California academy of sciences diatom collection

31 Juillet 2014,

Publié par Bioecologie

The CAS Diatom Collection Web Site is an ongoing project to present taxonomic information, images, records of collections, and references pertaining to diatoms. This work has been supported in part by grants BSR-9017609 and DEB-9505269 from the National Science Foundation.

Types Catalogue provides information on types in the CAS collection.

Hanna Database provides information on the Specimen, Samples, and Publication tables. The Specimen table contains 75,000 records of specimens that have been identified on slides. The Sample table contains detailed information on 29,000 samples accessioned in the Diatom Collection. The Publication table contains 12,000 bibliographic references.

Diatom identification resources
Currently, the project focuses on recent freshwater diatoms of the United States. In the future, it will include marine and fossil taxa with an expanded geographic range.

Introduction to Diatoms


Freshwater Diatom Identification and Information Resource includes images, keys, and a variety of collection, literature and distribution information to facilitate our understanding of freshwater diatom biodiversity, systematics, and evolution.

Catalogue of diatoms names 
The Catalogue of Diatom Names is a compilation of names of diatom genera, species and taxa at infraspecific ranks (64,000 names). It has been assembled during the past 12 years by staff at the California Academy of Sciences. It includes all scientific names of diatom genera, species, and taxa at infraspecific ranks, with authorship, date, place of publication, page of description, basionym or replaced name (if applicable), status (valid or invalid), and occasionally type information.

The lizard lab: "We investigate the behaviour, ecology and evolution of lizards. In addition to lizards, we are currently working on tree frogs and cane toads and have previously worked on snakes, mole-rats and Malawi cichlids. We are part of the Department of Biological Sciences, within the Division of Brain, Behaviour and Evolution at Macquarie University. Take a look at our research to find out the specific details of what we do."

Virtual Issue: Ecological Statistics are Methods too

Methods in Ecology and Evolution has been publishing papers on statistical ecology since its inception in 2010. Since the last International Statistical Ecology Conference (ISEC) meeting, we have published many more papers, of an increasing quality and influence. This Virtual Issue brings together some of those papers - but also misses out many more that will be just as interesting.

The papers chosen show the range of statistical issues that have been covered in MEE: movement ecology, distributions, abundance, dynamics, capture/recapture, as well as papers on how we should interpret our results. MEE also publishes applications, which outline recent developments in implementations of methods, for example new software and packages, and a couple of these are included in this Virtual Issue.

Le blaireau européen

20 Juillet 2014,

Publié par Bioécologie

Le Muséum Nationale d'Histoire Naturelle (France) vous emmène à la rencontre du Blaireau européen, véritable pelleteuse naturelle !

Le blaireau est un vrai bâtisseur. Il déplace des tonnes de terre et peut creuser des terriers composés de très nombreuses galeries pouvant aller jusqu’à plus d’une trentaine pour les plus anciens, pour y loger toute sa descendance...
Certains de ces terriers enfouis de trois à quatre mètres de profondeur sont occupés pendant des dizaines d’années par de nombreuses générations de Blaireaux. Omnivore, le blaireau se nourrit d’à peu près tout ce qui lui tombe sous la patte : insectes, lombrics, rongeurs, racines, champignons…
Cousin de la fouine et de la belette, le Blaireau européen est cependant beaucoup plus gros puisqu’il mesure jusqu’à 70 cm de long et peut peser jusqu’à une vingtaine de kilos.
C’est la nuit qu’il vit et sort se nourrir. Mais c’est aussi là qu’il trouve la mort sur les routes, quand il n’a pas été délogé et chassé par les hommes qui ne le supportent pas.
