what actually keeps these gardens running long‐term.

Towards operational assimilation of surface‐sensitive microwave radiances over land at Environment and Climate Change Canada: Investigation of key factors using a 1D‐EnVar framework

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The study evaluates five factors affecting the assimilation of surface‐sensitive Advanced Microwave Sounding Unit‐A (AMSU‐A) radiances over land, including the simultaneous estimation of surface emissivity and the standard set of state variables, to improve numerical weather prediction (NWP) at Environment and Climate Change Canada (ECCC).

Geomorphic Responses to Post‐Grazing Recovery and Stream Restoration in Semiarid Grassland Streams

River Research and Applications, EarlyView.
ABSTRACT Semiarid grassland streams are sensitive to land use, climate, extreme discharges, and internal geomorphic thresholds that drive episodic erosion. Rooted in a process‐based philosophy and commonly applied to historically wood‐rich, beaver‐modified systems, low‐tech process‐based restoration using structures is increasingly being extended to ...

Unveiling and advancing grassland degradation research using a BERTopic modelling approach

Journal of Integrative Agriculture
Grassland degradation presents overwhelming challenges to biodiversity, ecosystem services, and the socio-economic sustainability of dependent communities. However, a comprehensive synthesis of global knowledge on the frontiers and key areas of grassland

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Population Dynamics of Northern Pearl Dace Margariscus nachtriebi in Anthropogenically Altered Headwater Streams of the Nebraska Sandhills Ecoregion

River Research and Applications, EarlyView.
ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...

Fundamental Hydraulic Geometry Relations as an Accessible Tool for Identifying Channel Instability Over National Scales

River Research and Applications, EarlyView.
ABSTRACT The geometry of alluvial river channels can give insight into their stability, which can inform predictions of morphological change, flood risk and ecological degradation. Fundamental hydraulic geometry relations can be used to estimate the equilibrium dimensions of stable river channels by evaluating the balance between the erodibility of bed
