Green turtle somatic growth dynamics in a spatially disjunct Great Barrier Reef metapopulation

Chaloupka, Milani; Limpus, Colin; Miller, Jeffrey - 2004

The growth dynamics of green sea turtles resident in four separate foraging grounds of the southern Great Barrier Reef genetic stock were assessed using a nonparametric regression modeling approach. Juveniles recruit to these grounds at the same size, but grow at foraging-ground-dependent rates...

STOCHASTIC TECHNOLOGY, RISK PREFERENCES AND ADOPTION OF SITE-SPECIFIC TECHNOLOGIES

Isik, Murat; Khanna, Madhu - 2002

This paper develops a model of farmer decision-making to examine the extent to which uncertainties about the performance of site-specific technologies (SSTs) and about the weather impact the value of these technologies. The model uses the jointly estimated risk and technology parameters to...

SPATIAL BREAK-EVEN VARIABILITY FOR CUSTOM HIRE VARIABLE RATE TECHNOLOGY ADOPTION

Mahajanashetti, S.B.; English, Burton C.; Roberts, Roland K. - Agricultural and Applied Economics Association - AAEA - 1999

A theoretical model identified ranges of spatial variability required within multiple-land-class fields for … economically viable variable rate technology (VRT) and the spatial variability required for maximum return to VRT. An example … illustrated that return to VRT and the viable range of spatial variability increased for higher corn and nitrogen prices. …
