Latin America has experienced a vigorous growth in scientific production since the 1990s, rising from 1.7% of the world's share of science publications in 1990 to 3.2% in 2000. This appears to be a consequence of increasing investment in tertiary education, especially at the doctoral level. However, such growth is not homogeneous among the nations of Latin America, being affected by many issues, such as economical power and expenses in science and technology. Biology--including comparative biochemistry and physiology (CBP)--is one of the scientific areas of tremendous growth in the continent. Thus, in order to celebrate the increasing participation of Latin America in the field of CBP, the editorial board of Comp. Biochem. Physiol. decided to organize a special volume dedicated to Latin American authors (CBP-Latin America). From May to November 2005, 52 manuscripts were submitted to CBP-Latin America from Argentina, Brazil, Chile, Cuba, Mexico, Uruguay and Venezuela. This opening issue contains the first two dozen manuscripts, highlighting the diversity of experimental approaches and the breadth and uniqueness of the biological systems available to researchers in Latin America. We hope that the CBP-Latin America project becomes a significant editorial initiative, one that will meet the goals of highlighting, integrating, and mapping CBP research in Latin America.
Most of the global human population lives in urban areas where biogeochemical cycles are controlled by complex interactions between society and the environment. Urban ecology is an emerging discipline that seeks to understand these interactions, and one of the grand challenges for urban ecologists is to develop models that encompass the myriad influences of people on biogeochemistry. We suggest here that existing models, developed primarily in unmanaged and agricultural ecosystems, work poorly in urban ecosystems because they do not include human biogeochemical controls such as impervious surface proliferation, engineered aqueous flow paths, landscaping choices, and human demographic trends. Incorporating these human controls into biogeochemical models will advance urban ecology and will require enhanced collaborations with engineers and social scientists.
BioModels Database (http://www.ebi.ac.uk/biomodels/), part of the international initiative BioModels.net, provides access to published, peer-reviewed, quantitative models of biochemical and cellular systems. Each model is carefully curated to verify that it corresponds to the reference publication and gives the proper numerical results. Curators also annotate the components of the models with terms from controlled vocabularies and links to other relevant data resources. This allows the users to search accurately for the models they need. The models can currently be retrieved in the SBML format, and import/export facilities are being developed to extend the spectrum of formats supported by the resource.
