Seasonal body mass dynamics mediate life-history trade-offs in a hibernating mammal Seasonal body mass dynamics mediate life-history trade-offs in a hibernating mammal

1. Energetic acquisition and growth are key traits that affect demography and life-history strategies. Many animals that live in seasonal environments in which food availability fluctuates store energy endogenously as fat in anticipation of food shortage. Fat-storing mammalian hibernators are an extreme example of this strategy where the optimal resolution of resource allocation trade...

Weather drivers of reproductive variability in perennial plants and their implications for climate change risks Weather drivers of reproductive variability in perennial plants and their implications for climate change risks

Seed production in perennial plants often shows strong year-to-year variation, a phenomenon known as masting. Masting is typically adaptive and driven by weather cues that synchronize reproduction by promoting or suppressing flowering and seed set. These cues, involving temperature, precipitation, and drought, differ across species and regions, yet a global synthesis is needed...

Rare earth element-mineralized carbonatite in the Bear Lodge Alkaline Complex, USA—Ore genesis implications from fluid inclusion characterization Rare earth element-mineralized carbonatite in the Bear Lodge Alkaline Complex, USA—Ore genesis implications from fluid inclusion characterization

Rare earth element (REE) resources of the Bear Lodge Alkaline Complex, Wyoming, are hosted in variably leached carbonatite spatially related to diatreme breccia pipes. We investigated the genesis of REE and lesser-known gold resources through fluid inclusion analysis of carbonatite, fluorite breccia, and smoky quartz vein samples. Physicochemical characteristics of inclusion-trapped...

Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids

Vicuñas (Vicugna vicugna) and guanacos (Lama guanicoe) are the two species of wild South American camelids whose distributions range from Peru to northern Argentina and southern Peru to southern Argentina, respectively. Listed as critically endangered in the 1960s due to poaching, vicuña numbers had been gradually recovering; however, new concerns about population stability have arisen...

Advancing climate adaptation for inland fish and fisheries Advancing climate adaptation for inland fish and fisheries

Climate change was barely a blip on the radar for inland fisheries management 20 years ago. Today, it's a central focus. A 2016 paper helped shift conversations, sparked adaptation efforts across fisheries management. The future is still uncertain, but adaptation is key to sustaining these important resources.

Guidelines for producing integrated 210Pb and 14C age-models Guidelines for producing integrated 210Pb and 14C age-models

Accurate reconstructions of past environmental changes are crucial in paleoecological research and require reliable chronologies of sedimentary archives. Establishing robust age-models and obtaining the most appropriate proxies for analysis is a complex scientific endeavor, requiring extensive resources and collaboration among specialists, including radiochronologists. Radiometric dating...
