title: Data for Interindividual variation in maximum aerobic metabolism varies with gill morphology and myocardial bioenergetics in Gulf killifish

description: This study asked whether interindividual variation in maximum and standard
 aerobic metabolic rates of the Gulf killifish, Fundulus grandis, correlate
 with gill morphology and cardiac mitochondrial bioenergetics, traits
 reflecting critical steps in the O2 transport cascade from the environment
 to the tissues. Maximum metabolic rate (MMR) was positively related to
 body mass, total gill filament length, and myocardial oxygen consumption
 during maximum oxidative phosphorylation (multiple R2 = 0.836).
 Standard metabolic rate (SMR) was positively related to body mass, total
 gill filament length, and myocardial oxygen consumption during maximum
 electron transport system activity (multiple R2 = 0.717). After
 controlling for body mass, individuals with longer gill filaments, summed
 over all gill arches, or greater cardiac respiratory capacity had higher
 whole-animal metabolic rates. The overall model fit and the explanatory
 power of individual predictor variables were better for MMR than for SMR,
 suggesting that gill morphology and myocardial bioenergetics are more
 important in determining maximum rather than resting metabolism. After
 controlling for body mass, heart ventricle mass was not related to
 variation in MMR or SMR, indicating that the quality of the heart (i.e.,
 the capacity for mitochondrial metabolism) was more influential than heart
 size. Finally, myocardial oxygen consumption required to offset the
 dissipation of the transmembrane proton gradient in the absence of ATP
 synthesis was not correlated with either MMR or SMR. The results support
 the idea that interindividual variation in aerobic metabolism,
 particularly MMR, is associated with variation in specific steps in the O2
 transport cascade.

title: Fine-scale genome-wide signature of Pleistocene glaciation in Thitarodes moths (Lepidoptera: Hepialidae), host of Ophiocordyceps fungus in the Hengduan Mountains

description: The Hengduan Mountains region is a biodiversity hotspot known for its
 topologically complex, deep valleys and high mountains. While landscape
 and glacial refugia have been evoked to explain patterns of inter-species
 divergence, the accumulation of intra-species (i.e. population level)
 genetic divergence across the mountain-valley landscape in this region has
 received less attention. We used genome-wide restriction site-associated
 DNA sequencing (RADseq) to reveal signatures of Pleistocene glaciation in
 populations of Thitarodes shambalaensis (Lepidoptera: Hepialidae), the
 host moth of parasitic Ophiocordyceps sinensis (Hypocreales:
 Ophiocordycipitaceae) or "caterpillar fungus” endemic to the glacier
 of eastern Mt. Gongga. We used moraine history along the glacier valleys
 to model the distribution and environmental barriers to gene flow across
 populations of T. shambalaensis. We found that moth populations separated
 by less than 10 km exhibited valley-based population genetic clustering
 and isolation-by-distance (IBD), while gene flow among populations was
 best explained by models using information about their distributions at
 the local last glacial maximum (LGML, 58 kya), not their contemporary
 distribution. Maximum likelihood lineage history among populations, and
 among subpopulations as little as 500 meters apart, recapitulated
 glaciation history across the landscape. We also found signals of isolated
 population expansion following the retreat of LGML glaciers. These results
 reveal the fine-scale, long-term historical influence of landscape and
 glaciation on the genetic structuring of populations of an endangered and
 economically important insect species. Similar mechanisms, given enough
 time and continued isolation, could explain the contribution of glacier
 refugia to the generation of species diversity among the Hengduan
 Mountains. --

title: Giant sengi or elephant-shrew (Rhynchocyon species) interactions with Red-Capped Robin-Chat (Cossypha natalensis) and White-Chested Alethe (Chamaetylas fuelleborni) in Tanzania

description: Using camera traps and direct observations, we recorded interactions
 between three species of giant sengi (Rhynchocyon sp.) and two
 insectivorous bird species from five forests in Tanzania. In all
 instances, the birds closely followed the giant sengis who were moving and
 foraging in the leaf litter. Given the two bird species are insectivorous
 and follow ant swarms to obtain flushed prey, these interactions suggest
 that following the sengi represents an adaptive foraging strategy. Our
 observations indicate that these behaviors and associations may be more
 pervasive than previously thought.

title: Wide-range viscoelastic compression forces in microfluidics to probe cell-dependent nuclear structural and mechanobiological responses

description: The cell nucleus plays a critical role in mechanosensing and
 mechanotransduction processes, by adaptive changes of its envelope
 composition to external biophysical stimuli such as substrate rigidity and
 tensile forces. Current measurement approaches lack of precise control in
 stress application on nuclei, thus significantly impairing a complete
 mechanobiological study of cells. Here, we present a contactless
 microfluidic approach capable to exert a wide-range of viscoelastic
 compression forces (10-103 μN) -as an alternative to adhesion-related
 techniques- to induce cell-specific mechano-structural and biomolecular
 changes. We succeed in monitoring substantial nuclear modifications in
 Lamin A/C expression and coverage, diffusion processes of probing
 molecules, YAP shuttling, chromatin re-organization and cGAS pathway
 activation. As a result, high compression forces lead to a nuclear
 reinforcement (e.g. up to +20% in Lamin A/C coverage) or deconstruction
 (e.g. down to -45% in Lamin A/C coverage with a 30% reduction of chromatin
 condensation state parameter) up to cell death. We demonstrate how
 wide-range compression on suspended cells can be used as a tool to
 investigate nuclear mechanobiology and to define specific nuclear
 signatures for cell mechanical phenotyping.

title: No evidence of predicted phenotypic changes after hurricane disturbance in a shade-specialist Caribbean anole

description: Extreme climatic events (ECE) such as hurricanes have been hypothesized to
 be a major driving force of natural selection. Recent studies argue that,
 following strong hurricane disturbance, Anolis lizards in the Caribbean
 undergo selection for traits such as longer forelimbs or smaller body
 sizes that improve their clinging ability to their substrates increasing
 their chances of surviving hurricane wind gusts. Some authors challenge
 the generalization of this hypothesis arguing that other mechanisms may
 explain these phenotypic changes or that they may not necessarily be
 generalizable due to system-specific idiosyncrasies. To address this
 issue, we compared body size and relative forelimb length of Anolis
 gundlachi, a trunk-ground anole living in closed canopy forests in Puerto
 Rico, before, four months after, and 15 months after Hurricanes Irma and
 Maria in 2017. Overall, our results show no clear evidence of a temporal
 decrease in body size or increase forelimb length (relative to body size)
 challenging the generalizability of the clinging ability hypothesis.
 Understanding how animals adapt to ECE is an emerging field. Still, we are
 quickly learning that this process is complex and nuanced.
description: We captured individuals of <em>Anolis gundlachi
 </em>around the main trails of the LFDP (e.g., Otero et al. 2019;
 See Appendix 1 for more sampling details).  We restricted our analyses to
 adult individuals (&gt; 40 mm SVL). We also measured the diameter at
 breast height (DBH) of the substrate where lizards were caught. We
 quantified svl using a clear ruler, limb size using a caliper, weight
 using a pesola, and DBH using a DBH tape measure.

title: Parthenogenesis doubles the rate of amino acid substitution in Whiptail mitochondria

description: Sexual reproduction is ubiquitous in the natural world, suggesting that
 sex must have extensive benefits to overcome the cost of males compared to
 asexual reproduction. One hypothesized advantage of sex with strong
 theoretical support is that sex plays a role in removing deleterious
 mutations from the genome. Theory predicts that transitions to asexuality
 should lead to the suppression of recombination and segregation and, in
 turn, weakened natural selection, allowing for the accumulation of
 slightly deleterious mutations. We tested this prediction by estimating
 the dN/dS ratios in asexual vertebrate lineages in the
 genus Aspidoscelis using whole mitochondrial genomes
 from seven asexual and five sexual species. We found higher
 dN/dS ratios in asexual Aspidoscelis species,
 indicating that asexual whiptails accumulate non-synonymous substitutions
 due to weaker purifying selection. Additionally, we estimated nucleotide
 diversity and found that asexuals harbor significantly less diversity.
 Thus, despite their recent origins, slightly deleterious mutations
 accumulated rapidly enough in asexual lineages to be detected. We provided
 empirical evidence to corroborate the connection between asexuality and
 increased amino acid substitutions in asexual vertebrate
 lineages.

title: Data from: Shoaling in the Trinidadian guppy: Costs, benefits, and plasticity in response to an ambush predator

description: Shoaling, the formation of social groupings in fish, can provide benefits
 including reduced predation risk. However, it can also inflict costs
 including increased competition for resources, transmission of parasites,
 and salience to predators. Trinidadian guppies exhibit inter-population
 variation in shoaling behavior where individuals coexisting with large
 piscivorous predators (high predation localities) spend most of their time
 in shoals and those coexisting with an ambush predator, Rivulus hartii
 (recently, Anablepsoides hartii), that preys primarily on smaller guppies
 (low predation localities) do not. It has been suggested that this
 predator selects for reduced shoaling because doing so reduces salience to
 the predator. Here, as far as we know, we perform the first test of this
 idea. First, we investigated the effectiveness of shoaling in encounters
 with this predator. In survival trials, where one rivulus interacted with
 a group of guppies, we found that the predator was more likely to attack
 individuals in shoals than singletons. However, we also found that attacks
 directed at shoals were less likely to succeed. This suggests that the
 optimal strategy for guppies co-existing with this predator is to reduce
 shoaling to reduce the probability of being attacked, and to form shoals
 when an attack is initiated. We then asked if guppies modified their
 shoaling behavior in response to visual and olfactory cues from this
 predator during development. We found changes in guppy behavior in
 response to the treatment: guppies increased shoaling behavior when there
 was heightened risk of predation.

title: Microbiomes of guppy populations translocated in Trinidadian streams

description: An organisms’ gut microbiome can alter its fitness, yet we do not know how
 gut microbiomes change as their hosts evolve in the wild. We took
 advantage of a five-decade ‘chronosequence’ of translocated fish
 populations to examine associated changes in the gut microbiome.
 Populations of Trinidadian guppies have displayed parallel phenotypic
 convergence six times when moved from high predation (HP) to low predation
 (LP) environments. Across four drainages, we found microbiomes of fish
 translocated 5-6 years prior to sampling were already distinct from the
 microbiomes of their HP source populations. Changes in environmental
 conditions were most important in driving this shift, followed by
 phenotypic shifts in gut morphology. After 30-60 years in LP environments,
 microbiome composition was still distinct from native LP populations, but
 microbiome function was not. We found some evidence that nitrogen fixation
 enhanced gut nutrient absorption, but most functional shifts were not
 parallel across drainages. Stream-and drainage-specific signatures were
 present for both composition and function, despite our overall finding of
 consistent microbiome change across drainages. As we unravel the
 complexities of host-microbiome evolution in the wild, studies should
 consider environmental microbial colonization, host phenotypic plasticity
 in nature, and more realistic environmental conditions excluded from
 laboratory studies.
description: Researches collected guppy fish from Trinidadian streams and
 assessed stream characteristics (abiotic variables of water), fish
 morphological traits, contents of the gut to assess diet, and gut
 microbiome composition. For the latter, sequences are submitted to NCBI
 SRA (Bio-Project no. PRJNA259592) and bioinformatic code is publicly
 available (https://gitlab.msu.edu/belldere/guppy_gut_2015). Methods describing measurement of abiotic conditions, gut morphology, and gut content, are described in the manuscript (Methods and Supplementary methods). Details of the site locations and history are in Figure 1 in the MS.

title: Cardio PyMEA: A user-friendly, open-source Python application for cardiomyocyte microelectrode array analysis

description: Open source analytical software for the analysis of electrophysiological
 cardiomyocyte data offers a variety of new functionalities to complement
 closed-source, proprietary tools. Here, we present the Cardio PyMEA
 application, a free, modifiable, and open source program for the analysis
 of microelectrode array (MEA) data obtained from cardiomyocyte cultures.
 Major software capabilities include: beat detection; pacemaker origin
 estimation; beat amplitude and interval; local activation time, upstroke
 velocity, and conduction velocity; analysis of cardiomyocyte
 property-distance relationships; and robust power law analysis of
 pacemaker spatiotemporal instability. Cardio PyMEA was written entirely in
 Python 3 to provide an accessible, integrated workflow that possesses a
 user-friendly graphical user interface (GUI) written in PyQt5 to allow for
 performant, cross-platform utilization. This application makes use of
 object-oriented programming (OOP) principles to facilitate the relatively
 straightforward incorporation of custom functionalities, e.g. power law
 analysis, that suit the needs of the user. Cardio PyMEA is available as an
 open source application under the terms of the GNU General Public License
 (GPL). The source code for Cardio PyMEA can be downloaded from Github at
 the following repository: https://github.com/csdunhamUC/cardio_pymea.
description: Dataset was collected in the manner described in the
 manuscript.
description: Full MEA recordings and program executables for Windows 10 and
 Linux 5.16.16 can be found at this Box repository: https://ucla.box.com/s/vf13vjt8exxbqrsi96cd2wqkrk6otkn3. Use of the executables is not recommended; it is best to run cardio_pymea.py from the terminal and to use the Github file versions. Cardio PyMEA runs on MacOS when executed via terminal using the source files provided on Github.

title: Niche partitioning between planktivorous fish in the pelagic Baltic Sea assessed by DNA metabarcoding, qPCR and microscopy: Data and Analyses

description: Marine communities undergo rapid changes because of human-induced
 ecosystem pressures. The Baltic Sea pelagic food web has experienced
 several regime shifts during the past century, resulting in a system where
 competition between planktivorous mesopredators is assumed to be high.
 While the two clupeids sprat and herring reveal signs of competition, the
 stickleback population has increased drastically during the past decades.
 Here, we investigate diet overlap between the three dominating
 planktivorous fish in the Baltic Sea, utilizing DNA metabarcoding on the
 18S rRNA gene and the COI gene, targeted qPCR, and microscopy. Our results
 show niche differentiation between clupeids and stickleback and that
 rotifers play an important function in niche partitioning of stickleback,
 as a resource that is not being used, neither by the clupeids nor by other
 zooplankton. We further show that all the diet assessment methods used in
 this study are consistent but DNA metabarcoding describes the
 plankton-fish link at the highest taxonomic resolution. This study
 suggests that rotifers and other understudied soft-bodied prey may have an
 important function in the pelagic food web and that the growing population
 of pelagic stickleback is supported by the unutilized feeding niche
 offered by the rotifers.

title: Heterogeneity in resource competition covaries with individual variation in long-term social relationships

description: Resource competition among conspecifics is central to social evolution, as
 it serves as one of the primary selective pressures of group living. This
 is because the degree of competition for resources impacts the costs and
 benefits of social interactions. Despite this, how heterogeneity in
 resource competition drives variation in the type and quantity of
 long-term social relationships individuals foster has been overlooked. By
 measuring male mating competition and female foraging competition in a
 highly social, long-lived mammal, we demonstrate that individual variation
 in long-term intrasexual social relationships covaries with preferred
 habitat and experienced resource competition, and this effect differs
 based on the sex of the individual. Specifically, greater resource
 competition resulted in fewer social preferences, but the magnitude of the
 effect varied by both habitat and sex, whereas for social avoidances, both
 the directionality and magnitude of the effect of resource competition
 varied by habitat and sex. Together our work shows how fine-scale
 variation in individual socioecological niches (i.e., unique physical and
 social environments) can drive extensive variation in individual social
 behavior (here long-term relationships) within a population, thereby
 broadening current theories of social evolution.

title: Data from: Experimental extra-pair copulations provide proof of concept for fertility insurance in a socially monogamous bird

description: Extra-pair paternity is common among socially monogamous birds, but
 whether females benefit from having extra-pair copulations remains
 unresolved. In this study I staged single extra-pair copulations in
 captive pairs of socially monogamous Japanese quail (Coturnix japonica),
 and used extra-pair males of different colour to identify extra-pair
 fertilisations. This eliminated among-female variation in extra-pair
 copulations as a source of variation in extra-pair fertilisations, and
 tested whether a single extra-pair copulation would insure against
 infertility of the social male. Overall, the probability of extra-pair
 fertilisation was 0.46 for the first egg that was fertilised after
 extra-pair copulation, but this rapidly declined over consecutive eggs in
 the laying sequence. However, a single extra-pair copulation was effective
 in ensuring fertilisation of the majority of a typical clutch in the few
 cases were the social male was completely infertile. Hence, my results
 show that variation in extra-pair paternity can be independent from
 variation in extra-pair copulation behaviour, and that a single,
 strategically timed, extra-pair copulation can largely insure against
 social male infertility. Among-female variation in extra-pair
 fertilisations, and their declining probability over the laying sequence,
 as typical for many bird species, can thus, in principle, be
 parsimoniously explained by a uniform female fertility insurance strategy.
