Nous sommes heureux d’accueillir Federico Riva, PhD pour un stage post-doctoral. Au cours des prochains mois, il étudiera la répartition des papillons de jour d’Amérique du Nord et les tendances de leurs populations dans le but d’améliorer les méthodes de suivi. Nous lui avons demandé de nous parler de son parcours et de son expérience avec les papillons. Bienvenue dans l’équipe de eButterfly, Dr Riva!
Après des mois de travail, une version corrigée et améliorée de la taxonomie utilisée dans la base de données de eButterfly est désormais en ligne. Cette mise à jour améliorera le partage d’observations et l’exploration des données par les utilisateurs.
Le décompte annuel du 4 juillet est à nos portes! Chaque année, des centaines d’adeptes de l’observation des papillons participent à un effort conjoint pour compter les papillons dans des parcelles pré-établies de 12 km de rayon. La plupart des relevés sont réalisés par plusieurs personnes réparties à l’intérieur de chaque parcelles qui combinent leur résultats pour obtenir un décompte total d’espèces. Ces données sont ensuite utilisées pour des comparaisons entre les années. Ces suivis à long-terme permettent de détecter des changements dans les populations de papillons sur de grandes échelles. Vos listes d’observations sont aussi importantes pour eButterfly!
(English) Our new eButterfly Projects tool allows you to easily and quickly create a hub for your event, club, class, or organization. An eButterfly Project creates a space for you that pools observations of eButterfly users together. You can automatically include all of the checklists and observations that fit the places, taxa, users, or dates that you specify. Whether you’re starting a community science effort, creating a home for your user group, or running a butterfly bioblitz; eButterfly Projects is the new tool for you.
(English) Every time butterfly watchers raise binoculars and cameras to record a butterfly sighting, they collect important data. Recording the number, date, and location of each and every butterfly, no matter how common or rare, may seem trivial, even repetitive— but this detailed information can be invaluable to science and conservation. Join Rodrigo Solis Sosa, our Human Network and Data Coordinator, as he explains how to use eButterfly in this recorded webinar from April 27.
Forecasting species responses to climate change is integral to the development of adaptive and practical conservation decisions. Butterflies are climate-constrained in at least two ways, as ectotherms, the climate has a defining role in dictating where butterflies can live. Additionally, a warming climate may have huge impacts on their host plant availability. These constraints could mean certain butterfly species may have to move north, or up in elevation, to stay within their preferred temperature range. Predicting how butterflies might respond to such temperature and host plant shifts could inform decisions involving conservation prioritization, species management, and natural resource management.
(English) We’re excited to announce some great improvements and new tools for eButterfly that we just released, with even more on the way. Our team has worked hard all winter to improve how the communications center operates, adding additional languages, upgrading the checklist submission process, improving the user experience for viewing checklists, updates that increase the performance of eButterfly, and many minor bug fixes.
(English) In 2010 when the largest butterfly in North America fluttered among Ardys Fisher’s flowers at the end of July, she knew it was something neat. Now, our study published in Frontiers in Ecology and Evolution this week shows an unusually rapid northward range shift by the Eastern Giant Swallowtail over the last two decades.
(English) Western butterfly populations are declining at an estimated rate of 1.6% per year, according to a new report published this week in Science. The report looks at more than 450 butterfly species, including the western monarch, whose latest population count revealed a 99.9% decline since the 1980s.
(English) From the first observation of 2020, a Gulf Fritillary nectaring on the Gulf coast of Florida submitted by Gary Leavens, to a Long-tailed Skipper nectaring at the end of December shared by mbspang, butterfly watchers added over 38,500 butterfly records to the ever growing eButterfly database of checklists. The reports fluttered in all summer long. We had more than 8,300 checklists with over 22,000 photographs comprising 523 species of butterflies reported during the year.
