Impact Of Weed Management Practices On Grapevine Growth, Yield Components, Plant And Arthropod Abundance, And Carabid Seed Predation In Paso Robles Vineyard, Paolo Sanguankeo

Master's Theses

In the Central Coast of California, USA, wine grape growers are making efforts to identify weed control practices that promote biodiversity in their vineyards while maintaining yields. A field study was conducted in Paso Robles, CA in 2006 and 2007 evaluating the effect on Zinfandel grape-vine growth and production, groundcover plant, and ground dwelling arthropod communities of five weed control practices: 1) flumioxazin, 2) simazine, 3) cultivation, 4) cover crop, and 5) untreated control.

The herbicide treatments had the lowest weed biomass followed by the cultivation, being approximately 10 and 2 times lower than the weed biomass of either the …

Zooplankton Composition And Abundance In Lake Eğrigöl, A High Mountain Lake (Gündoğmuş, Antalya), Cem Aygen, Di̇dem Özdemi̇r Mi̇s, M. Ruşen Ustaoğlu, Süleyman Balik

Turkish Journal of Zoology

Field studies were conducted in July and August 2000, and in June and September 2001 in order to determine the zooplankton composition and abundance of Lake Eğrigöl, a high mountain lake located 2060 m a.s.l. in the middle Taurus Mountain Range. In total, 41 species were found, including 30 Rotifera, 8 Cladocera, and 3 Copepoda. Based on the number of species and their abundance (individuals m^{-3}), rotifers were the dominant group (49.75%-90.92%), followed by Cladocera (6.54%-27.52%), and Copepoda (2.54%-22.72%). All taxa were first records for the lake.

Diversity Of Alticinae (Coleoptera, Chrysomelidae) In Kasnak Oak Forest Nature Reserve, Isparta, Turkey, Ebru Gül Aslan, Yusuf Ayvaz

Turkish Journal of Zoology

Different habitat types chosen from Kasnak Oak Forest Nature Reserve (Isparta, Turkey) and 3 plots with vegetation structure, were studied comparatively with Alticinae (Coleoptera, Chrysomelidae) species composition, its richness and abundance. The study was conducted between the months of April and October at 15-day intervals during 2005 and 2006. Sixty-six sets of data were obtained during the survey, including 22 samplings for each plot. A total of 2650 individuals belonging to 57 species were recorded from the chosen plots. Species richness estimators were used to measure the completeness of the inventories. Values predicted by different non-parametric estimators showed that further …
