Check out my new website….
This will be my main hub of updates and ideas
So my big news is that I am now officially a part of Dr. Sabrina Russo’s lab at the University of Nebraska-Lincoln. This will be my academic abode for the next few years. Tantalizing opportunities on the horizon include research on tropical islands with unusually high levels of biodiversity and working with plants that have specialized adaptations to specific soil types. Stay posted for interesting news from the prairie-jungle…
Sampling forest canopy arthropod biodiversity with three novel minimal-cost trap designs
Bar-Ness, Y. D., McQuillan, P. B., Whitman, M., Junker, R. R., Cracknell, M. and Barrows, A. (2011), Sampling forest canopy arthropod biodiversity with three novel minimal-cost trap designs. Australian Journal of Entomology. doi: 10.1111/j.1440-6055.2011.00836.x
Sampling arthropods in the upper canopy of tall trees presents a range of challenges associated with portability, cost, placement, replication and collection. Detailed schematics and instructions are presented here for three trap designs: sticky CD cases, plastic bottle hanging flight-intercept traps and drink bottleneck funnel crawl traps. By using simple and salvageable materials such as plastic drink bottles and compact disc cases, the financial cost of an arthropod sampling regime in the crowns of old-growth Tasmanian stringybark trees Eucalyptus obliqua (L’Herit) was kept to a minimum. The traps collected comparatively diverse communities: the sticky traps catching high levels of Diptera, Hymenoptera and Coleoptera; the funnel traps catching Diptera, Hemiptera and Coleoptera; and the hanging traps catching Diptera, Coleoptera and Lepidoptera. The sticky traps were ranked best, and the funnels worst, when integrating relative merits of cost, transport, durability, construction, placement, retrieval, sorting and arthropod condition.

Conservation of Madagascar’s granite outcrop orchids: the influence of fire and moisture.
Whitman, M., M. Medler, J.J. Randriamanindry, & E. Rabakonadrianina. 2011. Conservation of Madagascar’s granite outcrop orchids: the influence of fire and moisture. Lankesteriana International Journal on Orchidology 11(1): 55-67.
Is there a difference in response to disturbance, or resource limitation, by similar taxa based on micro-site habitat heterogeneity? For this study we examined how fire and moisture availability influences the distribution of terrestrial and lithophytic orchids specific to Madagascar’s granite outcrops (inselbergs). We compared orchid density in an area with a complex mosaic of burned and non-burned vegetation patches (three years after the event). Lithophytic species (subtribe Angraecinae) were sensitive to fire, but tolerant of limited moisture availability, and had a uniform distribution pattern associated with vegetation mat size. In contrast,most terrestrial species (subtribe Habenariinae) were not impacted by fire, but were limited to slopes with high water seepage, and had a clumped distribution pattern. The results suggest varying ecological niches between orchid subtribes, and among species, occurring on shared substrate. Within the larger area, we also compared three inselbergs with different fire disturbance history. One site with potential for lightning based fires, but absence of anthropogenic fires, had the greatest diversity (subtribes, genera, and species) of orchids and the highest occurrence of species restricted to a single site. For land management purposes it is inappropriate to assume that inselberg specific orchids will have the same response to environmental stressors. Angraecinae orchids are especially at risk from human associated fire disturbance and should be regarded as indicators for future conservation efforts.
