New MacrochelePratums species (Acari, Mesostigmata, Macrochelidae) associated with burying beetles (Silphidae, Nicrophorus) in North America
Burying beetles (Silphidae, Nicrophorus) are hosts to a broad diversity of mites (Acari), including several species of Macrocheles Latreille, 1829 (Mesostigmata, Macrochelidae). The macrochelid fauna associated with silphids primarily in North America was surveyed; in total, 1659 macrochelids representing seven species were collected from 112 Nicrophorus beetles representing nine host species. ...
متن کاملStarving the competition: a proximate cause of reproductive skew in burying beetles (Nicrophorus vespilloides).
Proximate mechanisms underlying reproductive skew are obscure in many animals that breed communally. Here, we address causes of reproductive skew in brood-parasitic associations of burying beetles (Nicrophorus vespilloides). Male and female burying beetles feed and defend their larvae on buried carcasses. When several females locate the same small carcass, they engage in violent physical alterc...
متن کاملBehavioral plasticity and G × E of reproductive tactics in Nicrophorus vespilloides burying beetles
Phenotypic plasticity is important in the evolution of traits and facilitates adaptation to rapid environmental changes. However, variation in plasticity at the individual level, and the heritable basis underlying this plasticity is rarely quantified for behavioral traits. Alternative behavioral reproductive tactics are key components of mating systems but are not often considered within a phen...

extraordinary financial pressures that the NIH currently experience threatens the US science enterprise. This not only puts extreme pressure on established scientists but makes it very difficult for young people to develop their research programs. The NIH have put in place mechanisms to make it easier for young people to obtain their first grant, but all this does is get new researchers through...
متن کاملSocial stimuli affect juvenile hormone during breeding in biparental burying beetles (Silphidae: Nicrophorus).
Extended biparental care is rare in insects but provides an excellent opportunity to investigate the interaction between the endocrine system and the physical and social environment in the regulation of this behavior. Burying beetles (Nicrophorus spp.) have facultative biparental care and depend on locating a small vertebrate carcass that they bury and prepare as food for their young. Commonly,...
