Assessing the drivers of spatial variation in thermal forcing across a nearshore reef system and implications for coral bleaching
Assessing the drivers spatial variation thermal forcing across a nearshore reef system implications coral bleaching
2014/7/10
We examined the seasonal and spatial variability in the temperatures of nearshore reef waters over 19 months across Coral Bay at Ningaloo Reef, Western Australia. Local deviations in the mean daily te...
Mitochondrial sequence variation suggests extensive cryptic diversity within the Western Palearctic Daphnia longispina complex
Mitochondrial sequence variation extensive cryptic diversity the Western Palearctic Daphnia longispina complex
2014/4/2
We report on a discovery of six divergent lineages within the European Daphnia longispina complex from various localities in central to northeast Europe. The levels of divergence from well-known speci...
Taxon- and vector-specific variation in species richness and abundance during the transport stage of biological invasions
Taxon- and vector-specific variation species richness abundance the transport stage of biological invasions
2014/4/2
Recent empirical and statistical evidence suggest that propagule pressure (i.e., number of individuals introduced per event, and the number and frequency of events) and colonization pressure (i.e., nu...
Large-scale geographical variation in prokaryotic abundance and production in meso- and bathypelagic zones of the central Pacific and Southern Ocean
Large-scale geographical variation prokaryotic abundance production meso- and bathypelagic zones central Pacific Southern Ocean
2014/4/2
Heterotrophic production and abundance of prokaryotes (i.e.,BacteriaandArchaea) in meso- (200–1000 m) and bathypelagic (.1000 m) zones were measured at 31 stations along meridional transects of the ce...

Climate variation, carbon flux, and bioturbation in the abyssal North Pacific
Climate variation carbon flux bioturbation abyssal North Pacific
2014/4/17
We hypothesized that seasonal and interannual climate-mediated changesin particulate organic carbon (POC) flux would affect bioturbation and ultimately the sequestration of organic carbon in the deep ...
Mitochondrial and Nuclear Genetic Variation across Calving Lagoons in Eastern North Pacific Gray Whales (Eschrichtius robustus)
cetacean microsatellite population structure
2015/12/11
Accurate knowledge of population structure in cetaceans is critical for preserving and managing breeding habitat,
particularly when habitat is not uniformly protected. Most eastern gray whales return...
Regional variation in oceanographic conditions influences intertidal fish assemblage structure
Regional variation oceanographic conditions influences intertidal fish
2014/4/17
I investigated the relationship between regional variation in habitat and oceanographic conditions and the
population and assemblage structure of intertidal fishes (the sculpins Clinocottus globiceps...
Annual recruitment of three species of tide-pool fishes is driven by variation in springtime coastal hydrodynamics
Annual recruitment variation springtime coastal hydrodynamics
2014/4/17
Using an 18-yr time series of annual recruitment of three tide-pool fishes, Clinocottus globiceps, Clinocottus
embryum, and Oligocottus maculosus, we investigated the relationship between recruitment...
Variation in the transfer of energy in marine plankton along a productivity gradient in the Atlantic Ocean
the transfer of energy marine plankton productivity gradient Atlantic Ocean
2014/5/5
Plankton play a key role in oceanic carbon flux as the primary biological mechanism for the sequestration of carbon out of the atmosphere into surface waters. The transfer of energy between phytoplank...
Temporal and spatial variation of sulfide invasion in eelgrass (Zostera marina) as reflected by its sulfur isotopic composition
Temporal and spatial variation sulfide invasion in eelgrass sulfur isotopic composition
2014/5/5
Temporal and spatial variation of δ34S, total sulfur (TS) concentration, and elemental sulfur concentration (S0) in leaves, roots, and rhizomes of Zostera marina was followed between June 2002 and May...
Spatial variation of nitrogen fixation in lakes of the northern Great Plains
Spatial variation nitrogen fixation the northern Great Plains
2014/5/4
Cyanobacterial blooms are a regular feature of lakes in central North America, but little is known of their importance to the nitrogen (N) cycle and nutrition of aquatic food webs. We hypothesized tha...
Spring bloom development, genetic variation, and population succession in the planktonic diatom Ditylum brightwellii
Spring bloom development genetic variation population succession planktonic diatom Ditylum brightwellii
2014/5/4
We determined spatial and temporal variation in abundance, distribution, and genetic composition of the planktonic marine diatom Ditylum brightwellii in 21 water samples collected between February and...
Consequences of large temporal variability of zooplankton d15N for modeling fish trophic position and variation
Consequences of large temporal variability of zooplankton d15N modeling fish trophic position variation
2014/5/13
We use a temporal integration model (TIM) to determine how estimates of trophic variation, using δ15N, depend on consumer growth dynamics and temporal isotopic variation (δ15N) of food sources. Consum...
Temporal and spatial variation in the d15N and d13C of coral tissue and zooxanthellae in Montastraea faveolata collected from the Florida reef tract

2014/5/9
Tissues were collected from Montastraea faveolata at five locations on the Florida Reef tract representing both nearshore and offshore environments. The tissue and zooxanthellae were removed from the ...
