Bromus tectorum L. is an invasive winter annual grass naturalized across the United States. Numerous studies have investigated B. tectorum population structure and genetics in the context of B. tectorum as an ecological invader of natural areas and rangeland. Despite the wealth of information regarding B. tectorum, previous studies have not focused on, or made comparisons to, B. tectorum as it ...

Phylogenetic analyses, from polymerase chain reaction (PCR)-amplified 12S rRNA and 18S rRNA gene sequences from cochineal insects of the genus Dactylopius present in Mexico, showed that D. ceylonicus, D. confusus, and D. opuntiae are closely related. D. coccus constitutes a separate clade, and D. tomentosus is the most distantly related. Bacterial 16S rRNA sequences from all the Dactylopius sp...

Gili Meno is one of the leading small (gili) tourist islands in North Lombok Regency, West Nusa Tenggara Province. Massive tourism activities have an impact on marine biota, including crabs. This research to determine characteristics crab family Xanthidae intertidal zone Beach, The was conducted using exploratory method by measuring abiotic factors aquatic environment which habitat Based resear...

Exogenous nitrogen (N) inputs greatly change the emission and uptake of carbon dioxide (CO2) methane (CH4) from temperate grassland soils, thereby affecting (C) budget regional terrestrial ecosystems. Relevant research focused on natural grassland, but effects N fertilization C exchange fluxes different forage soils driving mechanisms were poorly understood. Here, a three-year addition experime...

Cells of the terrestrial plant species bromegrass (Bromus inermis L.) are not naturally adapted to withstand the hydrostatic pressures encountered in aquatic environments. However, after treatment with the natural plant growth hormone abscisic acid (75 micromolar), bromegrass cells survived a hydrostatic pressure of 101.3 megapascals, approximating the limits of ocean depth (10,860 m). The incr...
