Data from: Osteosarcopenia in reproductive-aged women with polycystic ovary syndrome: a multicenter case-control study

Maryam Kazemi, Brittany Jarrett, Stephen Parry, Anna Thalacker-Mercer, Kathleen Hoeger & Steven Spandorfer
Context: Osteosarcopenia (loss of skeletal muscle and bone mass and/or function usually associated with aging) shares pathophysiological mechanisms with polycystic ovary syndrome (PCOS). However, the relationship between osteosarcopenia and PCOS remains unclear. Objective: We evaluated skeletal muscle index% (SMI%=[appendicular muscle mass/weight {kg}]×100) and bone mineral density (BMD) in PCOS (hyperandrogenism+oligoamenorrhea), and contrasted these musculoskeletal markers against 3 reproductive phenotypes: (1) HA (hyperandrogenism+eumenorrhea); (2) OA (normoandrogenic+oligoamenorrhea) and, (3) controls (normoandrogenic+eumenorrhea). Endocrine predictors of SMI% and BMD...

After Decades of Suburban Deer Research and Management in the Eastern United States: Where Do We Go From Here?

Paul D. Curtis
State wildlife agencies have regulatory authority and oversight over deer (Cervidae) management in the United States. However, increased urban sprawl and overabundant deer populations have created increased human–deer conflicts. Because of the growing controversy surrounding the use of traditional management practices such as regulated hunting in suburban areas in the eastern United States, managers are now using specialized tools and management approaches to reduce deer conflicts in urban areas. However, this has created new challenges...

Data from: Partners coordinate territorial defense against simulated intruders in a duetting ovenbird

Pedro Diniz, Gianlucca Rech, Pedro Ribeiro, Michael Webster & Regina Macedo
Duets in breeding pairs may reflect a situation of conflict, whereby an individual answers its partner’s song as a form of unilateral acoustic mate guarding or, alternatively, it may reflect cooperation, when individuals share in territory defense or safeguard the partnership. The degree of coordination between the sexes when responding to solo versus paired intruders may elucidate the function of songs in duets. We examined this issue in a study with rufous horneros (Furnarius rufus),...

Habitat transitions alter the adaptive landscape and shape phenotypic evolution in needlefishes (Belonidae)

Matthew Kolmann, Michael D. Burns, Justin Y. K. Ng, Nathan R. Lovjoy & Devin D. Bloom
Habitat occupancy can have a profound influence on macroevolutionary dynamics, and a switch in major habitat type may alter the evolutionary trajectory of a lineage. In this study we investigate how evolutionary transitions between marine and freshwater habitats affect macroevolutionary adaptive landscapes, using needlefishes (Belonidae) as a model system. We examined the evolution of body shape and size in marine and freshwater needlefishes and tested for phenotypic change in response to transitions between habitats. Using...

Social learning of acoustic anti-predator cues occurs between wild bird species

Sara Keen
In many species, individuals gather information about their environment both through direct experience and through information obtained from others. Social learning, or the acquisition of information from others, can occur both within and between species and may facilitate the rapid spread of antipredator behaviour. Within birds, acoustic signals are frequently used to alert others to the presence of predators, and individuals can quickly learn to associate novel acoustic cues with predation risk. However, few studies...

Data from: Nocturnal foraging lifts time-constraints in winter for migratory geese but hardly speeds up fueling

Thomas Lameris, Adriaan Dokter, Henk Van Der Jeugd, Willem Bouten, Jasper Koster, Stefan Sand, Coen Westerduin & Bart Nolet
Climate warming advances the optimal timing of breeding for many animals. For migrants to start breeding earlier, a concurrent advancement of migration is required, including pre-migratory fueling of energy reserves. We investigate whether barnacle geese are time-constrained during pre-migratory fueling and whether there is potential to advance or shorten the fueling period to allow an earlier migratory departure. We equipped barnacle geese with GPS-trackers and accelerometers to remotely record birds’ behavior, from which we calculated...

Are you my baby? Testing whether paternity affects behavior of cobreeder male acorn woodpeckers

Walter Koenig, Joseph Haydock, Hannah Dugdale & Eric Walters
Natural selection is expected to favor males that invest more in offspring they sire. We investigated the relationship between paternity and male behavior in the acorn woodpecker (Melanerpes formicivorus), cooperative breeders that live in family groups including offspring that remain on their natal territory, sometimes for years, and cobreeders of both sexes. Regardless of group composition, only one communal nest is attended at a time. Whereas cobreeding females share maternity equally, one male often sires...

St Kitts Mosquito Survey and Model November 2017 to March 2019

Matthew Valentine, Courtney Murdock, Brenda Ciraola, Greg Jacobs, Patrick Kelly & Charlie Arnot
Background: High quality mosquito surveys that collect fine resolution local data on mosquito species’ abundances provide baseline data to help us understand potential host-pathogen-mosquito relationships, accurately predict disease transmission, and target mosquito control efforts in areas at risk of mosquito borne diseases. Methods: As part of an investigation into arboviral sylvatic cycles on the Caribbean island of St. Kitts, we carried out an island wide mosquito survey from November 2017 to March 2019. Using Biogents...

Data from: Testosterone regulates CYP2J19-linked carotenoid signal expression in male red-backed fairywrens (Malurus melanocephalus)

Sarah Khalil, Joseph Welklin, Kevin McGraw, Jordan Boersma, Hubert Schwabl, Michael Webster & Jordan Karubian
Carotenoid pigments produce most red, orange, and yellow colours in vertebrates. This coloration can serve as an honest signal of quality that mediates social and mating interactions, but our understanding of the underlying mechanisms that control carotenoid signal production, including how different physiological pathways interact to shape and maintain these signals, remains incomplete. We investigated the role of testosterone in mediating gene expression associated with a red plumage sexual signal in red-backed fairywrens (Malurus melanocephalus)....

Unsupervised acoustic classification of individual gibbon females and the implications for passive acoustic monitoring

Dena Clink & Holger Klinck
1. Passive acoustic monitoring (PAM) has the potential to greatly improve our ability to monitor cryptic yet vocal animals. Advances in automated signal detection have increased the scope of PAM, but distinguishing between individuals— which is necessary for density estimation— remains a major challenge. When individual identity is known, supervised classification techniques can be used to distinguish between individuals. Supervised methods require labeled training data, whereas unsupervised techniques do not. If the acoustic signals of...

Data on long-term demographic information for Alliaria petiolata in eastern North America

Bernd Blossey, Victoria Nuzzo, Andrea Dávalos, Mark Mayer, Richard Dunbar, Douglas Landis, Jeffrey Evans & Bill Minter
While biological invasions have the potential for large negative impacts on local communities and ecological interactions, increasing evidence suggests that species once considered major problems can decline over time. Declines often appear driven by natural enemies, diseases, or evolutionary adaptations that selectively reduce populations of naturalized species and their impacts. Using permanent long-term monitoring locations, we document declines of Alliaria petiolata (garlic mustard) in eastern North America with distinct local and regional dynamics as a...

A place to land: spatiotemporal drivers of stopover habitat use by migrating birds

Emily Cohen, Jeffrey Buler, Kyle Horton, Andrew Farnsworth, Peter Marra, Hannah Clipp, Jaclyn Smolinsky & Daniel Sheldon
Migrating birds require en route habitats to rest and refuel. Yet habitat use has never been integrated with passage to understand factors that determine where and when birds stopover during spring and autumn migration. Here, we introduce the stopover-to-passage ratio (SPR), the percentage of passage migrants that stop in an area, and use eight years of data from 12 weather surveillance radars to estimate over 50% SPR during spring and autumn through the Gulf of...

Data from: Evolved phenological cueing strategies show variable responses to climate change

Collin B. Edwards & Louie H. Yang
Several studies have documented a global pattern of phenological advancement that is consistent with ongoing climate change. However, the magnitude of these phenological shifts is highly variable across taxa and locations. This variability of phenological responses has been difficult to explain mechanistically. To examine how the evolution of multi-trait cueing strategies could produce variable responses to climate change, we constructed a model in which organisms evolve strategies that integrate multiple environmental cues to inform anticipatory...

Herbivory Improves the Fitness of Predatory Beetles

Todd Ugine, Avneet Nagra, Robert Grebenok, Spencer Behmer & John Losey
While many predatory arthropods consume non-prey foods from lower trophic levels, little is known about what drives the shift from predator to omnivore. Predatory lady beetles often consume non-prey foods like plant foliage and pollen. One species, Coccinella septempunctata, eats foliage to redress sterol deficits caused by eating sterol-deficient prey. Here we explore how omnivory benefits lady beetle fitness. We reared seven species of lady beetles – from five genera distributed across the tribe Coccinellini...

Data from: Testing the greater male variability hypothesis: male mountain chickadees exhibit larger variation in reversal learning compared to females

Carrie Branch, Ben Sonnenberg, Angela Pitera, Lauren Benedict, Dovid Kozlovsky, Eli Bridge & Vladimir Pravosudov
The ‘greater male variability hypothesis’ predicts that males exhibit larger ranges of variation in cognitive performance compared to females, however, support for this hypothesis has come exclusively from studies of humans. This scenario aligns with the fact that the vast majority of the literature assessing sex differences in cognition is based on studies of humans and a few other mammals. In order to elucidate the underpinnings of cognitive variation and the potential for fitness consequences,...

Raw data used in A unified framework for herbivore-to-producer biomass ratio reveals the relative influence of four ecological factor

Jotaro Urabe, Takehiro Kazama, Masato Yamamichi, Kotaro Tokita, Xuwang Yin, Izumi Katano, Hideyuki Doi, Takehito YOSHIDA & Nelson Hairston
The biomass ratio of herbivores to primary producers reflects the structure of a community. Four primary factors have been proposed to affect this ratio, including production rate, defense traits and nutrient contents of producers, and predation by carnivores. However, identifying the joint effects of these factors across natural communities has been elusive, in part because of the lack of a framework for examining their effects simultaneously. Here, we develop a framework based on Lotka-Volterra equations...

Convergence, parallelism, and function of extreme parietal callus in diverse groups of Cenozoic Gastropoda

Carlie Pietsch, Brendan Anderson, Lauren Maistros, Ethan Padalino & Warren Allmon
We use SEM imaging to examine the shell microstructure of fossil and living species in five families of caenogastropods (Strombidae, Volutidae, Olividae, Pseudolividae, and Ancillariidae) to determine whether parallel or convergent evolution is responsible for the development of a unique caenogastropod trait, the extreme parietal callus. The extreme parietal callus is defined as a substantial thickening of both the spire callus and the callus on the ventral shell surface such that it covers 50% or...

Data from: Landscape-dependent effects of varietal mixtures on insect pest control and implications for farmer profits

Lauren Snyder, Miguel Gomez, Erika Mudrak & Alison Power
Intraspecific plant diversity can significantly impact insect herbivore populations in natural systems. Yet, its role as an insect pest control strategy in agriculture has received less attention, and little is known about which crop traits are important to herbivores in different landscape contexts. Moreover, empirical economic analyses on the cost-effectiveness of varietal mixtures is lacking. We used varietal mixtures of Brassica oleracea crops on working farms to examine how two metrics of intraspecific crop diversity—varietal...

Coastal urbanization influences human pathogens and microdebris contamination in seafood

Raechel Littman, Evan Fiorenza, Amelia Wenger, Kathryn Berry, Jeroen Van De Water, Lily Nguyen, Soe Tint Aung, Daniel Parker, Douglas Rader, C. Drew Harvell & Joleah Lamb
Seafood is one of the leading imported products implicated in foodborne outbreaks worldwide. Coastal marine environments are being increasingly subjected to reduced water quality from urbanization and leading to contamination of important fishery species. Given the importance of seafood exchanged as a global protein source, it is imperative to maintain seafood safety worldwide. To illustrate the potential health risks associated with urbanization in a coastal environment, we use next-generation high-throughput amplicon sequencing of the 16S...

LeafByte: A mobile application that measures leaf area and herbivory quickly and accurately

Zoe Getman-Pickering, Adam Campbell, Julie Davis, Nicholas Aflitto, Ari Grele, Todd Ugine, Zoe L. Getman‐Pickering, Julie K. Davis & Todd A. Ugine
In both basic and applied studies, quantification of herbivory on foliage is a key metric in characterizing plant-herbivore interactions, which underpin many ecological, evolutionary, and agricultural processes. Current methods of quantifying herbivory are slow or inaccurate. We present LeafByte, a free iOS application for measuring leaf area and herbivory. LeafByte can save data automatically, read and record barcodes, handle both light and dark colored plant tissue, and be used non-destructively. We evaluate its accuracy and...

Data from: Plant-type dominates fine-root C:N:P stoichiometry across China: a meta-analysis

Zhiqiang Wang, Shiqi Lv, Hui Song, Mingcheng Wang, Qi Zhao, Heng Huang & Karl Niklas
Aim: Fine roots play an important role in biogeochemical cycling in terrestrial ecosystems. However, our understanding of large scale biogeographic patterns and drivers of fine-root C:N:P stoichiometry is extremely limited. Location: China. Methods: We compiled data for fine-root carbon (C), nitrogen (N) and phosphorus (P) concentrations at 165 sites across China to explore large-scale biogeographic patterns and drivers of fine-root C:N:P stoichiometry. Results: The geometric means of fine-root C, N, and P concentrations were 448.81...

Data from: Show me you care: female mate choice based on egg attendance rather than male or territorial traits

Anyelet Valencia-Aguilar, Kelly R. Zamudio, Célio F.B. Haddad, Steve M. Bogdanowicz & Cynthia P.A. Prado
Female mate choice is often based on male traits, including signals or behaviors, and/or the quality of a male’s territory. In species with obligate paternal care, where care directly affects offspring survival, females may also base their mate choices on the quality of a sire’s care. Here, we quantified male reproductive success in a natural population of the glassfrog Hyalinobatrachium cappellei, a species with male parental care, to determine the influence of territory quality, male...
