Pogonomyrmex magnacanthus Cole was described as a distinct species; unusually large eyes and a high ocular index (maximum eye diameter/head width) were listed as diagnostic characters. However, examination of numerous series of P. magnacanthus revealed that both characters were highly variable, and that these series consisted of P. magnacanthus plus an undescribed species, Pogonomyrmex hoelldob...

Conus californicus belongs to a genus of marine gastropods with more than 700 extant species. C. californicus has been shown to be distantly related to all Conus species, but showing unusual biological features. We report a novel peptide isolated from C. californicus with a significant inhibitory action over neuronal voltage-gated calcium channels. The new toxin is formed by 13-amino acid resid...

• Addition of two foods was better than one for Neoseiulus cucumeris establishment. plus artificial domatia promoted N. population growth. These supplementations enhanced the biological control efficiency .

Microbial growth in moisture-damaged buildings is associated with respiratory and other symptoms in the occupants. Streptomyces spp. are frequently isolated from such buildings. In the present study, we evaluated the responses of mice after repeated exposure to spores of Streptomyces californicus. Mice were exposed via intratracheal instillation to six doses (at 7-day intervals) of the spores o...

in the present study, for the first time, we document discovery of the predatory mite n. californicus in some rose greenhouses in yasouj, iran. furthermore, variation in spermathecal calyx shape is also discussed.

The accumulation of genetic incompatibilities between isolated populations is thought to lead to the evolution of intrinsic postzygotic isolation. The molecular basis for these mechanisms, however, remains poorly understood. The intertidal copepod Tigriopus californicus provides unique opportunities for addressing mechanistic questions regarding the early stages of speciation; hybrids between h...

Scent marking can provide behavioral and physiological information including territory ownership and mate advertisement. It is unknown how mating status and pair cohabitation influence marking by males from different social systems. We compared the highly territorial and monogamous California mouse (Peromyscus californicus) to the less territorial and promiscuous white-footed mouse (P. leucopus...

Aceria guerreronis Keifer can cause severe damage to coconuts in several countries around the world. Rare studies have been conducted to determine the predatory mites associated with A. guerreronis in Brazil. The study evaluated the prevalence of A. guerreronis and associated predators on the bracts and on the surface of the fruits underneath the bracts, for 12 months, on coconut palms grown al...
