Abstract Aims Some biogeographical regions act primarily as donors of colonists to other regions, while others predominantly recipient areas. How some biotas become dominant do not is a largely historical question that has received surprisingly little attention from biogeographers. Here, we seek answer this for the cold‐water North Pacific biota, which did exist forty million years ago but now principal donor biota outside tropics. Location We focus on cool‐temperate coastal Ocean over last...
Abstract. Examination of climatic and oceanographic changes through the Holocene (11.75 ka–present) allows for an improved understanding contextualization modern climate change. Climate records can be utilized as a “baseline” from which to compare also provide insights into how environments experience recover However, individual studies on in literature tend focus distinct geographic location, specific proxy record, or certain aspect (e.g., upwelling precipitation), resulting localized,...
Understanding past coastal variability is valuable for contextualizing modern changes in settings, yet existing Holocene paleoceanographic records the North American Pacific Coast commonly originate from offshore marine sediments and may not represent dynamic environment. A potential archive of eastern environmental intertidal mussel species Mytilus californianus . Archaeologists have collected copious stable isotopic (δ 18 O δ 13 C) data M shells to study human history at California’s...
Abstract. Marine bivalve mollusk shells can offer valuable insights into past oceanographic variability and seasonality. Given its ecological archeological significance, Mytilus californianus (California mussel) presents the opportunity to examine seasonal decadal changes recorded in shell over centuries millennia. While dark–light growth bands M. could be advantageous for reconstructing environments, uncertainties remain regarding structure, environmental controls of dark–light-band...
Abstract. The shells of marine invertebrates can serve as high-resolution records oceanographic and atmospheric change through time. In particular, oxygen carbon isotope analyses nearshore calcifiers that grow by accretion over their lifespans provide seasonal environmental conditions. Archaeological shell middens generated Indigenous communities along the northwest coast North America contain harvested multiple seasons for millennia. These middens, well archival modern shells, have...

Abstract. The shells of marine invertebrates can serve as high-resolution records oceanographic and atmospheric change through time. In particular, oxygen carbon isotope analyses nearshore calcifiers that grow by accretion over their lifespans provide seasonal environmental conditions. Archaeological shell middens generated Indigenous communities along the Northeast Pacific coast contain harvested multiple seasons for millennia. These middens, well archival modern shells, have potential to...
