Diverse elevational diversity gradients in Great Smoky Mountains National Park, U.S.A.: Chapter 10

Why does the number of species vary geographically? The earliest naturalists puzzled over this question, as do many biogeographers and macroecologists today. Over the last 200-plus years, the most striking geographic pattern in species richness – the decline in species richness with increasing latitude – has received the most attention. Thanks to many recent theoretical developments, coupled with global-scale databases and satellite technology, the number of candidate mechanisms that shape the latitudinal diversity gradient has been whittled down to a manageable number.

A review of the genus Agapetus Curtis (Trichoptera: Glossosomatidae) in eastern and central North America, with description of 12 new species

Twenty-nine species of caddisflies in the genus Agapetus Curtis in eastern and central North America are reviewed. Twelve are described as new species: Agapetus aphallus (known only from females); Agapetus baueri , Agapetus flinti , Agapetus harrisi , Agapetus hesperus , Agapetus ibis , Agapetus kirchneri , Agapetus meridionalis , Agapetus pegram , Agapetus ruiteri , A gapetus stylifer , and Agapetus tricornutus . Agapetus rossi Denning 1941 is recognized as a junior subjective synonym of Agapetus walkeri (Betten and Mosely 1940), new synonym. A key to males is provided, and species’ distributions are mapped.

The crane flies (Diptera: Tipuloidea) of Great Smoky Mountains National Park

The list of crane flies (Diptera: Ptychopteridae, Tipuloidea, Trichoceridae) known from Great Smoky Mountains National Park is updated. Sampling in association with the All Taxa Biodiversity Inventory of Great Smoky Mountains National Park resulted in the addition of 107 new Park records, bringing the current list to 250 species. This species assemblage is much richer than those of surrounding areas, although similar in composition. Total richness is estimated to be between 450 and 500 species for Great Smoky Mountains National Park.
