Forest Dynamics

Old timber plantations and secondary forests attain levels of plant diversity and structure similar to primary forests in the West African humid tropics

Background

There is a high rate of biodiversity loss and deforestation in tropical ecosystems. In order to maintain global biodiversity, it is necessary to conserve plant diversity in alternative forest landscapes such as secondary forests and plantations. Comparing conservation values and tradeoffs of different forest landscapes is important for sustainable forest management and conservation practices.

Linking disturbance history to current forest structure to assess the impact of disturbances in tropical dry forests

Background

Tropical dry forests are given less attention in studies compared to tropical humid forests, but they still experience high levels of disturbance, both natural and human-made. These disturbances heavily alter the characteristics of valuable remaining forest structures. There are gaps in knowledge about how the timing and type of disturbance affects forest structure in seasonally dry tropical forests.

Forest ecosystem services at landscape level – Why forest transition matters?

Background

Forest transition theory describes patterns of forest decline and recovery. This theory explains what services change as forested landscapes shift in the three stages of recovery. This model covers both forest-type gradients (diversity and usage) and landscape gradients (connectivity and coverage). It is not yet understood how these forest transition stages influence the quantity and quality of ecosystem services.

Multiple invasions exert combined magnified effects on native plants, soil nutrients and alters the plant-herbivore interaction in dry tropical forest

Background

Globalization has resulted in a higher number of species invasions, which have had detrimental impacts on ecosystem biodiversity, functions, and services. Assessment and management of all invasive species is based on knowledge of a small number of species. Management is also focused on single-species invasions rather than multiple simultaneous invasions. India has a high level of species invasions and minimal resources to control them.

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.

Legacy effects of canopy gaps on liana abundance 25 years later in a seasonal tropical evergreen forest in northeastern Thailand

Background

Lianas or woody vine species are abundant in tropical forests. They depend on trees for stability to grow and climb to the canopy. While lianas depend on trees for growth, they also require canopy gaps at early growing stages to satisfy their high demand for sunlight. At times, lianas occupy new treefall gaps densely enough to prevent tree regeneration. Tree host ability may influence the abundance of lianas in Southeast Asian seasonally dry tropical forests.

Mangroves of Kenya: The effects of species richness on growth and ecosystem functions of restored East African Mangrove stands

Background

The authors of the story identify the gaps in long-term studies on the relationship between species diversity and ecosystem services in specific ecosystems. The study focuses on one of these ecosystems: mangroves, examining the effects of species diversity on above ground productivity.

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.

Restoration of plant species and genetic diversity depends on landscape‐scale dispersal

Introduction

The article cites the importance of restoration efforts that leads to resilient, self-sustaining ecosystems in order to combat immense global change. Though biological and species diversity are key to this venture, they are rarely considered a factor. Thus, this review article highlights the connection between seed dispersal and species richness and diversity to landscape restoration.

Forests, atmospheric water and an uncertain future: the new biology of the global water cycle

Introduction 

This article provides a review of the connection between vegetation cover and climate, with a specifical focus on forests and rain. The author details how there are shortcomings in knowledge concerning how tree cover influences water-cycles, which are both highly complex and important. In order to direct readers to potential research opportunities in this field, the article highIights advances and uncertainties in this field through reviewing it's major research themes.
