background: the best-known dangerous spiders belong to the six genera. the genus loxosceles or violin spiders are well known for their ability to cause skin necrosis or loxoscelism. all loxosceles species have medical im­portance due to their necrotizing venom. the present article reports the occurrence of l. rufescens in charkhab cave, south of iran (larestan). methods: the specimens were coll...

Angelina rufescens is placed within the core clade of Rhytismatales (Leotiomycetes, Pezizomycotina, Ascomycota) based on analysis of LSU and mtSSU rDNA. The only species in the genus, it produces distinctive ascomata that reoccur annually on wood and on the remains of its own previous fructifications, forming dense conglomerations of interlocking longitudinally elongated apothecia with gray hym...

BACKGROUND The best-known dangerous spiders belong to the six genera. The genus Loxosceles or violin spiders are well known for their ability to cause skin necrosis or loxoscelism. All Loxosceles species have medical importance due to their necrotizing venom. The present article reports the occurrence of L. rufescens in Charkhab Cave, south of Iran (Larestan).

Army ant predation by chimpanzees has been studied as an intriguing example of tool use and a possible case of cultural variation. However, the importance of army ant prey in chimpanzee diet and feeding ecology is still only poorly understood.We studied the availability and consumption of army ants in a population of the chimpanzee subspecies Pan troglodytes vellerosus in Nigeria. Army ants wer...

At least five species of Tupinambis lizards (Sauna: Teiidae) occur in South America east of the Andes. In Argentina and Paraguay, two species of Tupinambis have been of commercially exploited for the leather trade since the 1970s. Current quotas total 1.35 million skins/yr. Despite tbjs large and sustained harvest, few studies have examined genetic or morphological variation in these lizards. W...

T-complex testis expressed protein 1 domain containing 4 (TCTEX1D4) contains the canonical phosphoprotein phosphatase 1 (PPP1) binding motif, composed by the amino acid sequence RVSF. We identified and validated the binding of TCTEX1D4 to PPP1 and demonstrated that indeed this protein is a novel PPP1 interacting protein. Analyses of twenty-one mammalian species available in public databases and...

The fauna of freshwater gastropods the Arabian Peninsula, a desert land, is neither rich nor extensively studied. Only five species family Lymnaeidae have been recorded from this subcontinent so far. In February 2023, few specimens Radix rufescens (J. E. Gray, 1822) collected stream at Wadi Tiwi, NE Oman. shell, female part reproductive organs, prostate, paraeputium and phalloteca are presented...
