Indirect predator effects on clutch size and the cost of Egg production

Abstract Predator-induced changes in physiology and behaviour may negatively affect a prey’s birth rate. Evidence of such indirect predator effects on prey demography remains scarce in birds and mammals despite invertebrate and aquatic studies that suggest ignoring such effects risks profoundly underestimating the total impact of predators. We report the first experimental demonstration of indirect

Ospika Cones Ecological Reserve #152 Maps

This reserve is only accessible by helicopter and one must have a permit to access it as it is such  a fragile ecosystem. Below is a satellite map view of both Sikanni Chief River (ER #42) and Ospika Cones Ecological reserves (ER # 152) in relation to Redfern -Kelly Provincial park. Both maps are adapted

Effectiveness of a five-minute Demolition Interval to Mitigate Blasting Noise Impacts in Military Training Area WQ on Sea Lions in the Race Rocks Ecological Reserve, B.C.

Executive Summary: Noise from explosions at the Bentinck Island Demolition Range at Canadian Forces Ammunition Depot (CFAD) Rocky Point has the potential to disturb pinnipeds (seals and sea lions) hauled out in the Race Rocks Ecological Reserve (RRER). Such disturbance is prohibited by the Marine Mammal Regulations (MMRs) under the Fisheries Act and may be

Set-back Distances to protect nesting and roosting seabirds off Vancouver Island from boat disturbance

Trudy Chatwin’s Master’s theses from Royal Roads University. ABSTRACT: In order to set guidelines that promote responsible wildlife viewing, I quantified the effects of boat-based disturbance to seabirds off Vancouver Island. Field trials recorded the approach distance at which roosting and nesting birds responded to either a motor boat or a kayak. Probability of agitation
