Electroejaculate traits and circulating follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone concentrations were analyzed in adult leopard cats (Felis bengalensis), a rare felid species indigenous to east Asia. The ability of leopard cat sperm to bind and penetrate zona-free hamster ova and zona-intact domestic cat oocytes in vitro was examined as a means of testing sp...

The leopard (Panthera pardus) is a major predator of mammals within the rainforest ecosystem of West Africa. Most of the available information on leopard hunting behaviour comes from studies conducted in open savannah habitats, while little is known about forest leopards. Our radio-tracking data and scat analysis show that forest leopards differ in various ways from the savannah populations. Fo...

Motivation: The notion of texture is difficult to capture formally. Textures are usually the output of some random physical process wherein local structure is repeated seemingly at random and there is a lack of global structure. So, while the fur of a leopard is considered to be a texture, the entire leopard is not. This distinction is unavoidably arbitrary. We present an approach to texture re...

Many genes of large double-stranded DNA viruses have a cellular origin, suggesting that host-to-virus horizontal transfer (HT) of DNA is recurrent. Yet, the frequency of these transfers has never been assessed in viral populations. Here we used ultra-deep DNA sequencing of 21 baculovirus populations extracted from two moth species to show that a large diversity of moth DNA sequences (n = 86) ca...

Results After 80% ammonium sulphate precipitation, most of the proteins were recovered in 80% precitable fraction, 58.4% in moth and 71.2% in rice weevil. However, the recovery in supernatant was low 6.1% in rice weevil and 14.4 in moth extract. In ELISA inhibition of both the insect WBEs, most of the allergenic activity was recovered in 80% ammonium sulphate precipitate fraction (80% ppt). No ...

Gypsy moth defoliation of oak trees has been shown to lead to increased tannin levels, which, in turn, lead to reduced gypsy moth growth and fecundity. In laboratory experiments, increased tannin levels can interfere with the transmission of a virus that is consumed by larvae on oak foliage, and high mortality rates of larvae in the field are sometimes associated with low levels of defoliation....

at Day 7. Previously 1 frog with a renal tumor had been studied 7 days post hibernât ion; thus a total of 8 animals were examined. Light microscopio examination of the tumors showed that the amount of cellular debris increased within the lumina of the tumor tubules during this period. Electron microscopic observa tions showed that the lumina were filled with cellular debris as well as incomple...
