Relative influence of predators, competitors, and seascape heterogeneity on behaviour and abundance of coral reef mesopredators

Emily Lester
Determining influences of predation and competition on community dynamics is particularly challenging in coral reef systems where interspecific interactions between many predator and prey species play out in patchy landscapes. We used ~1000 stereo-Baited Remote Underwater Video deployments (Stereo-BRUVs) to assess the relative abundance and analysed the behaviour of two size classes of mesopredatory teleosts (lutajnids, serranids, lethrinids) in the presence and absence of larger predators (mesopredatory and apex carcharhinids). For mesopredatory teleosts, the presence...

Spoiled for choice: Number of signalers constrains mate choice based on acoustic signals

Jessie Tanner
In many taxa, receivers use signals to detect and discriminate among mates. Signal detection and discrimination thus has important fitness consequences for individuals. Noise is defined as any factor that prevents detection or discrimination of signals. The noise produced by groups of signaling animals is a well-known impediment to signal detection and discrimination in animals, but how many signals produce the emergent, masking effects of noise? This dataset was generated to explore how receivers discriminate...

Subcellular view of host–microbiome nutrient exchange in sponges: insights into the ecological success of an early metazoan–microbe symbiosis

Meggie Hudspith, Laura Rix, Michelle Achlatis, Jeremy Bougoure, Paul Guagliardo, Peta L. Clode, Nicole S. Webster, Gerard Muyzer, Mathieu Pernice & Jasper M. De Goeij
Background: Sponges are increasingly recognised as key ecosystem engineers in many aquatic habitats. They play an important role in nutrient cycling due to their unrivalled capacity for processing both dissolved and particulate organic matter (DOM and POM) and the exceptional metabolic repertoire of their diverse and abundant microbial communities. Functional studies determining the role of host and microbiome in organic nutrient uptake and exchange, however, are limited. Therefore, we coupled pulse-chase isotopic tracer techniques with...

Data from: Genotype-environment mismatch of kelp forests under climate change

Sofie Vranken, Thomas Wernberg, Armin Scheben, Anita Severn-Ellis, Jacqueline Batley, Philipp Emanuel Bayer, David Edwards, David Wheeler & Melinda Ann Coleman
Climate change is increasingly impacting ecosystems globally. Understanding adaptive genetic diversity and whether it will keep pace with projected climatic change is necessary to assess species’ vulnerability and design efficient mitigation strategies such as assisted adaptation. Kelp forests are the foundations of temperate reefs globally but are declining in many regions due to climate stress. A lack of knowledge of kelps’ adaptive genetic diversity hinders assessment of vulnerability under extant and future climates. Using 4245...

Interactions between belowground traits and rhizosheath fungal and bacterial communities for phosphorus acquisition

Nicolas Honvault, David Houben, Stéphane Firmin, Hacene Maglouli, Frédéric Laruelle, Joël Fontaine, Anissa Lounes, Arnaud Coutu, Hans Lambers & Michel-Pierre Faucon
1. Plant-soil microbes interactions play a central role in plant nutrient acquisition and thus ecosystem functioning and nutrient availability in agroecosystems. Adjustments in root morphology, root exudation and associations with microorganisms such as arbuscular mychorrizal fungi are common for phosphorus acquisition. Yet how plant belowground functional traits interact with microbial communities for P-acquisition remains largely unknown, limiting our understanding of phosphorus availability in agroecosystems. 2. Interactions between belowground functional traits and rhizosheath soil microbial communities...

Data from: Increase in leaf organic acids to enhance adaptability of dominant plant species in karst habitats

Songbo Tang, Jian-Feng Liu, Hans Lambers, Lingling Zhang, Zhanfeng Liu, Yutong Lin & Yuanwen Kuang
Estimation of leaf nutrient composition of dominant plant species from contrasting habitats (i.e. karst and non-karst forests) provides an opportunity to understand how plants are adapted to karst habitats from the perspective of leaf traits. Here, we measured leaf traits – specific leaf area (SLA), concentrations of total carbon ([TC]), nitrogen ([TN]), phosphorus ([TP]), calcium ([Ca]), magnesium ([Mg]), manganese ([Mn]), minerals ([Min]), soluble sugars, soluble phenolics, lipids, and organic acids ([OA]) – and calculated water–use...

Survival and malformations, swimming performance and tadpole traits

Jonathan Evans, Nicola Mitchell & Tabitha Rudin-Bitterli
Targeted gene flow (TGF) could bolster the adaptive potential of isolated populations threatened by climate change, but could also lead to outbreeding depression. Here, we explore these possibilities by creating mixed- and within-population crosses in a terrestrial-breeding frog species threatened by a drying climate. We reared embryos on wet and dry soils and quantified fitness-related traits upon hatching. TGF produced mixed outcomes in hybrids which depended on crossing direction (origin of gametes from each sex)....

Observational foraging behaviour of avian pollinators in restored and remnant Banksia woodlands

Alison Ritchie, Carole Elliott, Elizabeth Sinclair & Siegfried Krauss
Pollinators, and the pollination services they provide, are critical for seed set and self-sustainability of most flowering plants. Despite this, pollinators are rarely assessed in restored plant communities, where their services are largely assumed to re-establish. This data set contains the bird-pollinator richness, foraging and bird interaction behaviour between natural and restored Banksia woodland sites in Western Australia. These parameters were measured for natural communities of varying size and degree of fragmentation, and restored plant...

Condition dependent seminal fluid gene expression and intergenerational paternal effects on ejaculate quality

Leigh W Simmons, Soon Hwee Ng & Maxine Lovegrove
1. There is increasing evidence to show that the environment experienced by fathers can have intergenerational paternal effects on the phenotype of offspring. Paternal effects can be mediated by ejaculate traits beyond the genes carried by sperm, for example through methylation of DNA during spermatogenesis, or non-sperm components of the ejaculate such as small RNAs or seminal fluid proteins (sfp). 2. Theory suggests that ejaculate-mediated paternal effects can have important evolutionary consequences, especially if they...

The effect of baculum shape and mating behaviour on mating-induced Prolactin release in female house mice

Gonçalo I. André, Renee Firman & Leigh Simmons
Male genitalia are subject to rapid divergent evolution, and sexual selection is believed to be responsible for this pattern of evolutionary divergence. Genital stimulation during copulation is an essential feature of sexual reproduction. In mammals, the male intromittent genitalia induces a cascade of physiological and neurological changes in females that promote pregnancy. Previous studies of the house mouse have shown that the shape of the baculum (penis bone) influences male reproductive success and responds to...

Persistence of tropical herbivores in temperate reefs constrain kelp resilience to cryptic habitats

Salvador Zarco-Perello, Nestor Bosch & Thomas Wernberg
1. Global warming is facilitating the range-expansion of tropical herbivores, causing a tropicalization of temperate marine ecosystems, where tropical herbivores can suppress habitat-forming macrophytes, supporting the resilience of canopy-free ecosystem states. However, currently we lack a thorough understanding of the mechanisms that, on one hand, support the persistence of tropical herbivores and on the other support the recovery of temperate foundation species in tropicalized ecosystems, a required knowledge to predict potential regime-shifts and reversals to...

The chicken pan-genome reveals gene content variation and a promoter region deletion in IGF2BP1 affecting body size

Kejun Wang, Haifei Hu, Yadong Tian, Jingyi Li, Armin Scheben, Chenxi Zhang, Yiyi Li, Junfeng Wu, Lan Yang, Xuewei Fan, Guirong Sun, Donghua Li, Yanhua Zhang, Ruili Han, Ruirui Jiang, Hetian Huang, Fengbin Yan, Yanbin Wang, Zhuanjian Li, Guoxi Li, Xiaojun Liu, Wenting Li, David Edwards & Xiangtao Kang
Domestication and breeding have reshaped the genomic architecture of chicken, but the retention and loss of genomic elements during these evolutionary processes remain unclear. We present the first chicken pan-genome constructed using 664 individuals, which identified an additional ∼66.5 Mb sequences that are absent from the reference genome (GRCg6a). The constructed pan-genome encoded 20,491 predicated protein-coding genes, of which higher expression level are observed in conserved genes relative to dispensable genes. Presence/absence variation (PAV) analyses...

Character set and phylogenetic analyses of the living and fossil egerniine scincids of Australia

Kailah Thorn, Mark Hutchinson, Michael Lee, Aaron Camens & Trevor Worthy
The diverse living Australian lizard fauna contrasts greatly with their limited Oligo-Miocene fossil record. New Oligo-Miocene fossil vertebrates from the Namba Formation (south of Lake Frome, South Australia) were uncovered from multiple expeditions from 2007–2018. Abundant disarticulated material of small vertebrates was concentrated in shallow lenses along the palaeo-lake edges, now exposed on the western shore. The fossiliferous lens occurring within the Namba Formation, also known from Billeroo Creek 2 km northeast of Lake Pinpa,...

Nongenetic inheritance of behavioural variability

Joe Moschilla
1. Environmentally-mediated nongenetic inheritance extends the concept of phenotypic plasticity across generations, allowing for the experience of parents to influence the physiology, life-history and behaviour of their offspring. 2. We assess whether the perceived social environment of mothers and fathers impacts offspring behaviour in the Australian field cricket (Teleogryllus oceanicus). 3. We varied parents’ perception of the density of conspecific males by exposing parents to either the presence or absence of male song throughout rearing....

The role of extreme rain events in driving tree growth across a continental-scale climatic range in Australia

Alison O'Donnell, Michael Renton, Kathryn Allen & Pauline Grierson
Rainfall regimes in many parts of the world have become increasingly dominated by fewer, but more extreme, rainfall events. Understanding how tree growth responds to changes in the frequency and intensity of rain events is critical to predicting how climate change will impact on forests and woodlands in the future. In this study, we used five tree-ring records of the native Australian conifer Callitris columellaris that span a large (> 20 degree) latitudinal and climatic...

The thermal environment of sperm affects offspring success: a test of the anticipatory paternal effects hypothesis in a broadcast spawner

Rowan Lymbery, Jason Kennington & Jonathan Evans
There has been an explosion of recent evidence that environments experienced by fathers or their ejaculates can influence offspring phenotypes (paternal effects). However, little is known about whether such effects are adaptive, which would have far-reaching implications for the many species facing rapidly changing environments. For example, some arguments suggest paternal effects might be a source of cross-generational plasticity, preparing offspring to face similar conditions to their father (anticipatory hypothesis). Alternatively, ejaculate-mediated effects on offspring...

Marine ecoregions and subecoregions within Indo-West Australian waters: A statistical approach based on species distributions

Hadiyanto Hadiyanto, Renae Hovey, Christopher Glasby & Jane Prince
Aim: The Marine Ecoregions of the World (MEOW) system delineates the oceans into 232 ecoregions. Here, we aimed to evaluate the suitability of this system to represent species distributions within Indo-West Australian waters, explore alternative ecoregions and new subecoregions, and investigate environmental variables that are correlated with species distributions within those waters. Location: Indo-West Australia Taxa: Vertebrates, invertebrates, marine plants Methods: We downloaded occurrence data for 14,513 marine species from the Ocean Biogeographic Information System....

Disentangling biotic and abiotic drivers of intraspecific trait variation in woody plant seedlings at forest edges

Shilu Zheng, Bruce Webber, Raphael Didham, Chun Chen, Mingjian Yu, Bruce L. Webber & Raphael K. Didham
In fragmented forests, edge effects can drive intraspecific variation in seedling performance that influences forest regeneration and plant composition. However, few studies have attempted to disentangle the relative biotic and abiotic drivers of intraspecific variation in seedling performance. In this study, we carried out a seedling transplant experiment with a factorial experimental design on three land-bridge islands in the Thousand Island Lake, China, using four common native woody plant species. At different distances from the...
