Linking multidimensional functional diversity to quantitative methods: a graphical hypothesis-evaluation framework

Creator:: Boersma, Kate S., Dee, Laura E., Miller, Steve J., Bogan, Michael T., Lytle, David A., and Gitelman, Alix I.
Abstract:: Functional trait analysis is an appealing approach to study differences among biological communities because traits determine species' responses to the environment and their impacts on ecosystem functioning. Despite a rapidly expanding quantitative literature, it remains challenging to conceptualize concurrent changes in multiple trait dimensions (“trait space”) and select quantitative functional...

Natural-Channel-Design Restorations that Changed Geomorphology Have Little Effect on Macroinvertebrate Communities in Headwater Streams

Creator:: Ernst, Anne G., Warren, Dana R., and Baldigo, Barry P.
Abstract:: Stream restorations that increase geomorphic stability can improve habitat quality, which should benefit selected species and local aquatic ecosystems. This assumption is often used to define primary restoration goals; yet, biological responses to restoration are rarely monitored or evaluated methodically. Macroinvertebrate communities were inventoried at 6 study reaches within 5...

Dynamic seascapes : a quantitative framework for scaling pelagic ecology and biogeochemistry

Creator:: Kavanaugh, Maria T.
Abstract:: Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

Interannual variations in phytoplankton community structure in the northern California Current during the upwelling seasons of 2001−2010

Creator:: Du, Xiuning, Peterson, William, and O'Higgins, Linda
Abstract:: Phytoplankton species were enumerated from 72 samples collected biweekly during the upwelling season (May to August) of 2001−2010 to test for effects of interannual variations in upwelling and decadal basin-scale variability on phytoplankton species composition and community structure. Cluster analysis of phytoplankton community structure identified 7 groups; 1 group was...

Spatial Allocation of Fishing Effort Discriminated By Fishing Gear in A Multi-Species Fleet

Creator:: Monroy, Carmen, Salas, Silvia, and Bello, Javier
Abstract:: It is generally assumed that multi-species fleets operate in a generalist fashion, given diversity of gears employed. An analysis of gears, species and spatial fishing effort allocation can give an indication if those patters are indeed common in these types of fleets. In this paper we examine the fishing operations...

Microbial distributions detected by an oligonucleotide microarray across geochemical zones associated with methane in marine sediments from the Ulleung Basin

Creator:: Briggs, Brandon R., Graw, Michael, Brodie, Eoin L., Bahk, Jang-Jun, Kim, Sung-Han, Hyun, Jung-Ho, Kim, Ji-Hoon, Torres, Marta, and Colwell, Frederick S.
Abstract:: The biogeochemical processes that occur in marine sediments on continental margins are complex; however, from one perspective they can be considered with respect to three geochemical zones based on the presence and form of methane: sulfate-methane transition (SMTZ), gas hydrate stability zone (GHSZ), and free gas zone (FGZ). These geochemical...

Parasite communities indicate effects of cross-shelf distributions, but not mesoscale oceanographic features on northern California Current mid-trophic food web

Creator:: Jacobson, Kym C., Baldwin, Rebecca E. B., and Reese, Douglas C.
Abstract:: Mesoscale physical oceanographic features, such as jets and eddies, can influence the structure of marine ecosystems. We used trophically transmitted parasite communities of pelagic fishes in the northern California Current to examine effects of physical oceanographic features on pelagic ecosystem structure. We tested the hypotheses that (1) oceanographic features associated...

Integrated assessment of the coastal fishery production systems in French Guiana

Creator:: Ahad Cisse, Abdoul, Blanchard, Fabian, and Guyader, Olivier
Abstract:: As many cases of tropical small-scale fisheries, the French Guiana coastal fishery is characterized by the high fish biodiversity of its ecosystem, the weak selectivity of the fleets exploiting the resources, the heterogeneity of the vessels in term of size and fishing techniques. The traditional tools used to manage fisheries...

Using local climate to explain temporal variation in rare plant populations

Creator:: Pfingsten, Ian A.
Abstract:: Increased temperatures due to anthropogenic-induced climate change may raise the threat of extinction for taxa with sessile life histories (e.g., plants) in the near future. Linking climate change models to demographic models may provide useful insights into the potential effects of environmental changes on rare plants, and therefore aid in...

Management trade-off between aboveground carbon storage and understory plant species richness in temperate forests

Creator:: Burton, Julia I., Ares, Adrian, Olson, Deanna H., and Puettmann, Klaus J.
Abstract:: Because forest ecosystems have the capacity to store large quantities of carbon (C), there is interest in managing forests to mitigate elevated CO[subscript 2] concentrations and associated effects on the global climate. However, some mitigation techniques may contrast with management strategies for other goals, such as maintaining and restoring biodiversity....
