Intertidal encapsulated embryos may be synchronously exposed to many environmental stressors, but interactions between some of these factors remain poorly understood. Here, the effects of solar radiation and desiccation on embryonic mortality and developmental rates were assessed using laboratory and field experiments. Egg masses of 3 intertidal gastropod species were exposed for 72 h to combinations of spectral (full spectrum, UV-blocked, dark) and daily emersion treatments (control, 15, 30, 60 min). Siphonaria denticulata and Bembicium nanum embryos were expected to be tolerant to emersion and UVR as they are routinely deposited on exposed rock platforms. In contrast, Dolabrifera brazieri embryos …

Watershed management has become a prominent approach to natural resource management (NRM) in Australia and elsewhere. In the Australian State ofNew South Wales (NSW), catchment management - the NSW watershed management initiative - has been in place both in coastal and non-coastal areas for nearly two decades. In coastal areas, it is suggested that catchment management could play an important role in coastal and marine issues (NSW Coastcare et aI., 2004; Zann, 1996), as the Australia's coastal and marine environments have, in general, been affected by watershed-based activities (see e.g., Zann, 1996). Such a role would, however, require institutional changes, …
