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...

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...

Dietary stress increases the total opportunity for sexual selection and modifies selection on condition-dependent traits

Silvia Cattelan, Jonathan P. Evans, Francisco Garcia-Gonzalez, Elisa Morbiato & Andrea Pilastro
Although it is often expected that adverse environmental conditions depress the expression of condition-dependent sexually-selected traits, the full consequences of environmental change for the action of sexual selection, in terms of the opportunity for total sexual selection and patterns of phenotypic selection, are unknown. Here we show that dietary stress in guppies, Poecilia reticulata, reduces the expression of several sexually-selected traits and increases the opportunity for total sexual selection (standardized variance in reproductive success) in...

Data from: It’s not all black and white: investigating colour polymorphism in manta rays across Indo-Pacific populations

Stephanie Venables, Andrea Marshall, Elitza Germanov, Robert Perryman, Ricardo Tapilatu, I. Gede Hendrawan, Anna Flam, Mike Van Keulen, Joseph Tomkins & Jason Kennington
Intraspecific colour polymorphisms have been the focus of numerous studies, yet processes affecting melanism in the marine environment remain poorly understood. Arguably the most prominent example of melanism in marine species occurs in manta rays (Mobula birostris and M. alfredi). Here, we use photo identification catalogues to document the frequency variation of melanism across Indo-Pacific manta ray populations and test for evidence of selection by predation acting on colour morph variants. We use mark-recapture modeling...

Data from: A link between heritable parasite resistance and mate choice in dung beetles

Bruno A. Buzatto, Janne S. Kotiaho, Larissa A. F. Assis & Leigh W. Simmons
Parasites play a central role in the adaptiveness of sexual reproduction. Sexual selection theory suggests a role for parasite resistance in the context of mate choice, but the evidence is mixed. The parasite-mediated sexual selection (PMSS) hypothesis derives a number of predictions, among which that resistance to parasites is heritable, and that female choice favours parasite resistance genes in males. Here we tested the PMSS hypothesis using the dung beetle Onthophagus taurus, a species that...

Data from: Effects of ovarian fluid on sperm traits and its implications for cryptic female choice in zebrafish

Federica Poli, Simone Immler & Clelia Gasparini
In polyandrous mating systems, females maintain the opportunity to bias male fertilization success after mating in a process known as cryptic female choice. Mechanisms of cryptic female choice have been described both in internal and external fertilizers, and may affect fertilization processes at different stages before, during and after fertilization. While in internal fertilizers, females have substantial control over sperm storage and fertilization, in external fertilizers, female control is limited. A key factor proposed to...

Data from: Trait convergence in photosynthetic nutrient-use efficiency along a 2-million year dune chronosequence in a global biodiversity hotspot

Caio Guilherme Pereira, Patrick E. Hayes, Odhran S. O'Sullivan, Lasantha K. Weerasinghe, Peta L. Clode, Owen K. Atkin & Hans Lambers
1. The Jurien Bay dune chronosequence in south-western Australia’s biodiversity hotspot comprises sites differing in nutrient availability, with phosphorus (P) availability declining strongly with increasing soil age. We have explored the exceptionally high photosynthetic P-use efficiency (PPUE) of Proteaceae in this region, triggering the question what the PPUE of co-occurring species in other families might be along the Jurien Bay chronosequence. 2. We explored how traits associated with PPUE, photosynthetic nitrogen (N)-use efficiency (PNUE) and...

Data from: The bold and the sperm: positive association between boldness and sperm number in the guppy

Clelia Gasparini, Elizabeth Speechley & Giovanni Polverino
Assessing the consequences of personality traits on reproductive success is one of the most important challenges in personality studies, and critical to understand the evolutionary implications of behavioural variability among animals. Personality traits are typically associated with mating acquisition in males, and, hence, linked to variation in their reproductive success. However, in most species sexual selection continues after mating, and sperm traits (such as sperm number and quality) become very important in determining post-mating competitive...

Data from: Specialized roots of Velloziaceae weather quartzite rock while mobilizing phosphorus using carboxylates

Grazielle Sales Teodoro, Hans Lambers, Diego L. Nascimento, Patrícia De Britto Costa, Denisele N. A. Flores-Borges, Anna Abrahão, Juliana L. S. Mayer, Alexandra C. H. F. Sawaya, Francisco Sérgio Bernardes Ladeira, Dalton Belchior Abdala, Carlos A. Perez & Rafael S. Oliveira
1.Campos rupestres is an extremely phosphorus (P)‐impoverished rocky ecosystem in Brazil. Velloziaceae is an important plant family in this environment, and some species colonize exposed quartzite rock. However, we know virtually nothing about their root development and nutrient acquisition within the rock outcrops and their possible role in rock weathering and landscape formation. 2.We tested the hypothesis that Velloziaceae dissolve P from the rock, enhancing rock‐weathering. The study was carried out with two Barbacenia species...

Chiarello, Jean-François Cosson, Will Cresswell, Filibus Danjuma Dami, Jens Dauber, Christopher R. Dickman, Raphael K. Didham, David P. Edwards, Fabio Z. Farneda, Yoni Gavish, Thiago Gonçalves-Souza, Demetrio Luis Guadagnin, Mickaël Henry, Adrià López-Baucells, Heike Kappes … & Yaron Ziv
Habitat destruction is the single greatest anthropogenic threat to biodiversity. Decades of research on this issue have led to the accumulation of hundreds of data sets comparing species assemblages in larger, intact, habitats to smaller, more fragmented, habitats. Despite this, little synthesis or consensus has been achieved, primarily because of non‐standardized sampling methodology and analyses of notoriously scale‐dependent response variables (i.e., species richness). To be able to compare and contrast the results of habitat fragmentation...

Data from: Nongenetic paternal effects via seminal fluid

Leigh W. Simmons & Maxine Lovegrove
Mounting evidence suggests that nongenetic paternal effects on offspring may be widespread among animal taxa, but the mechanisms underlying this form of nongenetic inheritance are not yet fully understood. Here we show that seminal fluids underlie paternal effects on early offspring survival in an insect, the cricket Teleogryllus oceanicus, and quantify the contribution of this paternal effect to the inheritance of this important fitness trait. We used castrated males within a full-sib half-sib experimental design...

Data from: Overwintering tropical herbivores accelerate detritus production on temperate reefs

Salvador Zarco-Perello & Thomas Wernberg
The tropicalization of temperate marine ecosystems can lead to increased herbivory rates, reducing the standing stock of seaweeds and potentially causing increases in detritus production. However, long-term studies analyzing these processes associated with the persistence of tropical herbivores in temperate reefs are lacking. We assessed the seasonal variation in abundances, macrophyte consumption, feeding modes and defecation rates of the range-extending tropical rabbitfish Siganus fuscescens and the temperate silver drummer Kyphosus sydneyanus and herring cale Olisthops...

Heat dissipation behaviour of birds in seasonally hot, arid-zones: are there global patterns?

Nicholas Pattinson, Michelle Thompson, Michael Griego, Grace Russell, Nicola Mitchell, Rowan Martin, Blair Wolf, Ben Smit, Susan Cunningham & Andrew McKechnie
Quantifying organismal sensitivity to heat stress provides one means for predicting vulnerability to climate change. Birds are ideal for investigating this approach, as they display quantifiable fitness consequences associated with behavioural and physiological responses to heat stress. We used a recently developed method that examines correlations between readily-observable behaviours and air temperature (Tair) to investigate interspecific variation in avian responses to heat stress in seasonally hot, arid regions on three continents: the southwestern United States,...

Data from: Phylogenomic resolution of the cetacean tree of life using target sequence capture

Michael McGowen, Georgia Tsagkogeorga, Sandra Álvarez-Carretero, Mario Dos Reis, Monika Struebig, Rob Deaville, Paul Jepson, Simon Jarman, Andrea Polanowski, Phillip Morin & Stephen Rossiter
The evolution of the cetaceans, from their early transition to an aquatic lifestyle to their subsequent diversification, has been the subject of numerous studies. However, while the higher-level relationships among cetacean families have been largely settled, several aspects of the systematics within these groups remain unresolved. Problematic clades include the oceanic dolphins (37 spp.), which have experienced a recent rapid radiation, and the beaked whales (22 spp.), which have not been investigated in detail using...

Data from: Male responses to sperm competition risk when rivals vary in their number and familiarity

Samuel J. Lymbery, Joseph L. Tomkins & Leigh W. Simmons
Males of many species adjust their reproductive investment to the number of rivals present simultaneously. However, few studies have investigated whether males sum previous encounters with rivals, and the total level of competition has never been explicitly separated from social familiarity. Social familiarity can be an important component of kin recognition and has been suggested as a cue that males use to avoid harming females when competing with relatives. Previous work has succeeded in independently...

Data from: Evaluating the genetic architecture of quantitative traits via selection followed by inbreeding

Robert J. Dugand, W. Jason Kennington & Joseph L. Tomkins
The deleterious mutation model proposes that quantitative trait variation should be dominated by rare, partially recessive, deleterious mutations. Following artificial selection on a focal trait, the ratio of the difference in inbreeding effects between control and selected populations (ΔB), to the difference in trait means caused by directional selection (ΔM), can inform the extent to which deleterious mutations cause quantitative trait variation. Here, we apply the ΔB/ΔM ratio test to two quantitative traits (male mating...

Data from: Natural and sexual selection on cuticular hydrocarbons: a quantitative genetic analysis

Jacob D. Berson, Marlene Zuk & Leigh W. Simmons
While the reproductive benefits of sexual displays have been widely studied, we have relatively limited evidence of the fitness costs associated with most display traits. Insect cuticular hydrocarbon (CHC) profiles are sexually selected traits that also protect against desiccation. These two functions are thought to oppose each other, with investment in particular compounds believed to increase attractiveness at the expense of compounds that protect against water-loss. We investigated this potential trade-off in a quantitative genetic...

Data from: Predicting future distributions of lanternfish; a significant ecological resource within the Southern Ocean

Jennifer J. Freer, Geraint A. Tarling, Martin A. Collins, Julian C. Partridge & Martin J. Genner
Aim: Lanternfish (Myctophidae) are one of the most abundant and ecologically important families of pelagic teleosts, yet how these species will respond to climate change is unclear, especially within polar regions. The aim of this study is to predict the impact of climate change on the distribution of Southern Ocean lanternfish, and to relate these predicted responses to species traits. Location: Circumpolar, 35-75° S. Methods: We used MaxEnt ecological niche models to estimate the present...

Data from: Sex-specific pace-of-life syndromes

Joe A. Moschilla, Joseph L. Tomkins & Leigh W. Simmons
The pace-of-life syndrome (POLS) hypothesis considers an animal’s behavior, physiology, and life-history as non-independent components of a single integrated phenotype. However, frequent deviations from the expected correlations between POLS traits suggests that these relationships may be context, and potentially, sex-dependent. To determine whether the sexes express distinct POLS trait covariance structures, we observed the behavior (mobility, latency to emerge from a shelter), physiology (mass-specific metabolic rate) and life-history (lifespan, development time) of male and female...

Data from: Primary pollinator exclusion has divergent consequences for pollen dispersal and mating in different populations of a bird-pollinated tree

Nicole Bezemer
Pollination by nectarivorous birds is predicted to result in different patterns of pollen dispersal and plant mating compared to pollination by insects. We tested the prediction that paternal diversity, outcrossing rate and realised pollen dispersal will be reduced when the primary pollinator group is excluded from bird-pollinated plants. Pollinator exclusion experiments in conjunction with paternity analysis of progeny were applied to Eucalyptus caesia Benth. (Myrtaceae), a predominantly honeyeater-pollinated tree that is visited by native insects...

Data from: Dispersal, philopatry and population genetic structure of the mainland dibbler, Parantechinus apicalis

Rujiporn Thavornkanlapachai, W. Jason Kennington, Kym Ottewell, J. Anthony Friend & Harriet R. Mills
Dispersal plays an important role in the population structure and resilience of species. To gain a better understanding of dispersal in the endangered Australian marsupial, the dibbler (Parantechinus apicalis), we screened 199 individuals from seven locations within the Fitzgerald River National Park, Western Australia, for genetic variation at 17 microsatellite loci. There were high levels of genetic variation within all sites (gene diversity ranged from 0.68 to 0.71) as well as significant genetic differentiation between...

Data from: Marine environmental DNA biomonitoring reveals seasonal patterns in biodiversity and identifies ecosystem responses to anomalous climatic events

Tina E. Berry, Benjamin J. Saunders, Megan L. Coghlan, Michael Stat, Simon Jarman, Anthony J. Richardson, Claire H. Davies, Oliver Berry, Euan S. Harvey & Michael Bunce
Marine ecosystems are changing rapidly as the oceans warm and become more acidic. The physical factors and the changes to ocean chemistry that they drive can all be measured with great precision. Changes in the biological composition of communities in different ocean regions are far more challenging to measure because most biological monitoring methods focus on a limited taxonomic or size range. Environmental DNA (eDNA) analysis has the potential to solve this problem in biological...

Data from: Experimental evolution reveals divergence in female genital teeth morphology in response to sexual conflict intensity in a moth

Kathryn B. McNamara, Liam R. Dougherty, Nina Wedell & Leigh W. Simmons
The rapid evolutionary divergence of male genital structures under sexual selection is well documented. However, variation in female genital traits and the potential for sexual conflict to drive the coevolution between male and female traits has only recently received attention. In many lepidopterans females possess genital teeth (collectively, signa). Comparative studies suggest these teeth, involved in the deflation of spermatophores, may have coevolved with male spermatophore thickness via sexually antagonistic coevolution in a contest over...

Data from: A review of protocols for the experimental release of kelp (Laminariales) zoospores

Nahlah Alsuwayian, Margaret Mohring, Marion Cambridge, Melinda Coleman, Gary Kendrick & Thomas Wernberg
Kelps (order Laminariales) are foundation species in temperate and arctic seas globally, but they are in decline in many places. Laminarian kelp have an alternation of generations and this poses challenges for experimental studies due to the difficulties in achieving zoospore release and gametophyte growth. Here we review and synthesize the protocols that have been used to induce zoospore release in kelps to identify commonalities and provide guidance on best practices. We found 171 papers,...
