Fish Behavior

Recent discoveries of the extent of sturgeon movement in the Gulf of Maine combined with relicensing and water use issues in the Connecticut River demand closer evaluation of shortnose and Atlantic sturgeon migration and behavior patterns. Through field collaboration with state, federal, university and military institutions LSC-Conte scientists work to define the significance of pre-spawning...

The West Brook Story

Natural systems, like rivers and streams, are remarkably complex, with many interacting parts. Data visualization tools make understanding and communicating complex ecological processes easier. Effective visualizations help users learn about patterns in data and how models work. Interactive visualizations are particularly useful, as they let users explore data and develop a personal...

Conservation Engineering

Engineering has an important role to play in the conservation of migratory fish species.  As a result of anthropogenic development on river systems, full and partial barriers to fish movement commonly exist in watersheds worldwide.  There is an estimated 2.5 million barriers to fish migration in the United States alone.  These barriers typically consist of small to large size dams, culverts,...

Lake Ontario Flood Monitoring and Mapping

Problem– Lake Ontario experienced period-of-record (1918-2017) maximum monthly average water levels during May through July 2017. NOAA lake gages recorded instantaneous peaks-of record, 249.2 at Olcott, 249.1 at Rochester, and 249.0 at Oswego and St. Vincent. These high water levels along with wind-generated waves caused flooding of thousands of residences and businesses and the erosion of...

Native Bee Inventory and Monitoring Lab

The USGS Native Bee Inventory and Monitoring Program designs and develops large and small scale surveys for native bees. As part of that program we also develop identification tools and keys for native bee species. One aspect of creating those tools is creating accurate and detailed pictures of native bees and the plants and insects they interact with.

Fish Ecology

Our goal is to identify the factors that govern population dynamics. Emphasis is on an integrative approach, combining field and laboratory studies to provide data for mathematical models of ecological and evolutionary dynamics. We focus on the fish that live in streams; how environmental variation, barriers to movement, and landscape characteristics influence changes in abundance over time...

Fish Passage Hydraulic Flume

Many existing upstream and downstream fish passage structure designs (fishways, culverts, screens, downstream bypasses, etc.) function poorly or only for a narrow range of species or environmental conditions. Agencies currently seek improved or new designs that pass a broader range of species with increased efficiency and reliability, under a wider range of hydraulic operating conditions, and...

Fish Biomechanics

Biomechanics is the study of mechanical laws relating to the movement of living organisms. In regards to fish, biomechanics pertains to the body shape of different species and the various structures of fish muscles, fins, etc. The biomechanics of a fish impact its swimming performance which in turn affects its ability to surpass barriers to movement. Understanding the biomechanical drivers of...

Effects of Network Structure on Stream Salamanders

The role of stream network structure in driving salamander population dynamics needs more attention.  Although several studies have examined the effects of stream habitat and interspecific interactions on salamander populations, the role of the spatial structure of stream networks in mediating population processes for stream salamanders is poorly understood.  However, the role of stream...

Managing Habitat for Amphibians

Monitoring programs worldwide focus on estimation of trends in populations, often with an implicit expectation that identification of a trend will result in smart decisions as to how to respond (via management).  Though many researchers investigating the patterns and causes of amphibian declines have focused on estimation and detection of population trends, we take a different approach.  We...

Evidence for geographic variation in life-cycle processes affecting phenology of the Lyme disease vector Ixodes scapularis (Acari: Ixodidae) in the United States

The seasonal activity pattern of immature Ixodes scapularis Say (Acari: Ixodidae) varies geographically in the United States, which may affect the efficiency of transmission cycles of pathogens transmitted by this species. To study the factors that determine seasonality, a multiyear study at seven sites across the geographic range of...

Endangered species recovery: A resource allocation problem

Many nations have laws to identify and protect imperiled species and their ecosystems. In the United States, actions taken under the Endangered Species Act (ESA) have prevented many extinctions, but few listed species have recovered to the point where they can have the ESA protections removed (1, 2). One reason for this [among many (3)] is a...

Investigating home range, movement pattern, and habitat selection of Bar-headed Geese during breeding season at Qinghai Lake, China

The Bar-headed Goose is an important species in Asia, both culturally and ecologically. While prior studies have shown Qinghai Lake supports one of the largest breeding areas for Bar-headed Geese, little is known regarding the species movement ecology during the breeding season. In this study, we examined Bar-headed Goose home range size within...

The alluvial diamond deposits of the Central African Republic (CAR) are mined almost exclusively by way of informal artisanal and small-scale mining (ASM) methods. ASM sites range in diameter from a few meters to 30 meters or more, and are typically excavated by crews of diggers using hand tools, sieves, and jigs. CAR’s reported annual production...
