Data from: Comparing the prediction of joint species distribution models with respect to characteristics of sampling data

Chongliang Zhang, Yong Chen, Binduo Xu, Ying Xue & Yiping Ren
Biotic interactions have been rarely included in traditional species distribution models, wherein Joint Species Distribution Models (JSDMs) emerge as a feasible approach to incorporate environmental factors and interspecific interactions simultaneously, making it a powerful tool for analyzing the structure and assembly processes of biotic communities. However, the predictability and statistical robustness of JSDMs are largely unknown because of the lack of research efforts for those newly developed models. This study systematically evaluated the performances of...

Data from: Experimental evidence of long-term reproductive costs in a colonial nesting seabird

Aly McKnight, Erik J. Blomberg, Gregory H. Golet, David B. Irons, Cynthia S. Loftin & Shawn T. McKInney
Trade-offs between current and future reproduction are central to the evolution of life histories. Experiments that manipulate brood size provide an effective approach to investigating future costs of current reproduction. Most manipulative studies to date, however, have addressed only the short-term effects of brood size manipulation. Our goal was to determine whether survival or breeding costs of reproduction in a long-lived species manifest beyond the subsequent breeding season. To this end, we investigated long-term survival...

Data from: Discovery and exploitation of a natural ecological trap for a mosquito disease vector

Allison M. Gardner, Ephantus J. Muturi & Brian F. Allan
Ecological traps occur due to a mismatch between a habitat’s attractiveness and quality, wherein organisms show preference for low-quality habitats over other available high-quality habitats. Our previous research identified leaf litter from common blackberry (Rubus allegheniensis) as a natural ecological trap for an important vector for West Nile virus (Culex pipiens), attracting mosquitoes to oviposit in habitats deleterious to the survival of their larvae. Here we demonstrate that manipulation of leaf litter in stormwater catch...

Data from: New Guinea bone daggers were engineered to preserve social prestige

Nathaniel J. Dominy, Samuel T. Mills, Christopher M. Yakacki, Paul B. Roscoe & R. Dana Carpenter
Bone daggers were once widespread in New Guinea. Their purpose was both symbolic and utilitarian; they functioned as objects of artistic expression with the primary function of stabbing and killing people at close quarters. Most daggers were shaped from the tibiotarsus of cassowaries, but daggers shaped from the femora of respected men carried greater social prestige. The greater cross-sectional curvature of human bone daggers indicates superior strength, but the material properties of cassowary bone are...

Data from: Local environment, not local adaptation, drives leaf-out phenology in common gardens along an elevational gradient in Acadia National Park, Maine

Caitlin N. McDonough MacKenzie, Richard B. Primack, Abraham J. Miller-Rushing & Caitlin McDonough MacKenzie
PREMISE OF THE STUDY: Climate-driven changes in phenology are substantially affecting ecological relationships and ecosystem processes. The role of variation among species has received particular attention; for example, variation among species’ phenological responses to climate can disrupt trophic interactions and can influence plant performance. Variation within species in phenological responses to climate, however, has received much less attention, despite its potential role in ecological interactions and local adaptation to climate change. METHODS: We constructed three...

Data from: Genomic signatures of population bottleneck and recovery in Northwest Atlantic pinnipeds

Kristina M. Cammen, Thomas F. Schultz, W. Don Bowen, Michael O. Hammill, Wendy B. Puryear, Jonathan Runstadler, Frederick W. Wenzel, Stephanie A. Wood & Michael Kinnison
Population increases over the past several decades provide natural settings in which to study the evolutionary processes that occur during bottleneck, growth, and spatial expansion. We used parallel natural experiments of historical decline and subsequent recovery in two sympatric pinniped species in the Northwest Atlantic, the gray seal (Halichoerus grypus atlantica) and harbor seal (Phoca vitulina vitulina), to study the impact of recent demographic change in genomic diversity. Using restriction site‐associated DNA sequencing, we assessed...

Data from: Seascapes as drivers of herbivore assemblages in coral reef ecosystems

George Roff, Sonia Bejarano, Mark Priest, Alyssa Marshell, Iliana Chollett, Robert S. Steneck, Christopher Doropoulos, Yimnang Golbuu & Peter J. Mumby
Herbivorous fish maintain a critical ecosystem function on coral reefs by grazing algae and maintaining highly productive algal turf assemblages. Current paradigms implicate habitat complexity, predation and primary productivity as major drivers of the distribution and abundance of herbivorous fish, yet little is known about the relative contribution of these factors. Here, we compare bottom-up and top-down drivers of notional herbivore assemblages across an environmental gradient of wave exposure in the Palau archipelago. We surveyed...

Data from: Globally invasive genotypes of the amphibian chytrid outcompete an enzootic lineage in coinfections

Thomas S. Jenkinson, David Rodriguez, Rebecca A. Clemons, Lucas A. Michelotti, Kelly R. Zamudio, Luís Felipe Toledo, Joyce E. Longcore & Timothy Y. James
Competition between genotypes is likely to be a key driver of pathogen evolution, particularly following a geographic invasion by distant strains. Theory predicts that competition between disease strains will result in the most virulent strain persisting. Despite its evolutionary implications, the role of strain competition in shaping populations remains untested for most pathogens. We experimentally investigated the in vivo competitive differences between two divergent lineages of the amphibian-killing chytrid fungus (Batrachochytrium dendrobatidis, Bd). These Bd...

Data from: Grazing effect on grasslands escalated by abnormal precipitations in Inner Mongolia

Maowei Liang, Jiquan Chen, Elise S. Gornish, Zhiyong Li, Xue Bai & Cunzhu Liang
1. Grazing effects on arid and semi-arid grasslands can be constrained by aridity. Plant functional groups (PFGs) are the most basic component of community structure (CS) and biodiversity & ecosystem function (BEF). They have been suggested as identity-dependent in quantifying the responses to grazing intensity and drought severity. Here we examine how the relationships among PFGs, CS, BEF, and grazing intensity are driven by climatic drought. 2. We conducted a manipulative experiment with three grazing...

Data from: Bidirectional adaptive introgression between two ecologically divergent sparrow species

Jennifer Walsh, Adrienne I. Kovach, Brian Justin Olsen, W. Gregory Shriver & Irby J. Lovette
Natural hybrid zones can be used to dissect the mechanisms driving key evolutionary processes by allowing us to identify genomic regions important for establishing reproductive isolation and that allow for transfer of adaptive variation. We leverage whole-genome data in a system where two bird species, the saltmarsh (Ammospiza caudacutus) and Nelson’s (A. nelsoni) sparrow, hybridize despite their relatively high background genetic differentiation and past ecological divergence. Adaptive introgression is plausible in this system because Nelson’s...

Data from: Local adaptation reduces the metabolic cost of environmental warming

Emma R. Moffett, David C. Fryxell, Eric P. Palkovacs, Michael T. Kinnison & Kevin S. Simon
Metabolism shapes the ecosystem role of organisms by dictating their energy demand and nutrient recycling potential. Metabolic theory (MTE) predicts consumer metabolic and recycling rates will rise in a warming world, especially if body size declines, but it ignores potential for adaptation. We measured metabolic and nutrient excretion rates of individuals from populations of a globally invasive fish that recently colonized a wide temperature range (19-37°C) on two continents. Fish body size declined across our...

Data from: Consequences of breeding system for body condition and survival throughout the annual cycle of tidal marsh sparrows

Alyssa Borowske, Christopher R. Field, Katharine J. Ruskin & Chris S. Elphick
An individual’s body condition and probability of survival can change throughout the annual cycle, based on the combined effects of many factors, including reproductive investment during breeding, colder temperatures during winter, and elevated risks during migration. We evaluated body condition and survival during breeding and non-breeding periods in two closely related species with notably different reproductive systems. Male and female saltmarsh sparrows (Ammodramus caudacutus) represent extremes in parental care: males perform none, leaving females to...
