Conspecific attraction for conservation and management of terrestrial breeding birds: current knowledge and future research directions

Jonathon Valente, Christa LeGrande-Rolls, James Rivers, Anna Tucker, Richard Fischer & Matthew Betts
Conspecific presence can indicate the location or quality of resources, and animals settling near conspecifics often gain fitness benefits. This can result in adaptive conspecific attraction during breeding habitat selection as demonstrated in numerous terrestrial, territorial birds. There is growing interest in using simulated conspecific social cues (e.g., decoys, broadcasted vocalizations) to manage bird distributions, yet it remains unclear when this approach is likely to succeed. We reviewed published studies to evaluate whether the strength...

ISIMIP3b N-deposition input data

Jia Yang & Hanqin Tian
The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.
The ISIMIP3b part of the third simulation round is dedicated to a quantification of climate-related risks at different levels of global warming and socio-economic change. ISIMIP3b group I simulations are based on historical...

A genetic switch for male UV-iridescence in an incipient species pair

Vincent Ficarrotta, Joseph J. Hanly, Ling S. Loh, Caroline M. Francescutti, Anna Ren, Kalle Tunström, Christopher W. Wheat, Adam H. Porter, Brian A. Counterman & Arnaud Martin
Mating cues evolve rapidly and can contribute to species formation and maintenance. However, little is known about how sexual signals diverge and how this variation integrates with other barrier loci to shape the genomic landscape of reproductive isolation. Here, we elucidate the genetic basis of UV iridescence, a courtship signal that differentiates the males of Colias eurytheme butterflies from a sister species, allowing females to avoid costly heterospecific matings. Anthropogenic range expansion of the two...

Demographic responses to climate change in a threatened Arctic species

Kylee D. Dunham, Anna M. Tucker, David N. Koons, Asheber Abebe, F. Stephen Dobson & James B. Grand
The Arctic is undergoing rapid and accelerating change in response to global warming, altering biodiversity patterns and ecosystem function across the region. For Arctic endemic species, our understanding of the consequences of such change remains limited. Spectacled eiders (Somateria fischeri), a large Arctic sea duck, use remote regions in the Bering Sea, Arctic Russia, and Alaska throughout the annual cycle making it difficult to conduct comprehensive surveys or demographic studies. Listed as Threatened under the...

Cave-adapted evolution in the North American Amblyopsid fishes inferred using phylogenomics and geometric morphometrics

Pamela Hart, Matthew Niemiller, Edward Burress, Jonathan Armbruster, William Ludt & Prosanta Chakrabarty
Cave adaptation has evolved repeatedly across the Tree of Life, famously leading to pigmentation and eye degeneration and loss, yet its macroevolutionary implications remain poorly understood. We use the North American amblyopsid fishes, a family spanning a wide degree of cave adaptation, to examine the impact of cave specialization on the modes and tempo of evolution. We reconstruct evolutionary relationships using ultraconserved element loci, estimate the ancestral histories of eye-state, and examine the impact of...

Patterns of Testosterone in Male White-tailed Deer (Odocoileus virginianus): Seasonal and Lifetime Variation

Monet Gomes, Stephen Ditchkoff, Sarah Zohdy, William Gulsby & Chad Newbolt
Testosterone is strongly associated with the annual development of antlers in cervids, but. endocrine research on wild, freely breeding ungulates is often done without repeated capture of known-aged individuals. As a result, our knowledge on how testosterone fluctuates over the course of a lifetime and variation in lifetime patterns among individuals is limited. We investigated patterns of testosterone in a freely breeding population of white-tailed deer (Odocoileus virginianus) in Alabama, USA that breeds in January....

ISIMIP3a N-deposition input data

Jia Yang & Hanqin Tian
The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.
The ISIMIP3a part of the third simulation round is dedicated to i) impact model evaluation and improvement and ii) detection and attribution of observed impacts according to the framework of IPCC AR5 Working...

Data from: Application of a novel haplotype-based scan for local adaptation to study high-altitude adaptation in rhesus macaques

Zachary Szpiech, Taylor Novak, Nick Bailey & Laurie Stevison
When natural populations split and migrate to different environments, they may experience different selection pressures that can lead to local adaptation. To capture the genomic patterns of a local selective sweep, we develop XP-nSL, a genomic scan for local adaptation that compares haplotype patterns between two populations. We show that XP-nSL has power to detect ongoing and recently completed hard and soft sweeps, and we then apply this statistic to search for evidence of adaptation...

Nitrogen budget data

Tan Zou, Xin Zhang, Luis Lassaletta, Nathaniel Mueller, Francesco Tubiello, Matthew Lisk, Chaoqun Lu, Richard Conant, Christopher Dorich, James Gerber, Hanqin Tian, Tom Bruulsema, Tai Maaz, Kazuya Nishina, Benjamin Bodirsky, Alexander Popp, Lex Bouwman, Arthur Beusen, Jinfeng Chang, Petr Havlík, David Leclère, Josep Canadell, Robert Jackson, Patrick Heffer, Nathan Wanner … & Eric Davidson
Input-output estimates of nitrogen (N) on cropland are essential for improving N management and better understanding the global N cycle. Here, we compare 13 N budget datasets covering 115 countries and regions over 1961-2015. Though most datasets showed similar spatiotemporal patterns, some annual estimates varied widely among them, resulting in large ranges and uncertainty. In 2010, global medians (in Tg N yr-1) and associated min-max ranges were 73 (64-84) for global harvested crop N; 161...

Base-substitution mutation rate across the nuclear genome of Alpheus snapping shrimp and the timing of isolation by the Isthmus of Panama

Katherine Silliman, Jane Indorf, Nancy Knowlton, William Browne & Carla Hurt
The formation of the Isthmus of Panama and final closure of the Central American Seaway (CAS) provides an independent calibration point for examining the rate of DNA substitutions. This vicariant event has been widely used to estimate the substitution rate across mitochondrial genomes and to date evolutionary events in other taxonomic groups. Nuclear sequence data is increasingly being used to complement mitochondrial datasets for phylogenetic and evolutionary investigations; these studies would benefit from information regarding...

Why do insects shut their spiracles? A meta-analytic evaluation of the adaptive hypotheses of discontinuous gas exchange in insects

Seun Oladipupo
The earliest description of the discontinuous gas exchange cycle (DGC) in lepidopterous insects supported the role played by the spiracles and tracheal system in modulating the release of carbon dioxide. Further understanding led to the idea that the adaptive significance of regulated opening and closure of the spiracles is to reduce water loss (hygric hypothesis) and facilitate gaseous exchange in hyperoxia/hypoxia (chthonic hypothesis). With technological advances, other insect orders were investigated and the hygric and...

Spatial and temporal variation in phenotypes and fitness in response to developmental thermal environments

Jenna Pruett & Daniel Warner
1) Phenotypic variation within populations is influenced by the environment via plasticity and natural selection. How phenotypes respond to the environment can vary among traits, populations, and life stages in ways that can influence fitness. 2) Plastic responses during early development are particularly important because they can affect components of fitness throughout an individual’s life. Consequently, how natural selection shapes developmental plasticity could be influenced by fitness consequences across different life stages. Moreover, spatial variation...
