The Complex Genetic Legacy of Hybridization and Introgression between the Rare ...

Hybridization and introgression are complex evolutionary mechanisms that can increase species diversity and lead to speciation, but may also lead to species extinction. In this study, we tested the presence and genetic consequences of hybridization between the rare and Ecuadorian endemic O. loxensis van der Werff and the widespread O. infrafoveolata van der Werff (Lauraceae). Phenotypically, some trees are diff...

The case of a threatened medicinal tree with optimistic prospects under climate...

Climate change is an increasing cause of biodiversity loss. The extinction of species is the most dramatic case, but also a large number of species will be forced to migrate due to the loss of habitat. We conducted a study on the current distribution of Warburgia salutaris (Canellaceae), one of the wild harvested medicinal plant species endangered through the effects of bark harvesting and land transformation, ...

Impact of climate changes in the suitable areas for Coffea arabica L. productio...

Climate changes (CC) are a main global phenomenon, with a worldwide impact on natural and agricultural ecosystems. The objective of this study was to analyse the potential impact of future CC on the suitability of areas for rainfed coffee growth, both at the Mozambique national scale and in the Gorongosa Mountain, under Agroforestry (AFS) and Full Sun (FS) management systems. The latter study site is part of th...

Genetic diversity and structure in two epiphytic orchids from the montane fores...

Ecuador has a high diversity of orchids, but little is known about levels of genetic diversity for the great majority of species. Understanding how orchids might adapt to changes is crucial as deforestation and fragmentation of forest ecosystems threaten the survival of many epiphytic orchids that depend on other species, such as fungi and their host trees, for germination, growth, and establishment. Overcollec...

Editorial: Overcoming the Global Climate Crisis: Solutions to Minimize the Loss...

Mediterranean-climate regions are home to significant levels of plant diversity and endemism that are challenged by the threats of the modern world: habitat loss and fragmentation, high human population growth, and overexploitation of natural resources. Because of the fast rate of changes occurring in its ecosystems, many plants are threatened, and the trend is to worsen throughout the century (Muñoz-Rodríguez ...

Early Signs of the Effects of Forest Fragmentation on the Genetic Diversity and...

The diversity of genetic resources is essential to cope with environmental changes. However, despite forests play a crucial role in mitigating changes, genetic knowledge has scarcely been used for forest conservation. In this study, we used nuclear microsatellites to understand the patterns of genetic diversity and population genetic structure in Ocotea rotundata van der Werff (Lauraceae), an endemic Ecuadorian...

Untapping the Potential of Neglected and Underutilized Species to Improve Food ...

Diversity of Cowpea [Vigna unguiculata (L.) Walp] Landraces in Mozambique: New ...

Cowpea (Vigna unguiculata) is a neglected crop native to Africa, with an outstanding potential to contribute to the major challenges in food and nutrition security, as well as in agricultural sustainability. Two major issues regarding cowpea research have been highlighted in recent years—the establishment of core collections and the characterization of landraces—as crucial to the implementation of environmental...
