Bees Of Maine, With A State Species Checklist, Alison C. Dibble, Francis A. Drummond, Constance Stubbs, Michael Veit, John S. Ascher
Biology and Ecology Faculty Scholarship
We present a new county checklist developed from bee research in Maine since the 1800s. The list contains 278 bee species in 37 genera and 6 families, of which all but 8 are native, with ≥50 taxa each in Andrena and Lasioglossum. Data for 16 counties from publications, museum collections, and recent surveys varied in number of species from 8 (Androscoggin) to 197 (Hancock). Research since 1930 on Vaccinium angustifolium (Lowbush Blueberry) led to many records. Twenty-one species are considered unusual, including 3 first recorded in 2016: Epeoloides pilosulus, Melitta melittoides, and Holcopasites calliopsidis. Maine records …
A Comparison Of Benthic Macroinvertebrate Assemblages Between Perennial And Intermittent Headwater Streams Of The Mattole River In Northern California, Usa, Mason S. London
Cal Poly Humboldt theses and projects
Intermittent streams are common throughout the world and comprise 60% or more of total river lengths in the conterminous United States. Despite their prevalence, intermittent streams are understudied, particularly first-order headwater streams, which are vital for maintaining the function, health and biotic diversity of river networks. In June 2016, I sampled five intermittent and five perennial headwater streams in the Mattole River watershed in northwestern coastal California, USA, to compare benthic macroinvertebrate (BMI) assemblages between intermittent and perennial streams. BMI samples were collected using a 500µm mesh D-net at eight randomly located riffles along a 150-m reach, and then composited, …
