Introduced marine species get larger in the invaded region
The transport of species outside their native region through human activities has often had a dramatic impact on the ecosystems into which these species are introduced and on the surrounding economies. The consequences of introduction for the introduced species itself, including changes in body size and shape, are less recognized. Prior studies of most groups of organisms, including plants,...

All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon species. In the June issue of Ecology Letters, Smith and Knapp show that with a more realistic... View News Article (2003-05-22)

Biocontrol research on Brazilian peppertree in Florida discovers new cryptic species
Dr Michael Pogue, a Research Entomologist in the ARS Systematic Entomology Laboratory, at the Smithsonian Institution, Washington, DC, was sent a series of moth specimens from Bahia, Brazil, for identification. The insects were under consideration as a possible biocontrol agent for the invasive Brazilian peppertree in Florida. View News Article (2013-02-07)

Three new species of lemurs identified
Researchers have identified three new species of lemurs, the small, big-eyed primates native to the island of Madagascar. View News Article (2006-02-23)

Evolution of new species slows down as number of competitors increases
The rate at which new species are formed in a group of closely related animals decreases as the total number of different species in that group goes up, according to new research published in PLoS Biology. View News Article (2008-03-25)

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 Rodrigues and Kevin Gaston explain, "Nationally... View News Article (2002-10-30)

Limited climate tracking in European trees despite 10,000 years of postglacial warmth
The relative roles of environment and history as controls of large-scale species distributions is a crucial issue in biogeography and macroecology. In the forthcoming issue of Ecology Letters Svenning & Skov use bioclimatic modelling to show that among 55 native European tree species, 36 occupy less than 50% of their climatically suitable range. Many of these species naturalize extensively... View News Article (2004-06-10)

Competition between species curbs selfishness?
Animals are in constant competition over procreative resources. The interests of the individual and the population are not necessarily one and the same; aggressive insects may fare well in the mating competition, but eventually the proliferation of aggressive genes will weaken the procreative efficiency of the species. View News Article (2004-12-20)

Between geometry and biology: How and why does the number of species depend on area
There are few universal rules in ecology, but arguably one is the relationship between the area of a study plot and the number of species counted within that plot, the so called species-area relationship. View News Article (2011-11-11)

Cryptic worms encountered outside Sweden
Polychaete worms have populated the oceans for millions of years. Today they are the focus of study on cryptic species, which shows that apparently identical animals may be entirely different species. View News Article (2010-06-14)
