Postglacial fire and vegetation histories of a mid-elevation mixed-conifer forest in the Gallatin Range, MT, USA
A 13,500-year-old record from Langohr Wetland in the Gallatin Range of southwestern Montana offers new insights into the vegetation and fire history at middle elevations within the Greater Yellowstone Ecosystem. Pollen data suggest that following deglaciation, a tundra–steppe established until warmer and wetter conditions than before could support Picea parkland. The development of an open, predominantly Pinus mixed-conifer forest from ca. 9300–7…
Patagonia's Late Holocene lake sediments reveal no major black carbon sources for Antarctica
Past and present biomass consumption by herbivores and fire across productivity gradients in North America
Herbivores and fire are important consumers of plant biomass that influence vegetation structure, nutrient cycling, and biodiversity globally. Departures from historic biomass consumption patterns due to wild herbivore losses, livestock proliferation, and altered fire regimes can have critical ecological consequences. We set out to (i) understand how consumer dominance and prevalence responded to spatial and temporal moisture gradients in Holocen…
Organic layers preserved in ice patches
Growing season temperatures play a crucial role in controlling treeline elevation at regional to global scales. However, understanding of treeline dynamics in response to long-term changes in temperature is limited. In this study, we analyze pollen, plant macrofossils, and charcoal preserved in organic layers within a 10,400-year-old ice patch and in sediment from a 6000-year-old wetland located above present-day treeline in the Beartooth Mountai…
Insights into the indigenous-managed landscape in southeast Australia during the Holocene
Understanding the long-term interactions between people and the ecosystem in which they live is vital for informing present-day ecosystem management plans. The use of pollen data for palaeoecological reconstructions is often limited by the low taxonomic resolution of pollen, which often reduces the detail of reconstructions of human influence on past vegetation. This is true for Australia where Myrtaceae, particularly Eucalyptus species, dominate…
An Application of Ground-Penetrating Radar at a Greater Yellowstone Area Ice Patch
Ice patches are an irreplaceable archive of past events. With atypical melting now occurring around the world, it is important to be able to quantify and interpret the potential of what remains in areas of archaeological interest. A ground-penetrating radar (GPR) survey was conducted at an archaeologically productive ice patch in the Greater Yellowstone Area to identify sediment layers in which archaeological materials may be present. Numerous re…

Drivelines, hunting blinds, effigies and intercept hunting strategies in the Greater Yellowstone Ecosystem, USA
This paper shares a description of cairn lines and hunting blinds in association with an ice patch in the Greater Yellowstone Ecosystem. Until now no definitive stone features, including drivelines and hunting blinds, have been reported in association with Greater Yellowstone Ecosystem ice patches; however, such features are known from ice patches in northern North America, eg Yukon Territory. In the system reported here, the ice patch is presume…
Rethinking resilience to wildfire
Record-breaking fire seasons are becoming increasingly common worldwide, and large wildfires are having extraordinary impacts on people and property, despite years of investments to support social–ecological resilience to wildfires. This has prompted new calls for land management and policy reforms as current land and fire management approaches have been unable to effectively respond to the rapid changes in climate and development patterns that s…
Millennial scale climate-fire-vegetation interactions in a mid-elevation mixed coniferous forest, Mission Range, northwestern Montana, USA
Mixed coniferous forests are widespread at middle elevations in the Northern Rocky Mountains, yet relatively little is known about their long-term vegetation and fire history. Pollen and charcoal records from Twin Lakes, in the Mission Range of northwestern Montana provide information on mixed-coniferous forest development and fire activity over the last 15,000 years. These data suggest an open parkland and minimal fire activity before 13,500 cal…
