iBatsID: an online tool for the identification cries of European bats

Wednesday 8 August 2012

A new identification software, by automatic classification of ultrasonic bat just to see the day. Its use is similar to what is currently common in this area. The major new features are free and its method of use (Java platform hosted online on the internet) impressive and its area of ​​use (Europe). The user enters values ​​for different acoustic parameters (former. duration of cries, peak frequency, terminal frequency, etc.) and software iBatsID returns the probability of each cry of belonging to different species. The identification to this level is therefore fully quantitative (probabilistic). The probabilistic interpretation of the results is then left to the user. Measurements of acoustic parameters can be performed under different software although the measures are optimized as paid software Sonobat.

By the use of sound content in a very wide variety (on the plans as inter and intra-specific sources of their geographical), the ability to compare information on populations of bats sampled acoustically is now possible at the European level. Two main limitations are discussed, less accurate vis-à-vis other methods reach more local (but with fewer species included) and low reliability of identification Myotis at specific (recurring problem for all methods available to date).

Training to the capture of bats

Thursday 31 May 2012

Despite the opportunities offered by the identification of animals within their lodges and advances in acoustic detection, capture still essential, especially for evaluation of reproductive status, the identification of certain species, followed by the radio-or the collection of biological samples. The capture is not trivial in terms of risk to bats and because of the increase of nominations, it seemed essential to establish a training system to capture the benefit of bats and bat.

So, sheets 13 and 19 the National Action Plan (PNA) Bats have been drafted to address this lack :

  • Fiche action 13 : Development and validation of protocols national survey and monitoring of bat populations.
  • Fiche action 19 : Establish a national training system for monitoring and studying the bats, especially for the procedure for issuing authorizations capture.

The design and implementation of these actions are performed by working groups and coordinated by the MNHN (National Museum of Natural History, Paris). The group consists of experienced bat inspired by what already exists in the regional groups and the NFB. Beyond the Plan, these missions are designed to establish sustainable systems that will define a scientific framework to capture in order to best ensure the safety of animals and quality of data collected.

Writing a capture guide and a technical manual to help identifying and taking action (in progress, action 13 of PNA), and implementation of training (actionactionwill synthesize and disseminate knowledge to the practice of capturing in a scientific. This will, other, homogenize the action and the nature of the data, so they are fair and comparable to the other chiroptérologue.

The formation evening nominative, that is to say the same for all persons who wish to develop additional skills to conduct catch autonomy, whether professional or volunteer naturalists. In order not to promote the capture technique as the first approach to discipline, should be to ensure that students have prior knowledge of general biology and ecology of bats and the various monitoring techniques and inventory.

During this training, students will be coached by trainers (experienced bat who volunteered) who complete, first, a national course in order to standardize training and to have joint discussions on ethics, priorities and approach.

For training the trainee will have access to :

  • a code of ethics and a note of commitment-a-vis health risks that must be read and signed by the trainee;
  • ongoing training in the field, through the use of a book containing all the training objectives, to validation by a designated trainer. The field training will be done during capture sessions set up for scientific and / or conservation;
  • a theoretical course in region (or inter-regions according to the application, 2 days, free) according to a national repository which aims to present the context in which science must be a catch, Ethics, regulations, health aspects and the theoretical and technical knowledge.

To ensure that trainees are able to capture an independently after training (book validated and probation completed), should assess their skills as a common repository for consistency and fairness in assessment courses in region (or inter-regional).

To date, the nominations for the capture of bats are addressed to DREAL, MEDDTL transmitted to and signed by the advice of Prefectures CNPN. By region, regional coordinators, groups or the bat CSRPN are available to have an opinion on the application. It was agreed with the MEDDTL CNPN and once the training establishment, authorization to capture issued at the end of the training will be required in addition CERFA 13616*01 "Derogation for the capture or removal, the destruction, deliberate disturbance of specimens of protected species "to any request for exemption. For the time being, the working group decided to focus on training. Any alterations to the processing of exceptions is a complex subject that will be addressed at a later stage in consultation with all stakeholders.

The first step in this process is to identify the trainers. A paper on the role and responsibilities of the trainer was prepared (download here). If you want to take part in this project by becoming a trainer, do you know by completing the form (download here) and return it to your local bat group (Regional Coordinator SFEPM), the MNHN (jmarmet@mnhn.fr) or SFEPM (chiro.sfepm@orange.fr) before 12 June 2012. Once the trainers identified, they will meet in the fall to attend a training course cross.

When all forms have been received and centralized, the working group "to capture training" will make an appointment in close consultation with regional groups and bat DREAL, to agree on a list on its own merits, depending on experience and motivation of bat.

Finally, Book training will be distributed this spring, to all other network, so that everyone can find out. However, validation of targets and the first theoretical courses can only be done once the trainers trained, they will therefore be in 2013.

For more information, Questions or comments concerning the formation, you can contact us by email : jmarmet (at sign) mnhn.fr or telephone : 01 40 79 57 64.

Bat, Tags bright and flight direction

Monday 2 April 2012

Were you familiar with the use of tags for light to track bats ?
Older models have helped to track animals and record their acoustic emissions.

A new generation of light tags is now under review, them in the air leaving a luminous trail
for a few moments. The material is still in development but here are exclusively the flight path of a common Pipistrelle (Pipistrellus pipistrellus), equipped and monitored near Lake Constance in Germany. A pathway for the most atypical !
Future trials will learn about strategies for the use of space bats.

National meetings to bat Natural History Museum of Bourges, 2012

Saturday 10 March 2012

Ce week-end du 2-3-4 March took place the national meetings of the bats SFEPM in Bourges.
Over 350 people (amateur or professional) goshawks were left to study presentations, roundtables and technical workshops to share and keep abreast of the news of Chiroptera. These meetings are a time bisanuelles must for anyone intéresssant to bat, so much so that even our neighboring French-speaking Belgians or Swiss movement.

The site of the Museum of Bourges provides the list of participants and the program of these 3 days of meetings.

A big thank you to the organizing team and participants, growing number !

The just released his vespere second issue !

The vespere is an electronic journal devoted to the naturalist bats, open access. Its mission is to disseminate information quickly and easily that naturalists do not accept the scientific literature. The vespere however, retains a presentation in line with scientific standards and publishes the results of one-time inventory, targeted studies (former. account rendered radio-tracking) or reports of expeditions. For more information about the journal, visit the journal The vespere.

Happy reading,

News in January 2012

Saturday 7 January 2012

New year, new resolution, we will present a summary of the news of bats in the world on a monthly basis (instead of bi-weekly). Otherwise, because many older articles (from before the mid-twentieth century) have been forgotten, are inaccessible or have never really been known, We will also present some of these items we will endeavor to make available as a PDF.

Here is our selection for this new year in January :

- an article by 2011 which presents the results of radio-tracking performed on Miniopterus schreibersii in southern France in the LIFE program [download the PDF],

- an article by 2011 which uses data from echolocation to substantier presence data for species not confirmed in Ireland (Barba Stella barbaric barbastellus and Nyctalus noctula) and presents data on echolocation Nyctalus leisleri en Irlande [download the PDF],

- of a paper 2011 which is a synthesis of the communicative potential contained in the echolocation calls [link to the English abstract and PDF],

- two articles published in 1896 and 1897 by Rollinat & Trouessart in “Memoirs of the Zoological Society of France” on reproduction in bats and particularly in Myotis myotis (then known under the name of Vespertilio murinus Scribe) and Rhinolophidés (Rhinolophus ferrumequinum, R. hipposideros and R. euryale) [download article 1896 and that of 1897],
