The utility of reptile blood transcriptomes in molecular ecology

Tonia S Schwartz, Damien S Waits, Dasia Y Simpson, Amanda M Sparkman & Anne M Bronikowski
Reptiles and other non-mammalian vertebrates have transcriptionally active nucleated red blood cells. If blood transcriptomes can provide quantitative data to address questions relevant to molecular ecology, this could circumvent the need to euthanize animals to assay tissues. This would allow longitudinal sampling of animals’ responses to treatments, as well as sampling of protected taxa. We developed and annotated blood transcriptomes from six reptile species. We found on average 25,000 proteins are being transcribed in the...

Data from: Geographic variation in thermal sensitivity of early life traits in a widespread reptile

Brooke L. Bodensteiner, Daniel A. Warner, John B. Iverson, Carrie L. Milne-Zelman, Timothy S. Mitchell, Jeanine M. Refsnider & Fredric J. Janzen
Taxa with large geographic distributions generally encompass diverse macroclimatic conditions, potentially requiring local adaptation and/or phenotypic plasticity to match their phenotypes to differing environments. These eco-evolutionary processes are of particular interest in organisms with traits that are directly affected by temperature, such as embryonic development in oviparous ectotherms. Here we examine the spatial distribution of fitness-related early-life phenotypes across the range of a widespread vertebrate, the painted turtle (Chrysemys picta). We quantified embryonic and hatchling...

Data from: Na+/K+‐ATPase gene duplications in clitellate annelids are associated with freshwater colonization

Kevin M. Horn, Bronwyn W. Williams, Christer Erséus, Kenneth M. Halanych, Scott R. Santos, Michel Des Châtelliers Creuzé & Frank E. Anderson
Major habitat transitions, such as those from marine to freshwater habitats or from aquatic to terrestrial habitats, have occurred infrequently in animal evolution and may represent a barrier to diversification. Identifying genomic events associated with these transitions can help us better understand mechanisms that allow animals to cross these barriers and diversify in new habitats. Study of the Capitella telata and Helobdella robusta genomes allows examination of one such habitat transition (marine to freshwater) in...

Data from: Bees and flowers: how to feed an invasive beetle species

Jérémy Gonthier, Anna Papach, Lars Straub, Joshua W. Campbell, Geoffrey R. Williams & Peter Neumann
Invasive species may exploit a wide range of food sources, thereby fostering their success and hampering mitigation, but the actual degree of opportunism is often unknown. The small hive beetle (SHB), Aethina tumida, is a parasite of honeybee colonies endemic to sub-Saharan Africa. SHBs have now spread on all habitable continents and can also infest colonies of other social bees. To date, the possible role of solitary bee nests as alternative hosts is unknown. Similarly,...

Data from: Copepod respiration increases by 7% per degree °C increase in temperature: a meta-analysis

Kyle B. Heine, Ash Abebe, Alan E. Wilson & Wendy R. Hood
Exponential increase in respiration rate with increasing temperature in poikilotherms is well documented, however, the overall rate of change varies greatly across copepod taxa. Studies often report magnitude of change, but the rate of change in respiration across multiple temperatures is equivocal. We used 32 studies spanning 78 years of research and 50 copepod species (three orders) to quantify percent increase in respiration rates per one-unit increase in temperature. We found that copepod respiration rates...

Data from: The comparative biogeography of Philippine geckos challenges predictions from a paradigm of climate-driven vicariant diversification across an island archipelago

Jamie R Oaks, Cameron D. Siler & Rafe M. Brown
A primary goal of biogeography is to understand how large-scale environmental processes, like climate change, affect diversification. One often-invoked but seldom tested process is the so-called ''species-pump'' model, in which repeated bouts of co-speciation is driven by oscillating climate-induced habitat connectivity cycles. For example, over the past three million years, the landscape of the Philippine Islands has repeatedly coalesced and fragmented due to sea-level changes associated with the glacial cycles. This repeated climate-driven vicariance has...

Data from: Phylogenomics of Aplacophora (Mollusca, Aculifera) and a solenogaster without a foot

Kevin M. Kocot, Christiane Todt, Nina T. Mikkelsen & Kenneth M. Halanych
Recent molecular phylogenetic investigations strongly supported placement of the shell-less, worm-shaped aplacophoran molluscs (Solenogastres and Caudofoveata) and chitons (Polyplacophora) in a clade called Aculifera, which is the sister taxon of all other molluscs. Thus, understanding the evolutionary history of aculiferan molluscs is important for understanding early molluscan evolution. In particular, fundamental questions about evolutionary relationships within Aplacophora have long been unanswered. Here, we supplemented the paucity of available data with transcriptomes from 25 aculiferans and...

Data from: Neonicotinoids and ectoparasitic mites synergistically impact honeybees

Lars Straub, Geoffrey R. Williams, Beatriz Vidondo, Kitiphong Khongphinitbunjong, Gina Retschnig, Annette Schneeberger, Panuwan Chantawannakul, Vincent Dietemann & Peter Neumann
The Western honeybee, Apis mellifera, is the most important managed pollinator globally and has recently experienced unsustainably high colony losses. Synergistic interactions among stressors are believed to be primarily responsible. However, despite clear evidence of strong effect on honeybee longevity of widely-employed neonicotinoid insecticides and of the ubiquitous ectoparasitic mite Varroa destructor, no data exist to show synergistic effects between these two stressors. Even though neonicotinoids had no significant impact by themselves, we here show...

Data from: An ignored anatomical variable: pore shape shows a nonrandom variation pattern in xylem cross section

Xiping Zhao, Pingping Guo & Haixin Peng
Anatomical characteristics of vessels have a profound impact on the hydraulic conductivity of the xylem. However, pore shape, the cross-section shape of a vessel, has been ignored in previous hydraulic architecture studies. In this study, we examined whether pore shape tended to be circular, and whether this variation tendency might be affected by water flow path-length and cambial age. The circularity pores in Betula platyphylla Roth and Quercus mongolica (only earlywood) were analyzed from the...

Data from: Prior reproduction alters how mitochondria respond to an oxidative event

Wendy R. Hood, Yufeng Zhang, Halie A. Taylor, Noel R. Park, Abby E. Beatty, Ryan J. Weaver, Kang Nian Yap & Andreas N. Kavazis
An animal's pace of life is mediated by the physiological demands and stressors it experiences (e.g., reproduction) and one likely mechanism that underlies these effects is oxidative stress. Reproduction has been shown to increase or reduce oxidative stress under different conditions and modify mitochondrial performance. We hypothesized that the changes associated with reproduction can alter how animals respond to future oxidative stressors. We tested this theory by comparing the organ-specific mitochondrial response in female wild-derived...

Data from: Predicting functional responses in agro-ecosystems from animal movement data to improve management of invasive pests

Mark Wilber, Sarah Chinn, James Beasley, Raoul Boughton, Ryan Brook, Stephen Ditchkoff, Justin Fischer, Steve Hartley, Lindsey Holstrom, John Kilgo, Jesse Lewis, Ryan Miller, Nathan Snow, Kurt VerCauteren, Samantha Wisely, Colleen Webb & Kim Pepin
Functional responses describe how changing resource availability affects consumer resource use, thus providing a mechanistic approach to prediction of the invasibility and potential damage of invasive alien species (IAS). However, functional responses can be context-dependent, varying with resource characteristics and availability, consumer attributes, and environmental variables. Identifying context-dependencies can allow invasion and damage risk to be predicted across different ecoregions. Understanding how ecological factors shape the functional response in agro-ecosystems can improve predictions of hotspots...

Data from: How accurately do behavioural observations predict reproductive success in free-ranging lizards?

Mats Olsson, Tonia S. Schwartz, Erik Wapstra & Richard Shine
Behavioural ecologists often use data on patterns of male-female association to infer reproductive success of free-ranging animals. For example, a male seen with several females during the mating season is predicted to father more offspring than a male not seen with any females. We explored the putative correlation between this behaviour and actual paternity (as revealed by microsatellite data) from a long-term study on sand lizards (Lacerta agilis), including behavioural observations of 574 adult males...

Sperm morphology and count vary with fine-scale changes in local density in a wild lizard population

Matthew C Kustra, Ariel F Kahrl, Aaron M Reedy, Daniel A Warner & Robert M Cox
Given that sperm production can be costly, theory predicts that males should optimally adjust the quantity and/or quality of their sperm in response to their social environment to maximize their paternity success. Although experiments demonstrate that males can alter their ejaculates in response to manipulations of the social environment and studies show that ejaculate traits covary with social environment across populations, it is unknown whether individual variation in sperm traits corresponds to natural variation found...
