Data from: Automated peak detection method for behavioral event identification: detecting Balaenoptera musculus and Grampus griseus feeding attempts

David A. Sweeney, Stacy L. DeRuiter, Ye Joo McNamara-Oh, Tiago A. Marques, Patricia Arranz & John Calambokidis
The desire of animal behaviorists for more flexible methods of conducting inter-study and inter-specific comparisons and meta-analysis of various animal behaviors compelled us to design an automated, animal behavior peak detection method that is potentially generalizable to a wide variety of data types, animals, and behaviors. We detected the times of feeding attempts by 12 Risso’s dolphins (Grampus griseus) and 36 blue whales (Balaenoptera musculus) using the norm-jerk (rate of change of acceleration) time series....

Data from: Extended haplodiploidy hypothesis

Petri Rautiala, Heikki Helanterä & Mikael Puurtinen
Evolution of altruistic behaviour was a hurdle for the logic of Darwinian evolution. Soon after Hamilton formalised the concept of inclusive fitness, which explains how altruism can evolve, he suggested that the high sororal relatedness brought by haplodiploidy could be why Hymenopterans have a high prevalence in eusocial species, and why helpers in Hymenoptera are always female. Later it was noted that in order to capitalize on the high sororal relatedness, helpers would need to...

Data from: Increases in local richness (α-diversity) following invasion are offset by biotic homogenization in a biodiversity hotspot

Alessandra R. Kortz & Anne E. Magurran
The world’s ecosystems are experiencing unparalleled rates of biodiversity change with invasive species implicated as one of the drivers that restructure local assemblages. Here we focus on the processes leading to biodiversity change in a biodiversity hotspot, the Brazilian Cerrado. The null expectation that invasion leads to increase in local species richness is supported by our investigation of the grass layer in two key habitats (campo sujo and campo úmido). Our analysis uncovered a linear...

Data from: Release from intralocus sexual conflict? Evolved loss of a male sexual trait demasculinises female gene expression

Jack G. Rayner, Sonia Pascoal & Nathan W. Bailey
The loss of sexual ornaments is observed across taxa, and pleiotropic effects of such losses provide an opportunity to gain insight into underlying dynamics of sex-biased gene expression and intralocus sexual conflict (IASC). We investigated this in a Hawaiian field cricket, Teleogryllus oceanicus, in which an X-linked genotype (flatwing) feminises males’ wings and eliminates their ability to produce sexually selected songs. We profiled adult gene expression across somatic and reproductive tissues of both sexes. Despite...

Data from: Species richness change across spatial scales

Jonathan M. Chase, Brian J. McGill, Patrick L. Thompson, Laura H. Antão, Amanda E. Bates, Shane A. Blowes, Maria Dornelas, Andrew Gonzalez, Anne E. Magurran, Sarah R. Supp, Marten Winter, Anne D. Bjorkmann, Helge Bruelheide, Jarrett E.K. Byrnes, Juliano Sarmento Cabral, Robin Ehali, Catalina Gomez, Hector M. Guzman, Forest Isbell, Isla H. Myers-Smith, Holly P. Jones, Jessica Hines, Mark Vellend, Conor Waldock & Mary O'Connor
Humans have elevated global extinction rates and thus lowered global-scale species richness. However, there is no a priori reason to expect that losses of global species richness should always, or even often, trickle down to losses of species richness at regional and local scales, even though this relationship is often assumed. Here, we show that scale can modulate our estimates of species richness change through time in the face of anthropogenic pressures, but not in...

Does the response of D. melanogaster males to intrasexual competitors influence sexual isolation?

Lucas Marie-Orleach, Annui M. Sanz, Nathan W. Bailey & Michael G. Ritchie
The evolutionary consequences of phenotypic plasticity are debated. For example, reproductive barriers between incipient species can depend on the social environment, but most evidence for this comes from studies focussing on the effects of experiencing heterospecific individuals of the opposite sex. In Drosophila melanogaster, males are well known to invest strategically in ejaculate components and show different courtship behaviour when reared in the presence of male competitors. It is unknown whether such plasticity in response...

Data from: Decline in abundance and apparent survival rates of fin whales (Balaenoptera physalus) in the northern Gulf of St. Lawrence

Anna Schleimer, Christian Ramp, Julien Delarue, Alain Carpentier, Martine Bérubé, Per J. Palsbøll, Richard Sears & Philip S. Hammond
Estimates of abundance and survivorship provide quantifiable measures to monitor populations and to define and understand their conservation status. This study investigated changes in abundance and survival rates of fin whales (Balaenoptera physalus) in the northern Gulf of St. Lawrence (GSL) in the context of anthropogenic pressures and changing environmental conditions. A long-term data set, consisting of 35 years of photo-identification surveys and comprising more than 5,000 identifications of 507 individuals, formed the basis of...

Data from: Behavioral responses of individual blue whales (Balaenoptera musculus) to mid-frequency military sonar

Brandon L. Southall, Stacy L. DeRuiter, Ari Friedlaender, Alison K. Stimpert, Jeremy A. Goldbogen, Elliott Hazen, Caroline Casey, Selene Fregosi, David E. Cade, Ann N. Allen, Catriona M. Harris, Greg Schorr, David Moretti, Shane Guan & John Calambokidis
This study measured the degree of behavioral responses in blue whales (Balaenoptera musculus) to controlled noise exposure off the southern California coast. High-resolution movement and passive acoustic data were obtained from non-invasive archival tags (n=42) while surface positions were obtained with visual focal follows. Controlled exposure experiments (CEEs) were used to obtain direct behavioral measurements before, during, and after simulated and operational military mid-frequency active sonar (MFAS), pseudorandom noise (PRN), and controls (no noise exposure)....

Data from: A four-questions perspective on public information use in sticklebacks (Gasterosteidae)

Mike M. Webster, Laura Chouinard-Thuly, Gábor Herczeg, Jun Kitano, Riva Riley, Sean Rogers, Michael D. Shapiro, Takahito Shikano & Kevin N. Laland
Whether learning primarily reflects general processes or species-specific challenges is a longstanding matter of dispute. Here we present a comprehensive analysis of public information use (PI-use) in sticklebacks (Gasterosteidae). PI-use is a form of social learning by which animals are able to assess the relative quality of resources, here prey patches, by observing the behaviour of others. PI-use was highly species-specific with only two of the assayed species, Pungitius spp. and their closest relative Culaea...

Network analysis reveals underlying syntactic features in a vocally learnt mammalian display, humpback whale song

Jennifer Allen, Ellen Garland, Rebecca Dunlop & Michael Noad
Vocal communication systems have a set of rules that govern the arrangement of acoustic signals, broadly defined as ‘syntax’. However, there is a limited understanding of potentially shared or analogous rules across vocal displays in different taxa. Recent work on songbirds has investigated syntax using network-based modelling. This technique quantifies features such as connectivity (adjacent signals in a sequence) and recurring patterns. Here, we apply network-based modelling to the complex, hierarchically structured songs of humpback...

Local human population increase in the non-breeding areas of long-distance migrant bird species is only weakly associated with their declines, even for synanthropic species

Will Cresswell, Winifred Nanchin & Rob Patchett
Aim: To show how recent declines in populations of long-distance migrant birds are associated with recent increases in human population growth and agricultural intensification on their tropical non-breeding grounds, except for synanthropic species, where we expect the reverse. Location: Breeding populations throughout Europe and North America spending the non-breeding season throughout Africa, and Central and South America, respectively. Methods: We mapped 50 species of long-distance migrant birds from published tagging studies of 126 breeding populations...

Data from: Northern bottlenose whales in a pristine environment respond strongly to close and distant navy sonar signals

Paul Wensveen, Saana Isojunno, Rune Hansen, Alexander Von Benda-Beckmann, Lars Kleivane, Sander Van IJsselmuide, Frans-Peter Lam, Petter Kvadsheim, Stacy DeRuiter, Charlotte Curé, Tomoko Narazaki, Peter Tyack & Patrick Miller
Impact assessments for sonar operations typically use received sound levels to predict behavioural disturbance in marine mammals. However, there are indications that cetaceans may learn to associate exposures from distant sound sources with lower perceived risk. To investigate the roles of source distance and received level in an area without frequent sonar activity, we conducted multi-scale controlled exposure experiments (n = 3) with 12 northern bottlenose whales near Jan Mayen, Norway. Animals were tagged with...

Data from: Empirical determination of severe trauma in seals from collisions with tidal turbine blades

Joe Onoufriou, Andrew Brownlow, Simon Moss, Gordon Hastie & Dave Thompson
1. Tidal energy converters (turbines) are being developed in many countries as part of attempts to reduce reliance on hydrocarbon fuels. However, the moving blades of tidal turbines pose potential collision risks for marine animals. Accurate assessment of mortality risk as a result of collisions is essential for risk management during planning and consenting processes for marine energy developments. In the absence of information on the physical consequences of such collisions, predicting likely risks relies...

Data from: Seasonal contrasts in individual consistency of oriental honey buzzards’ migration

Shoko Sugasawa & Hiroyoshi Higuchi
Individual consistency in migration can shine light on the mechanisms of migration. Most studies reported that birds are more consistent in the timing than in the routes or stopover sites during migration, but some specialist species showed the opposite patterns, being more consistent in spatial than temporal aspects of migration. One possible explanation for this contrast is that specialists rely on particular food or habitat resources, which restrict the migratory routes they can take, leading...

Data from: Long-term sound and movement recording tags to study natural behaviour and reaction to ship noise of seals

Lonnie Mikkelsen, Mark Johnson, Danuta Maria Wisniewska, Abbo Van Neer, Ursula Siebert, Peter Teglberg Madsen & Jonas Teilmann
The impact of anthropogenic noise on marine fauna is of increasing conservation concern with vessel noise being one of the major contributors. Animals that rely on shallow coastal habitats may be especially vulnerable to this form of pollution. Very limited information is available on how much noise from ship traffic individual animals experience, and how they may react to it due to a lack of suitable methods. To address this, we developed long‐duration audio and...

Habitat destruction is the single greatest anthropogenic threat to biodiversity. Decades of research on this issue have led to the accumulation of hundreds of data sets comparing species assemblages in larger, intact, habitats to smaller, more fragmented, habitats. Despite this, little synthesis or consensus has been achieved, primarily because of non‐standardized sampling methodology and analyses of notoriously scale‐dependent response variables (i.e., species richness). To be able to compare and contrast the results of habitat fragmentation...
