Out of steady state: Tracking canopy gap dynamics across Brazilian Amazon

Background

Canopy gaps are a regular characteristic of natural or anthropogenic disturbance in forested landscapes. Gap-creating disturbances often result in a forest mosaic with patches of varying successional stages. Many species in tropical forests depend on these canopy gaps for regeneration. Field monitoring of canopy gaps can be difficult due to time constraints and plot size, making tropical gap dynamics an understudied topic.

Carbon-focused conservation may fail to protect the most biodiverse tropical forests

Introduction

The authors examine the relationship between carbon and biodiversity at the landscape-level across four gradients of disturbances and offer insight on optimizing carbon conservation projects with biodiversity conservation.

Restoration of Degraded Tropical Forest Landscapes

BACKGROUND

Forest loss and degradation negatively affect rural communities whose livelihoods are dependent on forests for ecological goods and services. To address the challenge, three solutions have been proposed, expanding networks of protected areas, improving agricultural productivity on abandoned lands and reforestation. Of the three, new approaches to restoration have shown to have the potential to address forest degradation and rural poverty.

Restoring forests as a means to many ends

BACKGROUND

The earth is nearly reaching environmental thresholds which can result in devastating effects of climate change and biodiversity loss. Failure to take action can lead to disruptions of ecosystems, economies, and the society. Protecting and restoring native ecosystems is needed, however, changes in forest cover have not been well understood. Also, the knowledge of where and how to focus such restoration efforts is still limited.

Environment and landscape rather than planting design are the drivers of success in long‐term restoration of riparian Atlantic forest

Introduction

While identifying factors that contribute to restoration is difficult, it is ultimately critical in order to ensure the long-term sustainability and resilience of the restored landscape.

Leverage points for improving global food security and the environment

BACKGROUND

Meeting global food demands is still a challenge, yet agriculture has been one of the main driving forces of greenhouse gas emissions. Hence, this study focused on identifying small regions, actions that can be taken and crops with a potential of increasing global yields, with an efficient system of food delivery and reducing the negative impacts of agriculture on the environment.

Anthropogenic disturbance in tropical forests can double biodiversity loss from deforestation

Background

The authors examined the impacts of anthropogenic disturbances within a forest on the ability of the forest to conserve biodiversity and provide ecosytem services. The research used large data sets of plants, birds, and dung beetles and used them as indicators of biodiversity change in the forest.

Targeted habitat restoration can reduce extinction rates in fragmented forests

Background

Habitat lost is one of the primary drivers of species extinction. This study examines two highly-fractured ecosystems, the Eastern Arc Mountains of Tanzania and the Atlantic Forest of Brazil, and evaluates the rate at which habitat loss may lead to extinction and thus biodiversity loss. Specifically, the authors use halflife vs. area relationship to determine how long it will take to lose one-half of all tropical bird communities in each habitat.

Variation in the population structure between a natural and a human-modified forest for a pioneer tropical tree species not restricted to large gaps

Background

The study evaluates the distribution of Cyperus floribundus (a long-lived pioneer tree specie) individuals in the gaps and compared the plant density between a primary and an early successional forest to understand the pioneer plant distribution and niche preference under the variable environmental and biotic conditions generated by natural or anthropogenic disturbances.
