Decreased Cortisol Among Hikers Who Preferentially Visit And Value Biodiverse Riparian Zones, Ellie Opdahl, Kathryn Demps, Julie A. Heath
Decreased Cortisol Among Hikers Who Preferentially Visit And Value Biodiverse Riparian Zones, Ellie Opdahl, Kathryn Demps, Julie A. Heath

While outdoor recreationists often report increases to their well-being for time spent in nature, the mechanisms through which local ecologies affect human health have been difficult to quantify, and thus to manage. We combine data from pre-post salivary cortisol measures, GPS tracks, visitor photos, and surveys from 88 hikers traversing several types of landscape within peri-urban public lands in southwest Idaho, USA. We find that time in biodiverse riparian areas and areas of perceived aesthetic value correlates with decreases in salivary cortisol and improved well-being for hikers. Wildlife sightings were not associated with changes in salivary cortisol, but were associated …

Over the last century, Pacific herring, a forage fish of tremendous cultural, economic, and ecological importance, has declined in abundance over much of its range. We synthesize archaeological fisheries data spanning the past 10,000 y from Puget Sound in Washington to southeast Alaska to extend the ecological baseline for herring and contextualize the dynamics of modern industrial fisheries. While modern herring populations can be erratic and exhibit catastrophic declines, the archaeological record indicates a pattern of consistent abundance, providing an example of long-term sustainability and resilience in a fishery known for its modern variability. The most parsimonious explanation for the …
Towards The Identification Of Lampreys (Lampetra Spp.) In Archaeological Contexts, Ross E. Smith, Virginia L. Butler
Towards The Identification Of Lampreys (Lampetra Spp.) In Archaeological Contexts, Ross E. Smith, Virginia L. Butler

Lampreys were and continue to be an important resource for Native Americans in the Pacific Northwest. Lampreys possess several skeletal structures that are regularly identified in marine mammal and bird stomach contents and fecal samples, suggesting that lamprey elements may preserve in archaeological contexts. However, their remains have not been identified in archaeological faunal samples in the Pacific Northwest. This may be due to the lack of an adequate "search image" for lamprey remains among faunal analysts and limited use of line screen sampling. Descriptions and photographs of lamprey remains that are most likely to survive in archaeological contexts are …

Here we present information on the conservation status of ruffed lemurs (Varecia) north of the Bay of Antongil in northeastern Madagascar. Two contiguous protected areas were recently established that traverse this region via blocks of forest connected by narrow forest corridors: the Masoala National Park, which expands further to the east, and the Makira Protected Area, which expands further to the west and northwest. The two extant ruffed lemurs, Varecia variegata and V. rubra, overlapped in this region historically and, on rare occasions, hybridized. As such, land north of the Bay of Antongil is a critical part …
