Coffee Agroforests Remain Beneficial for Neotropical Bird Community Conservation across Seasons

Background

This study compares bird community composition in coffee agroforestry systems with secondary forest fragments, while accounting for seasonal bird migration and differences in bird detectability between habitats. It was conducted in the San Luis Valley of northwest Costa Rica, a montane forest region that encompasses many microhabitats.

Bird Perches Increase Forest Seeds on Puerto Rican Landslides

Background

Forest regeneration is typically difficult after landslides due to loss of above- and below-ground vegetative structure, the soil seed bank, soil nutrients, and soil structure. Landslides are a common occurrence in Puerto Rico due to its steep topography and heavy rainfall periods and often transform into grass- or fern-dominated terrain. Insufficient seed rain is thought to be one contributing factor.

Connecting sustainable agriculture and wildlife conservation: Does shade coffee provide habitat for mammals?

Background

Shade coffee systems are believed to support diverse wildlife. However, most research on wildlife in shade coffee has focused on bird and insect diversity, with few studies that have focused on mammals living within coffee-dominated landscapes.

Community Action for Biodiversity and Forest Conservation and Adaptation to Climate Change in the Wild Coffee Forests (CAFA)

Background

Located in southwest Ethiopia, the Kafa Biosphere Reserve is an important area for water quality, carbon storage, and a range of endangered and endemic species. Moreover, around 65,000 people live in the reserve, most of whom depend on subsistence agriculture for their livelihoods. Coffee also grows wild in the region, which locals often harvest for sale. Still, poverty and population growth is common within these communities, causing increasing strain on natural resources. To address these needs, Nabu began a community action project.

Carbon Footprint: Great Rift Valley, Kenya

BACKGROUND

This project takes place in the Kikuyu Escarpment, Western Kenya. The Kikuyu escarpment forest has a high biodiversity and the services the ecosystem provides, particular water, is a key source for neighboring communities' livelihoods. Environmental degradation through charcoal burning, logging for timber and fuel wood, ring-debarking for medicinal trees and overgrazing are negatively affecting these services and depleting the area of important vegetation cover.

Biodiversity–Productivity Relationships in Small-Scale Mixed-Species Plantations Using Native Species in Leyte Province, Philippines

background

The growth of tropical reforestation in recent decades has given rise to a debate between the relative productivity, biodiversity, and general merits of mixed-species vs. single-species plantations. To further investigate the relationship between tree species diversity, productivity, and abiotic factors such as climate and soil, this study investigated the growth of mixed-species plantations in Leyte province in the Philippines. These smallholder plantations were planted in 1992 to meet social, economic, and environmental needs through the Rainforestation Farming system.

Effects of Fragmentation of the Atlantic Forest on Mammal Communities in South-Eastern Brazil

Background

The author presents a detailed analysis of the community of large and medium-sized mammals present in six remnants of the low Atlantic forest in Brazil. The six remnants had varying sizes: small (200 ha), medium (2,000 ha) and large (20,000 ha). The study seeks to (1) identify the mammal species richness and the relative abundance of individuals surviving in each reserve, and (2) analyze changes in the structure of the mammal community contrasting the relative abundances of orders and dietary categories between reserves of differing sizes.

Vegetation Structure, Species Diversity, and Ecosystem Processes as Measures of Restoration Success

Background

This article provides an example of how to evaluate forest restoration using integrative methods, including measures of vegetation structure, species diversity, and ecosystem processes. Specifically discussed are four measures of vegetation structure, four measures of species diversity, and six measures of ecosystem processes.

Tropical rain forest fragmentation and its ecological and species diversity changes in Southern Yunnan

Background

Animal species richness is understood to decline with fragmentation of tropical forests. While the same is assumed of plant species richness, fewer studies have been undertaken on this subject. This study on sacred groves in southern Yunnan, southwestern China, evaluates the plant species richness of these tropical rainforest fragments.

Human Hydrographical Changes Interact with Propagule Predation Behaviour in Sri Lankan Mangrove Forests

Background

This article describes the relation between propagule predators and vegetation structure and environmental factors on a forest path. It also considers how human influence affects these interactions.
