Mcconnell's Flycatcher Mionectes Macconnelli Is More Than One Species
Steven L. Hilty & David Ascanio 270 Bull. B.O.C. 2014 134(4) McConnell’s Flycatcher Mionectes macconnelli is more than one species by Steven L. Hilty & David Ascanio Received 25 April 2014 Summary.—Information on voice, display behaviour, elevational distribution and morphology of McConnell’s Flycatcher Mionectes macconnelli indicate that the two northern populations, long regarded as a single species, actually comprise two species-level taxa—a widespread lowland form macconnelli and a highland form roraimae. The two forms are similar in plumage, but difer signifcantly in wing and tail length, and most importantly in vocalisations and display behaviour. They are separated by elevation, with macconnelli found in humid lowland forest up to c.500 m and roraimae usually well above 500 m. Another highland taxon, mercedesfosteri, difers litle from roraimae and is not recognised here as distinct, although its voice is unknown. Two isolated populations, one in central Peru, the other in lowland Amazonia are not evaluated, but merit additional study. During the past few decades a beter understanding of mechanisms underpinning reproductive isolation has sparked a re-examination of species limits of many taxa. Avian vocalisations and habitat preferences, in particular, have been shown to be important isolating mechanisms (Zimmer 1997, Isler et al. 1999, Zimmer & Whitaker 2000, Whitaker 2002, Salaman et al. 2003, Braun et al. 2005). This paper documents an example of two morphologically similar forms, Mionectes m. macconnelli and M. m. roraimae, which we believe have achieved reproductive isolation through voice, behaviour and diferences in elevational distribution. McConnell’s Flycatcher Mionectes macconnelli is a drab, mostly olive-plumaged Tyrannidae found east of the South American Andes. -

Why the World's Tallest Waterfall Is Named Angel Falls
terrae incognitae, Vol. 44 No. 1, April, 2012, 16–42 Why the World’s Tallest Waterfall is Named Angel Falls Karen Angel Eureka, California, USA Jimmie Angel (1899–1956) was an aviator and adventurer in the early years of air exploration. This article discusses his discovery of Angel Falls, the world’s tallest waterfall, which bears his name, and the impact of that discovery — and his reputation and dogged determination — on later expeditions into the Venezuelan interior. The author, Angel’s niece, pieces together this fascinating story using a blend of dedicated archival research and painstakingly acquired family history and the reminiscences of friends and acquaintances of Jimmie and his wife Marie. The result is a tale of modern-day exploration and geographic discovery. keywords Jimmie Angel, Angel Falls, Auyántepui, E. Thomas Gilliard, Anne Roe Simpson, George Gaylord Simpson, Venezuela When I began researching the life of American aviator James “Jimmie” Crawford Angel (1899–1956), there were many stories about him in books, newspapers, magazines, and more recently on websites and blogs. Some stories can be verified by the Angel family or other sources; some stories are plausible, but remain unverified; other stories are fabrications. The result is a tangle of true stories and unverified stories. Finding the truth about Jimmie Angel is also complicated because he himself repeated the various unverified stories that became legends about his life.1 As the daughter of Jimmie Angel’s youngest brother Clyde Marshall Angel (1917– 97), I had heard stories about my uncle since childhood, but the family had few documents to support the stories. -

This species inhabits rainforest on granitic substrate on the northwestern edge of the Guiana Shield (Estado Amazonas, Venezuela). The new species is distinguished from congeners by sexual dimorphism, its unique male color pattern (including two bright orange parotoid marks and two orange paracloacal spots on dark brown background), call characteristics and other morphological features. Though to the new species is known only from the northwestern edge of the Guiana Shield, its distribution may be more extensive, as there are no significant biogeographic barriers isolating the type locality from the granitic lowlands of Venezuela.

In total, 26 desmid taxa were found and identified as new records for the desmid flora of Turkey based on their morphotaxonomic characteristics and ecological preferences. The taxa identified belong to the genera Actinotaenium (1), Closterium (1), Cosmarium (15), Micrasterias (1), Spondylosium (1), Staurastrum (5), Teilingia (1), and Tetmemorus (1). Morphotaxonomy, ecology, and distribution of each species were discussed in detail. Key words: Desmids, new records, high mountain lakes, Artabel Lakes Nature Park, Turkey 1.
