Methane emissions from contrasting production regions within Alberta, Canada: Implications under new federal methane regulations

Elizabeth O'Connell, David Risk, Emmaline Atherton, Evelise Bourlon, Chelsea Fougère, Jennifer Baillie & David Lowry
Aggressive reductions of oil and gas sector methane, a potent greenhouse gas, have been proposed in Canada. Few large-scale measurement studies have been conducted to confirm a baseline. This study used a vehicle-based gas monitoring system to measure fugitive and vented gas emissions across Lloydminster (heavy oil), Peace River (heavy oil/bitumen), and Medicine Hat (conventional gas) developments in Alberta, Canada. Four gases (CO2, CH4, H2S, C2H6), and isotopic δ13CCH4 were recorded in real-time at 1...

Data from: Quantifying the impact of pesticides on learning and memory in bees

Harry Siviter, Julia Koricheva, Mark J.F. Brown, Ellouise Leadbeater & Mark J. F. Brown
1) Most insecticides are insect neurotoxins. Evidence is emerging that sublethal doses of these neurotoxins are affecting learning and memory of both wild and managed bee colonies; exacerbating the negative effects of pesticide exposure and reducing individual foraging efficiency. 2) Variation in methodologies and interpretation of results across studies has precluded the quantitative evaluation of these impacts that is needed to make recommendations for policy change. It is not clear whether robust effects occur under...

Data from: A land classification protocol for pollinator ecology research: an urbanisation case study

Ash E. Samuelson & Ellouise Leadbeater
1. Land-use change is one of the most important drivers of widespread declines in pollinator populations. Comprehensive quantitative methods for land classification are critical to understanding these effects, but co-option of existing human-focussed land classifications is often inappropriate for pollinator research. 2. Here we present a flexible GIS-based land classification protocol for pollinator research using a bottom-up approach driven by reference to pollinator ecology, with urbanisation as a case study. Our multi-step method involves manually...

Data from: The relative importance of plant intraspecific diversity in structuring arthropod communities: a meta-analysis

Julia Koricheva & Dexter Hayes
1. Understanding how plant diversity influences higher trophic levels is important for predicting the consequences of global biodiversity loss. While early studies have focused on the effects of plant species richness, more recently a growing number of experiments have explored the effects of plant intraspecific diversity by manipulating the genotypic richness of plant communities. 2. By combining 162 estimates of effect size from 60 experimental studies, we examined the effects of plant genotypic richness on...

Data from: Lower bumblebee colony reproductive success in agricultural compared to urban environments

Ash E. Samuelson, Richard J. Gill, Mark J.F. Brown, Ellouise Leadbeater & Mark J. F. Brown
Urbanisation represents a rapidly growing driver of land-use change. While it is clear that urbanisation impacts species abundance and diversity, direct effects of urban land-use on animal reproductive success are rarely documented. Here we show that urban land-use is linked to long-term colony reproductive output in a key pollinator. We reared colonies from wild-caught bumblebee (Bombus terrestris) queens, placed them at sites characterised by varying degrees of urbanisation from inner city to rural farmland, and...

Data from: A Tournaisian (earliest Carboniferous) conglomerate-preserved non-marine faunal assemblage and its environmental and sedimentological context

Jennifer A. Clack, Carys E. Bennett, Sarah J. Davies, Andrew C. Scott, Janet E. Sherwin & Timothy R. Smithson
A conglomerate bed from the Tournaisian Ballagan Formation of Scotland preserves a rich array of vertebrate and other non-marine fossils providing an insight into the wider ecosystem and palaeoenvironment that existed during this pivotal stage of Earth history. It challenges hypotheses of a long-lasting post-extinction trough following the end-Devonian extinction event. The fauna recovered includes a wide size range of tetrapods, rhizodonts and dipnoans, from tiny juveniles or small-bodied taxa up to large adults, and...

Data from: Biotic predictors complement models of bat and bird responses to climate and tree diversity in European forests

Luc Barbaro, Eric Allan, Evy Ampoorter, Bastien Castagneyrol, Yohan Charbonnier, Hans De Wandeler, Christian Kerbiriou, Harriet Milligan, Aude Vialatte, Monique Carnol, Marc Deconchat, Pallieter De Smedt, Herve Jactel, Julia Koricheva, Isabelle Le Viol, Bart Muys, Michael Scherer-Lorenzen, Kris Verheyen & Fons Van Der Plas
Bats and birds are key providers of ecosystem services in forests. How climate and habitat jointly shape their communities is well studied, but whether biotic predictors from other trophic levels may improve bird and bat diversity models is less known, especially across large bioclimatic gradients. Here, we achieved multi-taxa surveys in 209 mature forests replicated in six European countries from Spain to Finland, to investigate the importance of biotic predictors (i.e., the abundance or activity...

Data from: Synchronous diversification of Sulawesi's iconic artiodactyls driven by recent geological events

Laurent A. F. Frantz, Anna Rudzinski, Abang Mansyursyah Surya Nugraha, Allowen Evin, James Burton, Ardern Hulme-Beaman, Anna Linderholm, Ross Barnett, Rodrigo Vega, Evan K. Irving-Pease, James Haile, Richard Allen, Kristin Leus, Jill Shephard, Mia Hillyer, Sarah Gillemot, Jeroen Van Den Hurk, Sharron Ogle, Cristina Atofanei, Mark G. Thomas, Friederike Johansson, Abdul Haris Mustari, John Williams, Kusdiantoro Mohamad, Chandramaya Siska Damayanti … & Greger Larson
The high degree of endemism on Sulawesi has previously been suggested to have vicariant origins, dating back 40 Myr ago. Recent studies, however, suggest that much of Sulawesi’s fauna assembled over the last 15 Myr. Here, we test the hypothesis that more recent uplift of previously submerged portions of land on Sulawesi promoted diversification, and that much of its faunal assemblage is much younger than the island itself. To do so, we combined palaeogeographical reconstructions...
