As in the previous study, records and descriptions of specimens from outside Nebraska before the writer are included where these seem to add anything to our knowledge of the species concerned.

Southwestern Rare and Endangered Plants
Preliminary Report on the Reproductive Biology of the Threatened Chisos Mountain Hedgehog Cactus BONNIE B. AMOS and CHRISTOS VASSILIOU Angelo State University, Texas Abstract: The Chisos Mountain hedgehog cactus (Echinocereus chisoensis, Cactaceae) is a narrow endemic restricted to an approximately 100 square mile area in Big Bend National Park, Texas. It was listed as threatened in 1987 as Echinocereus chisoensis var. chisoensis. An investigation of the reproductive biology and pollination ecology conducted in 1999 and 2000 revealed the taxon to be homogamous, self-incompatible, xenogamous, and heavily dependent upon the cactus oligolectic bee, Diadasia rinconis (Anthophoridae) for pollination. Despite infrequent bee visitation, fruit set from open pollination is high and fruits produce large numbers of seeds. Predation in 2002, probably from rodents as a result of severe drought conditions, was severe on plants, flower buds, and fruits. The Chisos Mountain hedgehog cactus, or Chisos jillo (Opuntia leptocaulis DC.), ocotillo (Fouquieria pitaya (Echinocereus chisoensis W. Marshall), is 1 of splendens K.

Components of Nest Provisioning Behavior in Solitary Bees (Hymenoptera: Apoidea)*

Neff Central Texas Melittological Institute, 7307 Running Rope, Austin, Texas 78731, USA Received 13 June 2007 – Revised 28 September 2007 – Accepted 1 October 2007 Abstract – The components of nest provisioning behavior (resources per cell, transport capacity, trip dura- tion, trips per cell) are examined for a data set derived from the literature and various unpublished studies. While there is a trade-off between transport capacity and trips required per cell, the highest provisioning rates are achieved by bees carrying very large pollen loads at intermediate trip durations. Most solitary bees appear to be either egg or resource limited, so sustained provisioning rates over one cell per day are unusual.

We thank all of you. The bulk of the text was compiled by Sam Droege at the USGS Native Bee Inventory and Monitoring Lab over several years from 2004-2008. We regularly update the manual with new information, so, if you have a new technique, some additional ideas for sections, corrections or additions, we would like to hear from you. Please email those to Sam Droege ([email protected]). You can also email Sam if you are interested in joining the group’s discussion group on bee monitoring and identification.

Bees in drylands are particularly abundant and diverse, with potential for large compositional diferences and seasonal turnover across ecotones. To better understand how future ecosystem state transitions may infuence bees, we compared bee assemblages and their seasonality among sites at the Sevilleta National Wildlife Refuge (NM, USA) that represent three dryland ecosystem types (and two ecotones) of the southwestern U.S. -
Floral Guilds of Bees in Sagebrush Steppe: Comparing Bee Usage Of
ABSTRACT: Healthy plant communities of the American sagebrush steppe consist of mostly wind-polli- • nated shrubs and grasses interspersed with a diverse mix of mostly spring-blooming, herbaceous perennial wildflowers. Native, nonsocial bees are their common floral visitors, but their floral associations and abundances are poorly known. Extrapolating from the few available pollination studies, bees are the primary pollinators needed for seed production. Bees, therefore, will underpin the success of ambitious seeding efforts to restore native forbs to impoverished sagebrush steppe communities following vast Floral Guilds of wildfires. This study quantitatively characterized the floral guilds of 17 prevalent wildflower species of the Great Basin that are, or could be, available for restoration seed mixes. More than 3800 bees repre- senting >170 species were sampled from >35,000 plants. Species of Osmia, Andrena, Bombus, Eucera, Bees in Sagebrush Halictus, and Lasioglossum bees prevailed. The most thoroughly collected floral guilds, at Balsamorhiza sagittata and Astragalus filipes, comprised 76 and 85 native bee species, respectively. Pollen-specialists Steppe: Comparing dominated guilds at Lomatium dissectum, Penstemon speciosus, and several congenerics. In contrast, the two native wildflowers used most often in sagebrush steppe seeding mixes—Achillea millefolium and Linum lewisii—attracted the fewest bees, most of them unimportant in the other floral guilds.
