Nests of the harvester ant Pogonomyrmex barbatus typically contain higher concentrations of organic matter, nitrogen and phosphorus than surrounding soils. The difference between nest soils and surrounding soils is due, at least in part, to ant foraging behavior. Ants retrieve seeds from the environment and concentrate seed nutrients in the vicinity of the nest. But elevated nutrient concentrat...

Plants used in traditional medicine in Bukoba Rural district in Tanzania were evaluated for their in vitro antimicrobial activities. Plant materials from eight plant species (Harungana madagascariensis (Lam) Poir., Jatropha curcas L., Lantana trifolia L., Plectranthus barbatus Andr., Pseudospondias microcarpa Engl., Psorospermum febrifugum Spach, Teclea nobilis Del. and Vernonia adoensis [Warp....

Aqueous leaf extract of Plectranthus barbatus was used, for the first time, preparation (2, 6 mol%) silver (Ag)-doped zinc sulfide nanoparticles (ZnS NPs), acting as a stabilizing and capping agent NPs’ production. The obtained metal oxides were characterized by FTIR, UV-visible, XRD, SEM methods. results revealed that 0.02 0.06% Ag-doped ZnS had optical bandgaps 3.20 3.03 eV. XRD evinced cryst...

We investigated the extent to which workers reproduce in a dependent-lineage population of the monogynous harvester ant Pogonomyrmex barbatus. Dependent-lineage populations contain two interbreeding, yet genetically distinct mitochondrial lineages, each associated with specific alleles at nuclear loci. Workers develop from matings between lineages, and queens develop from matings within lineage...

A preliminary study of boreal owl, Aegolius funereus richardsoni (Bonaparte), and northern sawwhet owl, Aegolius acadicus acadicus (Gmelin), nests from Nova Scotia, Canada revealed the presence of 14 species of Coleoptera, several of which represent significant extensions of their known ranges. Atheta (Datomicra) celata (Erichson) is newly recorded for North America; Atheta irrita Casey is newl...

Bu makale Faruk Duman’ın “Ve Bir Pars Hüzünle Kaybolur” (2014) ve “Sus Barbatus” (2018) romanlarında karakterlerin doğa ile kurdukları bağı karakterler insan dışı dünya arasındaki maddesel metafiziksel geçişkenlikleri Posthümanizm kuramı altında kendine yer bulan ekofeminist Stacy Alaimo tarafından ortaya konan Bedenler arası geçişkenlik teorisi üzerinden değerlendirip ekoeleştirel açıdan bu ge...

Speciation of two social parasites from their respective hosts is tested using a molecular phylogeny. Alignment of 711 DNA base pairs of mitochondrial cytochrome b gene was used to assess phylogenetic relationships of inquiline species to their hosts and to other members of the genus. We show that the inquiline social parasites of the North American seed harvester ants are monophyletic, descend...
