We present a Markov chain model of succession in a rocky subtidal community based on a long-term (1986-1994) study of subtidal invertebrates (14 species) at Ammen Rock Pinnacle in the Gulf of Maine. The model describes successional processes (disturbance, colonization, species persistence, and replacement), the equilibrium (stationary) community, and the rate of convergence. We described succes...
Systematic correspondences can be found between Cantonese and Mandarin tones. For example, most of the words pronounced with tone 2 in Cantonese are pronounced with tone 3 in Mandarin (e.g., 找 ‘find’). Therefore, Cantonese speakers may mistakenly think that words where the Mandarin tone pronunciation does not follow the dominant pronunciation relationship (e.g., 摸 ‘touch’, pronounced with Canto...
An analytical system based on rRNA-targeted reverse transcription-quantitative PCR (RT-qPCR) for enumeration of catalase-negative, Gram-positive cocci was established. Subgroup- or species-specific primer sets targeting 16S or 23S rRNA from Enterococcus, Streptococcus, and Lactococcus were newly developed. The RT-qPCR method using these primers together with the previously reported primer sets ...
The Hawaiian Islands represent the most isolated land mass in the world, with no native ant species. To study invasive biology within two ant communities on Oahu, Hawaii we conducted laboratory bioassays to assess agonistic interactions among five introduced ant species: Leptogenys falcigera (Roger,), Camponotus variegatus (F. Smith), Anoplolepis gracilipes (F. Smith), Ochetellus glaber (Mayr),...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
Discoconchoecia elegans (Sars, 1865) is one of the most frequently recorded species of halocyprid ostracods and specimens are collected in abundance from various latitudes throughout the world oceans. This species is often dominant or subdominant member of the mesopelagic assemblages. However, its body size varies substantially with latitude, posing the question as to whether D. elegans is eith...
BACKGROUND There are several reports demonstrating the role of CD8 T cells against Leishmania species. Therefore peptide vaccine might represent an effective approach to control the infection. We developed a rational polytope-DNA construct encoding immunogenic HLA-A2 restricted peptides and validated the processing and presentation of encoded epitopes in a preclinical mouse model humanized for ...
