Plant diversity is an important driver of diversity at other trophic levels, suggesting that cascading extinctions could reduce overall biodiversity. Most evidence for positive effects of plant diversity comes from grasslands. Despite the fact that forests are hotspots of biodiversity, the importance of tree diversity, in particular its relative importance compared to other management related factors, in affecting forest‐associated taxa is not well known. To address this, we used data from 183 plots, located in...
Data from: Fine-scale appendage structure of the Cambrian trilobitomorph Naraoia spinosa and its ontogenetic and ecological implicationsDayou Zhai, Gregory Edgecombe, Andrew Bond, Huijuan Mai, Xianguang Hou & Yu Liu
Trilobitomorphs are a species-rich Palaeozoic arthropod assemblage that unites trilobites with several other lineages that share similar appendage structure. Post-embryonic development of the exoskeleton is well documented for some trilobitomorphs, especially trilobites, but little is known of the ontogeny of their soft parts, limiting understanding of their autecology. Here we document appendage structure of the Cambrian naraoiid trilobitomorph Naraoia spinosa by computed microtomography, resulting in three-dimensional reconstructions of appendages at both juvenile and adult stages....
Data from: Helping decisions and kin recognition in long-tailed tits: is call similarity used to direct help towards kin?Amy Leedale, Robert Lachlan, Elva Robinson & Ben Hatchwell
Most cooperative breeders live in discrete family groups, but in a minority, breeding populations comprise extended social networks of conspecifics that vary in relatedness. Selection for effective kin recognition may be expected for individuals in such kin neighbourhoods to maximise indirect fitness. Using a long-term social pedigree, molecular genetics, field observations and acoustic analyses, we examine how vocal similarity affects helping decisions in the long-tailed tit Aegithalos caudatus. Long-tailed tits are cooperative breeders in which...
Understanding complex responses of multiple character suites (e.g., behaviour, life history, morphology) to multifarious environments is a challenging task. Here we use a multivariate approach (partial least squares structural equation modelling) to disentangle drivers (i.e., predation, resource availability, and population demographics) of phenotypic divergence among populations of Bahamas mosquitofish (Gambusia hubbsi) inhabiting blue holes. We further employ a two-block partial least squares analysis in a novel approach to uncovering integrated and independent aspects of divergence...
Sulfoximine-based insecticides, such as sulfoxaflor, are of increasing global importance and have been registered for use in 81 countries, offering a potential alternative to neonicotinoid insecticides. Previous studies have demonstrated that sulfoxaflor exposure can have a negative impact on the reproductive output of bumblebee colonies, but the specific life-history variables that underlie these effects remain unknown. Here, we used a microcolony-based protocol to assess the sub-lethal effects of chronic sulfoxaflor exposure on egg laying, larval...
Geographical and temporal variation of multiple paternity in invasive mosquitofish (Gambusia holbrooki, Gambusia affinis)Jiancao Gao, Francesco Santi, Linjun Zhou, Xiaoqin Wang, Rüdiger Riesch & Martin Plath
Multiple paternity (MP) increases offspring’s genetic variability, which could be linked to invasive species’ evolvability in novel distribution ranges. Shifts in MP can be adaptive, with greater MP in harsher/colder environments or towards the end of the reproductive season, but climate could also affect MP indirectly via its effect on reproductive life histories. We tested these hypotheses by genotyping N = 2,903 offspring from N = 306 broods of two closely related livebearing fishes, Gambusia...
