Historical ecosystem models can serve as a baseline for indicator-based assessment: the North Sea
Frontiers in Marine ScienceKnowledge of past ecosystems is essential to understand how marine ecosystems have changed under human pressure. This understanding is critical for the effective management of marine ecosystems today. However, there has been limited effort to investigate

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State
American Journal of Botany, EarlyView.Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Could There Have Been 1.5 Million Bighorn Sheep in 1850? Most Likely Not!
WildThere is little question that the distribution and numbers of large mammals have been altered by human activities. In North America, native ungulates have declined substantially since the mid-1800s. There is no baseline, however, against which to measure

A leaf phenomics approach for estimating belowground traits in North American licorice
American Journal of Botany, EarlyView.Abstract Premise Selective breeding over thousands of years has prioritized aboveground yield, with little regard for changes belowground. Roots underpin plant growth and resilience, but our knowledge of these critical structures lags behind that of aboveground structures.

MycobiologyFungal forays have been conducted for more than 150 years, providing valuable, but underutilized, sets of records for studies of fungal ecology. Although foray records have been used to study species composition and phenological change, their potential ...

Climate and seed mass drive intraspecific variation in seed longevity in storage
American Journal of Botany, EarlyView.Abstract Premise Conservation seed banks are essential for ex situ plant conservation, but stored seeds slowly deteriorate and lose viability. Seed longevity in storage is determined by the initial seed viability and the rate of seed viability loss. The rate of seed viability loss in storage varies between species and possibly between populations or ...

American Journal of Community Psychology, EarlyView.Abstract If sexual assault survivors report the assault to the criminal legal system, they often need informal support from family and friends throughout the long and frequently retraumatizing process of investigation and prosecution. This study is part of a long‐term community‐based participatory action research project in a predominately Black ...
