CBGP : Centre de Biologie et de Gestion des Populations. Home. With this final issue of the Newsletter on Ticks and Tick-borne Diseases of Livestock in the Tropics, the ICTTD project comes to an end.


The sustained support from the European Commission through ICTTD 1, 2 and 3 has made it possible to create a global consortium on ticks and tick-borne diseases. ThisNewsletter, which was first published in 1996, has played an important role in this development by bringing together the latest information on published research and served as a source of information for members of the network. Many, many thanks to the editor-inchief, Gerrit Uilenberg, and his team of co-editors for creating 42 wonderful Newsletter issues over the past 14 years! NSF-EID Lyme disease gradient project. NSF Emerging Infectious Disease Award EF-0914476 Lyme disease (LD) is the most common vector-borne disease of humans in the U.S., with most cases acquired from the bite of nymphal blacklegged ticks (= ‘deer ticks’).

These ticks are found throughout the eastern U.S. (see map), yet 93% of LD cases occur in ten Northeast, Mid-Atlantic and Upper Midwest states. Various explanations have been proposed for the puzzling absence of LD in some areas where blacklegged ticks occur, but no agreement has been reached – contributing to uncertainty and confusion among citizens and healthcare providers faced with expanding tick populations in many parts of the U.S.

More about this map. Tree of Life Web Project. The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world.

Tree of Life Web Project

On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.

Construction of recombinant DNA, in which a foreign DNA fragment is inserted into a plasmid vector.

Recombinant DNA

In this example, the gene indicated by the white color is inactivated upon insertion of the foreign DNA fragment. Recombinant DNA (rDNA) molecules are DNA molecules formed by laboratory methods of genetic recombination (such as molecular cloning) to bring together genetic material from multiple sources, creating sequences that would not otherwise be found in biological organisms.

Free conservation biology textbook: Conservation Biology for All

A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous text boxes describing additional relevant material or case studies are also included.
