Endemic species on islands are considered at risk of extinction for several reasons, including limited dispersal abilities, small population sizes, and low genetic diversity. We used mitochondrial DNA (D-Loop) and 17 microsatellite loci to explore the evolutionary relationship between an endemic anemonefish, Amphiprion mccullochi (restricted to isolated locations in subtropical eastern Australi...
Traditionally, biodiversity conservation gap analyses have been focused on governmental protected areas (PAs). However, an increasing number of social initiatives in conservation (SICs) are promoting a new perspective for analysis. SICs include all of the efforts that society implements to conserve biodiversity, such as land protection, from private reserves to community zoning plans some of wh...
The genus Chrysodracon has six endemic species in the Hawaii Islands. Chrysodracon hawaiiensis is endemic to Hawaii Island and was described as a distinct species in 1980. It was listed as an endangered species on the International Union for the Conservation of Nature and Natural Resources (IUCN) Red List in 1997. This woody plant species was, at one time, common in exposed dry forests, but it ...
both zoonotic and anthroponotic cutaneous leishmaniasis (cl) caused by l. major and l. tropica, respectively, are endemic in different parts of iran. this study was performed to investigate the new changes in epidemiological pattern of cl, and to identify the species of leishmania and the strains of l. major isolated from different endemic areas of iran. seventy-two isolates from 245 samples co...
Flower morphology of 10 Fritillaria species of subgenera Theresia and Fritillaria growing wild in Iran is studied using seventy morphological characters. Qualitative and quantitative datasets separated taxa into subgenera, sectional and groups. Three enigmatic species F. caucasica, F. zagrica (endemic to Zagros Mountains) and F. pinardii (recently reported from Zagros Mountains) appeared as clo...
Malaria is a serious health problem in the tropical countries. Pregnant women are more susceptible malaria than non-pregnant women, but however its prevalence of is very less in both endemic and non-endemic areas. Congenital malaria (CM) is defined as malaria acquired by the foetus or new born from the mother, either in utero or at parturition. CM in tropical areas, where it is endemic is an im...
Roads have an important role in plants dispersal on different scales. Various plant species settle on roadsides, but some of them can enter the natural environments and threaten their biodiversity. Worldwide knowledge of roadside flora is necessary for local and global management of natural areas. Accordingly, the roadside flora of Northern Khorasan rangelands was studied along the 600 km ...
Background and Aim: Visceral leishmaniasis (kala-azar), the most dangerous form of leishmaniasis, is endemic in some parts of Iran, e.g. Ardabil, Fars, East Azerbaijan, Bushehr and Qom provinces. In recent years, the incidence of VL has increased in the Nourabad-Mamassani district in Fars Province. This study was carried out to detect VL vectors and infection rates in this region over the 2003-...
The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...
At present, approximately 187 genera and over 1300 species of Microsporidia have been described, among which almost half infect aquatic species and approximately 50 genera potentially infect aquatic arthropods. Lake Baikal is the deepest and one of the oldest lakes in the world, and it has a rich endemic fauna with a predominance of arthropods. Among the arthropods living in this lake, amphipod...
