  Family PTEROMALIDAE
Graham (1969) runs this subfamily to 11 couplets of his 54 couplet key, so that between the Miscogasterinae (with 12 couplets) and Pteromalinae (with 11), nearly one-half the couplets are devoted to various morphological groupings of the 2 subfamilies.
BIOLOGY: The species are parasites of Scolytidae and Curculionidae on coniferous trees (Graham 1969), and we have seen specimens reared from twigs of the evergreen broadleaf California-Bay (Umbellularia californica).
BIOLOGY: Although biology is unknown for the subfamily, it has been collected on dead or felled trees, and the long ovipositor is typical of wasps that parasitize wood-boring larvae (LaSalle and Stage 1985).

 Stegocephalidae
Biology: The knowledge of the biology of the Stegocephalidae mainly concerned the fact that they are mostly true deep-sea species, and that, although they do have the globular body form of the pelagic hyperiids, most species appear to be hyperbenthic.
The genus Bathystegocephalus should, according to the cladogram, be considered as the type genus of a monotypic subfamily, and the sister taxon to the clade consisting of the three subfamilies Andaniexinae, Andaniopsinae and Stegocephalinae.
The present subfamily is the largest of the five stegocephalid subfamilies (cladogram), both in number of species and genera.

The subfamily Eriogonoideae is a diverse group of shrubs, herbaceous perennials, and annuals that is characterized by the absence of sheathing leaf stipules (ocrea), and the presence of a whorl of inflorescence bracts subtending each inflorescence node and a whorl of involucral bracts subtending each flower or cluster of flowers.
The majority of taxa in the subfamily are aligned with one of two large genera, Eriogonum (wild buckwheat, ~240 spp.) and Chorizanthe (spineflower, 40 N. American spp.).
The remaining 15 genera in the subfamily are small, largely monotypic taxa.

 Biology of the Manta Ray
NEW - "Biology of Sharks and Rays" on-line course
Since following a systematic scheme that retains Rhinoptera in its own subfamily, Rhinopterinae, and Shirai's Aetobatinae (which appeals to me as an interesting and provocative way to group Aetobatus, Aetomylaeus and Pteromylaeus) are in no way inconsistent with McEachran et al.
The proposed taxonomic schemes of these workers will no doubt spur much research and be highly influential in decades to come, but advances in cladistic methodology and the application of molecular genetics render it unlikely that either scheme will be the final word on batoid systematics.

Details of crocodilian biology as it pertains to their management and conservation can be found in Webb et al.
It is noteworthy that neither survey or monitoring need generate an absolute estimate of the number of crocodilians present, as long as a reliable index of the trend (increasing or decreasing) is obtained.
Biology: Exploitation of the crocodilian population was structured to focus harvest on those life stages where high mortality has the least affect on the population.

 ANT BIOLOGY   (Site not responding. Last check: 2007-11-07)
Worker ants are easily recognized by their combination of a constricted waste at the front of their abdomen combined with their lack of wings.
While we usually think of ants as having a sting, many common ants lack a sting; these are in subfamily Formicinae; if you pick up an ant in this subfamily and sniff it, you'll detect the sharp odor of formic acid, which is used as a defensive chemical by these ants.
The few vestiges of wasp-like behavior in the "primitive" Australian ants--Nothomyrmecia and the bulldog ants, Myrmecia--include the use of their sting when capturing insect prey, relying on vision to find and track prey, and moving on the ground with rapid, jerky movements, much like the movements of spider wasps.

 The catalytic mechanism of the ESA1 histone acetyltransferase involves a self-acetylated intermediate - Nature ...   (Site not responding. Last check: 2007-11-07)
Yeast ESA1 is a member of the MYST subfamily of histone acetyltransferases (HATs), which use acetyl-coenzyme A (CoA) to acetylate specific Lys residues within histones to regulate gene expression.
However, this mode of catalysis differs dramatically from the GCN5/PCAF subfamily, which mediate direct nucleophilic attack of the acetyl-CoA cofactor by the enzyme-deprotonated substrate lysine of the histone.
These results demonstrate that different HAT subfamilies can use distinct catalytic mechanisms, which have implications for their distinct biological roles and for the development of HAT-specific inhibitors.
