The role of backcountry huts as focal points for weed establishment and spread into New Zealand’s national parks has received little attention. In this study we describe the pattern of weed spread around Takahe Valley Hut, Murchison Mountains, Fiordland National Park. Established in 1948, the hut is located at 900 m a.s.l. at the ecotone between Nothofagus forest and valley floor shrubland/gras...

The importance of understanding the role of atmospheric conditions in pollen dispersal has grown in recent years with increased field-testing of genetically modified (GM) crop plants. An atmospheric model was used to characterize wind trajectories at 10 m and 100 m above GM pollen source fields located within a 4452-ha "control" area north of Madras, Oregon, USA, designated by the Oregon Depart...

Dead spot is a relatively new disease of creeping bentgrass (Agrostis stolonifera L.) incited by Ophiosphaerella agrostis Dernoeden, M.P.S. Câmara N.R. O’Neill van Berkum et M.E. Palm. Limited information is available with regards to chemical and cultural management strategies for dead spot. Two field studies were designed to evaluate the influence of various fertilizers and iprodione on the re...

We used long-term data on movements, survival, and reproduction of female red deer (Cervus elaphus Linnaeus) of the Isle of Rum, Scotland (1970-2001), to explain variation in life history (age at maturity) from a hind's access to habitat resources and exposure to local density, and cross-generational (maternal) effects on observed relationships. We described each hind's use of resources relativ...
