Data from: Temporal dynamics of snowmelt nutrient release from snow–plant residue mixtures: an experimental analysis and mathematical model development

Diogo Costa, Jian Liu, Jennifer Roste & Jane Elliott
Reducing eutrophication in surface water is a major environmental challenge in many countries around the world. In cold Canadian prairie agricultural regions, part of the eutrophication challenge arises during spring snowmelt when a significant portion of the total annual nutrient export occurs, and plant residues can act as a nutrient source instead of a sink. Although the total mass of nutrients released from various crop residues has been studied before, little research has been conducted...

Data from: A novel alarm signal in aquatic prey: Familiar minnows coordinate group defences against predators through chemical disturbance cues

Kevin R. Bairos-Novak, Maud C. O. Ferrari & Douglas P. Chivers
Animal signalling systems outside the realm of human perception remain largely understudied. These systems consist of four main components: a signalling context, a voluntary signal, receiver responses and resulting fitness benefits to both the signaller and receiver(s). It is often most difficult to determine incidental cues from voluntary signals. One example is chemical disturbance cues released by aquatic prey during predator encounters that may serve to alert conspecifics of nearby risk and initiate tighter shoaling....

Data from: Conservation through the lens of (mal)adaptation: concepts and meta-analysis

Alison Derry, Dylan Fraser, Steven Brady, Louis Astorg, Elizabeth Lawrence, Gillian Martin, Jean-Michel Matte, Jorge Octavio Negrín Dastis, Antoine Paccard, Rowan Barrett, Lauren Chapman, Jeffrey Lane, Chase Ballas, Marissa Close & Erika Crispo
Evolutionary approaches are gaining popularity in conservation science, with diverse strategies applied in efforts to support adaptive population outcomes. Yet conservation strategies differ in the type of adaptive outcomes they promote as conservation goals. For instance, strategies based on genetic or demographic rescue implicitly target adaptive population states whereas strategies utilizing transgenerational plasticity or evolutionary rescue implicitly target adaptive processes. These two goals are somewhat polar: adaptive state strategies optimize current population fitness, which should...

Data from: Safety cues can give prey more valuable information than danger cues

Barney Luttbeg, Maud C O Ferrari, Daniel T Blumstein & Douglas P Chivers
The ability of prey to assess predation risk is fundamental to their success. It is routinely assumed predator cues do not vary in reliability across levels of predation risk. We propose that cues can differ in how precisely they indicate different levels of predation risk. What we call danger cues precisely indicate high risk levels, while safety cues precisely indicate low risk levels. Using optimality modeling, we find that prey fitness is increased when prey...

Data from: Microhabitat complexity influences fear acquisition in fathead minnows

Adam Crane, Maud Ferrari, Ita Rivera-Hernandez & Grant Brown
Habitat varies in structure, with animals often preferring a certain degree of microhabitat complexity that facilitates fitness-related activities such as predator avoidance. Environments with high predation risk can induce elevated baseline fear and neophobia in prey, but whether microhabitat complexity influences the acquisition of neophobia has yet to be reported. Here, we tested whether exposure to predation risk induces different levels of fear in microhabitats that differed in complexity. We exposed fathead minnows, Pimephales promelas,...

Data from: Resistance of soil biota and plant growth to disturbance increases with plant diversity

Jonathan Bennett, Alexander Koch, Jennifer Forsythe, Nancy Johnson, David Tilman & John Klironomos
Plant diversity is critical to the functioning of ecosystems, potentially mediated in part by interactions with soil biota. Here, we characterized multiple groups of soil biota across a plant diversity gradient in a long-term experiment. We then subjected soil samples taken along this gradient to drought, freezing, and a mechanical disturbance to test how plant diversity affects the responses of soil biota and growth of a focal plant to these disturbances. High plant diversity resulted...

Not a melting pot: plant species aggregate in their non-native range

Gisela C. Stotz, James F. Cahill, Jonathan A. Bennett, Cameron N. Carlyle, Edward W. Bork, Diana Askarizadeh, Sandor Bartha, Carl Beierkuhnlein, Bazartseren Boldgiv, Leslie Brown, Marcelo Cabido, Giandiego Campetella, Stefano Chelli, Ofer Cohen, Sandra Díaz, Lucas Enrico, David Ensing, Batdelger Erdenetsetseg, Alessandra Fidelis, Heath W. Garris, Hugh A.L. Henry, Anke Jentsch, Mohammad Hassan Jouri, Kadri Koorem, Peter Manning … & Lauchlan H. Fraser
Aim: Plant species continue to be moved outside of their native range by human activities. Here, we aim at determining whether, once introduced, plants assimilate into native communities, or whether they aggregate, thus forming mosaics of native- and alien-rich communities. Alien species may aggregate in their non-native range due to shared habitat preferences, such as their tendency to establish in high-biomass, species-poor areas. Location: 22 herbaceous grasslands in 14 countries, mainly in the temperate zone....

Data from: Publication reform to safeguard wildlife from researcher harm

Kate A. Field, Paul C. Paquet, Kyle Artelle, Gilbert Proulx, Ryan K. Brook & Chris T. Darimont
Despite abundant focus on responsible care of laboratory animals, we argue that inattention to the maltreatment of wildlife constitutes an ethical blind spot in contemporary animal research. We begin by reviewing significant shortcomings in legal and institutional oversight, arguing for the relatively rapid and transformational potential of editorial oversight at journals in preventing harm to vertebrates studied in the field and outside the direct supervision of institutions. Straightforward changes to animal care policies in journals,...

Data from: Cognitive resonance: when information carry-over constrains cognitive plasticity

Maud C. O. Ferrari, Marianna E. Horn & Douglas P. Chivers
1. When faced with a changing environment, some species appear to adapt quickly, while others seem unable to update the value of environmental cues on which they base their decisions, leading them to display seemingly maladaptive responses. 2. While behavioural and cognitive plasticity are two traits that should predict the ability of species to update the value of environmental cues, we argue that this flexibility may be constrained by ontogeny. While sensitive periods have been...

Data from: Environmental and demographic drivers of male mating success vary across sequential reproductive episodes in a polygynous breeder

Jeffrey A. Manning & Philip D. McLoughlin
Ecological and social factors underpinning the inequality of male mating success in animal societies can be related to sex ratio, sexual conflict between breeders, effects of non-breeders, resource dispersion, climatic conditions, and the various sequential stages of mating competition that constitute the sexual selection process. Here, we conducted an individual-based study to investigate how local resource availability and demography interact with annual climate conditions to determine the degree of male mating inequality, and thus opportunity...
