Predicting County-Level Southern Pine Beetle Outbreaks From Neighborhood Patterns

ENVIRONMENTAL ENTOMOLOGY, 40(2), 273–280.

By: A. Duehl*, J. Bishir n & F. Hain n

author keywords: southern pine beetle; cellular automata; county pattern; forest damage
TL;DR: This study determined how accurately patterns of county-level infestations in preceding years could predict infestation in the current year and if there were emergent patterns that correlated strongly with beetle outbreaks. (via Semantic Scholar)

2008 journal article

BCWEEVIL: A simulation model of the joint population dynamics between spruce weevil and Sitka spruce, over the lifetime of a plantation

ECOLOGICAL COMPLEXITY, 5(3), 260–271.

By: J. Bishir n, A. Yanchuk*, J. Russell* & K. Polsson*

author keywords: simulation model; population dynamics; Sitka spruce; spruce and white pine weevil; Pissodes strobi
TL;DR: A computer simulation model of the joint population dynamics within this tree/pest system, over the lifetime of a plantation, is described, and is combined with the Province of British Columbia's Tree and Stand Simulator (TASS) to drive individual tree growth and stand establishment and development.

2006 journal article

Variation in volume production through clonal deployment: Results from a simulation model to minimize risk for both a currently known and unknown future pest

SILVAE GENETICA, 55(1), 25–37.

By: A. Yanchuk*, J. Bishir n, J. Russell* & K. Polsson*

author keywords: clonal forestry; genetic diversity; risk; merchantable volume loss; insect resistance
TL;DR: Reducing the effects of insect activity and attack on trees, by lowering the average annual temperature in the model, or turning off all insect ‘activity’, increased merchantable volume but did not change the optimum number of clones (~18) or deployment pattern (random mixture).

2004 journal article

On-bark behavior of Dendroctonus frontalis: a Markov chain analysis

JOURNAL OF INSECT BEHAVIOR, 17(3), 281–301.

By: J. Bishir n, J. Roberds* & B. Strom*

author keywords: Scolytidae; southern pine beetle; host selection; host recognition; transition probabilities; absorbing states
TL;DR: This work applied Markov chain analysis to on-bark behaviors of the southern pine beetle, Dendroctonus frontalis Zimmermann, and found that by developing chains for each sex, sexually dichotomous fighting behaviors were revealed. (via Semantic Scholar)

1997 journal article

Limit theorems and a general framework for risk analysis in clonal forestry

MATHEMATICAL BIOSCIENCES, 142(1), 1–11.

By: J. Bishir n & J. Roberds n

MeSH headings : Forestry / statistics & numerical data; Mathematics; Models, Biological; Risk; Trees / genetics; Trees / growth & development
TL;DR: It is shown that the proportion S converges in distribution and that, under general conditions, a moderate number of clones, usually no more than 20 to 40 and often fewer, provides equivalent or better protection against catastrophic loss than does a large number of clone.

Risk analyses in clonal forestry

Roberds, J. H., & Bishir, J. W. (1997, March). CANADIAN JOURNAL OF FOREST RESEARCH-REVUE CANADIENNE DE RECHERCHE FORESTIERE, Vol. 27, pp. 425–432.

By: J. Roberds* & J. Bishir*

TL;DR: Alternative models and methods that have been proposed to investigate the effect of number of clones on risk of plantation failure following an unforeseen catastrophic event indicate that use of 30 to 40 unrelated clones in plantations provides protection against catastrophic failure roughly equivalent to the use of large numbers of unrelated clones.
