Data from: Give the machine a hand: a Boolean time-based decision-tree template for rapidly finding animal behaviours in multi-sensor data

Rory P. Wilson, Mark D. Holton, Agustina Di Virgilio, Hannah Williams, Emily L. C. Shepard, Sergio Lambertucci, Flavio Quintana, Juan E Sala, Bharathan Balaji, Eun Sun Lee, Mani Srivastava, D. Michael Scantlebury & Carlos M. Duarte
1. The development of multi-sensor animal-attached tags, recording data at high frequencies, has enormous potential in allowing us to define animal behaviour. 2. The high volumes of data, are pushing us towards machine-learning as a powerful option for distilling out behaviours. However, with increasing parallel lines of data, systems become more likely to become processor limited and thereby take appreciable amounts of time to resolve behaviours. 3. We suggest a Boolean approach whereby critical changes...

Data from: Comprehensive phylogeny of ray-finned fishes (Actinopterygii) based on transcriptomic and genomic data

Lily C. Hughes, Guillermo Ortí, Yu Huang, Ying Sun, Carole C. Baldwin, Andrew W. Thompson, Dahiana Arcila, Ricardo Betancur-R, Chenhong Li, Leandro Becker, Nicolás Bellora, Xiaomeng Zhao, Xiaofeng Li, Min Wang, Chao Fang, Bing Xie, Zhuocheng Zhou, Hai Huang, Songlin Chen, Byrappa Venkatesh & Qiong Shi
Our understanding of phylogenetic relationships among bony fishes has been transformed by analysis of a small number of genes, but uncertainty remains around critical nodes. Genome-scale inferences so far have sampled a limited number of taxa and genes. Here we leveraged 144 genomes and 159 transcriptomes to investigate fish evolution with an unparalleled scale of data: >0.5 Mb from 1,105 orthologous exon sequences from 303 species, representing 66 out of 72 ray-finned fish orders. We...

Data from: Coordinated species importation policies are needed to reduce serious invasions globally: the case of alien bumblebees in South America

Marcelo A. Aizen, Cecilia Smith-Ramirez, Carolina L. Morales, Lorena Vieli, Agustín Sáez, Rodrigo M. Barahona-Segovia, Marina P. Arbetman, José Montalva, Lucas A. Garibaldi, David W. Inouye & Lawrence D. Harder
The global trade of species promotes diverse human activities but also facilitates the introduction of potentially invasive species into new environments. As species ignore national boundaries, unilateral national decisions concerning species trade set the stage for transnational species invasion with significant conservation, economic and political consequences. The need for a coordinated approach to species importation policies is demonstrated by the introduction of two bumblebee species into Chile for crop pollination, despite Argentina banning commercial importation...

Data from: Diet complementation as a frequency‐dependent mechanism conferring advantages to rare plants via dispersal

Teresa Morán López, Tomas A. Carlo, Guillermo Amico & Juan Manuel Morales
1. We used an agent-based model to test the hypothesis that diet complementation by frugivores can promote the persistence of rare plant species in communities (DCH). 2. Models simulated bird movement, frugivory, seed-dispersal, and plant recruitment on landscapes that differed in their degree of fragmentation and in their degree of fruiting species mixing at the scale of frugivores’ foraging decisions. 3. Diet complementation promoted the dispersal of rare-species without the need of a priori preference...

Data from: Severity of impacts of an introduced species corresponds with regional eco-evolutionary experience

Kimberley T. Davis, Ragan M. Callaway, Alex Fajardo, Anibal Pauchard, Martin A Nunez, Rob W Brooker, Bruce D. Maxwell, Romina D Dimarco, Duane A Peltzer, Bill Mason, Seppo Ruotsalainen, Anne C S McIntosh, Robin J Pakeman, Alyssa Laney Smith & Michael Gundale
Invasive plant impacts vary widely across introduced ranges. We tested the hypothesis that differences in the eco-evolutionary experience of native communities with the invader correspond with the impacts of invasive species on native vegetation, with impacts increasing with ecological novelty. We compared plant species richness and composition beneath Pinus contorta to that in adjacent vegetation and other P. contorta stands across a network of sites in its native (Canada and USA) and non-native (Argentina, Chile,...

Data from: An overlooked plant-parakeet mutualism counteracts human overharvesting on an endangered tree

Karina L. Speziale, Sergio A. Lambertucci, Gabriela Gleiser, José L. Tella, Fernando Hiraldo & Marcelo A. Aizen
The exponential growth of the human population often causes the overexploitation of resources and disruption of ecological interactions. Here we propose that the antagonist effect of humans on exploited species might be alleviated with the advent of a second predator species. We focused on the complex interactions between an endangered conifer (Araucaria araucana) and two seed exploiters: the Austral parakeet (Enicognathus ferrugineus) and human seed collectors. We tested the importance of partial seed consumption by...

Data from: Linking biological soil crust attributes to the multifunctionality of vegetated patches and interspaces in a semiarid shrubland

Irene A. Garibotti, Marina Gonzalez Polo & Solana Tabeni
1.Understanding the importance of biotic community structure on ecosystem functioning, and whether communities inhabiting different microhabitats in highly heterogeneous areas provide different ecological functions is a challenge in ecological research in the face of biodiversity and habitat loss. Biological soil crusts (BSCs) have been largely treated as unique entities, and have been mostly examined in interspaces between perennial plants, limiting current understanding of their role as drivers of ecosystem functioning and their relative contribution in...

Data from: Tracking data and retrospective analyses of diet reveal the consequences of loss of marine subsidies for an obligate scavenger, the Andean condor

Sergio A. Lambertucci, Joan Navarro, Jose Antonio Sánchez-Zapata, Keith A. Hobson, Pablo A.E. Alarcón, Guillermo Wiemeyer, Guillermo Blanco, Fernando Hiraldo & Jose Antonio Donazar
Over the last century, marine mammals have been dramatically reduced in the world’s oceans. We examined evidence that this change caused dietary and foraging pattern shifts of the Andean condor (Vultur gryphus) in Patagonia. We hypothesized that, after the decrease in marine mammals and the increase in human use of coastlines, condor diet changed to a more terrestrial diet which, in turn, influenced their foraging patterns. We evaluated the diet by means of stable isotope...

Data from: Luck in food-finding affects individual performance and population trajectories

Rory P. Wilson, Andrew Neate, Mark D. Holton, Emily L.C. Shepard, D. Michael Scantlebury, Sergio A. Lambertucci, Agustina Di Virgilio, Elaine Crooks, Christina Mulvenna & Nikki Marks
Energy harvesting by animals is important because it provides the power needed for all metabolic processes. Beyond this, efficient food-finding enhances individual fitness [1] and population viability [2], although rates of energy accumulation are affected by the environment and food distribution. Typically, differences between individuals in the rate of food acquisition are attributed to varying competencies [3] even though food encounter rates are known to be probabilistic [4]. We used animal-attached technology to quantify food...

Data from: Influences of fire–vegetation feedbacks and post-fire recovery rates on forest landscape vulnerability to altered fire regimes

Alan J. Tepley, Enrique Thomann, Thomas T. Veblen, George L.W. Perry, Andrés Holz, Juan Paritsis, Thomas Kitzberger, Kristina J. Anderson-Teixeira & George L. W. Perry
1. In the context of on-going climatic warming, forest landscapes face increasing risk of conversion to non-forest vegetation through alteration of their fire regimes and their post-fire recovery dynamics. However, this pressure could be amplified or dampened, depending on how fire-driven changes to vegetation feed back to alter the extent or behavior of subsequent fires. 2. Here we develop a mathematical model to formalize understanding of how fire–vegetation feedbacks and the time to forest recovery...
