Anatomical studies of leaflets of species from the plant subfamily Tribuloideae (Zygophyllaceae)

Maximilian Lauterbach & Gudrun Kadereit
Leaflets of 26 accessions of species from subfamily Tribuloideae (Zygophyllaceae), using herbarium material, were sectioned after chemical fixation and embedding. For each section, the area of the mesophyll (M) tissue, bundle sheath (BS) tissue, and vascular tissue were measured, as well as the BS area, BS distance, and interveinal distance. The ratio of BS to M areas was also calculated. With a molecular phylogeny as a guide, these leaf anatomical traits, which are typically altered...

Identification of seminal proteins related to the inhibition of mate searching in female crickets

Joe Moschilla
In response to the reduction in fitness associated with sperm competition, males are expected to evolve tactics that hinder female remating. For example, females often display a post-mating reduction in their sexual receptivity that has been shown to be mediated by proteins contained in a male’s seminal fluid (sfps). However, although there has been comprehensive research on sfps in genetically well characterized species, few non-model species have been studied in such detail. We initially confirm...

Data from: Predicting ecological responses in a changing ocean: the effects of future climate uncertainty

Jennifer J. Freer, Julian C. Partridge, Geraint A. Tarling, Martin A. Collins & Martin J. Genner
Predicting how species will respond to climate change is a growing field in marine ecology, yet knowledge of how to incorporate the uncertainty from future climate data into these predictions remains a significant challenge. To help overcome it, this review separates climate uncertainty into its three components (scenario uncertainty, model uncertainty, and internal model variability) and identifies four criteria that constitute a thorough interpretation of an ecological response to climate change in relation to these...

Data from: Estimating relatedness and inbreeding using molecular markers and pedigrees: the effect of demographic history

Stephen P. Robinson, Leigh W. Simmons & W. Jason Kennington
Estimates of inbreeding and relatedness are commonly calculated using molecular markers, although the accuracy of such estimates has been questioned. As a further complication, in many situations, such estimates are required in populations with reduced genetic diversity, which is likely to affect their accuracy. We investigated the correlation between microsatellite- and pedigree-based coefficients of inbreeding and relatedness in laboratory populations of Drosophila melanogaster that had passed through bottlenecks to manipulate their genetic diversity. We also...

Data from: Arthropod distribution in a tropical rainforest: tackling a four dimensional puzzle

Yves Basset, Lukas Cizek, Philippe Cuénoud, Raphael K. Didham, Vojtech Novotny, Frode Ødegaard, Tomas Roslin, Alexey K. Tishechkin, Jürgen Schmidl, Neville N. Winchester, David W. Roubik, Henri-Pierre Aberlenc, Johannes Bail, Héctor Barrios, Jonathan R. Bridle, Gabriela Castaño-Meneses, Bruno Corbara, Gianfranco Curletti, Wesley Duarte Da Rocha, Domir De Bakker, Jacques H.C. Delabie, Alain Dejean, Laura L. Fagan, Andreas Floren, Roger L. Kitching … & Jacques H. C. Delabie
Quantifying the spatio-temporal distribution of arthropods in tropical rainforests represents a first step towards scrutinizing the global distribution of biodiversity on Earth. To date most studies have focused on narrow taxonomic groups or lack a design that allows partitioning of the components of diversity. Here, we consider an exceptionally large dataset (113,952 individuals representing 5,858 species), obtained from the San Lorenzo forest in Panama, where the phylogenetic breadth of arthropod taxa was surveyed using 14...

Data from: Effectiveness of camera traps for quantifying daytime and nighttime visitation by vertebrate pollinators

Siegfried L. Krauss, David G. Roberts, Ryan D. Phillips & Caroline Edwards
1. Identification of pollen vectors is a fundamental objective of pollination biology. The foraging and social behavior of these pollinators has profound effects on plant mating, making quantification of their behaviour critical for understanding the ecological and evolutionary consequences of different pollinators for the plants they visit. However, accurate quantification of visitation may be problematic, especially for shy animals and/or when the temporal and spatial scale of observation desired is large. Sophisticated heat- and movement-triggered...

Data from: Long-term data suggest jarrah-forest establishment at restored mine sites is resistant to climate variability

Rachel J. Standish, Matthew I. Daws, Aaron D. Gove, Raphael K. Didham, Andrew H. Grigg, John M. Koch & Richard J. Hobbs
1. Global climate change is projected to increase the frequency and intensity of drought in dry regions due to warming temperatures and declining rainfall. Severe drought can trigger tree mortality and drive persistent vegetation change. 2. To date, most empirical studies have focused on drought-induced mortality of adult trees, but this needs to be matched by similar efforts to understand drought impacts on seedling establishment if we are to understand the resilience of the world's...

Data from: Going to extremes for sodium acquisition: use of community land and high-altitude areas by mountain gorillas Gorilla beringei in Rwanda

Cyril C. Grueter, Edward Wright, Didier Abavandimwe, Sylvia Ortmann, Antoine Mudakikwa, Abel Musana, Propser Uwingeli, Felix Ndagijimana, Veronica Vecellio, Tara S. Stoinski & Martha M. Robbins
Space use in mammals may be influenced not only by their primary foods, but also by localized sources of physiologically critical resources such as sodium-rich plants. We examined how sodium acquisition influences habitat use in mountain gorillas (Gorilla beringei) in Rwanda which have increased the amount of time they forage on community land outside of Volcanoes National Park (VNP), where eucalyptus (Eucalyptus spp.) tree bark is their most frequently eaten food. We measured sodium content...

Data from: Mixed evidence for the erosion of inter-tactical genetic correlations through intralocus tactical conflict

Kyana N. Pike, Joseph L. Tomkins & Bruno A. Buzatto
Alternative reproductive tactics, whereby members of the same sex use different tactics to secure matings are often associated with conditional intrasexual dimorphisms. Given the different selective pressures on males adopting each mating tactic,, intrasexual dimorphism is more likely to arise if phenotypes are genetically uncoupled and free to evolve towards their phenotypic optima. However, in this context, genetic correlations between male morphs could result in intralocus tactical conflict. We investigated the genetic architecture of male...

Data from: Deep phylogeographic structuring of populations of the trapdoor spider Moggridgea tingle (Migidae) from southwestern Australia: evidence for long-term refugia within refugia

Steven J.B. Cooper, Mark S. Harvey, Kathleen M. Saint & Barbara Y. Main
Southwestern Australia has been recognized as a biodiversity hotspot of global significance, and it is particularly well known for its considerable diversity of flowering plant species. Questions of interest are how this region became so diverse and whether its fauna show similarly diverse patterns of speciation. Here we have carried out a phylogeographic study of trapdoor spiders (Migidae: Moggridgea), a presumed Gondwanan lineage found in wet forest localities across southwestern Australia. Phylogenetic, molecular clock and...

Data from: Regime shifts shorten food chains for mesopredators with potential sublethal effects

Tessa N. Hempson, Nicholas A.J. Graham, Aaron M. MacNeil, Nathalie Bodin, Shaun K. Wilson & Nicholas A. J. Graham
1. Predator populations are in decline globally. Exploitation, as well as habitat degradation and associated changes in prey availability are key drivers of this process of trophic downgrading. In the short term, longevity and dietary adaptability of large-bodied consumers can mask potential sub-lethal effects of a changing prey base, producing a delayed effect that may be difficult to detect. 2. In coral reef ecosystems, regime shifts from coral- to algae-dominated states caused by coral bleaching...

Data from: Macronutrients and micronutrients drive trade-offs between male pre- and post-mating sexual traits

Soon Hwee Ng, Stephen J. Simpson & Leigh W. Simmons
Nutrition fundamentally affects growth and reproduction, and identifying how nutrient intakes are linked to the expression of these life-history traits can advance understanding of the mechanisms underlying life history trade-offs. Males are thought to face trade-offs between the allocation of resources to pre-mating secondary sexual traits for gaining access to females and allocation to post-mating traits such as ejaculate quality that affects their fertility. We used the Geometric Framework for nutrition to examine the effects...

Data from: Males evolve to be more harmful under increased sexual conflict intensity in a seed beetle

Kathryn McNamara, Nadia Sloan, Sian Kershaw, Emile Van Lieshout & Leigh Simmons
One conspicuous manifestation of sexual conflict is traumatic mating, in which male genitalia damage the female during copulation. The penis of the seed beetle, Callosobruchus maculatus, is covered in spines that damage the female reproductive tract. Females kick males ostensibly to shorten these harmful copulations. How these iconic conflict behaviours coevolve in response to sexual conflict intensity can provide insight into the economics of these traits. We examined whether male harm and female resistance coevolved...

Vellozioid roots allow for habitat specialisation among rock- and soil-dwelling Velloziaceae in campos rupestres

Anna Abrahão, Patrícia De Britto Costa, Grazielle Sales Teodoro, Hans Lambers, Diego L. Nascimento, Sara A. L. De Andrade, Megan H. Ryan & Rafael S. Oliveira
1. Plant growth on harsh substrates (habitat specialisation) requires specific traits to cope with stressful conditions. 2. We tested whether traits related to nutrient acquisition (root colonisation by fungal symbionts, and plant morphological and physiological specialisations), and nutrient use (leaf nitrogen (N) and phosphorus (P) concentrations and N- and P-remobilisation efficiency), were related to habitat specialisation for 27 species of Velloziaceae growing either in soil or on rocks in extremely P-impoverished campos rupestres habitats. If...

Xylomelum occidentale (Proteaceae) accesses relatively mobile soil organic phosphorus without releasing carboxylates

Hongtao Zhong, Jun Zhou, Azrul Azmi, André Arruda, Ashlea Doolette, Ronald Smernik & Hans Lambers
1. Hundreds of Proteaceae species in Australia and South Africa typically grow on phosphorus (P)-impoverished soils, exhibiting a carboxylate-releasing P-mobilising strategy. In the Southwest Australian Biodiversity Hotspot, two Xylomelum (Proteaceae) species are widely distributed, but restricted within that distribution. 2. We grew X. occidentale in hydroponics at 1 μM P. Leaves, seeds, rhizosheath and bulk soil were collected in natural habitats. 3. Xylomelum occidentale did not produce functional cluster roots and occupied soils that are...

Acoustic coordination by allied male dolphins in a cooperative context

Bronte Moore, Richard Connor, Simon Allen, Michael Krützen & Stephanie King
Synchronous displays are hallmarks of many animal societies, ranging from the pulsing flashes of fireflies, to military marching in humans. Such displays are known to facilitate mate attraction or signal relationship quality. Across many taxa, synchronous male displays appear to be driven by competition, while synchronous displays in humans are thought to be unique in that they serve a cooperative function. Indeed, it is well established that human synchrony promotes cooperative endeavours and increases success...

Egg-induced changes to sperm phenotypes shape patterns of multivariate selection on ejaculates

Jessica Hadlow, Jonathan Evans & Rowan Lymbery
Ejaculates exhibit extraordinary phenotypic diversity and rapid rates of evolution, yet the adaptive value of most sperm traits remains equivocal. Recent findings suggest that to understand how selection targets ejaculates we must recognize that female-imposed physiological conditions often alter ejaculate phenotypes. These phenotypic changes to ejaculates may influence the relationships among sperm traits and their association with fitness. Here, we show that chemical substances released by eggs (known to modify sperm physiology and behavior) alter...

Data from: Fate of internal waves on a shallow shelf

Kristen Davis, Robert Arthur, Emma Reid, Thomas DeCarlo, Anne Cohen, Oliver Fringer & Justin Rogers
Internal waves strongly influence the physical and chemical environment of coastal ecosystems worldwide. We report novel observations from a distributed temperature sensing (DTS) system that tracked the transformation of internal waves from the shelf break to the surf zone over a narrow shelf-slope region in the South China Sea. The spatially-continuous view of temperature fields provides a perspective of physical processes commonly available only in laboratory settings or numerical models, including internal wave reflection off...
