Summary: Restoring degraded dryland requires a diverse mixture of trees and shrubs. Shading and species diversity can improve seedling survival and vitality. Shaded conditions led to higher seedling survival, vitality, and chlorophyll content, while increasing species richness improved seedling vitality in non-shaded conditions.

Summary: This study investigates the indigenous knowledge of the Gurage people in Ethiopia regarding the cultivation and consumption of the enset plant, as well as its economic, cultural, and symbolic value. The findings suggest that enset plays a significant role in socialization and is a factor in wealth stratification.

Summary: Dry forests are under threat and often converted into agricultural landscapes, but farmers in Yucatan, Mexico retain trees and palms within their grazing pastures. A study found that native dry forest tree species are conserved in the pastures, with palms being the most abundant. Palms and trees positively affect grasses in pastures during droughts but slow down their recovery during the wet season.

Summary: This study examines the social dynamics of urban tree planting, focusing on the African plum tree in Yaounde, Central Africa. The research reveals that urban trees in Yaounde have a high level of genetic diversity similar to that of the species' production region. The findings suggest that cities and urban dwellers can play a role in safeguarding indigenous tree genetic diversity.

Summary: This study aimed to enhance our understanding of the impacts of alien species on native freshwater megafauna. The research found that 61 alien species caused negative impacts on 44 native freshwater megafauna species, with predation and competition being the most common mechanisms. It is worth noting that data limitations and the complexity of multiple threats make it difficult to fully assess the significance of alien species impacts.

Summary: During an investigation of fungal diversity on fruit trees in Guizhou Province, 23 Cladosporium strains were isolated and characterized using culture characteristics, morphology, and molecular phylogenetic analysis. This study identified seven new Cladosporium species and introduced new host records for five other species, highlighting the rich diversity of Cladosporium spp. in fruit trees in Guizhou Province.

Summary: Sustainable cities rely on urban forests, with city trees playing a crucial role in improving health, air quality, and temperature regulation. However, little is known about urban tree communities as ecosystems, especially in terms of their spatial composition, species diversity, and the impact of introduced species. This study collected and analyzed data on over 5.6 million trees from 63 major US cities, revealing that trees tend to cluster by species and introduced species homogenize tree communities across cities. The study also found that native trees make up a significant portion of city tree populations and that climate influences tree species diversity in urban forests. These findings highlight the importance of analyzing spatial composition and introduced species in urban ecosystems and provide tools for future research in this area.

Summary: Invasive apple snails have negative impacts on non-native habitats and human well-being. This study compares the trophic position of Pomacea canaliculata in native habitats (Maldonado, Uruguay) and non-native habitats (Hangzhou, China and Hawaii, USA). It was found that species evenness is correlated with apple snail trophic level, and there are two subsets of apple snail trophic-level data: a biodiverse subset and a homogenized subset.

Summary: In this study, 30 endophytic Trichoderma isolates obtained from wild Hevea spp. in the Brazilian Amazon were analyzed. The analysis revealed known Trichoderma species as well as four new species. This study contributes to our understanding of the diversity of endophytic Trichoderma species in Neotropical forests and identifies potential biocontrol agents for plant disease management.

Summary: In this study, newly discovered evolutionarily significant populations of Korogwe tilapia from southern Tanzania are threatened by hybridization with invasive Nile tilapia. Genetic analysis shows distinct differences between southern and northern populations of O. korogwe, with evidence of hybrids in southern lakes. This highlights the need for conservation interventions to protect these unique genetic resources.

Summary: Climate change is identified as one of the main drivers of species extinction in the 21st century. Using different climate change scenarios, a study conducted in Brazil showed that the bioclimatic area of habitat for potential agroforestry species is projected to decline in the future, leading to a potential loss of habitat for these species. However, only a small percentage of the studied species are currently at risk based on the IUCN criteria. To mitigate these threats, promoting the use of these species in rural and peri-urban agroecosystems is suggested as a promising strategy for their long-term conservation.

Summary: Non-native species can have significant negative impacts on the environment, economies, and human well-being. The number of newly recorded non-native species in the European Union has been increasing due to globalization and economic incentives, however, there has been a recent decrease in reporting. Despite this, the ecological and economic burden of non-native species persists.

Summary: The study compares the native bee community and plant-bee interaction networks in old growth, naturally regenerating, and actively managed mature secondary growth forests. The results show that old growth forests have higher bee species richness and Shannon's diversity index compared to actively managed and naturally regenerating mature secondary forests. Forest type has a significant effect on bee community composition, and clear-cutting may have long-term negative effects on bee biodiversity in mature secondary growth forests.

Summary: In the Mediterranean basin, agriculture and human land use have had a significant impact on the environment for centuries. Despite the prevalence of modern agricultural systems, ancient varieties of fruit trees have survived in less intensively managed rural areas. This study in southern Italy identified some of the oldest scientifically dated fruit trees in the world and highlighted their importance for genetic preservation and biodiversity conservation.
