The most unique feature of Earth is the existence of life, and the most extraordinary feature of life is its diversity. Approximately 9 million types of plants, animals, protists and fungi inhabit the Earth. So, too, do 7 billion people. Two decades ago, at the first Earth Summit, the vast majority of the world’s nations declared that human actions were dismantling the Earth’s ecosystems, eliminating genes, species and biological traits at an alarming rate. This observation led to the question…

One of the greatest attributes of the Earth is the biodiversity of her ecosystem, but the last few decades, have witnessed a rapid disruption and loss of this rich biodiversity in terms of numbers and variability.

There are different meanings of the term “Biodiversity”. The 1992 United Nations Earth Summit characterized “Natural Diversity” as “the fluctuation among living beings from all sources, including,

The co-evolution of life and biogeochemical cycles in our planet

Abstract The Earth has undergone numerous geological and biological changes over billions of years. The evolution of plants and animals had a direct relationship with the elements’ changes in the

Tropical Biodiversity: The Importance of Biotic Interactions for Its Origin, Maintenance, Function, and Conservation

Most of the Earth’s terrestrial biodiversity is found in tropical forests, a fact that fascinates us today as it did the early naturalists of past centuries. It is in this biome where a tremendously

A century of biodiversity: some open questions and some answers

The study the biodiversity is not just an attempt to understand the differences or similarities between species, habitats or genomes. It also includes an understanding of how nature regulates the

Effects of climate change on biodiversity and measures for them

In this study, formation background of biodiversity and its changes in the process of geologic history, and effects of climate change on biodiversity and human were discussed and the alternatives to

Why biodiversity has so many enemies

By including invertebrate and microbial organisms in mainstream conservation science and policy, several profound benefits accrue and it is in the self-interest of the biodiversity-based industries to protect their resources and to identify biodiversity conservation as core business.

The contemporary view of biodiversity: bad science and bad policy

Biodiversity conservation science and policy largely ignores the majority of species: the microbes and invertebrates. This biodiversity contains most genetic, metabolic and chemical diversity on

Biodiversity, or biological diversity, is the variety of all species on earth. It is the different plants, animals and micro-organisms, their genes, and the terrestrial, marine and freshwater

The role of biodiversity in integrated landscape approaches

Global biodiversity loss is a major challenge. Since 1970, the number of birds, mammals, reptiles and amphibians has dropped by more than half and over a quarter of all species (one million animal




Understanding this complexity, while taking strong steps to minimize current losses of species, is necessary for responsible management of Earth's ecosystems and the diverse biota they contain.

Declining biodiversity can alter the performance of ecosystems

COMMUNITIES of species and their associated biological, chemical and physical processes, collectively known as ecosystems, drive the Earth's biogeochemical processes1,2. Currently most ecosystems are

Trophic Downgrading of Planet Earth

This empirical work supports long-standing theory about the role of top-down forcing in ecosystems but also highlights the unanticipated impacts of trophic cascades on processes as diverse as the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles.

The functional role of producer diversity in ecosystems.

Several new questions must now be addressed if this field is going to evolve into a predictive science that can help conserve and manage ecological processes in ecosystems, including questions about how primary producer diversity influences the efficiency of resource use and biomass production in ecosystems.

Evolutionary history and the effect of biodiversity on plant productivity

It is shown that the amount of phylogenetic diversity within communities explained significantly more variation in plant community biomass than other measures of diversity, such as the number of species or functional groups.

Biodiversity and stability in grasslands

ONE of the ecological tenets justifying conservation of biodiversity is that diversity begets stability. Impacts of biodiversity on population dynamics and ecosystem functioning have long been

Preserving the Tree of Life

Phylogenies provide new ways to measure biodiversity, to assess conservation priorities, and to quantify the evolutionary history in any set of species, including ways to prioritize outcomes from evolutionary and ecological processes.

Organisms as ecosystem engineers

The role that many organisms play in the creation, modification and maintenance of habitats does not involve direct trophic interactions between species, but they are nevertheless important and common.

Effects of biodiversity on the functioning of trophic groups and ecosystems

A formal meta-analysis of studies that have experimentally manipulated species diversity to examine how it affects the functioning of numerous trophic groups in multiple types of ecosystem suggests that the average effect of decreasing species richness is to decrease the abundance or biomass of the focal Trophic group, leading to less complete depletion of resources used by that group.

Impacts of biodiversity on the emergence and transmission of infectious diseases

Overall, despite many remaining questions, current evidence indicates that preserving intact ecosystems and their endemic biodiversity should generally reduce the prevalence of infectious diseases.
