Growth in pure and mixed plantations of tree species used in reforesting rural areas of the humid region of Costa Rica, Central AmericaBackgroundDespite government incentives in Costa Rica for establishing and maintaining native tree plantations since the 1990s, farmers and small landowners often lack adequate knowledge about plantation management. Yield and rotation periods for each of the ten most common species grown in monoculture have previously been published. This paper compares productivity in monoculture and mixtures at La Selva Biological Station in the Caribbean lowlands of Costa Rica. Open access copy available |
Lattice-Work Corridors for Climate Change: A Conceptual Framework for Biodiversity Conservation and Social-Ecological Resilience in a Tropical Elevational GradientbackgroundIn the region of Monteverde, communities rely on ecotourism, coffee farming, dairy cattle farming and sugarcane production to making their livings. The Pacific-slope forests are highly fragmented, and while a large biological corridor has already been proposed, it neglects certain key riparian corridors that would facilitate species migrations and range shifts, as well as protect the downstream water sources.

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

Trade-offs in nature tourism: contrasting parcel-level decisions withlandscape conservation planningBackgroundA landscape approach to conservation has increasingly taken prominence as scientists and policymakers consider the role of landscape patches and connectivities. However, understanding trade-offs in policy decisions and land management strategies in a landscape dominated by privately held patches presents a challenge. This study discusses trade-offs with the nature tourism industry in Monteverde, Costa Rica, considering effects across parcel-level decisions. Open access copy available |
Sixty-Seven Years of Land-Use Change in Southern Costa RicaBackgroundHabitat loss and fragmentation of forests are among the biggest threats to biodiversity and associated ecosystem services in tropical landscapes. This paper uses the vicinity of the Las Cruces Biological Station in southern Costa Rica as a regional case study to comment on seven decades of land-use change in one of the most intensively studied sites in the Neotropics.

Neotropical Secondary Forest Succession: Changes in Structural and Functional CharacteristicsBackgroundThis paper reiviews the main biotic and abiotic factors that influence patterns of secondary forest succession in the Neotropics after complete forest clearance due to human activities. Research Goals & MethodsThe authors look at patterns of species replacement and various processes that occur during succession and suggest that the sequence of processes may be predictable even if species composition is not.

Testing Applied Nucleation as a Strategy to Facilitate Tropical Forest RecoveryBackgroundThis study considers applied nucleation, or the intensive planting of small patches of a mixture of successional species, as a degraded tropical forest restoration strategy. This approach catalyzes the natural regeneration of the surrounding matrix and larger landscape and could provide a less expensive alternative to the more common, and expensive, plantation-style approach. This study claims to be the first to directly compare tree recruitment beneath these two restoration approaches. Open access copy available |
Seed rain under tree islands planted to restore degraded lands in a tropical agricultural landscapeBackgroundPlanting native tree seedlings is the predominant restoration strategy for accelerating forest succession on degraded lands. However, planting tree “islands” is less costly and labor intensive than establishing larger plantations and simulates the nucleation process of succession. Tree islands can attract seed dispersers to gradually spread restoration patterns from the islands. Restoration design can be informed by assessing the effect of potential planting arrangements on seed dispersal by birds and bats and determining the influence of surrounding forest cover.

Effects of Dry Tropical Forest Fragmentation on the Reproductive Success and Genetic Structure of the tree Samanea samanbackgroundTropical trees are particularly vulnerable to forest fragmentation due to low population densities and reproductive self-incompatibility. Forest fragmentation is likely to decrease gene flow, increase endogamy, and eventually produce a high differentiation among remnant populations. Available with subscription or purchase |
Efecto de la zona de vida y la altitud en la mortalidad y adaptabilidad al primer año de especies forestales en la Cordillera Volcánica Central de Costa RicaEspañolAntecedentesEl entendimiento comprensivo de la restauración de bosques requiere de la comprensión del fenómeno de la mortalidad incluyendo su magnitud y ubicación espacial. En Costa Rica, no existe suficiente información capturando los efectos de climas pluviales sobre la mortalidad de especies forestales, especialmente en zonas altas. Open access copy available |
