Jones, Jessica Hines, Mark Vellend, Conor Waldock & Mary O'Connor
Humans have elevated global extinction rates and thus lowered global-scale species richness. However, there is no a priori reason to expect that losses of global species richness should always, or even often, trickle down to losses of species richness at regional and local scales, even though this relationship is often assumed. Here, we show that scale can modulate our estimates of species richness change through time in the face of anthropogenic pressures, but not in...

Data from: Phenotypic and community consequences of captive propagation in mosquitofish

Zachary T. Wood, David C. Fryxell, Rebecca R. Robinson, Eric P. Palkovacs & Michael T. Kinnison
1. Captive propagation can lead to phenotypic change in fish populations, but the broader community-level consequences of captive phenotypes remain largely unknown. 2. Here we investigate the degree to which captive propagation alters the phenotypes and ecological roles of fish stocked into wild communities. We focus on captive propagation of western mosquitofish (Gambusia affinis) for biocontrol, which represents one of the largest-scale production efforts for any fish released into the wild. 3. Captive propagation in...

Data from: The downed and dead wood inventory of forests in the United States

Christopher W. Woodall, Vicente J. Monleon, Shawn Fraver, Matthew B. Russell, Mark H. Hatfield, John L. Campbell & Grant M. Domke
The quantity and condition of downed dead wood (DDW) is emerging as a major factor governing forest ecosystem processes such as carbon cycling, fire behavior, and tree regeneration. Despite this, systematic inventories of DDW are sparse if not absent across major forest biomes. The Forest Inventory and Analysis program of the United States (US) Forest Service has conducted an annual DDW inventory on all coterminous US forest land since 2002 (~1 plot per 38,850 ha),...

Data from: Trails-as-transects: phenology monitoring across heterogeneous microclimates in Acadia National Park, Maine

Caitlin McDonough MacKenzie, Abraham J. Miller-Rushing & Richard B. Primack
Climate‐driven shifts in phenology, which are being observed worldwide, affect ecosystem services, trophic interactions, and community composition, presenting challenges to managers in protected areas. Resource management benefits from local, species‐specific phenology information. However, phenology monitoring programs in heterogeneous landscapes typically require serendipitous historical records or many years of contemporary data before trends in phenological responses to changes in climate can be analyzed. Here, we used a trails‐as‐transects approach to rapidly accumulate monitoring data across environmental...

Data from: Phenological mismatch with trees reduces wildflower carbon budgets

J. Mason Heberling, Caitlin McDonough MacKenzie, Jason D. Fridley, Susan Kalisz & Richard B. Primack
Interacting species can respond differently to climate change, causing unexpected consequences. Many understory wildflowers in deciduous forests leaf out and flower in the spring when light availability is highest before overstory canopy closure. Therefore, different phenological responses by understory and overstory species to increased spring temperature could have significant ecological implications. Pairing contemporary data with historical observations initiated by Henry David Thoreau (1850s), we found that overstory tree leaf out is more responsive to increased...

Data from: Repeat disturbances have cumulative impacts on stream communities

Jessica M. Haghkerdar, Jack R. McLachlan, Alexis Ireland & Hamish S. Greig
(1) Climate change has altered disturbance regimes in many ecosystems, and predictions show that these trends are likely to continue. The frequency of disturbance events plays a particularly important role in communities by selecting for disturbance-tolerant taxa. (2) However, ecologists have yet to disentangle the influence of disturbance frequency per se and time since last disturbance, because more frequently disturbed systems have also usually been disturbed more recently. Our understanding of the effects of repeated...

Data from: Contrasting drivers of diversification rates on islands and continents across three Passerine families

Meaghan Conway & Brian Olsen
Rates of diversification vary greatly among taxa. Understanding how species-specific traits influence speciation rates will help elucidate mechanisms driving the production and maintenance of biodiversity over broad spatiotemporal scales. Ecological specialization and range size are two characteristics thought to predict differences in speciation rates among clades, yet each mechanism predicts both increases and decreases in speciation. We estimate a continuous index of specialization using avian bill morphology. We determine the relative effect of specialization and...

A classification framework for Bacillus anthracis defined by global genomic structure

Spencer Bruce, Nicholas Schiraldi, Pauline Kamath, W. Ryan Easterday & Wendy Turner
Bacillus anthracis, the causative agent of anthrax, is a considerable global health threat affecting wildlife, livestock, and the general public. In this study whole-genome sequence analysis of over 350 B. anthracis isolates was used to establish a new high-resolution global genotyping framework that is both biogeographically informative, and compatible with multiple genomic assays. The data presented in this study shed new light on the diverse global dissemination of this species and indicate that many lineages...
