These effects, including sea ice loss, are already modifying the ecologies of the 11 species of marine mammals found in the Arctic year-round. Data from contemporary individuals are often applied to understand how these species may respond to future climate change. The inclusion of fossil data can provide greater insight into species histories. Conservation approaches are increasingly enhanced by including ancient biomolecular data such as radiocarbon age, stable isotopes, and ancient DNA. However, analytical quality is challenged by data degradation over time, lack of cross-linkage between different ancient biomolecular data, and widely varying metadata standards across fields. Here, we compile and present an open-access database of Fossil Arctic Marine Mammals (FAMM) containing nearly 3400 specimens with harmonised primary and molecular biodiversity data, providing a crucial resource to Arctic biodiversity and environmental research.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Types of Variables Collected&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;FAMM contains records and metadata of Arctic marine mammal macrofossils, including: taxonomy; geographic provenance; radiocarbon age; stable isotopes; and ancient DNA.

We use these simulations to infer arborescent vegetation cover and frame simulation differences so that they may be compared to two large-scale, well-documented community turnovers late in the LPIA, using end-member CO&lt;sub&gt;2&lt;/sub&gt; concentrations and plant types to evaluate potential feedbacks to water availability.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Simulated forest cover varied widely in global terrestrial extent, from less than 5% to greater than 65% cover.

The addition of stem physiology in this work restricts wet-adapted plants to high-precipitation regions. Expanded biogeography interacted with the prolonged water use of dry-adapted plants to reduce site water balance.

Despite their importance in driving critical ecosystem functions, the diversity and distribution of these cryptic belowground taxa remain poorly understood, particularly at broad spatial scales. Here, we used a large-scale sampling design to test the effects of (i) mean annual temperature (MAT), (ii) net primary productivity (represented by aboveground plant biomass and algal biomass), and (iii) sediment grain size (SED, representing local conditions) on the diversity of belowground organisms in coastal wetlands, with a focus on bacterial, protistan, and metazoan communities.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Location&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Coastal wetlands of China.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Time Period&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Current.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Major Taxa Studied&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Bacteria, protists and metazoa.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Method&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;We sampled 101 coastal wetlands including bare mudflat (39 sites), salt marsh (36 sites) and mangrove (26 sites). High throughput sequencing of 16S and 18S rRNA genes was conducted to examine the belowground diversity. We then applied generalised linear models to examine the relationship between environmental predictors and belowground diversities. Finally, we conducted piecewise structural equation modelling to explore both direct and indirect effects on diversities along the entire coastline.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;MAT had a significantly positive influence on surface belowground metazoan diversity, while bacterial diversity was more driven by SED. Both MAT and SED had a non-significant effect on protistan diversity.
