A Phenology Model for Asian Gypsy Moth Egg Hatch.

Phenology models are useful tools in pest management interventions, biosecurity operations targeting alien invaders, and answering questions regarding the potential for range expansion/shift. The Gypsy Moth Life Stage model (GLS) has been used to predict the invasive range of the North American gypsy moth (Lymantria dispar dispar Linnaeus [Lepidoptera: Erebidae]) in North America and New Zealand. It has been used to examine the role of supra-optimal temperatures in range expansion/stasis/retraction.

Age-Dependent Developmental Response to Temperature: An Examination of the Rarely Tested Phenomenon in Two Species (Gypsy Moth (Lymantria dispar) and Winter Moth (Operophtera brumata)).

The pervading paradigm in insect phenology models is that the response to a given temperature does not vary within a life stage. The developmental rate functions that have been developed for general use, or for specific insects, have for the most part been temperature-dependent but not age-dependent, except where age is an ordinal variable designating the larval instar. Age dependence, where age is a continuous variable, is not often reported (or investigated), and is rarely included in phenology models.

Model-specification uncertainty in future forest pest outbreak.

Climate change will modify forest pest outbreak characteristics, although there are disagreements regarding the specifics of these changes. A large part of this variability may be attributed to model specifications. As a case study, we developed a consensus model predicting spruce budworm (SBW, Choristoneura fumiferana [Clem.

Risk Reduction of an Invasive Insect by Targeting Surveillance Efforts with the Assistance of a Phenology Model and International Maritime Shipping Routes and Schedules.

Reducing the risk of introduction to North America of the invasive Asian gypsy moth (Lymantria dispar asiatica Vnukovskij and L. d. japonica [Motschulsky]) on international maritime vessels involves two tactics: (1) vessels that wish to arrive in Canada or the United States and have visited any Asian port that is subject to regulation during designated times must obtain a predeparture inspection certificate from an approved entity; and (2) vessels with a certificate may be subjected to an additional inspection upon arrival.

Fire regime zonation under current and future climate over eastern Canada.

Fire is a major disturbance in Canadian forests. Along with fuel and ignition characteristics, climatic conditions are seen as one of the main drivers of fire regimes. Projected changes in climate are expected to significantly influence fire regimes in Canada.

Unwanted spatial bias in predicting establishment of an invasive insect based on simulated demographics.

A strategy to estimate the probability of successful establishment of the invasive gypsy moth (given an introduction) is growing in popularity. The strategy calls for an examination of the demographic output of a phenology model of the complete life-cycle to estimate the generational success under the climate of the location under consideration. The probability is maximal where the climate satisfies the life-cycle requirements of all life-stages of 100% of the population every year.

Prepupal diapause and instar IV developmental rates of the spruce beetle, Dendroctonus rufipennis (Coleoptera: Curculionidae, Scolytinae).

The spruce beetle, Dendroctonus rufipennis (Kirby), is an important mortality agent of native spruces throughout North America. The life-cycle duration of this species varies from 1 to 3 years depending temperature. The univoltine cycle (one generation per year) is thought to maximize outbreak risk and accelerate host mortality in established outbreaks.

Hitchhikers on trade routes: A phenology model estimates the probabilities of gypsy moth introduction and establishment.

As global trade increases so too does the probability of introduction of alien species to new locations. Estimating the probability of an alien species introduction and establishment following introduction is a necessary step in risk estimation (probability of an event times the consequences, in the currency of choice, of the event should it occur); risk estimation is a valuable tool for reducing the risk of biological invasion with limited resources. The Asian gypsy moth, Lymantria dispar (L.

Role for PROMs data to support quality improvement across the healthcare system: an informed exchange with senior health system leaders.

The Institute for Healthcare Improvement's Triple Aim (initiated in 2007) and several high-level Canadian studies have made general calls to improve health system performance. Managers and administrators have been urged to tackle the challenges of quality improvement and cost control. In the lead essay, McGrail et al.

Age-dependent postdiapause development in the gypsy moth (Lepidoptera: Lymantriidae) life stage model.

For the last approximately 10 yr, the Gypsy Moth Life Stage (GLS) model has been used by pest managers to predict when important events in the gypsy moth, Lymantria dispar L., life cycle will occur (e.g.

Cost-justification of a clinical pharmacist-managed anticoagulation clinic.

A cost-benefit evaluation of a clinical pharmacist-managed anticoagulation clinic (AC) was performed. Outpatient and hospital records were examined for 26 patients in the treatment group with an AC clinic and 26 patients in the control group. Therapeutic prothrombin times were maintained within the treatment group to a significantly greater extent than within the control group (p<0.

New perspectives on the pharmacotherapy of ischemic stroke.

Objective: To provide an overview of the impact of ischemic stroke and the steps that can be taken to reduce its burden through greater awareness of the disease, improved diagnosis and better treatment, with emphasis on the use of antiplatelet agents.

Data Sources: Recent (1995-2003) published scientific literature, as identified by the authors through Medline searches, using the terms stroke, transient ischemic attack, cerebrovascular disease, atherothrombosis, risk factors, pharmacotherapy, prevention, and reviews on treatment.

Study Selection: Recent systematic English-language review articles and reports of controlled randomized clinical trials were screened for inclusion.
