Area closures allow fish and shellfish populations associated habitats to recover from the effects of fishing. Determining appropriate duration rotational management for Atlantic sea scallop (Placopecten magellanicus) fishery requires information on both recovery subsequent harvest resiliency marine benthic ecosystems conservation objectives. Here, fishing communities northern edge Georges Bank...

This study aimed to gain new insights into urban hydrological balance (in particular, the evaporation from paved surfaces). Hourly data were obtained simultaneously two high-resolution weighable lysimeters. These lysimeters are covered in pavement sealing types commonly used for sidewalks Berlin, namely cobble-stones and concrete slabs. A paired experiment field conditions is designed determine...

We present a granulometric study of emerged pebble beach ridges in the Fort Williams Point, Greenwich Island, Antarctic Peninsula. We studied 8 beach ridges from the shore up to 13.5 m above current sea level. The beach ridges are made of volcanic material from the surrounding relief, but also include glacially transported gneiss and granodiorite pebble and cobble. Based on granulometric distri...

[1] The present study examines variations in the reference shear stress for bed load transport (tr) using coupled measurements of flow and bed load transport in 45 gravel-bed streams and rivers. The study streams encompass a wide range in bank-full discharge (1–2600 m/s), average channel gradient (0.0003–0.05), and median surface grain size (0.027–0.21 m). A bed load transport relation was form...

Delaware (DE) Bay, in the northeastern USA, has long been recognized as a hotspot for avian influenza A virus (IAV); every spring, this coastal region serves as a brief stopover site for thousands of long-distance migrating shorebirds, en route to breeding grounds in the Arctic. During these stopovers, IAV has been consistently recovered from ruddy turnstones (Arenaria interpres) that are likel...

The optimisation of haematopoietic stem and progenitor cell expansion is on demand in modern cell therapy. In this work, haematopoietic stem/progenitor cells (HSPCs) have been selected from unmanipulated cord blood mononuclear cells (cbMNCs) due to adhesion to human adipose-tissue derived stromal cells (ASCs) under standard (20%) and tissue-related (5%) oxygen. ASCs efficiently maintained viabi...

Simple transport models predict that the distance organisms drift downstream in rivers is determined by their settling velocity (ws), the release height (zr), and the stream velocity (U). Unfortunately, empirical evidence is lacking on whether and how factors such as ws affect mussel larvae dispersion in rivers under natural turbulent conditions. The main goal of this study was to examine how U...

Two native, stream-associated amphibians are found in coastal streams of the west coast of North America, the tailed frog and the coastal giant salamander, and each interacts with stream insects in contrasting ways. For tailed frogs, their tadpoles are the primary life stage found in steep streams and they consume biofilm from rock surfaces, which can have trophic and non-trophic effects on str...
