Climate Change

Climate change could pose a number of problems for amphibians, and can be grouped into 4 main categories:

1) changes in the local environments they inhabit (soil temperature, prey availability)

2) changes in the phenology (timing) of activities such as foraging and breeding

3) changes in the presence of pathogens and exotic species

4) interactions of climate with...

Amphibian Diseases

Amphibian diseases are emerging as an important concern in the study of amphibian declines. While NE ARMI does not focus intensively on amphibian disease research, the issue plays an important role in our activities.

Deep-Sea Coral Ecosystems

Although out of sight to most, a diverse array of coral species thrive deep below the photic zone off U.S. coasts and worldwide. Deep-sea corals can be found at depths greater than 50m, where sunlight does not penetrate. Similar to shallow-water corals, larger sea fan and reef-forming deep-sea coral species create structural complexity in the deep sea, attracting fishes and invertebrates that...

305b Groundwater Quality Monitoring in New York

Relatively little data describing the quality of groundwater in New York State exist, yet groundwater is used as a source of drinking water by approximately one quarter of the population of the state. The objective of the 305(b) groundwater quality monitoring project is to quantify and report on ambient groundwater quality from bedrock and glacial-drift aquifers in upstate New York.

National Assessment of Coastal Vulnerability to Sea Level Rise

The original national coastal vulnerability index (CVI) assessment was motivated by expected accelerated sea-level rise (SLR) and the uncertainty in the response of the coastline to SLR. This research was conducted between 1999 and 2001, and is currently being updated using new data sources and methodology. This original study was part of the ...

100-kyr paced climate change in the Pliocene warm period, Southwest Pacific

The mid to late Pliocene (~4.2-2.8 Ma.) represents an experiment in climate sensitivity to orbital pacing in which nearly all continental ice was confined to the Southern Hemisphere. Most studies have emphasized the dominant role of obliquity in determining changes in ice volume and temperature at this time, although most records come from the...

Focus areas for data acquisition for potential domestic sources of critical minerals—Rare earth elements

Rare earth elements (REEs) are critical mineral commodities for the United States. In response to a need for information on potential domestic sources of REEs in mineral deposits, the U.S. Geological Survey (USGS) identified broad focus areas throughout the conterminous United States and Alaska as a guide for selecting new geoscience research...

Molecular characterization of Bathymodiolus mussels and gill symbionts associated with chemosynthetic habitats from the U.S. Atlantic margin

Mussels of the genus Bathymodiolus are among the most widespread colonizers of hydrothermal vent and cold seep environments, sustained by endosymbiosis with chemosynthetic bacteria. Presumed species of Bathymodiolus are abundant at newly discovered cold seeps on the Mid-Atlantic continental slope, however morphological taxonomy is challenging, and...

Functional divergence of thyrotropin beta-subunit paralogs gives new insights into salmon smoltification metamorphosis

Smoltification is a metamorphic event in salmon life history, which initiates downstream migration and pre-adapts juvenile salmon for seawater entry. While a number of reports concern thyroid hormones and smoltification, few and inconclusive studies have addressed the potential role of thyrotropin (TSH). TSH is composed of a α-subunit common to...

Two hundred adult white sucker (Catostomus commersonii), age 3 years and older, were collected from the lower Sheboygan River Area of Concern in 2017, during the spring spawning run. Fish were euthanized, weighed, and measured, and any visible abnormalities were documented. Pieces of raised skin lesions as well as five to eight pieces of liver...

Widespread global peatland establishment and persistence over the last 130,000 y

Glacial−interglacial variations in CO2 and methane in polar ice cores have been attributed, in part, to changes in global wetland extent, but the wetland distribution before the Last Glacial Maximum (LGM, 21 ka to 18 ka) remains virtually unknown. We present a study of global peatland extent and carbon (C) stocks through the last glacial...
