The role of botany in the development of the Republic of South Africa with special emphasis on the contributions of the Botanical Research Institute

Bothalia: African Biodiversity & Conservation, 1979
Five papers cover different aspects of the contributions to and role of botany in the development of the Republic of South Africa. Two papers sum up the contributions for the non-agricultural and agricultural sectors. The introductory paper by D. J. B.

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.

Assessing the levels of food shortage using the traffic light metaphor by analyzing the gathering and consumption of wild food plants, crop parts and crop residues in Konso, Ethiopia

Journal of Ethnobiology and Ethnomedicine, 2012
Background Humanitarian relief agencies use scales to assess levels of critical food shortage to efficiently target and allocate food to the neediest. These scales are often labor-intensive.

Facilitating macrosystem biology with organismal‐scale airborne remote sensing: Challenges and opportunities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Emergent ecosystem properties, such as population and trait distributions, biodiversity and energy and water fluxes, occur because of the dynamic interactions of individuals in their environment.

Developing High-Efficiency PCR Mini-Barcoding to Enforce Conservation Efforts Against Illegal Trade and Habitat Loss of Endangered Taxus L. in the Himalayas

Conservation
Environmental and ancient DNA are mostly present in degraded forms in nature. Plant forensics is necessary for plants like Taxus (Taxaceae), which is a medicinal, as well as poisonous, endangered plant.

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Robust estimation of key leaf traits from reflectance spectroscopy of herbarium specimens

Methods in Ecology and Evolution, EarlyView.
Abstract Community‐wide efforts to digitize herbarium specimens have facilitated novel uses of specimen data across scales. However, the need for destructive sampling has prevented large‐scale examination of foliar functional traits. We demonstrate that nondestructive reflectance spectra are an effective tool for estimating leaf traits from herbarium ...

Multi‐angle, cross‐domain fusion strategy enhances automated insect identification and hierarchical categorization: a case study on assassin bugs (Hemiptera: Reduviidae)

Cladistics, EarlyView.
Abstract Automated insect identification systems hold significant value for biodiversity monitoring, pest management, citizen science initiatives and systematic studies, particularly in an era of declining expertise in insect taxonomy. However, current deep learning approaches often rely on standardized specimen photos from limited‐angles and ...

A framework for maximizing the benefit from retaining regrowth on private land

Conservation Biology, EarlyView.
Abstract Conservation interventions often have lower‐than‐desired positive impacts, as revealed by retrospective counterfactual‐based evaluations. To address this, a prospective counterfactual‐based approach can be used to estimate potential benefits and design conservation interventions to maximize outcomes. We developed a framework for estimating the
