Comparative analysis of machine learning algorithms and vegetation indices for mapping Eucalyptus tree woodlots using Sentinel‐2 imagery in the Akaki River catchments

Agrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Eucalyptus trees (ETs) cover approximately 20 million ha globally, with Brazil leading at 5.6 million ha. In Africa, ET plantations span around 1.5 million ha, primarily in South Africa and Ethiopia. In Ethiopia, ET plays a key role in agroforestry, covering 506,000 ha, which represents 90% of all planted trees in the form of woodlots.

Somatic embryos can be induced from the vegetative shoot apex of mature Pinus patula trees

, 2003
Embryogenic cultures were initiated and established and somatic embryos produced in Pinus patula using thin sections from the dome of the vegetative shoot apex. Factors affecting initiation, basal medium and plant growth regulators were investigated.

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

Biological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Unexpected consequences of taxonomic misidentification for the conservation of an endangered species

Conservation Science and Practice, Volume 7, Issue 12, December 2025.
This article reports on the unexpected consequences of taxonomic misidentification of the endangered fir Abies hickelii in eastern Mexico. Misidentification led to positive outcomes, such as unintentional population increases through reforestation, but also negative outcomes, including logging and altered demographic structure.
