Recruitment, Growth and Mortality of an Antarctic Hexactinellid Sponge, Anoxycalyx joubini

Creator:: Dayton, Paul K., Kim, Stacy, Jarrell, Shannon C., Oliver, John S., Hammerstrom, Kamille, Fisher, Jennifer L., O'Connor, Kevin, Barber, Julie S., Robilliard, Gordon, Barry, James, Thurber, Andrew R., and Conlan, Kathy
Abstract:: Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...

Eocene and not Cretaceous origin of spider wasps: Fossil evidence from amber

Creator:: Rodriguez, Juanita, Waichert, Cecilia, von Dohlen, Carol D., Poinar, George, Jr., and Pitts, James P.
Abstract:: Spider wasps had long been proposed to originate in the mid-Cretaceous based on the Burmese amber fossil Bryopompilus interfector Engel and Grimaldi, 2006. We performed a morphological examination of this fossil and determined it does not belong to Pompilidae or any other described hymenopteran family. Instead, we place it in...

Long-term individual sighting history database: an effective tool to monitor satellite tag effects on cetaceans

Creator:: Gendron, D., Serrano, I. Martinez, de la Cruz, A. Ugalde, Calambokidis, J., and Mate, B.
Abstract:: During the last 3 decades, tagging technology has been used to study different aspects of cetacean ecology. Tags implanted in animal’s blubber, muscle and surrounding tissue have produced successful results, providing information on long-term movements. However, apart from the reports of ‘divots’ (depressions) and swelling at the tag sites in...

O. C.
Abstract:: The seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and...

Abstract:: The recovery of a 1.5 million yr long ice core from Antarctica represents a keystone of our understanding of Quaternary climate, the progression of glaciation over this time period and the role of greenhouse gas cycles in this progression. Here we tackle the question of where such ice may still...

Comparison of fixatives and fixation time for PCR detection of Mycobacterium in zebrafish Danio rerio

Creator:: Peterson, Tracy S., Kent, Michael L., Ferguson, Jayde A., Watral, Virginia G., and Whipps, Christopher M.
Abstract:: Mycobacteriosis is a common disease of laboratory zebrafish Danio rerio. Different infection patterns occur in zebrafish depending on mycobacterial species. Mycobacterium marinum and M. haemophilum produce virulent infections associated with high mortality, whereas M. chelonae is more widespread and is not associated with high mortality. Identification of mycobacterial infections to...

Quantifying dissipative beach and vegetated dune morphology with multiple aerial photography systems

Creator:: Conlin, Matthew P.
Abstract:: Sand dunes provide coastal communities critical protection from flooding and erosion, as well as a habitat for a range of species- some threatened or endangered. As such, it is of importance to develop a quantitative understanding of the processes through which these systems evolve at a variety of temporal and...

Reproductive phase locking of mosquito populations in response to rainfall frequency

Creator:: Shaman, Jeffrey and Day, Jonathan F.
Abstract:: The frequency of moderate to heavy rainfall events is projected to change in response to global warming. Here we show that these hydrologic changes may have a profound effect on mosquito population dynamics and rates of mosquito-borne disease transmission. We develop a simple model, which treats the mosquito reproductive cycle...
