Terminal Phase Feeding Call of the Hawaiian Hoary Bat

Christopher Todd — Thu, 16 May 2013 00:00:00 EDT

When bats detect an insect from returned echolocation calls they rapidly increase the pulse rate and raise the frequency of calls in order to gather more information on the insect including location. These calls emitted right before a bat closes in on an insect are called terminal phase calls or "feeding buzzes". The frequency is well above human hearing capabilities at 65 khz and bats will emit some 200 calls per second.

Evening Frog Calls

Hardin Waddle — Fri, 10 May 2013 00:00:00 EDT

The Big Squeeze: Pythons and Mammals in Everglades National Park

Marisa Lubeck — Mon, 27 Feb 2012 00:00:00 EDT

The wet, subtropical wilderness of Everglades National Park is home to a diversity of Floridian wildlife, but one invader is causing severe changes in these native animal populations. Many of the park’s mammals are declining dramatically as a result of invasive Burmese pythons, according to a recent study by U.S. Geological Survey scientists and partners. Mid-sized mammals such as foxes, rabbits, and raccoons that were previously populous in the Everglades are the most severely affected.

Culprit Identified: Fungus Causes Deadly Bat Disease

Marisa Lubeck — Wed, 26 Oct 2011 00:00:00 EDT

White-nose syndrome is a deadly disease in North American bats that has been spreading rapidly since its 2006 discovery in N.Y. State. Thus far, bat declines in the northeastern U.S. have exceeded 80%. For the first time, scientists with the U.S. Geological Survey and partner institutions have identified the cause of WNS as a fungus appropriately known as Geomyces destructans. The research, which was conducted at the USGS NWHC in Madison, Wisc., further demonstrates that the fungus can be spread through contact between individual bats during hibernation. USGS microbiologist David Blehert to discusses these significant findings.

Melanie Gade — Fri, 9 Sep 2011 00:00:00 EDT

Within the rivers, streams, and lakes of North America live over 200 species of freshwater mussels that share an amazing life history. To metamorphose from larvae to adult, the mussels must pass through a parasitic phase on the gills of freshwater fish. To trick the fish into accepting their larvae, female mussels have developed a complex array of lures and baits to attract and fool their unsuspecting hosts. This talk will explore the fascinating reproductive biology and ecological role of one of nature�s most sophisticated fishermen.

An Unseen World Beneath Our Feet - Caves, Sinkholes and Springs

Melanie Gade — Fri, 10 Jun 2011 00:00:00 EDT

Randall Orndorff, Director of the Eastern Geology and Paleoclimate Science Center, discusses how Karst affects daily life. Beneath a quarter of the United States are rock types that can dissolve to form caves, sinkholes and other features. Nearly every state has rock layers of limestone, gypsum, and other soluble rocks we call ‘karst’. Karst is important for many reasons. Almost half of the ground water used for drinking comes from karst aquifers, and karst regions such as the Shenandoah Valley are some of the most productive agricultural lands in the nation. However, the rock layers underneath karst dissolve easily, sometime creating sinkholes that can be a threat to life and property. Yet these soluble rock layers also yield some of the most beautiful and unique natural environments, found in many of our national and state parks.

Beyond Billions: Threatened Bats are Worth Billions to Agriculture

Marisa Lubeck — Thu, 31 Mar 2011 00:00:00 EDT

Insect-eating bats provide pest-control services that save the U.S. agriculture industry over $3 billion per year, according to a study released today in the journal Science. However, scientists with the U.S. Geological Survey, University of Pretoria in South Africa, University of Tennessee, and Boston University who contributed to the study warn that these valuable animals are at risk: Bat populations are declining due to fatalities associated with White-Nose Syndrome and wind turbines, which could lead to significant economic losses on U.S. farms. Paul Cryan, USGS scientist and an author of the report, discusses these findings.
