  • And Engelmann Oak (Q. Engelmannii) at the Acorn and Seedling Stage1
    Insect-oak Interactions with Coast Live Oak (Quercus agrifolia) and Engelmann Oak (Q. engelmannii) at the Acorn and Seedling Stage1 Connell E. Dunning,2 Timothy D. Paine,3 and Richard A. Redak3 Abstract We determined the impact of insects on both acorns and seedlings of coast live oak (Quercus agrifolia Nee) and Engelmann oak (Quercus engelmannii E. Greene). Our goals were to (1) identify insects feeding on acorns and levels of insect damage, and (2) measure performance and preference of a generalist leaf-feeding insect herbivore, the migratory grasshopper (Melanoplus sanguinipes [Fabricus] Orthoptera: Acrididae), on both species of oak seedlings. Acorn collections and insect emergence traps under mature Q. agrifolia and Q. engelmannii revealed that 62 percent of all ground-collected acorns had some level of insect damage, with Q. engelmannii receiving significantly more damage. However, the amount of insect damage to individual acorns of both species was slight (<20 percent damage per acorn). Curculio occidentis (Casey) (Coleoptera: Curculionidae), Cydia latiferreana (Walsingham) (Lepidoptera: Tortricidae), and Valentinia glandulella Riley (Lepidoptera: Blastobasidae) were found feeding on both species of acorns. No-choice and choice seedling feeding trials were performed to determine grasshopper performance on the two species of oak seedlings. Quercus agrifolia seedlings and leaves received more damage than those of Q. engelmannii and provided a better diet, resulting in higher grasshopper biomass. Introduction The amount of oak habitat in many regions of North America is decreasing due to increased urban and agricultural development (Pavlik and others 1991). In addition, some oak species are exhibiting low natural regeneration. Although the status of Engelmann oak (Quercus engelmannii E.

  • Direct Effects of Carpophagous Insects on the Germination Ability and Early Abscission of Oak Acorns
    Acta Silv. Lign. Hung., Vol. 2 (2006) 57-68 Direct Effects of Carpophagous Insects on the Germination Ability and Early Abscission of Oak Acorns * György CSÓKA – Anikó HIRKA Department of Forest Protection, Forest Research Institute, Mátrafüred, Hungary Abstract – Carpophagous insects play an important role in decreasing the viability of acorns in both direct and indirect ways. Therefore they significantly influence the reproductive potential of oaks. As a direct effect, their feeding on the embryo and on the cotyledons may prevent the germination of the acorn and on the other hand, their damage causes premature acorn abscission. During 3 years, 60 acorn samples from five oak species (Turkey oak – Quercus cerris, pedunculate oak – Quercus robur, sessile oak – Quercus petraea, downy oak – Quercus pubescens, red oak – Quercus rubra) have been investigated. The average rate of damage varied a lot between years, but was always significant (2000: 36%, 2001: 61%, 2002: 51%). The insects’ influence causing premature acorn abscission was significant both for pedunculate and Turkey oaks. The premature acorn abscission was 34% of the total crop in 2000 for pedunculate oak (Curculio spp. 26%, Cydia spp. 2% and Andricus quercuscalicis 6%) and 39% in 2001 (Curculio spp. 14%, Cydia spp. 2%, Andricus quercuscalicis 13%, Callirhytis glandium 10%). In case of Turkey oak it was 29% in 2001 (C. glandium 16%, Neuroterus saliens 13%, and 12% in 2002 (C. glandium 10%, N. saliens 2%). oaks / Quercus, / acorn / carpophagous insects / germination ability/ early abscission Kivonat – A karpofág rovarok közvetlen hatása tölgymakkok csíraképességére és korai hullására.

  • On Garry Oak (Quercus Garryana) Acorn Germination on Vancouver Island
    The Effects of the Filbert Weevil (Curculio occidentis) and the Filbertworm (Cydia latiferreana) on Garry Oak (Quercus garryana) Acorn Germination on Vancouver Island. An undergraduate research project by Jennifer Waller Submitted in partial fulfillment of the requirements for the Bachelor of Science degree at Malaspina University-College, Nanaimo, British Columbia April, 2006 ABSTRACT Garry oak trees (Quercus garryana) and their associated ecosystems are among the most diverse and endangered landscapes in B.C. Garry oak acorns are susceptible to two insect species, the Filbert weevil (Curculio occidentis) and the Filbertworm (Cydia latiferreana). The objective of this study was to determine the effects of the Filbert weevil and the Filbertworm on Garry oak acorn germination on Vancouver Island. In the fall of 2005 a total of 1,985 Garry oak acorns were collected from 8 locations: three sites in Victoria, two sites in Nanaimo, two sites in the Comox Valley, and from Hornby Island. The acorns were observed for species-specific insect exit-hole damage, planted in potting soil, labeled as either insect-damaged or undamaged, then watered and observed for germination until December. The acorns were then removed from their containers, inspected, and insect damage was recorded. Five of the 8 sites indicated a trend that undamaged acorns were more likely to germinate than insect-damaged acorns. For example, the highest percent germination was 99% of undamaged acorns and 84% of insect-damaged acorns at one site in Courtenay. The highest total insect abundance based on insect exit holes, was 1.3 insects per acorn at the other Courtenay site.

Recruitment appears to be independent of species. Recruitment failure is generally due Most pericarps were easily separated from the inner seed coat, but this step proved to failure in Quercus communities could have a significant effect on forest to many factors which impact the many stages of the plants life. Most be difficult with variation between infested acorns and un-infested. Acorns without larva (“un-infested”) had harder pericarps which would fragment into large pieces trophic systems. Herbivory has been hypothesized to be a major limiting factors are assigned as pre-germination or post-germination, however, allowing for easy removal. The acorns that contained larva (“infested”), however, factor in the maturation of Quercus species. Specifically insect herbivores juveniles are very numerous compared to adults; so lack of recruitment tended to have flimsy shells that fragmented into small pieces and were very difficult such as Curculio occidentis (Filbert Weevil) could play a large role in the appears to not occur at pre-germination stage, but later after juveniles to remove. Average overall mass decreased by approximately 30% when the pericarp was removed. It should be noted however that in acorns with more than two weevils, recruitment failure, as they attack the oak at its most fragile state, the establish, or post-germination (Purohit, 2009).

Sousa, Co-Chair Professor Thomas J. Carlson, Co-Chair Professor Scott L. Stephens Frank K. Lake, Ph.D. Spring 2016 Abstract Prescribed fire and tanoak (Notholithocarpus densiflorus) associated cultural plant resources of the Karuk and Yurok Peoples of California by Arielle Anita Halpern Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Wayne P. Sousa and Professor Thomas J. Carlson, Co-Chairs The targeted application of prescribed fire has long been used by Native Californian peoples to manage plant resources of cultural value. Their ability to employ this management tool has been increasingly restricted by local, state and federal agencies in response to recent drought conditions and the highly flammable state of most western U.S. forests, where, for decades, fires of any magnitude have been suppressed as a matter of policy. This diminished access to cultural prescribed fire has impacted tribal access to many of the plant resources and cultural activities upon which Karuk and Yurok cultures are based.
