The sandflies were collected from Beni-Suef district over one year, and identified as P. papatasii, P. sergenti and Sergentomia m. minuta. The first species was predominant and increased during hot months.

Cuticular hydrocarbons (CHCs) constitute an important class of chemical compounds present in the cuticular layer of insects, where their main functions are to prevent desiccation of the cuticle and as signals for intraspecific recognition. Studies concerning CHCs have shown a phenotypic flexibility of their composition, depending on environmental factors. However, the way that each of these factors influences this variation remains little explored.

People spend about 90% of their day indoors and are at increased risk of exposure to metal elements (MEs), water-soluble ions (WSIs) and polycyclic aromatic hydrocarbons (PAHs) contained in indoor PM. Therefore, firstly this study investigated indoor PM pollution to explore the distribution characteristics of MEs, WSIs and PAHs. Secondly, the carcinogenic risk of MEs and PAH to the population was analyzed using health risk assessment models.

Grass-dominated ecosystems cover wide areas of the land surface yet have received far less attention from the Earth System Model (ESM) community. This limits model projections of ecosystem dynamics in response to global change and coupled vegetation-climate dynamics. We used the Functionally Assembled Terrestrial Ecosystem Simulator (FATES), a dynamic vegetation demography model, to determine ecosystem sensitivity to alternate, observed grass allometries and biophysical traits, and evaluated model performance in capturing California C annual grasslands structure and fire regimes.

Ecosystem engineering is a facilitative interaction that generates bottom-up extrinsic variability that may increase species coexistence, particularly along a stress/disturbance gradient. American alligators (Alligator mississippiensis) create and maintain 'alligator ponds' that serve as dry-season refuges for other animals. During seasonal water recession, these ponds present an opportunity to examine predictions of the stress-gradient (SGH) and intermediate disturbance hypotheses (IDH).
