Integrating floral trait and flowering time distribution patterns help reveal a more dynamic nature of co-flowering community assembly processes

Victor Parra-Tabla, Cristopher Albor-Pinto & Gerardo Arceo-Gómez
Species’ floral traits and flowering times are known to be the major drivers of pollinator-mediated plant-plant interactions in diverse co-flowering communities. However, their simultaneous role in mediating plant community assembly and plant-pollinator interactions is still poorly understood. Since not all species flower at the same time, inference of facilitative and competitive interactions based on floral trait distribution patterns should account for fine phenological structure (intensity of flowering overlap) within co-flowering communities. Such an approach may...

Rural Appalachia Battling the Intersection of Two Crises

Margaret Miller, Rebekah Rollston, Kate E. Beatty & Michael Meit
During the COVID-19 pandemic, rural Appalachia is at great risk of unforeseen side effects including increased mortality from substance use disorders (SUDs). People living with SUDs are at increased risk for both exposure to and poor outcomes from COVID infection. The economic impacts of COVID-19 must also be considered. As rural Appalachia combats the substance use crisis amidst the COVID-19 pandemic, the geographic economic, health and social inequities within our region must be considered. As...

Caught in a bottleneck: Habitat loss for woolly mammoths in central North America and the ice-free corridor during the last deglaciation

Yue Wang, Chris Widga, Russell Graham, Jenny McGuire, Warren Porter, David Wårlind & John Williams
The dataset is to describe the habitat structure and bioenergetic characteristics of woolly mammoths (Mammuthus primigenius) in North America during the last deglaciation between 15 and 10 ka. The habitat structure includes fractional woody cover (FWC) and net primary productivity (NPP) for 20 plant functional types (PFTs). NPP is based on the dynamic vegetation model LPJ-GUESS (LPJG). FWC is based on LPJ-GUESS and fossil pollen records in the Neotoma Paleoecology Database. The bioenergetic characteristics of...

Pollen transfer networks reveal alien species as main heterospecific pollen donors with fitness consequences for natives

Victor Parra-Tabla, Conchita Alonso, Tia-Lynn Ashman, Robert Raguso, Cristopher Albor, Paula Sosenski, Diego Carmona & Gerardo Arceo-Gómez
The ecological dynamics of co-flowering communities are largely mediated by pollinators. However, current understanding of pollinator-mediated interactions primarily relies on how co-flowering plants influence attraction of shared pollinators, and much less is known about plan-plant interactions that occur via heterospecific pollen (HP) transfer. Invaded communities in particular can be highly affected by the transfer of alien pollen, but the strength, drivers, and fitness consequences of these interactions at a community scale are not well understood....

Breaking Free from Thermodynamic Constraints: Thermal Acclimation and Metabolic Compensation in a freshwater zooplankton species

Lev Yampolsky, Bret Coggins, Cora E. Anderson, A. Catherine Pearson, Rajib Hasan, Millicent N. Ekwudo & Joseph R Bidwell
Ectothermic organisms' respiration rates are largely controlled by environment temperatures and the ability to meet metabolic demands at high temperatures sometimes sets their upper thermal limit. Organisms are hypothesized to exhibit acclimatory effects, adjusting their metabolism and physiology by deceleration of metabolic processes including respiration below Arrhenius expectations based in temperature alone. Such deceleration is termed metabolic compensation. We test the hypothesis that either heritable (among genotypes) or plastic (between acclimation regimes) heat tolerance differences...
