Bioremediation of a crude-oil polluted agricultural-soil at Port Harcourt, Nigeria

Background

Since more than 98% of Nigeria’s current economic support is crude oil, and oil spills are in inevitable and frequent, six treatment sample-cell were tested on the soils of the Niger Delta of Nigeria for crude oil bioremediation. Oil spills cause nitrogen levels to decrease, while increasing carbon content. A decrease in nitrogen and the toxicity of crude oil reduces the growth of heterotrophic bacteria, which utilize petroleum carbon for cell synthesis.

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.

Impact of Forest Management on Insect Abundance and Damage in a Lowland Tropical Forest in Southern Cameroon

Background

A burgeoning timber industry in Cameroon, which became the fifth largest producer of timber in the world in the 1990’s, led to unsustainably high deforestation rates and high demand for forest regeneration interventions. Research in the Mbalmayo Forest Reserve in southern Cameroon has compared different silvicultural techniques for forest regeneration including complete and partial clearance methods.

Nitrogen-fixing trees inhibit growth of regenerating Costa Rican rainforests

BACKGROUND

Nitrogen 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.

Multiple successional pathways in human-modified tropical landscapes: new insights from forest succession, forest fragmentation and landscape ecology research

Introduction

With the rise of deforestation, secondary forests and human-modified tropical landscapes (HMTL) have become an important source of ecosystem services yet there is limited knowledge concerning the successional process of these ecosystems.

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.

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.

Carbon colonialism and the new land grab: Plantation forestry in Uganda and its livelihood impact

Background

There has been a global increase in private sector investments towards activities plantations for clean fuel or climate change mitigation that are justified on the basis of their environmentally beneficial outcomes. This paper examines the discourses and mechanisms that enable the greater privatization of land and other resources using green development as a justification.

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.
