Body condition (i.e. relative mass after correcting for structural size) affects the behaviour of migrating birds, but how body migratory performance, timing and fitness is still largely unknown. Here, we studied effects on individual departure decisions, wind selectivity, flight speed migration a long-distance shorebird, red knot Calidris canutus rufa. By using automated VHF telemetry continental scale, knots' movements with unprecedented temporal resolution over 3-year period. Knots higher...
The upward migration of gas through marine sediments typically manifests itself as chimneys or pipes in seismic images and can lead to the formation cold seeps. Gas seepage is often linked morphological features like seabed domes, pockmarks, carbonate build-ups. In this context, sediment doming discussed be a precursor pockmark formation. Here, we present parametric echosounder, sidescan sonar, two-dimensional data from Opouawe Bank, offshore New Zealand, providing field evidence for doming....
Abstract Marine controlled source electromagnetic (CSEM) data have been collected to investigate methane seep sites and associated gas hydrate deposits at Opouawe Bank on the southern tip of Hikurangi Margin, New Zealand. The bank is located in about 1000 m water depth within stability field. are characterized by active venting typical fauna accompanied with patchy carbonate outcrops seafloor. Below seeps, migration pathways reach from below bottom‐simulating reflector (at around 380...
Abstract Atlantic salmon is often a focal species of restoration efforts throughout the north and it therefore an excellent case study for how best to design programmes address mitigate threats correct population declines. This perspective written promote work that has been accomplished towards populations synthesize we believe lessons can be used effectively support by management agencies restore populations. We reviewed where needed salmon, agreed on definitions three levels successful...
ABSTRACT Anthropogenic disturbance can degrade the quality of stopover sites for migratory shorebirds. We investigated potential effects pedestrian traffic and shellfishing on foraging shorebirds at a key site Monomoy National Wildlife Refuge (Monomoy Refuge), Massachusetts, USA. experimentally approached 11 species to quantify flight‐initiation distances (FID) found that age affected FID. Smaller Calidris sandpipers generally allowed pedestrians approach within 25 m before flushing, whereas...
Abstract Long-distance migrants are assumed to be more time-limited during the pre-breeding season compared post-breeding season. Although breeding-related time constraints may absent post-breeding, additional factors such as predation risk could lead that were previously underestimated. By using an automated radio telemetry system, we pre- and movements of long-distance migrant shorebirds on a continent-wide scale. From 2014 2016, deployed transmitters 1,937 individuals 4 shorebird species...
ABSTRACT For birds breeding in the Arctic, nest success is affected by timing of initiation, which partially determined local conditions such as snow cover. However, during non‐breeding season can carry over to affect breeding. We used tracking and data from 248 individuals 8 species subspecies Arctic‐breeding shorebirds estimate how initiation related like snowmelt phenology versus prior conditions, measured speed migration. Using path analysis, our global model showed that have similar...
Abstract The Chatham Rise is located offshore of New Zealand's South Island. Vast areas the are covered in circular to elliptical seafloor depressions that appear be forming through a bathymetrically controlled mechanism, as 2–5 km diameter found water depths 800–1100 m. High‐resolution P‐Cable 3D seismic data were acquired 2013 across one these depressions. depression interpreted mounded contourite. Our reveal several smaller buried (<20–650 m diameter) beneath contourite we interpret...
Surveys and banding records of Calidris canutus rufa indicate that Red Knots migrate mainly north south through Massachusetts, Delaware Bay, Virginia, winter in Florida South America. We fitted 40 adult with geolocators at Monomoy National Wildlife Refuge, during fall migration (2009), this paper report on the locations wintering along Atlantic coast United States eight recaptured knots. The knots' patterns varied: four birds wintered U.S. coast, rest went to Caribbean islands or northern...
Since the very first steps of space exploration, fungi have been recorded as contaminants, hitchhikers, or part missions' crews and payloads.Because can cause human disease are highly active decomposers, their presence in a space-linked context has source major concern given possible detrimental effects on structures.However, also be beneficial used for many applications.The exact not always clear they possess high adaptability plasticity, phenotypes genotypes undergo several changes under...
Abstract Takahe seep, located on the Opouawe Bank, Hikurangi Margin, is characterized by a well‐defined subsurface seismic chimney structure ∼80,500 m 2 in area. Subseafloor geophysical data based acoustic anomaly layers indicated presence of gas hydrate and free within structure. Reaction‐transport modeling was applied to porewater from 11 gravity cores constrain methane turnover rates benthic fluxes upper 10 m. Model results show that dynamics were highly variable due transport dissolution...
Emydoidea blandingii (Blanding's Turtle) is a species facing variety of anthropogenic threats that decrease population viability. We initiated project to establish new Blanding's Turtles on National Wildlife Refuge in Massachusetts using hatchlings obtained from nearby, robust donor population. released 440 headstarted individuals and 401 directly between 2007 2013 conducted multiple years post-release monitoring via aquatic trapping estimate survival. Between 2014 2021, we an additional 824...

Southward migrating Red Knots (Calidris canutus) were surveyed on Cape Cod, Massachusetts. Unique markers, including ones applied to birds in wintering areas North and South America, found. Northern southern-marked knots had different migration chronologies, plumage characteristics flight feather molt. from the two groups found have foods foraging habitats. Numbers of more than one year old increase mid-July mid-August, decline during late August then September–October. As numbers declined...
