EPIDEMIOLOGY OF MALARIA IN ENDEMIC AREAS [PDF]

open access: yesMediterranean Journal of Hematology and Infectious Diseases, 2012
Malaria infection is still to be considered a major public health problem in those 106 countries where the risk of contracting the infection with one or more of the Plasmodium species exists. According to estimates from the World Health Organization, over 200 million cases and about 655.000 deaths have occurred in 2010.

Biogeographic analysis of ferns and lycophytes in Oaxaca: A Mexican beta-diverse area

open access: yesBotan‪ical Sciences, 2021
Background: Spatial patterns related to richness and endemism of Mexican ferns and lycophytes are not well known, particularly in highly biodiverse areas; among these, Oaxaca is considered a highly biodiverse Mexican state.

The vascular plant species endemic or nearly endemic to Puebla, Mexico

open access: yesBotan‪ical Sciences, 2023
Background: Knowledge of endemism in a region (natural or political) is fundamental to determining natural biogeographic regions and establishing conservation priorities.

Brain Tuberculoma in a Non-endemic Area [PDF]

open access: yesInfectious Disease Reports, 2013
Brain tuberculoma has previously accounted for up to a third of new intracranial lesions in areas endemic with tuberculosis, but is unexpected in the United States and other Western countries with improved disease control. Here we show the importance of considering this diagnosis in at-risk patients, even with no definitive pulmonary involvement.

An Optimality Criterion to Determine Areas of Endemism [PDF]

open access: yesSystematic Biology, 2002
A formal method was developed to determine areas of endemism. The study region is divided into cells, and the number of species that can be considered as endemic is counted for a given set of cells (= area). Thus, the areas with the maximum number of species considered endemic are preferred.

Diversity centers as well as conservation priorities of the genus Onosma L. (Boraginaceae) in Iran

open access: yesTurczaninowia, 2022
Conservation of biological diversity is one of the most important issues in conservation biology, so a wide range of quantitative spatial methods have been used to determine the biodiversity hotspots and the conservation priority areas.

The living heart: Climate gradients predict desert mountain endemism

open access: yesEcology and Evolution, 2021
Mountain regions are centers of biodiversity endemism at a global scale but the role of arid‐zone mountain ranges in shaping biodiversity patterns is poorly understood.

On the identification of areas of endemism in the Neotropical montane cloud forests: A comparative review [PDF]

open access: yesFrontiers of Biogeography
Neotropical montane cloud forests are terrestrial ecosystems characterized by a consistent high humidity from clouds or mist. Geographically, these forests occur along the Andes, Mesoamerica, and the Caribbean mountain ranges.

Predictors of plant endemism in two west African forest hotspots

open access: yesFrontiers in Ecology and Evolution, 2022
Centres of endemism have been much studied by biogeographers, ecologists, and evolutionary theorists, and are considered conservation priorities. It is therefore important to understand the ecological traits of restricted range taxa, and the landscape ...
