The Swiss watchmaker Rolex has just announced that University of Kent PhD student Laury Cullen Jr has won a Rolex Award for Enterprise 2004. view more (2004-10-18)
Conservation in Canada
Conservation actions could be more efficient if there is similarity among taxa in the distribution of species. In a paper in Ecology Letters, May, by an international research team, patterns in the geographic distribution of five taxa were used to identify nationally important regions for conservation in Canada. There was congruence in both... view more... (2004-05-04)
Marine Reserves Have Rapid and Lasting Effects - Benjamin S. Halpern & Robert R. Warner in ECOLOGY LETTERS
Marine reserves have rapid and lasting impacts on organisms inside reserves, according to scientists at the University of California, Santa Barbara. In a paper published in the current issue of ECOLOGY LETTERS, the researchers reviewed 80 studies from `no-take` reserves, where it is illegal to extract organisms in any way. These showed that... view more... (2002-05-21)
University of Sussex launches world's first degree programme in 'seed banking'
Biologists are being offered the chance to help save the planet by enrolling in an innovative new postgraduate degree at the University of Sussex this autumn. Together with the world-renowned Royal Botanic Gardens, Kew, the University is to offer the world's first degree programme in 'seed banking', which includes strategies for safeguarding the... view more...

First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
The first "State of the Carbon Cycle Report" for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. view more (2007-11-15)
The effect of transgenic nematode resistance on non-target organisms in the potato rhizosphere
A paper published today in the December Issue of Journal of Applied Ecology by Cowgill et al describes the results of small-scale field trials that were used to assess the effect of PI-expressing potatoes on non-target soil organisms. The impact of a currently used PCN management option, the nematicide, aldicarb, on soil organisms was also studied. view more (2002-11-26)
Slowing insect resistance to genetically modified crops
Genetically modified Bt crops are now widely used in the USA. These crops contain genes from bacteria that make them toxic to some insect pests. A central concern in regulating these genetically modified crops is the risk of insects evolving resistance to the Bt toxins. To reduce this risk, the "high dose/refuge" strategy is now being used, in... view more... (2002-10-30)
Invasive plant outcompeted by its native ancestors
Invasive alien species are one of the greatest threats to global biodiversity. Part of their success may be due to rapid evolutionary changes when invaders adapt to the novel conditions in their invaded habitats. Invasive plants, in particular, are believed to double-profit from a loss of their natural enemies and subsequent evolution of less... view more... (2004-03-18)
Antarctic icebergs: unlikely oases for ocean life
Icebergs have long gripped the popular imagination, whether as relatively run-of-the-mill floating hazards that cause "unsinkable' ships to founder or, more recently, as enormous breakaway pieces of ice the size of states or small countries. view more (2007-06-25)
Why does species diversity vary so much?
The diversity of life varies predictably with climate and is greatest where it is warm and wet (the humid tropics). But the question "why" has puzzled biologists for over a century. In the December issue of Ecology Letters, Currie and colleagues examine three hypotheses about the origin of climatic gradients of diversity. The... view more... (2005-01-11)
When fish become extinct, the cycling of critical nutrients in ecosystems changes, Cornell study finds
Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out. view more (2007-03-05)
Nutrients cause increase in parasites and frog deformities
Extra and missing-legged frogs have become increasingly common in North American wetlands over the last decade. Research implicates a flatworm parasite, Ribeiroia ondatrae, as the culprit of these deformities. Reasons for the apparent increase in infection and malformations, however, have remained a mystery. In the July issue of Ecology Letters,... view more... (2004-06-10)
Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
The biodiversity of a community can affect its functional properties, such as its productiveness or its ability to resist invasion by exotic species. Many grass species host fungi in their leaves that can render them more resistant to herbivory, drought, and competition. In a forthcoming issue of Ecology Letters, Rudgers, Koslow and Clay... view more... (2003-12-10)
Bright autumn colouration in trees - a warning signal to insects?
Most deciduous trees change colour in autumn. However, both within and between species, there is considerable variation both in the timing and magnitude of autumn colour change. Hamilton and Brown recently proposed a hypothesis to explain this phenomenon. Their idea was that the bright autumn colouration in trees is a warning signal to insects... view more... (2003-09-17)
Soil fungi affect parasitism of foliage-feeding insects
Recent studies have shown the importance of links between soil organisms and those feeding above-ground. However, to date these have involved two or three trophic levels, because it has been assumed that the effects weaken as one progresses up or down a food chain. In a forthcoming paper in Ecology Letters, Gange, Brown & Aplin show that... view more... (2003-11-24)
DNA research flies high with Seychelles kestrel
A new research project at the University of Kent is looking for genetic evidence of a historical population bottleneck in the Seychelles kestrel by analysing DNA extracted from museum specimens estimated to be 100-150 years old. Dr Jim Groombridge, Lecturer in Biodiversity Conservation at the University's Durrell Institute of Conservation and... view more... (2004-06-01)
EU-project strengthens monitoring the impact of climate change on nature
On March 1 the European Phenology Network (EPN) - a network to increase the use of phenological data and to stimulate monitoring and research in Europe in the context of climate change - will officially be launched during the first project meeting at Wageningen University, the Netherlands. The EPN-project has been funded for three years... view more... (2001-02-27)
Ecosystem consequences of a single, genetically based plant trait
Climate is often touted as the most important regulator of decomposition and nutrient cycling processes in forest ecosystems, however, in the forthcoming issue of Ecology Letters, Schweitzer and her research team from Northern Arizona University and the University of Wisconsin, USA, demonstrate that plant genes can have strong effects on the... view more...

Biodiversity conservation - no guarantee for shortcuts
New research from scientists at the University of Sheffield published in the November issue of Ecology Letters has cast doubts on the widely held `rule of thumb` that the conservation of a country`s biodiversity can be guaranteed by focusing on protecting its threatened and endemic species. In a report published this week, Aletta Bonn, Ana... view more... (2002-10-30)
The emerging scientific discipline of aeroecology
In the history of science and technology, there is an infrequent combination of empirical discoveries, theories and technology developments converge that make it possible to recognize a new discipline. view more (2008-08-04)
