Every behaviourally responsive animal (including us) make decisions. These can be simple behavioural decisions such as where to feed, what to feed, how long to feed, decisions related to finding, choosing and competing for mates, or simply maintaining ones territory. All these are conflict situations between competing individuals, hence can be best understood using a game theory approach. Using some examples of classical games, we show how evolutionary game theory can help understand behavioural decisions of animals. Game theory (along with its cousin, optimality theory) continues to provide a strong conceptual and theoretical framework to ecologists for understanding the mechanisms by which species coexist. 相似文献

Lactoferrin, an iron-binding protein, has been proposed to act as an anti-infective agent and has been used as a diagnostic
marker in several inflammatory disorders. A sensitive enzyme-linked immunosorbent assay developed earlier was used for lactoferrin
estimation in cervical mucus. A brief study was undertaken to observe if lactoferrin is detectable in cervical mucus and to
correlate its level with reproductive tract infection, if present. One hundred and twelve cervical mucus samples were collected
from healthy as well as infected females. Some of these females were using CuT-200 intrauterine copper devices for contraception.
Women were at different phases of their menstrual cycle. The presence of detectable amount of lactoferrin in cervical mucus
was confirmed. The average level of lactoferrin in cases either with clinical symptoms of cervicitis or with proven infection
by PAP smear was significantly (t=7.6, P<0.01) higher than the normal controls. CuT users have higher (P<0.01) mean level
of lactoferrin than corresponding non-users. 相似文献
