Two groups of seven cats estimated preoperatively as good mice-killers were subjected to the damage of either the lateral hypothalamus (LH) or the ventro-posterior hypothalamus (VPH). The LH damage produced global impairment of the predatory behavior, such as interest in, catching, killing, or consuming the mouse, whereas VPH damage left intact most components of the predatory act, except for m...

The removal, or absence, of predatory species could be a contributing proximate factor to the rise of primate cathemerality. But predators themselves can also be cathemeral, so cathemerality could well be an evolutionary stable strategy. From a comparative perspective, it appears that the effect of predatory species cannot provide a unitary explanation for cathemerality. Varying distributions a...

Multidrug-resistant (MDR) Gram-negative bacteria have emerged as a serious threat to human and animal health. Bdellovibrio spp. and Micavibrio spp. are Gram-negative bacteria that prey on other Gram-negative bacteria. In this study, the ability of Bdellovibrio bacteriovorus and Micavibrio aeruginosavorus to prey on MDR Gram-negative clinical strains was examined. Although the potential use of p...

A major reason for security professionals not seeming able to protect fully against the rapidly changing threat environment and sophisticated attacks is that they often don’t have available the necessary application security data for detecting and responding to such increasingly stealthy attacks. Furthermore, easily generated application security data are generally not reported timely or accura...

A Quick Guide on grasshopper mice which, contrary to the great majority of mouse species, are obligate carnivores.

Bacteria, which prey on other microorganisms, are commonly found in the environment. While some of these organisms act as solitary hunters, others band together in large consortia before they attack their prey. Anecdotal reports suggest that bacteria practicing such a wolfpack strategy utilize antibiotics as predatory weapons. Consistent with this hypothesis, genome sequencing revealed that the...

Over one-year period, 150 pasture soil samples and 138 sheep faecal samples, collected from different parts of Iran were screened for the presence of nematophagous fungi. The samples were cultured at 25ºC on chloramphenicol-2% water agar (CHF-WA) plates in the presence of Haemonchus contortus third stage larvae (L3) and checked over a two-month period for characteristic conidia, conidiophores a...

Objective(s): Bdellovibrio-and-like organisms (BALOs) are predatory prokaryotes that attack and kill other Gram-negative bacteria for growth and reproduction. This study describes the isolation, identification, biological properties, and bacteriolytic activity of the first Bdellovibrio bacteriovorus with a broad prey range from Iran.Materials and Meth...

The portable cases constructed by caddisfly larvae have been assumed to act as a mechanical defense against predatory attacks. However, previous studies have compared the survival of caddisflies with different cases, thereby precluding an analysis of the survival benefits of "weaker" case materials. The level of protection offered by caddisfly cases constructed with rock, stick, or leaf materia...

We define predatory lending as a welfare-reducing provision of credit. Using a textbook model, we show that lenders profit if they can tempt households into “debt traps,” that is, overborrowing and delinquency. We then test whether payday lending fits our definition of predatory. We find that in states with higher payday loan limits, less educated households and households with uncertain income...
