Research on the behavioral responses of animals to extreme weather events, such as heatwaves, is lacking even though their frequency and intensity in nature are increasing. Here, we investigated the behavioral response to a simulated heatwave in two species of antlions (Neuroptera: Myrmeleontidae). These insects spend the majority of their lives as larvae and live in sandy areas suitable for a trap-building hunting strategy. We used larvae of Myrmeleon bore and Euroleon nostras, which are...
Needle traits of coniferous forests reflect environmental conditions and influence tree physiology and growth. Given the sensitivity of needle traits and tree growth to climate, temperature warming of ≈1°C in the past century may have influenced structure and function of high latitude forests across the globe. Here we show that throughout a ≈1,000 km transect in cold, high latitude Scots pine (Pinus sylvestris L.) forests in Sweden, which has warmed by ≈1°C in a century,...
High variation in last male sperm precedence and genital morphology in the emerald damselfly Lestes sponsaFrank Johansson, David Berger, Jacob Höglund, Yvonne Meyer-Lucht, Patrik Rödin-Mörch, Szymon Sniegula & Phillip Watts
In organisms where individuals mate multiply, knowledge on the proportion of offspring sired by the last male to mate (P2) under field conditions is important for a thorough understanding of how sexual selection works in nature. In many insect groups, pronounced intraspecific variation in P2 is commonplace. Interestingly, however, in stark contrast to these observations, compilation of P2 data in dragonflies and damselflies (Odonata) indicate that a high P2, seldom below 0.95, is a feature...
Data from: Impact of brood parasitism and predation on nest survival of the fan-tailed gerygone in New CaledoniaAlfredo Attisano, Lara B. Groß, Nozomu J. Sato, Yuji Okahisa, Keita D. Tanaka, Roman Gula, Keisuke Ueda & Jörn Theuerkauf
Predation and brood parasitism are common reasons for nesting failure in passerine species and the additive impact by invasive species is a major conservation concern, particularly on tropical islands. Recognising the relative contribution of the different components of nesting failure rates is important to understand co-evolutionary interactions within brood parasite-host systems. In the remote archipelago of New Caledonia, the fan-tailed gerygone Gerygone flavolateralis is the exclusive host of the brood-parasitic shining bronze-cuckoo Chalcites lucidus. Additionally,...
1. Despite large conservation efforts to halt the loss of farmland biodiversity in Europe, negative population trends are still observed, especially for common species. Old villages and human settlements are biodiversity hotspots and important breeding habitats for farmland birds, but recent requirements for energy saving measures and improved living comfort have changed their architecture and habitats. Consequently, modernisation of villages may negatively affect bird diversity due to the loss of nesting and foraging sites. 2....
This dataset derives from cross-over experiments using ant worker rescue behaviour towards caterpillars of the socially parasitic butterfly from two host-ecotypes. The data comprise datasets collected from four 4 experiments 3 hours after testing and from 4 experiments 7 days later. They all include nest numbers, the order of retrieval ranked by the attention of nurse ants to the ant pupae, large larvae and small larvae and the adult Maculinea rebeli. The data give the...
Data from: Beech roots are simultaneously colonized by multiple genets of the ectomycorrhizal fungus Laccaria amethystina clustered in two genetic groupsSara Hortal, Lidia K. Trocha, Claude Murat, Igor J. Chybicki, Marc Buée, Magdalena Trojankiewicz, Jaroslaw Burczyk & Francis Martin
In this study we characterize and compare the genetic structure of aboveground and belowground populations of the ectomycorrhizal fungus Laccaria amethystina in an unmanaged mixed beech forest. Fruiting bodies and mycorrhizas of L. amethystina were mapped and collected in four plots in the Świętokrzyskie Mountains (Poland). A total of 563 fruiting bodies and 394 mycorrhizas were successfully genotyped using the rDNA IGS1 (intergenic spacer) and seven SSR (simple sequence repeat) markers. We identified two different...
Targeted capture coupled with high throughput sequencing can be used to gain information about nuclear sequence variation at hundreds to thousands of loci. Divergent reference capture makes use of molecular data of one species to enrich target loci in other (related) species. This is particularly valuable for non-model organisms, for which often no a priori knowledge exists regarding these loci. Here, we have used targeted capture to obtain data for 809 nuclear coding DNA sequences...
Brood sex ratio, early chick survival, and cell-mediated immunity measurements for 3 experimental groups of Larus canus and Chroicocephalus ridibundus pairsDariusz Bukaciński, Monika Bukacińska & Przemysław Chylarecki
Sex allocation theory predicts that parents should adjust their brood sex ratio to maximize fitness returns in relation to parental investment. Adaptive adjustment of sex ratio may be driven by differential costs of rearing sons and daughters or differential benefits of investing limited resources into offspring of different sex. In both cases, possible sex ratio bias should depend on parental condition. For sexually dimorphic birds with males larger than females, sons may be less likely...
Small mammals impact plant recruitment globally via size-dependent seed predation, generating a unimodal pattern across ecosystems. Chen et al. (2021) critiqued our seed removal analysis, advocating corrections for exposure time. We show in our rebuttal that such manipulations are unwarranted and argue for increased emphasis on plant recruitment metrics. This archive holds the updated seed removal dataset used for our rebuttal.
Anatomy of the nasal and auditory regions of the fossil lagomorph Palaeolagus haydeni: systematic and evolutionary implicationsŁucja Fostowicz-Frelik, Irina Ruf & Jin Meng
Palaeolagus, a late Eocene to early Miocene North American lagomorph genus, represented by numerous and well-preserved specimens, has been long considered a basal leporid, although it is currently understood as a stem lagomorph. Based on micro-computed tomography (μCT) data and 3D reconstructions, here we present the first description of intracranial structures of the nasal and auditory regions of a complete skull of Palaeolagus haydeni from the early Oligocene of Nebraska. Although Palaeolagus haydeni shows a...
Uncertainties surrounding tree carbon allocation to growth are a major limitation to projections of forest carbon sequestration and response to climate change. The prevalence and extent to which carbon assimilation (source) or cambial activity (sink) mediate wood production are fundamentally important and remain elusive. We quantified source-sink relations across biomes by combining eddy-covariance gross primary production with extensive on-site and regional tree ring observations. We found widespread temporal decoupling between carbon assimilation and tree growth,...
Breeding in the pandemic: Short-term lockdown restrictions in a European capital city did not alter the life-history traits of two urban adaptersMichela Corsini, Zuzanna Jagiello, Michał Walesiak, Michał Redlisiak, Ignacy Stadnicki, Ewa Mierzejewska & Marta Szulkin
Humans are transforming natural habitats into managed urban green areas and impervious surfaces with unprecedented peace. Yet, the effects of human presence per se on animal life-history traits are rarely tested. This is particularly true in cities, where human presence is often indissociable from urbanisation itself. We analysed four years of avian breeding data collected in a European capital city to test whether lockdown measures altered nestbox occupancy and life-history traits in terms of egg-laying...
