Low-Flow Characteristics

Streamflow data collection and analysis are a necessary component of effective water resource management and planning.  Low-flow statistics are needed to safely allow withdraws from and discharges to surface waters in the State of New Jersey.  Operating streamflow gaging stations at every water use location would be ideal but is cost prohibitive. Statistics help extend the utility of available...

Pinelands Research

The New Jersey Pine Barrens, or Pinelands National Reserve (PNR), is a vast and unique ecosystem comprising approximately a 938,000-acre area of southern New Jersey. It spans portions of seven counties (Atlantic, Burlington, Camden, Cape May, Cumberland, Gloucester, and Ocean), and  all or part of 56 municipalities. It is home to dozens of rare plant and animal species, and the Kirkwood-...

New York State Flood Investigations

Flooding can be a serious problem in many parts of New York State. Information on floods and analyses of flood data are needed to aid in the design of bridges, culverts, dams, highways, and buildings, and for the prudent management of flood-prone areas. Documentation of floods and a more thorough understanding of flood hydrology and hydraulics will result in more effective management of flood...

Etching a worn band or an unreadable band

Most bands are made of an aluminum alloy and have unique numbers engraved. These numbers can wear off with time to the point that one number, few numbers, or the whole band becomes illegible. The time for a bird band to wear off greatly depends on the amount of time that bird species spends in the water. For instance, a band on a Mallard wears off one number in 8-10 years, while a band on a...

About Federal Bird Bands

There are three common types of bands used on wild birds in North America: (1) standard butt-end bands, (2) lock-on bands used on hawks and owls, (3) rivet bands used on eagles.

Mammal Collections

The North American mammal collection contains roughly 300,000 specimens and has grown little over the past 15 years. Geographic representation is excellent for most areas of North and Central America; the arid regions of the southwestern United States are particularly well represented. The standard preparation is the skin and skull of which there are about 190,000 specimens. Other major...

Bird Collections

The collection of North American birds housed in the National Museum of Natural History is one of outstanding quality. It totals about 370,000 specimens, including approximately 222,000 skins, 31,000 skeletons, 13,000 fluid-preserved, and about 26,500 egg sets and nests. Of the 3,949 specimens in the type collection, 2,120 specimens are holotypes of North American taxa. A major portion of the...

Marshes are the new beaches: Integrating sediment transport into restoration planning

Recent coastal storms and associated recovery efforts have led to increased investment in nature-based coastal protection, including restoration of salt marshes and construction of living shorelines. In particular, many of these efforts focus on increasing vertical elevation through sediment nourishment, where sediment is removed from the tidal...

Azimuthal seismic anisotropy of 70 Ma Pacific‐plate upper mantle

Plate formation and evolution processes are predicted to generate upper mantle seismic anisotropy and negative vertical velocity gradients in oceanic lithosphere. However, predictions for upper mantle seismic velocity structure do not fully agree with the results of seismic experiments. The strength of anisotropy observed in the upper mantle...

Water salinity and inundation control soil carbon decomposition during salt marsh restoration: An incubation experiment

Coastal wetlands are a significant carbon (C) sink since they store carbon in anoxic soils. This ecosystem service is impacted by hydrologic alteration and management of these coastal habitats. Efforts to restore tidal flow to former salt marshes have increased in recent decades and are generally associated with alteration of water inundation...

Size-specific apparent survival rate estimates of white sharks using mark-recapture models

For species that exist at low abundance or are otherwise difficult to study, it is challenging to estimate vital rates such as survival and fecundity and common to assume that survival rates are constant across ages and sexes. Population assessments based on overly simplistic vital rates can lead to erroneous conclusions. We estimated sex and...

Enhancement of primary production during drought in a temperate watershed is greater in larger rivers than headwater streams

Drought is common in rivers, yet how this disturbance regulates metabolic activity across network scales is largely unknown. Drought often lowers gross primary production (GPP) and ecosystem respiration (ER) in small headwaters but by contrast can enhance GPP and cause algal blooms in downstream estuaries. We estimated ecosystem metabolism across...

Explaining harvests of wild-harvested herbaceous plants: American ginseng as a case study

Wild-harvested plants face increasing demand globally. As in many fisheries, monitoring the effect of harvesting on the size and trajectory of resource stocks presents many challenges given often limited data from disparate sources. Here we analyze American ginseng (Panax quinquefolius L.) harvests from 18 states in the...

Critical review: Grand challenges in assessing the adverse effects of contaminants of emerging concern on aquatic food webs

Much progress has been made in the past few decades in understanding the sources, transport, fate, and biological effects of contaminants of emerging concern (CECs) in aquatic ecosystems. Despite these advancements, significant obstacles still prevent comprehensive assessments of the environmental risks associated with the presence of CECs. Many...

The missing dead: The lost role of animal remains in nutrient cycling in North American Rivers

While leaf litter, wood, and other plant remnants are known to play a central role in lotic ecosystems, animal remains (carcasses, bones, shells) have received less attention. We propose a simple classification scheme for animal remains in rivers based on origin (authochthonous vs. allochthonous) and frequency (pulsed vs continuous). We then...

The evolutionary consequences for seawater performance and its hormonal control when anadromous Atlantic salmon become landlocked

Populations of anadromous fish have become landlocked in relatively recent geological history (<14,000 years), but the evolutionary impacts of this altered lifecycle on traits underlying seawater performance have not been established. In order to examine the effects of relaxed selection on seawater traits, anadromous and landlocked Atlantic...

Paleocene–Eocene Thermal Maximum prolonged by fossil carbon oxidation

A hallmark of the rapid and massive release of carbon during the Palaeocene–Eocene Thermal Maximum is the global negative carbon isotope excursion. The delayed recovery of the carbon isotope excursion, however, indicates that CO2 inputs continued well after the initial rapid onset, although there is no consensus about the source of this...

Fieldwork on Florida Bay Islands

A USGS researcher conducts fieldwork on Buttonwood Key, an island in Florida Bay, to determine the impacts of Hurricane Irma. The storm left thick deposits of mud on the island, which are being measured, sampled and photographed.  Many of the islands in Florida Bay have open mudflats in the center, surrounded by mangroves on the perimeter.
