Data from: Integrating tracking and resight data enables unbiased inferences about migratory connectivity and winter range survival from archival tagsClark Rushing, Aimee Van Tatenhove, Andrew Sharp, Viviana Ruiz-Gutierrez, Mary Freeman, Paul Sykes, Aaron Given & Scott Sillett
Archival geolocators have transformed the study of small, migratory organisms but analysis of data from these devices requires bias correction because tags are only recovered from individuals that survive and are re-captured at their tagging location. Data and code provided in this repository can be used to replicate the simulation and Painted Bunting case study results presented by Rushing et al. (2021) showing that integrating geolocator recovery data and mark–resight data enables unbiased estimates of...
Cytotype and genotype predict mortality and recruitment in Colorado quaking aspen (Populus tremuloides)Benjamin Blonder, Courtenay Ray, James Walton, Marco Castaneda, K. Dana Chadwick, Michael Clyne, Pierre Gaüzere, Lars Iversen, Madison Lusk, G. Richard Strimbeck, Savannah Troy & Karen Mock
Species responses to climate change depend on environment, genetics, and interactions among these factors. Intraspecific cytotype (ploidy level) variation is a common type of genetic variation in many species. However, the importance of intraspecific cytotype variation in determining demography across environments is poorly known. We studied the tree species quaking aspen (Populus tremuloides), which occurs in diploid and triploid cytotypes. This widespread species is experiencing contractions in its western range, which could potentially be linked...
Data from: Relative bee abundance varies by collection method and flowering richness: implications for understanding patterns in bee community dataPhilip Hahn, Marirose Kuhlman, Skylar Burrows, Dan Mummey & Philip Ramsey
Pollination by wild bees is a vital ecosystem process in natural and managed systems. Recent declines in wild bee populations have led to increases in conservation actions and monitoring of bee communities. Pan traps are a commonly used sampling method for monitoring bee populations due to their efficiency and low cost. However, potential biases inherent in different sampling techniques may result in misleading characterizations of bee communities across space and time. In this paper, we...
Genomic time-series data show that gene flow maintains high genetic diversity despite substantial genetic drift in a butterfly speciesZachariah Gompert, Amy Springer, Megan Brady, Samridhi Chaturvedi & Lauren Lucas
Effective population size affects the efficacy of selection, rate of evolution by drift, and neutral diversity levels. When species are subdivided into multiple populations connected by gene flow, evolutionary processes can depend on global or local effective population sizes. Theory predicts that high levels of diversity might be maintained by gene flow, even very low levels of gene flow, consistent with species long-term effective population size, but tests of this idea are mostly lacking. Here,...
The effect of plant invasion on soil microbial carbon-use efficiency in semiarid grasslands of the Rocky Mountain WestMegan Nasto, Morgan McLeod, Lorinda Bullington, Ylva Lekberg & John Stark
1. Grassland ecosystems invaded by exotic plant species often exhibit substantially higher aboveground productivity and soil nitrogen (N) than the native communities they replace. These shifts are likely associated with altered microbial carbon (C) and N cycling, but we know surprisingly little about how these processes change with plant invasion. 2. Targeting four invasive plant species common in the Rocky Mountain West, we collected soils from invaded and adjacent uninvaded grassland field plots, as well...
Improving intra- and inter-annual GPP predictions by using individual-tree inventories and leaf growth dynamicsJing Fang, James Lutz, Herman Shugart, Xiaodong Yan, Wenqiang Xie & Feng Liu
Carbon sequestration is a key ecosystem service provided by forests. Inventory data based on individual trees are considered to be the most accurate method for estimating forest productivity. However, estimations of forest photosynthesis itself from inventory data remains understudied, particularly when considering the growth and development of individual trees under the background of global change. Here, we used the leaf growth process with phenology and non-structural carbohydrates (NSC) storage to revise an individual-tree based carbon...
Project reports B2Al3- cluster, which mimics triple bond N2 molecule.
Individual variation in behavior, particularly consistent among-individual differences (i.e., personality), has important ecological and evolutionary implications for population and community dynamics, trait divergence, and patterns of speciation. Nevertheless, individual variation in spatial behaviors, such as home range behavior, movement characteristics, or habitat use has yet to be incorporated into the concepts or methodologies of ecology and evolutionary biology. To evaluate evidence for the existence of consistent among-individual differences in spatial behavior – which we refer...
Data for behavioral state-dependent habitat selection analysis of translocated female greater sage-grouse, North Dakota 2018-2020Simona Picardi, Peter Coates, Jesse Kolar, Shawn O'Neil, Steven Mathews & David Dahlgren
This dataset is associated with the article, "Behavioral state-dependent habitat selection and implications for animal translocations" (Picardi et al., 2021, Journal of Applied Ecology). Post-release monitoring of translocated animals can be used to inform future translocation protocols. In particular, quantifying habitat selection of translocated individuals may help identify features that characterize suitable settlement habitat and inform the choice of future release sites; however, because translocated animals undergo post-release behavioral modification, the underlying behavioral state needs...
Polymorphism facilitates coexistence of divergent morphs (e.g., phenotypes) of the same species by minimizing intraspecific competition, especially when resources are limiting. Arctic char (Salvelinus sp.) are a Holarctic fish often forming morphologically, and sometimes genetically, divergent morphs. In this study, we assessed the morphological and genetic diversity and divergence of 263 individuals from seven populations of arctic char with varying length-frequency distributions across two distinct groups of lakes in northern Alaska. Despite close geographic proximity,...
Reproduction, although absolutely essential to a species’ persistence, is in itself challenging. As anthropogenic change increasingly affects every landscape on Earth, it is critical to understand how specific pressures impact the reproductive efforts of individuals, which directly contribute to the success or failure of populations. However, organisms rarely encounter a single burden at a time, and the interactions of environmental challenges can have compounding effects. Disentangling environmental and physiological pressures is difficult because they are...
