Evolving eco-system: a network of networks [PDF]

, 2004
Ecology and evolution are inseparable. Motivated by some recent experiments, we have developed models of evolutionary ecology from the perspective of dynamic networks.

Network analysis identifies weak and strong links in a metapopulation system [PDF]

, 2008
The identification of key populations shaping the structure and connectivity of metapopulation systems is a major challenge in population ecology. The use of molecular markers in the theoretical framework of population genetics has allowed great advances

Density but not climate affects the population growth rate of guanacos (Lama guanicoe) (Artiodactyla, Camelidae) [v2; ref status: indexed, http://f1000r.es/3h1]

F1000Research, 2014
We analyzed the effects of population density and climatic variables on the rate of population growth in the guanaco (Lama guanicoe), a wild camelid species in South America.

Population ecology of the sea lamprey (Petromyzon marinus) as an invasive species in the Laurentian Great Lakes and an imperiled species in Europe

Reviews in Fish Biology and Fisheries, 2016
The sea lamprey Petromyzon marinus (Linnaeus) is both an invasive non-native species in the Laurentian Great Lakes of North America and an imperiled species in much of its native range in North America and Europe.

Demography of Attalea nucifera: sustainable management and conservation of a threatened species of Colombia

Caldasia, 2020
Attalea nucifera is an acaulescent palm native of Colombia that is in risk of extinction. Between 2016-2017 we evaluated the structure and density of populations in six localities of the Magdalena river val-ley, and studied the population dynamic in the ...

Fine-scale population structure and asymmetrical dispersal in an obligate salt-marsh passerine, the Saltmarsh Sparrow (Ammodramus Caudacutus) [PDF]

, 2012
Understanding the spatial scale of gene flow can yield valuable insight into the ecology of an organism and guide conservation strategies. Fine-scale genetic structure is uncommon in migratory passerines because of their high vagility and presumed high ...

Green‐brown polymorphism in alpine grasshoppers affects body temperature

Ecology and Evolution, 2020
Ectothermic animals depend on external heat sources for pursuing their daily activities. However, reaching sufficiently high temperature can be limiting at high altitudes, where nights are cold and seasons short.

Effects of Roads and Traffic on Wildlife Populations and Landscape Function Road Ecology is Moving toward Larger Scales [PDF]

, 2011
Road ecology has developed into a significant branch of ecology with steady growth in the number of refereed journal articles, books, conferences, symposia, and “best practice” guidelines being produced each year. The main objective of this special issue
