Keeping the herds healthy and alert: Implications of predator control for infectious disease Keeping the herds healthy and alert: Implications of predator control for infectious disease
Predator control programmes are generally implemented in an attempt to increase prey population sizes. However, predator removal could prove harmful to prey populations that are regulated primarily by parasitic infections rather than by predation. We develop models for microparasitic and macroparasitic infection that specify the conditions where predator removal will (a) increase the...

Factors influencing the variation in capture rates of shrews in southern California, USA Factors influencing the variation in capture rates of shrews in southern California, USA
We examined the temporal variation in capture rates of shrewsNotiosorex crawfordi (Coues, 1877) and Sorex ornatus (Merriam, 1895) in 20 sites representing fragmented and continuous habitats in southern California, USA. InN. crawfordi, the temporal variation was significantly correlated with the mean capture rates. Of the 6 landscape variables analyzed (size of the landscape, size of the...

Sea otter population declines in the Aleutian Archipelago Sea otter population declines in the Aleutian Archipelago
Sea otter (Enhydra lutris) populations were exploited to near extinction and began to recover after the cessation of commercial hunting in 1911. Remnant colonies of sea otters in the Aleutian archipelago were among the first to recover; they continued to increase through the 1980s but declined abruptly during the 1990s. We conducted an aerial survey of the Aleutian archipelago in 2000...

Introduction to fire danger rating and remote sensing - Will remote sensing enhance wildland fire danger prediction? Introduction to fire danger rating and remote sensing - Will remote sensing enhance wildland fire danger prediction?
While ‘Fire Danger’ per se cannot be measured, the physical properties of the biotic and abiotic world that relate to fire occurrence and fire behavior can. Today, increasingly sophisticated Remote Sensing methods are being developed to more accurately detect fuel properties such as species composition (fuel types), vegetation structure or plant water content - to name a few. Based on

Effects of increased soil nitrogen on the dominance of alien annual plants in the Mojave Desert Effects of increased soil nitrogen on the dominance of alien annual plants in the Mojave Desert
1. Deserts are one of the least invaded ecosystems by plants, possibly due to naturally low levels of soil nitrogen. Increased levels of soil nitrogen caused by atmospheric nitrogen deposition may increase the dominance of invasive alien plants and decrease the diversity of plant communities in desert regions, as it has in other ecosystems. Deserts should be particularly susceptible to...
