Field-scale observations of a transient geobattery resulting from natural attenuation of a crude oil spill Field-scale observations of a transient geobattery resulting from natural attenuation of a crude oil spill
We present evidence of a geobattery associated with microbial degradation of a mature crude oil spill. Self-potential measurements were collected using a vertical array of nonpolarizing electrodes, starting at the land surface and passing through the smear zone where seasonal water table fluctuations have resulted in the coating of hydrocarbons on the aquifer solids. These passive...

Community stability within the St. Marys River fish community: Evidence from trawl surveys Community stability within the St. Marys River fish community: Evidence from trawl surveys
A trawl survey was conducted in the Saint Marys River during 2010–2011 and we compared our results to a prior trawl survey conducted during 1979–1983 to look for long-term changes in the fish community, especially in terms of changes induced by invasive species. We found no substantive temporal differences in fish density, fish biomass, or fish diversity; lower trawl biomass during 2010...

Implanting 8-mm passive integrated transponder tags into small Brook Trout: Effects on growth and survival in the laboratory Implanting 8-mm passive integrated transponder tags into small Brook Trout: Effects on growth and survival in the laboratory
Passive integrated transponder (PIT) tags are commonly used to investigate relationships between individual fish and their environment. The recent availability of smaller tags has provided the opportunity to tag smaller fish. In this study, we implanted 8-mm PIT tags into small Brook Trout Salvelinus fontinalis (35–50 mm FL; 0.35–1.266 g) and compared tag retention, growth rates, and...

A decade of insights into grassland ecosystem responses to global environmental change A decade of insights into grassland ecosystem responses to global environmental change
Earth’s biodiversity and carbon uptake by plants, or primary productivity, are intricately interlinked, underlie many essential ecosystem processes, and depend on the interplay among environmental factors, many of which are being changed by human activities. While ecological theory generalizes across taxa and environments, most empirical tests of factors controlling diversity and...

2016 status of the Lake Ontario Lower Trophic levels 2016 status of the Lake Ontario Lower Trophic levels
Significant Findings for Year 2016: 1) Offshore spring total phosphorus (TP) in 2016 was 6.2 μg/L, higher than 2014 and 2015 (4.0 and 4.2 μg/L); there was no significant decline 2001 - 2016. Offshore soluble reactive phosphorus (SRP) was very low in 2016; Apr/May – Oct mean values were

A global threats overview for Numeniini populations: synthesising expert knowledge for a group of declining migratory birds. A global threats overview for Numeniini populations: synthesising expert knowledge for a group of declining migratory birds.
The Numeniini is a tribe of 13 wader species (Scolopacidae, Charadriiformes) of which seven are Near Threatened or globally threatened, including two Critically Endangered. To help inform conservation management and policy responses, we present the results of an expert assessment of the threats that members of this taxonomic group face across migratory flyways. Most threats are...

Five-year external reviews of the eight Department of Interior Climate Science Centers: Alaska Climate Science Center Five-year external reviews of the eight Department of Interior Climate Science Centers: Alaska Climate Science Center
This report primarily addresses the first two purposes of the review while providing comments on the third as identified by the science review team (SRT). A separate report of recommendations for the recompetition, based upon compiled observation from all three reviews conducted in 2016, was submitted to NCCWSC on April 15, 2016 to assist with the development of recompetition documents...

Field study suggests that sex determination in sea lamprey is directly influenced by larval growth rate Field study suggests that sex determination in sea lamprey is directly influenced by larval growth rate
Sex determination mechanisms in fishes lie along a genetic-environmental continuum and thereby offer opportunities to understand how physiology and environment interact to determine sex. Mechanisms and ecological consequences of sex determination in fishes are primarily garnered from teleosts, with little investigation into basal fishes. We tagged and released larval sea lamprey...

Effects of the biopesticide Zequanox® on reproduction and early development of the fathead minnow (Pimephales promelas) Effects of the biopesticide Zequanox® on reproduction and early development of the fathead minnow (Pimephales promelas)
The biopesticide, Zequanox®, is registered for dreissenid mussel control in open water systems in the United States. Previous toxicity trials with nontarget organisms, including several young-of-the-year fish species and invertebrates, demonstrated selectivity of Zequanox for dreissenid mussels, but data are lacking on the treatment-related effects on reproduction and early life stage...

Species composition, timing, and weather correlates of autumn open-water crossings by raptors migrating along the East-Asian Oceanic Flyway Species composition, timing, and weather correlates of autumn open-water crossings by raptors migrating along the East-Asian Oceanic Flyway
Raptor migration rarely involves long-distance movements across open oceans. One exception occurs along the East-Asian Oceanic Flyway. We collected migration data at two terrestrial hawkwatch sites along this flyway to better understand open-ocean movements along this largely overwater corridor. At the northern end of the Philippines, at Basco on the island of Batan, we recorded 7587...
