Shaded-Coffee: A Nature-Based Strategy for Coffee Production Under Climate Change? A ReviewBackgroundCoffee agroforestry systems are a natural climate solution that are used to reduce the impact of coffee cultivation on ecosystem health. Coffee generates over $200 billion in income globally each year, so ensuring the efficiency and success of cultivation is crucial for human livelihood. Coffee agroforestry systems are often variable, and there lacks a compiled knowledge base about these systems and practices. Open access copy available |
Assisted restoration interventions drive functional recovery of tropical wet forest tree communitiesBackgroundIntegrating science and practice is one of the main goals of the U.N. Decade on Ecosystem Restoration. A variety of factors can influence the application of restoration treatments across tropical ecosystems. Deciding where to apply a restoration strategy on the spectrum between natural regeneration an active restoration planting can be challenging and there is not enough current knowledge that compares these methods.

Drought reduces the growth and health of tropical rainforest understory plantsBackgroundPlant responses to drought are important to understand for agricultural practices and environmental stress. Susceptibility to drought varies among and between plant species. Most field studies on plant responses to drought in tropical rainforests ignore understory plant species such as saplings and shrubs. These species are important to understand because they are often more vulnerable to environmental stressors, and they contribute greatly to forest biodiversity. Open access copy available |
Density-dependent reproductive success among sympatric dipterocarps during a major mast fruiting eventBackgroundMasting or mast fruiting is the annual synchronous production of many seeds by a plant species. Masting is an important reproductive strategy that depends on the intensity of flowering and fruiting, as well as the seeds’ ability to survive herbivory and competition with other seeds. Southeast Asia, many tree species (particularly Dipterocarps) are known to synchronize their masting events and therefore, community-wide seed density is an important factor predicting successful reproduction.

Overcoming biotic homogenization in ecological restorationBackgroundRegional, or gamma, diversity is often lower in restored landscapes compared to reference landscapes due to the selection of few desirable species for planting. Lowered diversity in restored landscapes is leading to overall biotic homogenization which puts ecosystems and humans in a more vulnerable position for adapting to environmental changes.

Genetic considerations in ecosystem restoration using native tree speciesIntroductionWith the rising interest on rehabilitation and restoration of forest landscapes to tackle climate change, there has been a renewed focus on the use of native species. Yet, the authors point out there is a lack of attention paid to genetic diversity among these trees along with their interactions, thus resulting in a failure to adequately assess the success of tree plantings.

Nitrogen-fixing trees inhibit growth of regenerating Costa Rican rainforestsBACKGROUNDNitrogen fixing plants are the primary source of nitrogen in forests, and it is expected that more nitrogen fixers will bring in faster growth. Hence this study conducted, in a humid tropical rainforest North- East Costa Rica, challenged this notion. The area of study had similar dominant species, with P. macroloba being the most dominant Nitrogen fixer. Open access copy available |

Microhabitats reduce animal’s exposure to climate extremesBackgroundThe Scheffers et al. (2014) paper discusses the effect of microhabitats and their corresponding microclimates on ectotherm species in a warming macroclimate. Available with subscription or purchase |
Asymmetric density dependence shapes species abundances in a tropical tree communityBackgroundThis study examined the question: why are some species common in tropical rainforests while others are rare? Goals & MethodsThe research, which used a computer modeling approach to analyze data from 20,000 1-meter squared plots, examined the degree to which being close to another individual of the same species affected the studied individual's overall abundance.
