title: Data from: Origin of the chromosomal radiation of Madeiran house mice: a microsatellite analysis of metacentric chromosomes

description: Chromosome races of Mus musculus domesticus are characterised by
 particular sets of metacentric chromosomes formed by Robertsonian fusions
 and whole-arm reciprocal translocations. The Atlantic island of Madeira is
 inhabited by six chromosome races of house mice with 6–9 pairs of
 metacentric chromosomes. Three of these races are characterised by the
 metacentric 3.8 also found elsewhere in the distribution of M. m.
 domesticus, including Denmark and Spain. We investigated the possibility
 that metacentric 3.8 was introduced to Madeira during the initial
 colonisation, as this could have ‘seeded’ the cascade of chromosomal
 mutation that is the basis of the extraordinary chromosomal radiation
 observed on the island. Variation at 24 microsatellite loci mapping to
 three different chromosomal regions (proximal, interstitial and distal) of
 mouse chromosomes 3 and 8 was investigated in 179 mice from Madeira,
 Denmark, Portugal, Spain, Italy and Scotland. Analyses of microsatellite
 loci closely linked to the centromeres of these chromosomes (‘proximal
 loci’) do not support a common evolutionary origin of metacentric 3.8
 among Madeiran, Danish and Spanish mouse populations. Our results suggest
 that Madeiran mice are genetically more similar to standard karyotype mice
 from Portugal than to metacentric mice from elsewhere. There is expected
 to be an interruption to gene flow between hybridising metacentric races
 on Madeira, particularly in the chromosomal regions close to the
 rearrangement breakpoints. Consistent with this, relating to
 differentiation involving chromosomes 3 and 8 on Madeira, we found greater
 genetic structure among races for proximal than interstitial or distal
 loci.

title: Data from: Sex differences in lifespan: females homozygous for the X chromosome do not suffer the shorter lifespan predicted by the unguarded X hypothesis

description: Lifespan differs between the sexes in many species. Three hypotheses to
 explain this interesting pattern have been proposed, involving different
 drivers: sexual selection, asymmetrical inheritance of cytoplasmic
 genomes, and hemizygosity of the X(Z) chromosome (the unguarded X
 hypothesis). Of these, the unguarded X has received the least experimental
 attention. This hypothesis suggests that the heterogametic sex suffers a
 shortened lifespan because recessive deleterious alleles on its single
 X(Z) chromosome are expressed unconditionally. In Drosophila melanogaster,
 the X chromosome is unusually large (~20% of the genome), providing a
 powerful model for evaluating theories involving the X. Here, we test the
 unguarded X hypothesis by forcing D. melanogaster females from a
 laboratory population to express recessive X-linked alleles to the same
 degree as males, using females exclusively made homozygous for the X
 chromosome. We find no evidence for reduced lifespan or egg-to-adult
 viability due to X homozygozity. In contrast, males and females homozygous
 for an autosome both suffer similar, significant reductions in those
 traits. The logic of the unguarded X hypothesis is indisputable, but our
 results suggest that the degree to which recessive deleterious X-linked
 alleles depress performance in the heterogametic sex appears too small to
 explain general sex differences in lifespan.

title: Data from: Linking GPS telemetry surveys and scat analyses helps explain variability in black bear foraging strategies

description: Studying diet is fundamental to animal ecology and scat analysis, a
 widespread approach, is considered a reliable dietary proxy. Nonetheless,
 this method has weaknesses such as non-random sampling of habitats and
 individuals, inaccurate evaluation of excretion date, and lack of
 assessment of inter-individual dietary variability. We coupled GPS
 telemetry and scat analyses of black bears Ursus americanus Pallas to
 relate diet to individual characteristics and habitat use patterns while
 foraging. We captured 20 black bears (6 males and 14 females) and fitted
 them with GPS/Argos collars. We then surveyed GPS locations shortly after
 individual bear visits and collected 139 feces in 71 different locations.
 Fecal content (relative dry matter biomass of ingested items) was
 subsequently linked to individual characteristics (sex, age, reproductive
 status) and to habitats visited during foraging bouts using Brownian
 bridges based on GPS locations prior to feces excretion. At the population
 level, diet composition was similar to what was previously described in
 studies on black bears. However, our individual-based method allowed us to
 highlight different intra-population patterns, showing that sex and female
 reproductive status had significant influence on individual diet. For
 example, in the same habitats, females with cubs did not use the same food
 sources as lone bears. Linking fecal content (i.e., food sources) to
 habitat previously visited by different individuals, we demonstrated a
 potential differential use of similar habitats dependent on individual
 characteristics. Females with cubs-of-the-year tended to use old forest
 clearcuts (6–20 years old) to feed on bunchberry, whereas females with
 yearling foraged for blueberry and lone bears for ants. Coupling GPS
 telemetry and scat analyses allows for efficient detection of
 inter-individual or inter-group variations in foraging strategies and of
 linkages between previous habitat use and food consumption, even for
 cryptic species. This approach could have interesting ecological
 implications, such as supporting the identification of habitats types
 abundant in important food sources for endangered species targeted by
 conservation measures or for management actions for depredating animals.

title: Data from: Effect of competitive cues on reproductive morphology and behavioural plasticity in male fruitflies

description: Phenotypic plasticity will be favored whenever there are significant
 fitness benefits of responding to environmental variation. The extent and
 nature of the plasticity that evolves depends on the rate of environmental
 fluctuations and the capacity to track and respond to that variability.
 Reproductive environments represent one arena in which changes can be
 rapid. The finding that males of many species show morphological,
 physiological, and behavioral plasticity in response to premating and
 postmating reproductive competition (RC) suggests that plasticity is
 broadly beneficial. The developmental environment is expected to
 accurately predict the average population level of RC but to be a
 relatively poor indicator of immediate RC at any particular mating.
 Therefore, we predict that manipulation of average RC during development
 should cause a response in plasticity “set” during development (e.g., size
 of adult reproductive structures), but not in flexible plasticity
 determined by the immediate adult environment (e.g., behavioral plasticity
 in mating duration). We tested this prediction in Drosophila melanogaster
 males by manipulating 2 independent cues of average RC during development:
 1) larval density and 2) the presence or absence of adult males within
 larval culture vials. Consistent with the prediction, both manipulations
 resulted in the development of males with significantly larger adult
 accessory glands (although testis size decreased when males were added to
 culture vials). There was no effect on adult plasticity (mating duration,
 extended mating in response to rivals). The results suggest that males
 have evolved independent responses to long- and short-term variation in
 RC.

title: Data from: Identification of candidate effector genes of Pratylenchus penetrans

description: Pratylenchus penetrans is one of the most important species among root
 lesion nematodes (RLNs) due to the detrimental and economic impact that it
 causes in a wide range of crops. Similar to other plant-parasitic
 nematodes (PPNs), P. penetrans harbors a significant number of secreted
 proteins that play key roles during parasitism. Here we combined spatially
 and temporally resolved next generation sequencing datasets of P.
 penetrans to select a list of candidate genes aimed at the identification
 of a panel of effector genes for this species. We determined the spatial
 expression of transcripts of 22 candidate effectors within the esophageal
 glands of P. penetrans by in situ hybridization. These comprised
 homologues of known effectors of other PPNs with diverse putative
 functions, as well as novel pioneer effectors specific to RLNs. It is
 noteworthy that five of the pioneer effectors encode extremely
 proline-rich proteins. We then combined in situ localization of effectors
 with available genomic data to identify a non-coding motif enriched in
 promoter regions of a subset of P. penetrans effectors, and thus a
 putative hallmark of spatial expression. Expression profiling analyses of
 a subset of candidate effectors confirmed their expression during plant
 infection. Our current results provide the most comprehensive panel of
 effectors found for RLNs. Considering the damage caused by P. penetrans,
 this information provides valuable data to elucidate the mode of
 parasitism of this nematode and offers useful suggestions regarding the
 potential use of P. penetrans-specific target effector genes to control
 this important pathogen. This article is protected by copyright. All

title: Data from: Impact of cryptic female choice on insemination success: larger sized and longer copulating male squid ejaculate more, but females influence insemination success by removing spermatangia

description: In polyandrous mating systems, sperm competition and cryptic female choice
 (CFC) are well recognized as postcopulatory evolutionary forces. However,
 it remains challenging to separate CFC from sperm competition and to
 estimate how much CFC influences insemination success because those
 processes usually occur inside the female's body. The Japanese pygmy
 squid, Idiosepius paradoxus, is an ideal species in which to separate CFC
 from sperm competition because sperm transfer by the male and sperm
 displacement by the female can be observed directly at an external
 location on the female's body. Here, we counted the number of
 spermatangia transferred to, removed from, and remaining on the female
 body during single copulation episodes. We measured behavioral and
 morphological characteristics of the male, such as duration of copulation
 and body size. Although males with larger body size and longer copulation
 time were capable of transferring larger amounts of sperm, females
 preferentially eliminated sperm from males with larger body size and
 shorter copulation time by spermatangia removal; thus, CFC could attenuate
 sperm precedence by larger males, whereas it reinforces sperm precedence
 by males with longer copulation time. Genetic paternity analysis revealed
 that fertilisation success for each male was correlated with remaining
 sperm volume that is adjusted by females after copulation.

title: Data from: Differential activation of serotonergic neurones during short- and long-term gregarisation of desert locusts

description: Serotonin is a neurochemical with evolutionarily conserved roles in
 orchestrating nervous system function and behavioural plasticity. A
 dramatic example is the rapid transformation of desert locusts from
 cryptic asocial animals into gregarious crop pests that occurs when
 drought forces them to accumulate on dwindling resources, triggering a
 profound alteration of behaviour within just a few hours. The onset of
 crowding induces a surge in serotonin within their thoracic ganglia that
 is sufficient and necessary to induce the switch from solitarious to
 gregarious behaviour. To identify the neurons responsible, we have
 analysed how acute exposure to three gregarizing stimuli—crowding,
 touching the hind legs or seeing and smelling other locusts—and prolonged
 group living affect the expression of serotonin in individual neurons in
 the thoracic ganglia. Quantitative analysis of cell body
 immunofluorescence revealed three classes of neurons with distinct
 expressional responses. All ganglia contained neurons that responded to
 multiple gregarizing stimuli with increased expression. A second class
 showed increased expression only in response to intense visual and
 olfactory stimuli from conspecifics. Prolonged group living affected a
 third and entirely different set of neurons, revealing a two-tiered role
 of the serotonergic system as both initiator and substrate of socially
 induced plasticity. This demonstrates the critical importance of
 ontogenetic time for understanding the function of serotonin in the
 reorganization of behaviour.

The cells occur in left-right pairs and each data-point is an average of left and right values.

title: Data from: Age-dependent variation in the terminal investment threshold in male crickets

description: The terminal investment hypothesis proposes that decreased expectation of
 future reproduction (e.g., arising from a threat to survival) should
 precipitate increased investment in current reproduction. The level at
 which a cue of decreased survival is sufficient to trigger terminal
 investment (i.e., the terminal investment threshold) may vary according to
 other factors that influence expectation for future reproduction. We test
 whether the terminal investment threshold varies with age in male
 crickets, using heat-killed bacteria to simulate an immune-inducing
 infection. We measured calling effort (a behavior essential for mating)
 and hemolymph antimicrobial activity in young and old males across a
 gradient of increasing infection cue intensity. There was a significant
 interaction between the infection cue and age in their effect on calling
 effort, confirming the existence of a dynamic terminal investment
 threshold: young males reduced effort at all infection levels, whereas old
 males increased effort at the highest levels relative to naïve
 individuals. A lack of a corresponding decrease in antibacterial activity
 suggests that altered reproductive effort is not traded against investment
 in this component of immunity. Collectively, these results support the
 existence of a dynamic terminal investment threshold, perhaps accounting
 for some of the conflicting evidence in support of terminal investment.

title: Data from: Oxidative status and social dominance in a wild cooperative breeder

description: 1. Oxidative stress has been proposed as a key mediator of life-history
 trade-offs, yet the social factors that affect patterns of oxidative
 states amongst individuals in animal societies remain virtually
 unexplored. 2. This is important, as rank-related differences in
 reproductive effort in many social species have the potential to generate,
 or indeed arise from, differences in oxidative state across dominance
 classes. 3. Here, we examine rank-related variation in oxidative states
 before and after a lengthy breeding season in a wild cooperatively
 breeding bird with high reproductive skew in the semi-arid zone of
 Southern Africa; the white-browed sparrow weaver (Plocepasser mahali). 4.
 Our findings reveal that prior to breeding, neither sex showed
 rank-related differences in markers of oxidative damage or antioxidant
 protection, suggesting that dominants’ reproductive monopolies do not
 arise from superior pre-breeding oxidative states. 5. After breeding,
 however, females (who provision young at higher rates than males) suffered
 elevated oxidative damage, and dominant females (the only birds to lay and
 incubate eggs, and the primary nestling provisioners) experienced
 differential declines in antioxidant protection. 6. While males also
 showed reduced antioxidant capacity after breeding, this decline was
 rank-independent and not associated with elevated oxidative damage. 7. Our
 findings suggest that divisions of labour in animal societies can leave
 the hardest-working classes differentially exposed to oxidative stress,
 raising the possibility of hitherto unexplored impacts on health and
 ageing in social species.

title: Data from: Breeding synchrony and predator specialization: a test of the predator swamping hypothesis in seabirds

description: Reproductive synchrony is a widespread phenomenon that is predicted to be
 adaptive for prey with specialist predators but not for those with
 generalist ones. I tested this prediction in three polar seabird species
 characterized by different levels of predator specialization. In the
 Antarctic petrel, for which the only predator was highly specialized,
 hatching dates were highly synchronous and chicks that hatched close to
 the mean hatching date had a higher survival. In black-legged kittiwakes
 and Brünnich’s guillemots, whose predators were generalists, breeding was
 less synchronous and there was no fitness advantage in hatching close to
 the mean. This study emphasizes the potential importance of the relative
 timing of reproduction for individual fitness and supports the hypothesis
 that the adaptive value of breeding synchrony depends on the predator
 functional response.
