Are the native giant tortoises from the Seychelles really extinct? A genetic perspective based on mtDNA and microsatellite data.
(Mol Ecol, 2003-06)The extinction of the giant tortoises of the Seychelles Archipelago has long been suspected but is not beyond doubt. A recent morphological study of the giant tortoises of the western Indian Ocean concluded that specimens ... -
Eco-evolutionary feedbacks in community and ecosystem ecology: interactions between the ecological theatre and the evolutionary play.
(Philos Trans R Soc Lond B Biol Sci, 2009-06-12)Interactions between natural selection and environmental change are well recognized and sit at the core of ecology and evolutionary biology. Reciprocal interactions between ecology and evolution, eco-evolutionary feedbacks, ... -
Eco-evolutionary trophic dynamics: loss of top predators drives trophic evolution and ecology of prey.
(PLoS One, 2011-04-19)Ecosystems are being altered on a global scale by the extirpation of top predators. The ecological effects of predator removal have been investigated widely; however, predator removal can also change natural selection acting ... -
Experimental evaluation of evolution and coevolution as agents of ecosystem change in Trinidadian streams.
(Philos Trans R Soc Lond B Biol Sci, 2009-06-12)Evolution has been shown to be a critical determinant of ecological processes in some systems, but its importance relative to traditional ecological effects is not well known. In addition, almost nothing is known about the ... -
Experimental evidence that phenotypic divergence in predators drives community divergence in prey.
(Ecology, 2009-02)Studies of adaptive divergence have traditionally focused on the ecological causes of trait diversification, while the ecological consequences of phenotypic divergence remain relatively unexplored. Divergence in predator ... -
Fates beyond traits: ecological consequences of human-induced trait change
(Evolutionary Applications, 2012) -
From genes to ecosystems: an emerging synthesis of eco-evolutionary dynamics
(New Phytol, 2009) -
Genetic evaluation of a proposed introduction: the case of the greater prairie chicken and the extinct heath hen.
(Mol Ecol, 2004-07)Population introduction is an important tool for ecosystem restoration. However, before introductions should be conducted, it is important to evaluate the genetic, phenotypic and ecological suitability of possible replacement ... -
Independent evolutionary origins of landlocked alewife populations and rapid parallel evolution of phenotypic traits.
(Mol Ecol, 2008-01)Alewife, Alosa pseudoharengus, populations occur in two discrete life-history variants, an anadromous form and a landlocked (freshwater resident) form. Landlocked populations display a consistent pattern of life-history ... -
Intraspecific variation in a predator affects community structure and cascading trophic interactions.
(Ecology, 2008-07)Intraspecific phenotypic variation in ecologically important traits is widespread and important for evolutionary processes, but its effects on community and ecosystem processes are poorly understood. We use life history ... -
Some cautionary notes on fisheries evolutionary impact assessments.
(Proc Natl Acad Sci U S A, 2009-10-13) -
The evolutionary origin of Indian Ocean tortoises (Dipsochelys).
(Mol Phylogenet Evol, 2002-08)Today, the only surviving wild population of giant tortoises in the Indian Ocean occurs on the island of Aldabra. However, giant tortoises once inhabited islands throughout the western Indian Ocean. Madagascar, Africa, and ... -
The overfishing debate: an eco-evolutionary perspective.
(Trends Ecol Evol, 2011-12) -
Working at the interface of phylogenetics and population genetics: a biogeographical analysis of Triaenops spp. (Chiroptera: Hipposideridae).
(Mol Ecol, 2007-02)New applications of genetic data to questions of historical biogeography have revolutionized our understanding of how organisms have come to occupy their present distributions. Phylogenetic methods in combination with divergence ...
