Data from: A new approach for investigating spatial relationships of ichnofossils: a case study of Ediacaran–Cambrian animal traces

Emily Mitchell, Scott Evans, Zhe Chen & Shuhai Xiao
Abstract — Trace fossils record foraging behaviours, the search for resources in patchy environments, of animals in the rock record. Quantification of the strength, density and nature of foraging behaviours enables the investigation of how these may have changed through time. Here, we present a novel approach to explore such patterns using spatial point process analyses to quantify the scale and strength of ichnofossil spatial distributions on horizontal bedding planes. To demonstrate the utility of...

Dataset associated with \"Volcanic ash ice nucleation activity is variably reduced by aging in water and sulfuric acid: the effects of leaching, dissolution, and precipitation\"

William Fahy, Elena Maters, Rona Giese-Miranda, Michael P. Adams, Leif G. Jahn, Ryan Sullivan & Benjamin Murray
Volcanic ash nucleates ice when immersed in supercooled water, giving it the potential to influence weather and climate from local to global scales. However, the ice nucleation activity (INA) of ash can be modified by interaction with various chemical species during atmospheric transport. In the experimental study associated with this dataset, we show that the INA of two mineralogically distinct ash samples from Fuego and Astroni volcanoes is variably reduced when immersed in water or...

Data from: A whole-ecosystem method for experimentally suppressing ants on a small scale

Amelia S. C. Hood, Anak Agung Ketut Aryawan, Andreas D. Advento, Wahyu R. Suberkah, Adham Ashton-Butt, Sudharto Ps, Jean-Pierre Caliman, Mohammad Naim, William A. Foster & Edgar C. Turner
Ant suppression experiments have emerged as a powerful method for assessing the role of ants in ecosystems. However, traditional methods have been limited to canopy ants, and not assessed the role of ants on and below ground. Recent advances have enabled whole-ecosystem ant suppression in large plots, but large-scale experiments are not always feasible. Here, we develop a small-scale, whole-ecosystem suppression method. We compare techniques for monitoring suppression experiments, and assess whether habitat complexity in...

Recognition of discrete export signals in flagellar subunits during bacterial Type III secretion

Owain Bryant, Paraminder Dhillon, Colin Hughes & Gillian Fraser
Type III Secretion Systems (T3SS) deliver subunits from the bacterial cytosol to nascent cell surface flagella. Early flagellar subunits that form the rod and hook substructures are unchaperoned and contain their own export signals. A gate recognition motif (GRM) docks them at the FlhBc component of the FlhAB-FliPQR export gate, but the gate must then be opened and subunits must be unfolded to pass through the flagellar channel. This induced us to seek further signals...

New opabiniid diversifies the weirdest wonders of the euarthropod stem group

Joanna Wolfe, Stephen Pates, Rudy Lerosey-Aubril, Allison C. Daley & Javier Ortega-Hernández
Once considered ‘weird wonders’ of the Cambrian, the emblematic Burgess Shale animals Anomalocaris and Opabinia are now recognized as lower stem group euarthropods and have provided crucial data for constraining the polarity of key morphological characters in the group. Anomalocaris and its relatives (radiodonts) had a worldwide distribution and survived until at least the Devonian. However, despite intense study, Opabinia remains the only formally described opabiniid to date. Here we reinterpret a fossil from the...

Last Interglacial summer air temperature observations for the Arctic

Maria Vittoria Guarino & Louise Sime
These 21 Last Interglacial (LIG) summer surface air temperature (SSAT) observations were compiled to assess LIG Arctic sea ice (Guarino et al 2020). Twenty of the observations were also previously used in the IPCC-AR5 report. Each observation is thought to be of summer LIG air temperature anomaly relative to present day and is located in the circum-Arctic region. All sites are from north of 51N. There are 7 terrestrial based temperature records; 8 lacustrine records;...

Data from: Correcting a bias in the computation of behavioral time budgets that are based on supervised learning

Yehezkel Resheff, Hanna Bensch, Markus Zottl & Shay Rotics
Supervised learning of behavioral modes from body-acceleration data has become a widely used research tool in Behavioral Ecology over the past decade. One of the primary usages of this tool is to estimate behavioral time budgets from the distribution of behaviors as predicted by the model. These serve as the key parameters to test predictions about the variation in animal behavior. In this paper we show that the widespread computation of behavioral time budgets is...

Cuckoos that care: conspecific brood parasitism in subsocial wasps

Jeremy Field, Charlie Savill & William Foster
Hosts and brood parasites are a classic example of evolutionary conflict. Parasites lay eggs in foreign nests but typically provide no further offspring care, imposing costs on hosts. In the subsocial wasp Ammophila pubescens, eggs were often replaced by unrelated foreign females, and hosts could respond by substituting new eggs of their own. Remarkably, foreign females usually provisioned the offspring in host nests, often while hosts were also provisioning. We used field data to investigate...

Spatial clustering of trumpetfish shadowing behaviour in the Caribbean Sea revealed by citizen science

Samuel Matchette, Emily Mitchell & James Herbert-Read
The West Atlantic trumpetfish (Aulostomus maculatus) performs an unusual hunting strategy, termed shadowing, whereby a trumpetfish swims closely behind or next to another ‘host’ species to facilitate the capture of prey. Despite trumpetfish being observed throughout the Caribbean, observations of this behaviour appear to be concentrated to a handful of localities. Here we assess the degree of geographical clustering of shadowing behaviour throughout the Caribbean Sea, and identify ecological features associated with the likelihood of...

Data from: A longitudinal analysis of the growth rate and mass of tail feathers in a great tit population: ontogeny, genetic effects and relationship between traits

Ivan De La Hera, Michael S. Reichert, Gabrielle L. Davidson & John L. Quinn
Feathers have a diversity of functions in birds and are costly to produce, so their growth rate and mass can be reliable indicators of nutritional condition at the time of production. Despite the potential for feather metrics to advance our understanding of foraging, they are underused in avian ecology. One reason for this is the difficulty of interpreting whether individual variation is driven by ontogenetic, genetic, or environmental effects, which is exacerbated by the fact...

Data from: Darwin’s small and medium ground finches might have taste preferences, but not for human foods

Kiyoko Gotanda
Urbanization is rapidly changing ecological niches. On the inhabited Galapagos Islands, Darwin’s finches consume human-introduced foods preferentially; however, it remains unclear why. Here we presented pastry with flavour profiles typical of human foods (oily, salty, sweet) to small ground finches (Geospiza fuliginosa) and medium ground finches (Geospiza fortis) to test if latent taste preferences might drive selection of human foods. If human-food flavours were consumed more than a neutral or bitter control only at sites...

Disruption of the TCA cycle reveals an ATF4-mediated integration of redox and amino acid metabolism

Dylan Ryan
The Tricarboxylic Acid (TCA) cycle is arguably the most critical metabolic cycle in physiology and exists as an essential interface coordinating cellular metabolism, bioenergetics, and redox homeostasis. Despite decades of research, a comprehensive investigation into the consequences of TCA cycle dysfunction remains elusive. Here, we targeted two TCA cycle enzymes, fumarate hydratase (FH), using an FH inhibitor (FHIN-1), and succinate dehydrogenase (SDH), using two inhibitors Atpenin A5 (AA5) and thenoyltrifluoroacetone (TTFA), and combined transcriptomics, and...

Roosting behavior and roost selection by Epomophorus gambianus (Pteropodidae) in a West African rural landscape

Kofi Amponsah-Mensah, Andrew A. Cunningham, James L. N. Wood & Yaa Ntiamoa-Baidu
Urbanization is driving many species to inhabit modified landscapes, but our understanding of how species respond to this remains limited. Bats are particularly vulnerable due to their life-history traits but have received little attention. We describe the roosting behavior and roost site selection, including maternity roosts, for the Gambian epauletted fruit bat (Epomophorus gambianus) within a modified forest-savannah transition ecological zone in Ghana, West Africa. We compared characteristics of roost and non-roost sites to test...

Parasitism dramatically alters the ecosystem services provided by freshwater mussels

Joshua Brian, Sam Reynolds & David Aldridge
Parasites can indirectly affect ecosystem function by altering host phenotype, but the trait-mediated impacts of parasitism at an ecosystem level remain poorly characterised. However, understanding the influence of parasites is central to understanding the ecosystem services provided by host species, especially in an era of global environmental change. We examined the effect of native (the trematode Rhipidocotyle campanula) and invasive (the bitterling fish Rhodeus amarus) parasites, and their interaction, on the clearance rates of unionid...

Removing understory vegetation in oil palm agroforestry reduces ground-foraging ant abundance but not species richness

Amelia S.C. Hood, Andreas D. Advento, Jake Stone, Tom M. Fayle, Alice L.M. Fairnie, Helen S. Waters, William A. Foster, Jake L. Snaddon, Sudharto Ps, Jean-Pierre Caliman, Mohammad Naim & Edgar C. Turner
Ants are known to provide valuable ecosystem services in agricultural landscapes, including oil palm plantations. Their communities are less diverse and more uneven in oil palm compared with forest, and this may increase their vulnerability to disturbance. This study quantifies ant communities in oil palm agroforestry and experimentally tests their robustness to a common-practice high-disturbance management intervention: removing understory vegetation. Fieldwork was based at the Biodiversity and Ecosystem Function in Tropical Agriculture (BEFTA) Understory Vegetation...

Color and W-chromosome sequence data from study on maternal inheritance of egg mimicry

Claire N. Spottiswoode, Wenfei Tong, Gabriel A. Jamie, Katherine F. Stryjewski, Jeffrey M. DaCosta, Evan R. Kuras, Ailsa Green, Silky Hamama, Ian G. Taylor, Collins Moya & Michael D. Sorenson
This dataset supports a study demonstrating that host-specific egg mimicry in the brood-parasitic African cuckoo finch Anomalospiza imberbis is maternally inherited. It includes egg reflectance spectra for the background colour of 188 cuckoo finch eggs from four host species in Zambia, and consensus sequences for 68 W-linked ddRAD-seq loci derived from 80 female cuckoo finches belonging to four different host-specific maternal lineages from three host species in Zambia. These data derive from two partially overlapping...

Host identity matters – up to a point: the community context of Batrachochytrium dendrobatidis transmission

David Daversa, Jaime Bosch, Andy Fenton, Andrea Manica & Trent Garner
The level of detail on host communities needed to understand multi-host parasite invasions is an unresolved issue in disease ecology. Coarse community metrics that ignore functional differences between hosts, like host species richness, can be good predictors of invasion outcomes. Yet, if host species vary in the extent to which they maintain and transmit infections, then explicitly accounting for those differences may be important. Through controlled mesocosm experiments and modelling, we show that interspecific differences...

Data from: Convergent evolution of disordered lipidic structural color in the fruits of Lantana strigocamara (syn. L. camara hybrid cultivar)

Miranda Sinnott-Armstrong, Yu Ogawa, Gea Van De Kerkhof, Silvia Vignolini & Stacey Smith
Research conducted: The majority of plant colors are produced by anthocyanin and carotenoid pigments, but coloration obtained by nanostructured materials (i.e., structural colors) is increasingly reported in plants. Here, we identify a multilayer photonic structure in the fruits of Lantana strigocamara and compare it to a previously described origin in Viburnum tinus. Methods: We used a combination of transmission electron microscopy, serial EM tomography, scanning force microscopy, and optical simulations to characterize the photonic structure...

Data from: Dispersal decreases survival but increases reproductive opportunities for subordinates in a cooperative breeder

Nino Maag, Maria Paniw, Gabriele Cozzi, Marta Manser, Tim Clutton-Brock & Arpat Ozgul
In most socially structured populations, the formation of new groups depends on the survival and reproduction of dispersing individuals. Quantifying vital rates in dispersers, however, is difficult due to logistic challenges of following wide-ranging animals. Here, using data from free-ranging meerkats (Suricata suricatta), we estimated survival and reproduction of dispersing and established resident females. Meerkat groups consist of a dominant pair and several subordinate helpers. Female helpers are evicted from their resident groups by the...

Experimental evolution of a more restrained clutch size when filial cannibalism is prevented in burying beetles Nicrophorus vespilloides

Darren Rebar, Chay Halliwell, Rachel Kemp & Rebecca Kilner
The over-production of offspring is commonly associated with high hatching failure and a mechanism for dispensing with surplus young. We used experimental evolution of burying beetle populations Nicrophorus vespilloides to determine causality in these correlations. We asked: does eliminating the mechanism for killing ‘spare’ offspring cause the evolution of a more restrained clutch size, and consequently select for reduced hatching failure? N. vespilloides typically over-produces eggs but kills 1st instar larvae through partial filial cannibalism...

Hurricane disturbance accelerated the thermophilization of a Jamaican montane forest

Edmund V. J. Tanner, Peter Bellingham, John Healey & Kenneth Feeley
Thermophilization – changes in community composition towards greater relative abundances of species associated with warmer environments – has been described for plants and animals in many locations around the world. Disturbances of various kinds have increased rates of thermophilization in temperate sites, and this has been proposed, but not demonstrated, for some tropical environments. In this study, we tested whether disturbance by a Category four hurricane in 1988 (Hurricane Gilbert) increased thermophilization in a Jamaican...
