A New Species

Montezuma Well is a geothermal limnocrene spring within Montezuma Castle National Monument, Yavapai County, Arizona, U.S.A. The Well’s unusual geological qualities, water chemistry, and a history of aquatic plant collecting are discussed. Evidence to support the fact that a unique species of Potamogeton has likely grown in this location for thousands of years and is now recognized as the seventh apparent autochthonous endemic species from this small area is presented. Although this new species shares a few superficial characters with P. illinoensis Morong, it is easily distinguished by its massive height (7–8 m tall), lack of floating leaves, long acuminate leaf apices of its submerged leaves, and bright translucent green leaf color. A complete description with drawing and photographs is provided.

Roberto Massimo Lawley (1818–1881) was a non-academic naturalist who made a major contribution to the Tuscan scientific community of his time. He was involved in the foundation of two societies (Società Italiana di Malacologia, 1874–1899; Società Toscana di Scienze Naturali, 1874–today) and a publishing house (Biblioteca Malacologica Italiana). He first devoted himself to malacology, but Neogene fossil fishes became his main interest. Over the years, he gathered a huge private collection of fossils and produced 18 scientific papers, dealing mainly with fossil sharks. Subsequent revisers criticized his approach to fossil taxa: their observations were generally sound, but they failed to fully recognize Lawley's scientific merits. His scientific papers, new taxa established by him and eponymys are given in the Appendix.

Natural Resource Managers

Natural resource managers need up-to-date information about how people interact with public lands and the meanings these places hold for use in planning and decision-making. This case study explains the use of public participatory Geographic Information System (GIS) to generate and analyze spatial patterns of the uses and values people hold for the Browns Canyon National Monument in Colorado. Participants drew on maps and answered questions at both live community meetings and online sessions to develop a series of maps showing detailed responses to different types of resource uses and landscape values. Results can be disaggregated by interaction types, different meaningful values, respondent characteristics, seasonality, or frequency of visit. The study was a test for the Bureau of Land Management and US Forest Service, who jointly manage the monument as they prepare their land management plan. If the information generated is as helpful throughout the entire planning process as initial responses seem, this protocol could become a component of the Bureau’s planning tool kit.
