Two major genotypic assemblages of Giardia intestinalis infect humans; the nested real-time polymerase chain reaction (PCR) was used for targeting the triose phosphate isomerase (tpi) gene to detect and genotype G. intestinalis in human feces in Egypt. Among 97 fecal samples, 30 (31%) were diagnosed as giardiasis by saline wet mount microscopy after staining with Lugol's iodine. The tpi gene wa...

We present the results of a detailed taphonomic and zooarchaeological study of the faunal remains from the late Middle Palaeolithic (LMP) and early Upper Palaeolithic (EUP) bone assemblage of Ortvale Klde, Georgian Republic. A series of taphonomic tests and analyses are employed to reconstruct the depositional history of the bone assemblage and investigate LMP (Neanderthal) and EUP (Modern huma...

This study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the Coniacian–Santonian sediments of Tange-Bulfaris section. Five assemblage zones have been recognized by distribution of the foraminifera in the study area. Assemblage zone 1(Chara Ostracods zone) is Coniacian in age and occurs in the lower part of the succession. Assembl...

The plant family Orobanchaceae includes many parasitic weeds that are also impressive invaders and aggressive crop pests with several specialized features (e.g. microscopic seeds, parasitic habits). Although they have provoked several large-scale eradication and control efforts, no global evaluation of their invasive potential is as yet available. We use tools from ecological niche modeling in ...

Reservoirs are relatively new ecosystems with fish assemblages that include both native and introduced species. Spatial and temporal variability in such fish assemblages is difficult to predict from ecological theory. We characterized the dynamics of an offshore fish assemblage of Lake Texoma by sampling multiple fixed sites fortnightly with gill nets from 1981 to 1984 (402 net-nights). Univari...

Carnivoran-dominated fossil sites provide precious insights into the diversity and ecology of species rarely recovered in the fossil record. The lower level assemblage of Batallones-1 fossil site (Late Miocene; Madrid Basin, Spain) has yielded one of the most abundant and diversified carnivoran assemblage ever known from the Cenozoic record of mammals. A comprehensive taphonomic study is carrie...
