Familiarity with a female does not affect a male's courtship intensity in garter snakes Thamnophis sirtalis parietalis

Creator:: Shine, Richard, Webb, Jonathan K., Lane, Amanda, and Mason, Robert T.
Abstract:: In many animal species, males direct more intense courtship towards females they have not previously encountered, than towards females with which they have previously mated. To test the factors responsible for this "Coolidge Effect", we need studies on a wide range of taxa – including those with mating systems in...

Can Investments in Social Capital Improve Well-Being in Fishing Communities? A Theoretical Perspective for Assessing the Policy Options

Creator:: Isham, Jonathan
Abstract:: Over the last decade, advocates of the interdisciplinary concept of social capital have celebrated the fact that elements of local social structures--embodied in social norms, networks and organizations--can significantly affect well-being in fishing communities. But does this concept bring anything to the study and practice of fisheries management that is...

Reproductive phase locking of mosquito populations in response to rainfall frequency

Creator:: Shaman, Jeffrey and Day, Jonathan F.
Abstract:: The frequency of moderate to heavy rainfall events is projected to change in response to global warming. Here we show that these hydrologic changes may have a profound effect on mosquito population dynamics and rates of mosquito-borne disease transmission. We develop a simple model, which treats the mosquito reproductive cycle...

Estimating Salinity Variance Dissipation Rate from Conductivity Microstructure Measurements

Creator:: Nash, Jonathan D. and Moum, James N.
Abstract:: At the smallest length scales, conductivity measurements include a contribution from salinity fluctuations in the inertial–convective and viscous–diffusive ranges of the turbulent scalar variance spectrum. Interpreting these measurements is complicated because conductivity is a compound quantity of both temperature and salinity. Accurate estimates of the dissipation rate of salinity variance...
