Bioremediation has historically been approached as a 'black box' in terms of our fundamental understanding. Thus it succeeds and fails, seldom without a complete understanding of why. Systems biology is an integrated research approach to study complex biological systems, by investigating interactions and networks at the molecular, cellular, community, and ecosystem level. The knowledge of these...

Advances in cancer research have shown that a tumor can be likened to a foreign species that disrupts delicately balanced ecological interactions, compromising the survival of normal tissue ecosystems. In efforts to mitigate tumor expansion and metastasis, experimental approaches from ecology are becoming more frequently and successfully applied by researchers from diverse disciplines to revers...

Most studies that forecast the ecological consequences of climate change target a single species and a single life stage. Depending on climatic impacts on other life stages and on interacting species, however, the results from simple experiments may not translate into accurate predictions of future ecological change. Research needs to move beyond simple experimental studies and environmental en...

Understanding the impacts of species extinctions on the functioning of food webs is a challenging task because of the complexity of ecological interactions. We report the impacts of experimental species extinctions on the functioning of two food webs of freshwater and marine systems. We used a linear model to partition the variance among the multiple components of the diversity effect (linear g...

1. At the initial meeting of the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) of the Convention on Biological Diversity (CBD), it was recognised that “a holistic and not merely a conservation-oriented approach” was needed within the CBD. The second meeting of the Conference of Parties (COP) stated in decision II/8 that “...the conservation and sustainable use of bi...

Ecosystems can undergo sudden shifts to undesirable states, but recent studies with simple single-species ecosystems have demonstrated that advance warning can be provided by the slowing down of population dynamics near a tipping point. However, it is unclear how this 'critical slowing down' will manifest in ecosystems with strong interactions between their components. Here we probe the dynamic...

Globalization can have substantial impact on local commons by reducing sustainability of ecosystems and their vital services. Without effective local institutions, these resources are at high risk of exploitation, especially to feed global markets. This study proposes a multiscale ecosystem framework (MEF) that incorporates information on ecosystem components, socioeconomic processes, and their...

Ancient conceptualizations of ecosystems exist in several Amerindian, Asia-Pacific, European, and African cultures. The rediscovery by scientists of ecosystem-like concepts among traditional peoples has been important in the appreciation of traditional ecological knowledge among ecologists, anthropologists, and interdisciplinary scholars. Two key characteristics of these systems are that (a) th...

Shoot pruning of the woody components in simultaneous agroforestry systems with annuals and perennials enhances the services they provide to the ecosystem functions and to human livelihoods. These services include organic inputs, such as biomass and plant nutrients. Shoot pruning of the woody components is now an essential management practice in simultaneous agroforestry systems to avoid compet...

The eddy-covariance (EC) micro-meteorological technique and the ecology-based biometric methods (BM) are the primary methodologies to quantify CO2 exchange between terrestrial ecosystems and the atmosphere (net ecosystem production, NEP) and its two components, ecosystem respiration and gross primary production. Here we show that EC and BM provide different estimates of NEP, but comparable ecos...
