The fate of Acacia [PDF]

TAXON, 2011
AbstractWe propose a once‐off "special committee" to developed a proposal that could resolve the entrenched positions in the case of the typification of Acacia. It is important that such a proposal has a broad, consensual, support, rather than rely on a "winner takes all" approach.

The green side of social innovation: Using sustainable development goals to classify environmental impacts of rural grassroots initiatives

Environmental Policy and Governance, Volume 32, Issue 6, Page 459-477, December 2022., 2022
Abstract Social innovations are grassroots processes aiming to achieve impacts beyond an individual level and towards a broader societal good. The environmental dimension of impacts refers to any direct change to the environment resulting from social innovation activities, products, or services, which are not addressed by pre‐existing systems.

Silica‐gel incorporated carbon paste sensor for the electrocatalytic oxidation of famotidine and its application in biological sample analysis

Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Graphical Abstract. Abstract Famotidine (FAM) is an efficacious competitive drug, and a reversible inhibitor of H2‐histaminergic receptor action used to manage acid production in the stomach. Among the elderly population, this drug poses the risk of kidney failure and impaired mental health conditions. Additionally, FAM is an environmental contaminant.

Exploration of agricultural residue ash as a solid green heterogeneous base catalyst for biodiesel production

Engineering Reports, Volume 5, Issue 1, January 2023., 2023
Transesterification of vegetable oils with homogeneous catalyst for biodiesel synthesis is considered to have a promising future, but it is nonrenewable and hazardous. High production cost, in terms of feedstock oil and catalyst acquisition is one of the major challenges facing the global commercialization of biodiesel.

Coherent changes in wood charcoals, site occupation and lithic technology across the MIS 4/3 transition at Klein Kliphuis rock shelter, South Africa

Journal of Quaternary Science, Volume 38, Issue 1, Page 38-48, January 2023., 2023
Abstract We explore the correspondence between changing palaeoenvironments, patterns of site use, and lithic technology at the rock shelter site Klein Kliphuis (South Africa) across the interval 65–55 000 years before present. This period coincides with the termination of Marine Isotope Stage (MIS) 4, and the disappearance of an iconic late Pleistocene

Tropical surface gold mining: A review of ecological impacts and restoration strategies

Land Degradation &Development, Volume 33, Issue 18, Page 3661-3674, December 2022., 2022
Abstract Surface gold mining severely degrades landscapes, causing deforestation, soil erosion and displacement, and toxic contamination. The prevalence of both large‐scale and artisanal, small‐scale surface gold mining in the tropics has risen over recent decades.

A structural study of Acacia nilotica and Acacia modesta gums [PDF]

Carbohydrate Polymers, 2017
Superficially similar carbohydrate polymers from similar sources can have dramatically different characteristics. This work seeks to examine the molecular properties responsible for these differences. Protons responsible for cross-polarization in the anomeric region of Acacia nilotica (AN) were replaced easily by deuterium, but not for Acacia modesta ...

Defining biodiverse reforestation: Why it matters for climate change mitigation and biodiversity

PLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 27-38, January 2023., 2023
Mixed species plantings present an attractive alternative to monoculture reforestation through their added benefits to biodiversity. Yet there is ambiguity in the use of the term ‘biodiversity’ in carbon and biodiversity markets, which may create perverse outcomes when designing schemes and projects.

An ecological and evolutionary perspective of the historical US nursery flora

PLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 146-159, January 2023., 2023
The plants sold in nurseries directly influence urban landscapes by providing habitat that supports humans and other organisms and indirectly influence the natural landscape by acting as a major source of invasive species. We analyzed the ornamental plants sold in US nurseries from 1719 to 1946 and found broad patterns of increasing diversity occurring
