Using the remotely operated vehicle Deep Discoverer, we observed a large stylodactylid shrimp resting on a sedimented sea floor at 4826 m in the Marianas Trench Marine National Monument. The shrimp was not collected but most closely resembled Bathystylodactylus bathyalis, known previously only from a single broken specimen. Video footage shows the shrimp facing into the current and extending it...

DURING 8 DAYS in early August and October, 1968, the members of an expedition from the University of Hawaii examined the distribution and abundance of sea urchins in two bays along the Kona (leeward) Coast of the Island of Hawaii (Fig. 1) : Kealakekua Bay (19 0 28' N; 155 0 55' W) and Honaunau Bay (19 0 25' N ; 155 0 55' W). The major sampling effort was expended in Kealakekua, the larger of th...

A week ago I was standing with my wife by the River Tagus in Lisbon, next to the Monument to the Discoveries. The monument is at the spot where Vasco da Gama set out to discover the southeast passage from Europe to Asia, past the Cape of Good Hope. Vasco’s discovery marked the beginning of the Portuguese maritime empire. At the furthest tip of Europe, Portugal was perfectly situated to found su...

Management of impacts to park resources and the quality of the visitor experience can be guided by the National Park Service Visitor Experience and Resource Protection (VERP) framework. This article describes a program of research to support application of this management framework to the soundscape of Muir Woods National Monument, California. Initial visitor surveys identified visitor-caused n...

Most current conservation literature focuses on the preservation of hotspots of species diversity and endemism, as if the two were geographically synonymous. At landscape scales this may not be the case. We collected data from 367 1000-m2 plots in the Grand Staircase–Escalante National Monument, Utah, USA, to show that: (1) the vast majority of plant species are locally rare; (2) species-rich a...

Research has found that human-caused noise can detract from the quality of the visitor experience in national parks and related areas. Moreover, impacts to the visitor experience can be managed by formulating indicators and standards of quality as suggested in park and outdoor recreation management frameworks, such as Visitor Experience and Resource Protection (VERP), as developed by the U.S. N...

Heavy metal escapement associated with ore trucks is known to occur along the DeLong Mountain Regional Transportation System (DMTS) haul road corridor in Cape Krusenstern National Monument, northwest Alaska. Heavy metal concentrations in Hylocomium splendens moss (n = 226) were used in geostatistical models to predict the extent and pattern of atmospheric deposition of Cd and Pb on Monument lan...
