Data from: Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena)

Danuta M. Wisniewska, John M. Ratcliffe, Kristian Beedholm, Christian B. Christensen, Mark Johnson, Jens C. Koblitz, Magnus Wahlberg & Peter M. Madsen
Toothed whales use sonar to detect, locate, and track prey. They adjust emitted sound intensity, auditory sensitivity and click rate to target range, and terminate prey pursuits with high-repetition-rate, low-intensity buzzes. However, their narrow acoustic field of view (FOV) is considered stable throughout target approach, which could facilitate prey escape at close-range. Here, we show that, like some bats, harbour porpoises can broaden their biosonar beam during the terminal phase of attack but, unlike bats,...

Data from: Oilbirds produce echolocation signals beyond their best hearing range and adjust signal design to natural light conditions

Signe Brinkløv, Coen P. H. Elemans & John M. Ratcliffe
Oilbirds are active at night, foraging for fruits using keen olfaction and extremely light-sensitive eyes, and echolocate as they leave and return to their cavernous roosts. We recorded the echolocation behaviour of wild oilbirds using a multi-microphone array as they entered and exited their roosts under different natural light conditions. During echolocation, the birds produced click bursts (CBs) lasting less than 10 ms and consisting of a variable number (2–8) of clicks at 2–3 ms...

Objective: The aim of this study was to expand the spectrum of epilepsy syndromes related to STX1B, encoding the presynaptic protein syntaxin-1B, and establish genotype-phenotype correlations by identifying further disease-related variants. Methods: We used next generation sequencing in the framework of research projects and diagnostic testing. Clinical data and EEGs were reviewed, including already published cases. To estimate the pathogenicity of the variants, we used established and newly developed in silico prediction tools. Results: We...

Data from: A 2.6‐g sound and movement tag for studying the acoustic scene and kinematics of echolocating bats

Laura Stidsholt, Mark Johnson, Kristian Beedholm, Lasse Jakobsen, Kathrin Kugler, Signe Brinkløv, Angeles Salles, Cynthia F. Moss & Peter Teglberg Madsen
1. To study sensorimotor behaviour in wild animals, it is necessary to synchronously record the sensory inputs available to the animal, and its movements. To do this, we have developed a biologging device that can record the primary sensory information and the associated movements during foraging and navigating in echolocating bats. 2. This 2.6 -gram tag records the sonar calls and echoes from an ultrasonic microphone, while simultaneously sampling fine-scale movement in three dimensions from...

Data from: Vocal state change through laryngeal development

Yisi S. Zhang, Daniel Y. Takahashi, Diana A. Liao, Asif A. Ghazanfar & Coen P. H. Elemans
Across vertebrates, progressive changes in vocal behavior during postnatal development are typically attributed solely to developing neural circuits. How the changing body influences vocal development remains unknown. Here we show that state changes in the contact vocalizations of infant marmoset monkeys, which transition from noisy, low frequency cries to tonal, higher pitched vocalizations in adults, are caused partially by laryngeal development. Combining analyses of natural vocalizations, motorized excised larynx experiments, tensile material tests and high-speed...

Data from: A pace and shape perspective on fertility

Annette Baudisch & Iain Stott
1. Aging is ubiquitous to all organisms, but aging does not always mean senescence. Counter to most evolutionary theories of aging, patterns of mortality and reproduction may remain unchanged or improve with age, as well as deteriorate. Describing this diversity presents a challenge to eco-evolutionary demography. The pace-shape framework of mortality tackled this challenge to qualify and quantify orthogonal components of aging patterns in mortality. Here we extend this framework to fertility. 2. Analogous to...

The Long Lives of Primates and the 'Invariant Rate of Ageing' Hypothesis

Susan Alberts & Fernando Colchero
Is it possible to slow the rate of ageing, or do biological constraints limit its plasticity? We test the ‘invariant rate of ageing’ hypothesis, which posits that the rate of ageing is relatively fixed within species, with a collection of 39 human and nonhuman primate datasets across seven genera. We first recapitulate, in nonhuman primates, the highly regular relationship between life expectancy and lifespan equality seen in humans. We next demonstrate that variation in the...

In situ near-streambed light regime and water column dissolved oxygen and temperature measurements performed seasonally at six tributaries of Hampshire River Avon from 2013 to 2014

L. Rovelli, K. M. Attard, H. Stahl & R. N. Glud
The dataset contains time series of dissolved oxygen dynamics and near-streambed light availability from selected riverine sites within the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, greensand, chalk) and associated river morphology were investigated. Data were obtained from field-based measurements in seasonal campaigns conducted between spring 2013 and winter 2014.

Summary data of reach scale oxygen consumption and production in the streambed and in the water column at six tributaries of Hampshire River Avon collected seasonally in 2013 to 2014

L. Rovelli, K. M. Attard, H. Stahl & R. N. Glud
The dataset contains daytime and nighttime averages of oxygen production and consumption rates from representative sites at six rivers within sub-catchments of contrasting geology (clay, greensand, chalk) of the Hampshire River Avon catchment (UK). Rates were obtained for the benthic compartment using the non-invasive Aquatic Eddy Co-variance (AEC) and in the water column with sample incubations during seasonal field campaigns conducted between spring 2013 and winter 2014.

Age matters: Demographic senescence in the moss Polytrichastrum formosum

Ditte Tholstrup, Rune Halvorsen & Johan Dahlgren
It is known that many animal species senesce demographically, showing a decrease in survival and/or fertility with age. Though there is mounting evidence for and against senescence in various flowering plant species, the question of whether senescence also occurs in other plant taxa, such as mosses and other bryophytes, remains unanswered. We used GAMMs (generalized additive mixed models) and GLMMs (generalized linear mixed models) to assess effects of age on survival, size and the monocarpic...

Data from: Ecological drivers of jellyfish blooms – the complex life history of a 'well-known' medusa (Aurelia aurita)

Josephine Goldstein & Ulrich Steiner
Jellyfish blooms are conspicuous demographic events with significant ecological and socio-economic impact. Despite worldwide concern about an increased frequency and intensity of such mass occurrences, predicting their booms and busts remains challenging. Forecasting how jellyfish populations may respond to environmental change requires considering their complex life histories. Metagenic life cycles, which include a benthic polyp stage, can boost jellyfish mass occurrences via asexual recruitment of pelagic medusae. Here we present stage-structured matrix population models with...

Data from: Data gaps and opportunities for comparative and conservation biology

Dalia A. Conde, Johanna Staerk, Fernando Colchero, Rita Da Silva, Jonas Schöley, H. Maria Baden, Lionel Jouvet, John E. Fa, Hassan Syed, Eelke Jongejans, Shai Meiri, Jean-Michel Gaillard, Scott Chamberlain, Jonathan Wilcken, Owen R. Jones, Johan P. Dahlgren, Ulrich K. Steiner, Lucie M. Bland, Ivan Gomez-Mestre, Jean-Dominique Lebreton, Jaime González Vargas, Nate Flesness, Vladimir Canudas-Romo, Roberto Salguero-Gómez, Onnie Byers … & James W. Vaupel
Biodiversity loss is a major challenge. Over the past century, the average rate of vertebrate extinction has been about 100-fold higher than the estimated background rate and population declines continue to increase globally. Birth and death rates determine the pace of population increase or decline, thus driving the expansion or extinction of a species. Design of species conservation policies hence depends on demographic data (e.g., for extinction risk assessments or estimation of harvesting quotas). However,...

Data from: Aerodynamics of manoeuvring flight in brown long-eared bats (Plecotus auritus)

Per Henningsson, Lasse Jakobsen & Anders Hedenström
In this study, we explicitly examine the aerodynamics of manoeuvring flight in animals. We studied brown long-eared bats flying in a wind tunnel while performing basic sideways manoeuvres. We used particle image velocimetry in combination with high-speed filming to link aerodynamics and kinematics to understand the mechanistic basis of manoeuvres. We predicted that the bats would primarily use the downstroke to generate the asymmetries for the manoeuvre since it has been shown previously that the...
