Data tables in support of manuscript "δ13C and δ15N in the Endangered Kemp's Ridley Sea Turtle Lepidochelys kempii After the Deepwater Horizon Oil Spill"
The Deepwater Horizon explosion and oil spill in April 2010 released 3.19 million barrels of MC252 crude oil into important foraging areas of the endangered Kemps ridley sea turtle (Lepidochelys kempii; Lk) in the northern Gulf of Mexico (GoM). We measured delta-13 C and delta-15 N in scute biopsy samples from Lk that nested in Texas during 2010-12. Satellite-tracked Lk returned to traditional nor

Vegetation community recovery on restored bottomland hardwood forests in northeast Indiana, USA
Vegetation communities in restored bottomland hardwood forests in northeast Indiana were studied 6–21 years after restoration to assess progress toward restoration objectives. The study focused on four sites that were restored to compensate for resource injuries after contaminant releases. The restored sites were compared with four reference-site conditions, including crops (prerestoration conditi

Efficient mammal biodiversity surveys for ecological restoration monitoring
Efficient biodiversity surveys are critical for successful restoration monitoring and management. We studied the effect of varying sampling effort on the observed species richness of surveys of small mammals (trapping transects), bats (passive acoustic detection), and medium to large mammals (trail cameras). Field studies provided mammalian biodiversity data for 4 bottomland hardwood restoration s

Visitor use and activities detected using trail cameras at forest restoration sites
We used trail cameras to monitor human visits and activities at two sites in northeast Indiana being restored to bottomland hardwood forests. These sites, managed as nature preserves, are close to cities, where trails and parking lots have been added for ease of access. In this study, trail cameras were successfully used to capture visitation rates and activity types. The two sites had median visi

Evaluation of Ziram as an oral toxic bait chemical for control of grass carp Ctenopharyngodon idella
The grass carp, Ctenopharyngodon idella, is an invasive species in North America that has been recorded in 45 states with breeding populations in several major river basins. Established populations of grass carp have had cascading, negative effects on aquatic ecosystem structure and function. Oral piscicide baits have been examined as a potential method to manage invasive grass carp. Our goal was

Migration and energetics model predicts delayed migration and likely starvation in oiled waterbirds
Oil spills can inflict mortality and injury on bird populations; many of these deaths involve starvation resulting from thermoregulatory costs incurred by oiling of birds’ feathers. However, the fates and responses of sublethally oiled birds are poorly known. Due to this knowledge gap and the potential for birds to die far from the spill site, resource risk and injury assessors need tools to make

CYP1A protein expression and catalytic activity in double-crested cormorants experimentally exposed to Deepwater Horizon Mississippi Canyon 252 oil
Double-crested cormorants (Phalacrocorax auritus, DCCO) were orally exposed to Deepwater Horizon Mississippi Canyon 252 (DWH) oil to investigate oil-induced toxicological impacts. Livers were collected for multiple analyses including cytochrome P4501A (CYP1A) enzymatic activity and protein expression. CYP1A enzymatic activity was measured by alkoxyresorufin O-dealkylase (AROD) assays. Activities s

Efficient mammal biodiversity surveys for ecological restoration monitoring
Efficient biodiversity surveys are critical for successful restoration monitoring and management. We studied the effect of varying sampling effort on the observed species richness of surveys of small mammals (trapping transects), bats (passive acoustic detection), and medium to large mammals (trail cameras). Field studies provided mammalian biodiversity data for 4 bottomland hardwood restoration s

Evaluation of Ziram as an oral toxic bait chemical for control of grass carp Ctenopharyngodon idella
The grass carp, Ctenopharyngodon idella, is an invasive species in North America that has been recorded in 45 states with breeding populations in several major river basins. Established populations of grass carp have had cascading, negative effects on aquatic ecosystem structure and function. Oral piscicide baits have been examined as a potential method to manage invasive grass carp. Our goal was

Migration and energetics model predicts delayed migration and likely starvation in oiled waterbirds
Oil spills can inflict mortality and injury on bird populations; many of these deaths involve starvation resulting from thermoregulatory costs incurred by oiling of birds’ feathers. However, the fates and responses of sublethally oiled birds are poorly known. Due to this knowledge gap and the potential for birds to die far from the spill site, resource risk and injury assessors need tools to make
