Background Large-river decision-makers are charged with maintaining diverse ecosystem services through unprecedented social-ecological transformations as climate change and other global stressors intensify. The interconnected, dendritic habitats of rivers, which often demarcate jurisdictional boundaries, generate complex management challenges. Here, we explore how the Resist–Accept–Direct(RAD) framework may enhance large-river management by promoting coordinated and deliberate responses to social-ecological trajectories of change. The RAD framework identifies the full decision space of potential management approaches, wherein managers may resist change to maintain historical conditions, accept change toward different conditions, or direct change to a specified future with novel conditions. In the Upper Mississippi River System, managers are facing social-ecological transformations from more frequent and extreme high-water events. We illustrate how RAD-informed basin-, reach-, and site-scale decisions could:(1) provide cross-spatial scale framing;(2) open the entire decision space of potential management approaches; and(3) enhance coordinated inter-jurisdictional management in response to the trajectory of the Upper Mississippi River *** The RAD framework helps identify plausible long-term trajectories in different reaches(or subbasins) of the river and how the associated social-ecological transformations could be managed by altering site-scale conditions. Strategic reach-scale objectives may reprioritize how, where, and when site conditions could be altered to contribute to the basin goal, given the basin's plausible trajectories of change(e.g., by coordinating action across sites to alter habitat connectivity, diversity, and redundancy in the river mosaic).Conclusions When faced with long-term systemic transformations(e.g., > 50 years), the RAD framework helps explicitly consider whether or when the basin vision or goals may no longer be achievable,

Changes in Avian Spring Arrival Dates of 115 Species in the Central Appalachians over 127 Years

Global climate change affects many facets of avian ecology, such as shifts in breeding phenology and migration patterns. Migrating bird species respond to changes in climate by shifting their temporal patterns of spring migration. However, variation in species’ responses exists based on various life history traits, which exposes some species to an increased risk of phenological mismatch. This study examined the spring arrival dates of 115 migrating species over 127 years (1889-2015) using archival sources in West Virginia, USA, making this research unique in the length of study, the high number of species studied, and the historical crowd-sourced observations analyzed. Of the 115 taxa, 45 showed significant negative slopes of spring arrival dates (arriving earlier in the spring) plotted against the year. In contrast, only nine species showed positive slopes (arriving later in the spring), albeit non-significant. The average advance of spring arrival date for all species was 1.7 days per decade, and an advance of 2.6 days per decade in species that showed significance. Arrival dates were associated with increasing spring temperatures—for each 1˚C increase, the arrival date advanced by 0.81 days/decade. Several life history traits were linked to species that advanced their first arrival dates, including a shorter distance migrated to reach wintering grounds, increasing populations, and foraging habitat. Most avian species are advancing their spring arrival dates in response to climate change. However, the implications of earlier spring arrival are unclear. We draw attention to shifts in arrival dates and wintering ranges, leading to a possible increase in overwintering in the mid-latitudes of North America.

Perspectives:Gene expression in fisheries management

Functional genes and gene expression have been connected to physiological traits linked to effective production andbroodstock selection in aquaculture, selective implications of commercial fish harvest, and adaptive changes reflected innon-commercial fish populations subject to human disturbance and climate change. Gene mapping using single nucleotide polymorphisms(SNPs) to identify functional genes, gene expression (analogue microarrays and real-time PCR), and digital sequencingtechnologies looking at RNA transcripts present new concepts and opportunities in support of effective and sustainable *** tools have been rapidly growing in aquaculture research addressing aspects of fish health, toxicology, and earlydevelopment. Genomic technologies linking effects in functional genes involved in growth, maturation and life history developmenthave been tied to selection resulting from harvest practices. Incorporating new and ever-increasing knowledge of fish genomesis opening a different perspective on local adaptation that will prove invaluable in wild fish conservation and *** of fish stocks is rapidly incorporating research on critical adaptive responses directed at the effects of human disturbanceand climate change through gene expression studies. Genomic studies of fish populations can be generally grouped intothree broad categories: 1) evolutionary genomics and biodiversity; 2) adaptive physiological responses to a changing environment;and 3) adaptive behavioral genomics and life history diversity. We review current genomic research in fisheries focusing on thosethat use microarrays to explore differences in gene expression among phenotypes and within or across populations, informationthat is critically important to the conservation offish and their relationship to
