Till now only two species of the genus Trichocera, T. annulata and T. hiemalis, were recorded from north Africa. Herewith, we document seven species from Morocco, which extend distribution of the genus and the family to most southern localities of the western Palearctics in Africa (mountain ranges: the Rif, Middle Atlas and Beni Snassen). The following species were found: one new species in the...

Bacteriophages were observed in forestomach contents from three species of Australian macropodoid marsupials possessing a foregut fermentative digestion: the eastern grey kangaroo (Macropus giganteus), the eastern wallaroo (Macropus robustus robustus), and the rufous bettong (Aepyprymnus rufescens). Forty-six morphologically distinct phage types, representing the families Myoviridae, Siphovirid...

In certain, infrequently occurring, favorable circumstances the ants P. rufescens can display patterns of behavior which seem to be disappearing as a result of their parasitic way of life: the ability to food themselves, independently though ineffectively, elements of the offspring-protection behavior, transporting of nestmates, escape reaction. Similar events reinforce the infrequently used, l...

We describe a new species of Bolitoglossa (Nanotriton) from the Sierra de Juárez and Sierra Mixe of Oaxaca, Mexico. Bolitoglossa chinantecasp. n. is distinguished from the three other species in the subgenus Nanotriton by its more robust body, by having substantial numbers of maxillary teeth and differences in relative head width, foot width, and limb length. The new species occurs in sympatry ...

The threatened Kirtland’s warbler Dendroica 25 pairs and at least nine nests fledged young. One male ringed as a fledgling returned to breed in two subsequent kirtlandii breeds in stands of young jack pine Pinus banksiana growing on well-drained soils in Michigan, years. After a 19-year period of population stability, the Kirtland’s warbler population increased four-fold during USA. We summariz...

All California abalone species have been shown to be susceptible to infection with the bacterial agent of abalone withering syndrome (WS), although expression of signs of the disease may vary between species and with environmental conditions. We examined thermal modulation of WS expression in green abalone Haliotis fulgens at temperatures mimicking El Niño (18.0°C) and La Niña (14.2°C) events i...
