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...

Harmful Algae Blooms (HABs)

Cyanobacterial harmful algal blooms (HABs) are increasingly a global concern because HABs pose a threat to human and aquatic ecosystem health and cause economic damages. Toxins produced by some species of cyanobacteria (called cyanotoxins) can cause acute and chronic illnesses in humans and pets. Aquatic ecosystem health also is affected by cyanotox­ins, as well as low dissolved oxygen...

Future directions to escalate benefits of stepping-stone approach for conservation translocations

Through a reintroduction case study on the critically endangered Vancouver Island marmot (Marmota vancouverensis), we introduced a ‘stepping-stone’ approach which utilizes the transition of released individuals among populations to maximize demographic growth potential (Lloyd et al. 2019). We greatly appreciate and hereby reflect on the...

Coelomic disorders of fishes

Dropsy is a commonly applied term for coelomic distention due to ascites, or the effusion and collection of fluid freely throughout the coelomic cavity. Dropsy, or ascites, is generally a sign of another ongoing disease process, oftentimes one that is multisystemic and impacting coelomic organs and tissues. Dropsy may be caused by a variety of...

Perfluoroalkyl contaminant exposure in tree swallows nesting at Clarks Marsh, Oscoda, Michigan, USA

A site in north eastern Michigan, Oscoda Township, has some of the highest recorded exposure in birds to perfluorinated substances (PFASs) in the U.S. Some egg and plasma concentrations at that location exceeded the lowest reproductive effect threshold established for two avian laboratory species. The objectives of this study were to determine...

Seasonal, tidal, and geomorphic controls on sediment export to Amazon River tidal floodplains

Mainstem–floodplain material exchange in the tidal freshwater reach of ma jor rivers may lead to significant sequestration of riverine sediment, but this zone remains understudied compared to adjacent fluvial and marine environ ments. This knowledge gap prompts investigation of floodplain-incising tidalchannels found along the banks of tidal...

Detecting the undetectable: Characterization, optimization, and validation of an eDNA detection assay for the federally endangered dwarf wedgemussel, Alasmidonta heterodon (Bivalvia: Unionoida)

Environmental (e)DNA assays are valuable tools for monitoring presence and distribution of cryptic species. Like many freshwater mussels, the dwarf wedgemussel, Alasmidonta heterodon numbers have dwindled and its range has diminished. As of its listing in 1993, only 10 to 20 locations were known to persist of the 70 Atlantic slope locations known...

Pathways to strategic communication for biodiversity conservation: Response to “Hearing ourselves (and acting in consequence): A commentary on Bekessy et al. from a bird-handling environmental education perspective”

Central to discussions about the merits of ecosystem services as a communication strategy is the degree to which it represents a strategic and effective approach to advance biodiversity conservation. There is increasing recognition that many conservation communication efforts can be more strategic (e.g. Kusmanoff et al. 2016).

Functional variation at an expressed MHC class IIß locus associates with Ranavirus infection intensity in larval anuran populations

Infectious diseases are causing catastrophic losses to biodiversity globally. Iridoviruses in the genus Ranavirus are among the leading causes of amphibian disease-related mortality. Polymorphisms in major histocompatibility complex (MHC) genes are significantly associated with variation in amphibian susceptibility to pathogens. MHC genes encode...

Spatial capture–recapture for categorically marked populations with an application to genetic capture–recapture

Recently introduced unmarked spatial capture–recapture (SCR), spatial mark–resight (SMR), and 2‐flank spatial partial identity models (SPIMs) extend the domain of SCR to populations or observation systems that do not always allow for individual identity to be determined with certainty. For example, some species do not have natural marks that can...

Quaternary eolian sediments and Carolina Bays of the U.S. Atlantic Coastal Plain province

Under modern conditions, the Atlantic Coastal Plain province of the eastern United States is not very conducive to widespread eolian sediment mobilization because of a humid and mesothermal climate, relatively low mean surface wind velocities (~1–3 m/sec), and relatively dense vegetation. LiDAR data, however, have revealed the presence of...
