Brain Tuberculoma in a Non-endemic Area [PDF]
Infectious 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]
Systematic 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.

Endemism in historical biogeography and conservation biology: concepts and implications
Biogeographia, 2017 Endemism is often misinterpreted as referring to narrow distributions (range restriction). In fact, a taxon is said to be endemic to an area if it lives there and nowhere else.

PLoS ONE, 2021 Invertebrates in general have long been underrepresented in studies on biodiversity, biogeography and conservation. Boundaries of biodiversity hotspots are often delimited intuitively based on floristic endemism and have seldom been empirically tested ...

The genus Cliffortia (Rosaceae) in KwaZulu-Natal
Bothalia: African Biodiversity & Conservation, 2004 The only area of endemism for Cliffortia L. outside of the Cape Floristic Region (CFR) is centred in the northern KwaZulu- Natal Drakensberg. Eleven species of Cliffortia have been recorded from KwaZulu-Natal and distribution maps are provided for each ...

Childhood leprosy in an endemic area
Leprosy Review, 1999 A study was done on 794 new cases of leprosy among children (aged 0-14 years) detected and treated with MDT during 1990-1995 in Gudiyatham Taluk, South India. Incidence rates of leprosy and proportion of multibacillary cases increased with age, while bacillary + tuberculoid was most common.

Influence of current climate, historical climate stability and topography on species richness and endemism in Mesoamerican geophyte plants [PDF]
PeerJ, 2017 Background A number of biotic and abiotic factors have been proposed as drivers of geographic variation in species richness. As biotic elements, inter-specific interactions are the most widely recognized.
