vTree vs Echo Meter Touch Bat Detector

Virginia Tech Tree Identification brings the award winning Virginia Tech digital dendrology material to your iPhone. It contains fact sheets for 969 woody plants from all over North America with an in-depth description, range map and thousands of color images of leaves, flowers, fruit, twigs, bark and form. Users can narrow the species list for any location in North America using the phone's GPS or any entered address or zip code. Basically the application can become "The Woody Plants of Where You Are Standing." For example, it can become "The Woody Plants of Southwestern Oregon," "The Woody Plants of Central Park," or "The Woody Plants of 37.108 lat., -80.452 long., elevation 2118." Users can further narrow the species list by answering a series of very simple tree attribute questions such as where the plant is growing, leaf shape, leaf arrangement, flower color or fruit type. The species list can also be narrowed by typing a keyword such as oak, Abies, red or palm. For example, if "oak" is typed, only oaks found in the defined area will be listed. A feature also allows you to send any tree related question to "Dr. Dendro," a tree expert in the Department of Forest Resources and Environmental Conservation at Virginia Tech. You can send a tree description or pictures of your plant and experts will help with identification. KEY FEATURES •969 woody plants from all over North America. •Over 6,400 color photographs of leaves, flowers, fruit, twig, bark, form, and range map for each species. •In depth description of all plant parts. •Narrows species list based on your location and elevation using the device's GPS or user entered location. •Search for species by a key word, e.g. maple. •Identify species by answering a series of simple questions. A picture is displayed showing what is being asked. •Navigate between species with a push of a button. •Send a tree question to "Dr. Dendro," a tree expert at Virginia Tech. VIRGINIA TECH TREE IDENTIFICATION DIGITAL MATERIAL Visit our web sites at: http://dendro.cnre.vt.edu Woody Plants in North America, 2012, Kendall/Hunt Publishing is a multimedia tutorial on DVD covering 920 woody plants with over 23,000 color photographs of leaves (summer and fall), flowers, fruits, twigs, bark and form for each plant. The software displays multiple images of all plant parts so user can develop a "feel" for normal field variation. A customizable self-quizzing section allows users to evaluate their progress in plant identification.

We recommend you install Virginia Tech Tree Identification using a fast WIFI connection. A cellular connection will generally be too slow. Text and photography by John R. Seiler, John A.

Using the Echo Meter Touch 2 Pro plug-in module, this app allows you to listen to record and automatically identify bats by their ultrasonic echolocation calls. The module and this companion app reveal the silent and often times invisible world of bats, providing outdoor enthusiasts, citizen scientists, and researchers an affordable and informative way to interact with these important creatures. There are two models: Echo Meter Touch 2 (EMT 2) is intended for nature enthusiasts and batting hobbyists and Echo Meter Touch 2 Pro is designed for bat professionals and features a higher quality microphone, adjustable gain, and higher sample rate. The Echo Meter Touch Ultrasonic Module senses ultrasonic signals, digitizes the signal, and transmits the ultrasonic data to the app on your iOS device. LISTEN TO BAT’S ECHOLOCATIONS EMT2 translates bat echolocations into frequencies that are audible to humans using two technologies. Wildlife Acoustics’ patented Real Time Expansion (RTE) allows you to listen to bats in real time with unparalleled fidelity. RTE maintains the timing and tonality of the original echolocations. Heterodyne (HET) listening via manual and automatic tuning is also available, for those accustomed to that way of hearing bats. VIEW THE ECHOLOCATIONS ON A SPECTROGRAM A real-time spectrogram shows the frequencies and timing of the echolocations. Scroll back in time and zoom in on previous "bat passes." SEE MOST LIKELY BAT SPECIES IN REAL-TIME*** The Auto ID feature analyzes the echolocation calls and suggests the two most likely bat species matches in real time. This is the same technology used in our professional Kaleidoscope Pro Bat Auto Identification software. Currently, the app can identify 26 species in North America, 25 in Europe and 57 in the neotropics. For more information on Kaleidoscope and a full list of species, visit our website. RECORD .WAV FILES Activate triggered recording mode to automatically save bat passes to full spectrum .wav files for analysis on a computer or to view on your iDevice. Or use manual record mode to control start and stop of recording. View the recording spectrogram and add voice or text notes. Listen to the recording using RTE, HET, or traditional Time Expansion Playback (playback at fractional speed to make the ultrasound audible). SEE YOUR PATH AND RECORDING LOCATIONS View in satellite or road map view. View identified species codes directly on the map. Go to the recording's spectrogram from the map view. Transfer to your computer to view in Google Earth. Your iDevice must have GPS capability or you must use a Bluetooth GPS receiver for this functionality. *Continued use of GPS running in the background can dramatically decrease battery life.* TRANSFER RECORDINGS TO YOUR COMPUTER The EMT 2 can transfer the .wav recordings to your computer over a Wi-Fi network or using a USB cable. SHARE RECORDINGS VIA EMAIL OR MMS MESSAGING And import and open files that have been shared with you. ***Because bats vary their echolocation calls in response to a wide variety of needs, no automated identification can achieve 100% accuracy in species identification. Auto-ID, though largely accurate, should not be relied on as a basis for scientific research. Auto-ID is intended for use in analyzing recordings of single bats in free flight in low clutter environments. Auto-ID will not work well on recordings of roost emergence, multiple or captive bats, bats in high clutter environments, or bat social calls. Auto-ID does not include every possible bat for each of the covered regions. Echo Meter is a registered trademark of Wildlife Acoustics, Inc.
