Data from: Corralling a black swan: natural range of variation in a forest landscape driven by rare, extreme events

Daniel C. Donato, Joshua S. Halofsky & Matthew J. Reilly
The natural range of variation (NRV) is an important reference for ecosystem management, but has been scarcely quantified for forest landscapes driven by infrequent, severe disturbances. Extreme events such as large, stand-replacing wildfires at multi-century intervals are typical for these regimes; however, data on their characteristics are inherently scarce, and, for land management, these events are commonly considered too large and unpredictable to integrate into planning efforts (the proverbial ‘Black Swan’). Here, we estimate the...

Data from: Strong dispersal limitation in post-fire regeneration of Baker cypress, a rare serotinous conifer

Jeffrey Kane, Bret McNamara & David Greene
PREMISE: Dispersal capacity primarily determines the spatial establishment patterns that drive range expansions and contractions in tree species. For Baker cypress (Hesperocyparis bakeri [(Jeps.) Bartel]), seedling establishment relies predominantly on fire events due to its cone serotiny, shade intolerance, and small seeds requiring the optimal conditions of fire-exposed, mineral soil seedbeds. METHODS: This study quantified the density and spatial distribution of post-disturbance seedlings following the 2014 Eiler fire in northern California and compared the observed...

Data from: Historical population size change and differentiation of relict populations of the endangered giant kangaroo rat

Mark J. Statham, William T. Bean, Nathan Alexander, Michael F. Westphal & Benjamin N. Sacks
From a conservation management perspective it is important to understand how genetic diversity is partitioned across a species’ range, including (1) identification of evolutionarily distinct units versus those recently isolated through anthropogenic activities and (2) the relative genetic contributions among components of fragmented (meta)populations. To address these questions, we investigated the phylogeography and metapopulation structure among relict populations of the endangered giant kangaroo rat (Dipodomys ingens) in the highly altered San Joaquin Desert Ecosystem. This...

Data from: The 15-year post-treatment response of a mixed-conifer understory plant community to thinning and burning treatments

Matthew Hurteau, Marrissa Goodwin, Malcolm North, Harold Zald & Brandon Collins
Disturbance is central to maintaining diversity in forest ecosystems. In the dry forests of the western United States, over a century of fire exclusion has altered the fire regimes of these forests, resulting in high fuel loads and a loss of plant diversity. Mechanical thinning and prescribed fire are widely used to restore structural complexity and species diversity in many western U.S. forests. While studies have shown that the reintroduction of fire into these forests...

Molecular sequencing and morphological identification reveal similar patterns in native bee communities across public and private grasslands of eastern North Dakota

Brian Darby, Russ Bryant, Abby Keller, Madison Jochim, Josephine Moe, Zoe Schreiner, Carrie Pratt, Ned H. Euliss, Mia Park, Rebecca Simmons & Clint Otto
Bees play a key role in the functioning of human-modified and natural ecosystems by pollinating agricultural crops and wild plant communities. Global pollinator conservation efforts need large-scale and long-term monitoring to detect changes in species’ demographic patterns and shifts in bee community structure. The objective of this project was to test a molecular sequencing pipeline that would utilize a commonly used locus, produce accurate and precise identifications consistent with morphological identifications, and generate data that...
