New fossils help pinpoint when some birds started relying on a seed-based diet and reveal that disparate bill shapes evolved repeatedly throughout bird evolutionary history.
Cervical screening in low-resource settings remains an unmet need. Lectins are naturally occurring sugar-binding glycoproteins whose binding patterns change as cancer develops. Lectins discriminate between dysplasia and normal...
Squamous cell carcinoma and adenocarcinoma of the oesophagus are cancers that develop from distinct epithelial sub-types; however, they are both related to chronic inflammation of differing aetiologies. Inflammation leads to...
This four-page program details the Curtain Club of Ursinus College's production of Ring Around Elizabeth, held December 12, 1942 in Thompson-Gay Gymnasium. It includes information about the directors, cast, production of the...
The Bird that Flew Backwards examines women poets from literary Modernism in the 1910s and Beat culture in the 1950s. Analyzing these eras in tandem reveals contrasting historical constructions of American womanhood and how...

Marketing Professor Jane Thomas will receive the Kinard Award for teaching. English Professor John Bird will serve as the Thompson Scholar to help teach critical thinking.
Migration is a widespread response of birds to seasonally varying climates. As seasonality is particularly pronounced during interglacial periods, this raises the question of the significance of bird migration during past...
Called "The Purloining of Prince Oleomargarine," it is the story of a young boy who eats a flower sprouted by a magical seed and gains the ability to talk to animals. Bird said he spotted Twain's notes on the story while...

Conversion of forest to oil palm agriculture is a significant and ongoing threat to tropical biodiversity. Despite this, little is known about the value of riparian reserves in oil palm and how these conservation set‐asides...
Sex-specific mortality is frequent in animals although the causes of different male versus female mortalities remain poorly understood. Parasitism is ubiquitous in nature with widespread detrimental effects to hosts, making...
The systematics of Madagascar's extinct elephant birds remains controversial due to large gaps in the fossil record and poor biomolecular preservation of skeletal specimens. Here, a molecular analysis of 1000-year-old fossil...
These guidelines provide a practical and evidence-based resource for the management of patients with Barrett's oesophagus and related early neoplasia. The Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument...

Many bird species, especially song birds but also for instance some hummingbirds and parrots, have noted dialects. By this we mean that locally a particular song is sung by the majority of the birds, but that neighbouring...

When Elizabeth von Arnim's novel 'Introduction to Sally' appeared in 1926, the critical response was divided. Dame Ethel Smyth may have told von Arnim the book was her 'masterpiece' but some were less convinced; the reviewer in...
Scavenging and predatory wildlife can ingest lead (Pb) from lead-based ammunition and become poisoned when feeding on shot game animals. Humans can similarly be exposed to ammunition-derived lead when consuming wild-shot game...
AbstractPhilomela holds a privileged place in Euro-American poetry. Tracking the nightingales in Ovid, Marie de France, Gascoigne, Shakespeare, Milton, Coleridge, and Elizabeth...
Abstract: Roads and their traffic can affect wildlife over large areas and, in regions with dense road networks, may influence a high proportion of the ecological landscape. We assess the abundance of 75 bird species in relation...
Empirical evidence from many regions suggests that most species would be least negatively affected if human food demand were met through high-yield agricultural production and conservation of nonfarm ecosystems (land sparing)...
