In the Northern Hemisphere, the winter season is well underway. Cold temperatures mean that species of all kinds must face many new challenges in order to survive the next few months. Spiders are no exception. One might assume that spiders die off once winter hits. While this is true for some species, it is not true for all spiders – many remain active in winter months. How do they manage this? Through a variety of physiological and behavioral adaptations. Behavioral adaptations include moving their homes to “overwintering sites” such as the “subnivean zone,” an area between the snow and the ground, or concealed locations in leaf litter or under bark, where it’s warmer. Spiders also have a physiological adaptation that helps them brave the cold months.

The Council on Library and Information Resources (CLIR) has selected the “Biodiversity Heritage Library Field Notes Project” for a 2015 Digitizing Hidden Special Collections and Archives award. The award of $491,713 will help support increased accessibility to original scientific documentation found in archival field notes in participating institution collections. Field notes provide valuable, primary research data about species and ecosystems that is often unpublished or unavailable through other sources.

Over the years, we’ve discovered that social media is a pretty awesome way to learn more about our collections. Recently, a Twitter conversation helped us unravel the true identity of an incredible natural history artist. In November, one of our star citizen scientists Siobhan Leachman was working on adding artist machine tags to images in the BHL Flickr (want to learn more about how to do that? See this guide!). She was working on Wonders of the Bird World (1921), which was digitized for BHL by Cornell University Library. The title page stated that it was illustrated by A.T. Elwes.

We are pleased to announce that the Fiscal Year 2015 BHL Annual Report is now available!

Want to learn how our collections grew this past year, or how our audiences engaged with these collections, or explore the many new and exciting citizen science and outreach initiatives we’ve embarked on this year?

Charles Darwin is famous for the theory of evolution by means of natural selection. The theory hinges on the mutability of species, whereby the propagation of certain favorable traits within members of a species may gradually result in the evolution of that species. The question of when Darwin first came to believe in the mutability of species – when he became a “convinced transmutationist” – has long been a point of contention among historians of science. There are two prevailing theories on the topic. The early conversion hypothesis states that Darwin developed a belief in the transmutation of species while on the Beagle voyage based on observed similarities between the fossils he was collecting and extant species in the area.
