Perils and pleasures of multidisciplinary research
Over the past two decades various prestigious scientific and engineering organizations have touted the need for multidisciplinary research. Deans and department chairs often see multidisciplinary research as a potential pot of gold, and encourage faculty to follow the rainbow. Senior professors join in, seeking Enlightenment in their waning years, and young professors jump on board ...

Economists and ecologists: modelling global climate change to different conclusions
Numerous articles and studies have pointed to a divergence of opinion between economists and ecologists on environmental matters. This paper examines these differences as they apply to the debate over climate change. In particular, the paper examines the models that economists use for making decisions regarding climate change policy: cost–benefit analysis; utility theory; time-discounting; and ...

Methyl mercury and stable isotopes of nitrogen reveal that a terrestrial spider has a diet of emergent aquatic insects
Terrestrial spiders transfer methyl mercury (MeHg) to terrestrial consumers like birds but how spiders become contaminated with MeHg is not well understood. In the present study, we used stable isotopes of nitrogen in combination with MeHg to determine the source of MeHg to terrestrial long‐jawed orb weaver spiders (Tetragnatha sp). We collected spiders and a variety of other aquatic and ...

Personal carbon trading and sustainable consumption: the art of the state
Anticipating a new prominence for the carbon market and lifestyle change in post-2012 implementation of ambitious carbon mitigation targets in OECD countries, including the UK, this paper draws on Foucauldian scholarship to support an argument that personal carbon trading (PCT) may be consistent with New Labour's understanding of the role of the 'consumer citizen' in modern Britain, and that PCT ...

Modeling vital rates improves estimation of population projection matrices
Population projection matrices are commonly used by ecologists and managers to analyze the dynamics of stage-structured populations. Building projection matrices from data requires estimating transition rates among stages, a task that often entails estimating many parameters with few data. Consequently, large sampling variability in the estimated transition rates increases the uncertainty in the ...

Interdisciplinary research at the Urban–Rural interface: The West ga project
As human populations increase, ecological and social issues become inextricably linked to a greater degree. Solutions to complex social–ecological problems can only be derived through the use of integrated research that can account for the interplay of many factors across traditional discipline lines. We are using such an integrated research to clarify relationships among socioeconomic drivers, ...

An ecologist's view of economic instruments and incentives
Advice by fisheries scientists to reduce catches or effort is often not fully implemented and efforts to increase impact of advice have often failed. Fisheries scientists rarely discuss the potential contribution of economic instruments to improving the impact of science advice. This paper rejects several possible justifications for the absence of discussion on economic instruments in fisheries ...

Modeling Phosphorus in the lake Allatoona watershed using swat: I. developing Phosphorus parameter values
Lake Allatoona is a large reservoir north of Atlanta, GA, that drains an area of about 2870 km2 scheduled for a phosphorus (P) total maximum daily load (TMDL). The Soil and Water Assessment Tool (SWAT) model has been widely used for watershed-scale modeling of P, but there is little guidance on how to estimate P-related parameters, especially those related to in-stream P processes. In this paper, ...

Needed: A copernican shift
In 1543, Polish astronomer Nicolaus Copernicus published “On the Revolutions of the Celestial Spheres,” in which he challenged the view that the sun revolved around the earth, arguing instead that the earth revolved around the sun. With his new model of the solar system, he began a wide-ranging debate among scientists, theologians, and others. His alternative to the earlier Ptolemaic model, which ...

Significance of Landscape Age, Uplift, and Weathering Rates to Ecosystem Development
The combined roles of chemical and physical weathering have profound effects on the development of terrestrial ecosystems. Landscapes which are tectonically active are rapidly denudated and continually produce nutrient solutes from fresh bedrock. The chemical weathering yields are related to climate, but also to geologic factors such as uplift rates. Long-term nutrient production and the phase of ...

Use of the ecosystem services concept in ecological risk assessment of chemicals
Abstract ‐ The reason for expressing ecological protection goals in terms of ecosystem services is to make a connection between ecosystems and what people get out of them in terms of marketed goods and non‐marketed welfare. Here our focus will be on how the ecosystem services framework is and can be applied to the ecological risk assessment (ERA) of chemicals. We provide two contrasting ...

Ecologists pay disproportionately little attention to synthetic chemicals, study finds
Manmade chemicals may alter ecological processes, yet few scientists are studying the role of these chemicals in global environmental change, say a group of researchers from the U.S. and Germany in a scientific paper published today in the journal Frontiers in Ecology and the Environment. In recent decades, humans have increased production of chemicals faster than we’ve made other changes ...

Biosecurity from the ecologist's perspective: developing a more comprehensive approach
National planning for biological security should encompass more than just protection against biological weapons. Global forces such as the introduction and spread of invasive species (including emerging infectious diseases), in conjunction with population growth, climate change and sea-level rise, also constitute threats to security. These linked biological and abiotic phenomena make the United ...

Can big data save the last of India’s wild tigers?
Analyzing 25,000 individual observations, wildlife managers find clues to help stop poachers in their tracks. Traveling in small, nomadic groups, carrying knives, axes and steel traps, tiger poachers in India have long held advantages over those trying to protect the big cats. The poachers, motivated mainly by demand for tiger bones used in traditional medicine in China, return every two to ...

A case study of some lakes located at and around Thane City of Maharashtra, India, with special reference to physico-chemical properties and heavy metal content of lake water
The increasing trend in concentration of metals in the environment has created considerable attention amongst ecologists globally during the last decades. However, no such studies have been carried out in India and there are no past metal load data available. Therefore, we initiated a study to estimate the levels of water pollution of the Upavan, Masunda, Makhmali and Rewale Lakes situated at ...

Bridging the gap between micro - and macro-scale perspectives on the role of microbial communities in global change ecology
Abstract In order to understand the role microbial communities play in mediating ecosystem response to disturbances it is essential to address the methodological and conceptual gap that exists between micro- and macro-scale perspectives in ecology. While there is little doubt microorganisms play a central role in ecosystem functioning and therefore in ecosystem response to global ...
