title: Multifunctionality of biocrusts is positively predicted by network topologies consistent with interspecies facilitation

description: The potential of biodiversity loss to impair the delivery of ecosystem
 services has motived ecologists to better understand the relationship
 between biodiversity and ecosystem functioning. Although increasing
 evidence underlines the collective contribution of different biodiversity
 components on the simultaneous performance of multiple functions
 (multifunctionality), we know little about the trade-offs between
 individual diversity effects and the extent to which they determine
 multifunctionality differentially. Here, at a sub-continental scale of 62
 dryland sites, we show in phototrophic microbiota of biological soil
 crusts (biocrusts) that, while richness alone is unable to guarantee the
 maxima of multifunctional performance, interspecies facilitation and
 compositional identity are particularly stronger but often neglected
 predictors. The inconsistent effects of different biodiversity components
 imply that soil multifunctionality can be lost despite certain species
 remaining present. Moreover, we reveal a significant empirical association
 between species functional importance and its topological feature in
 co-occurrence networks, indicating a functional signal of species
 interaction. Nevertheless, abundant species tend to isolate and merely
 interact within small topological structures, but rare species were
 tightly connected in complicated network modules. Our findings suggest
 that abundant and rare species of soil phototrophs exhibit distinct
 functional relevance. These results give a comprehensive view of how soil
 constructive species drive multifunctionality in biocrusts and ultimately
 promote a deeper understanding of the consequences of biodiversity loss in
 real-world ecosystems.

title: Data from: Age and sex as compounding factors in the relationship between cardiac mitochondrial function and type 2 diabetes in the Nile Grass rat

description: Our study revisits the role of cardiac mitochondrial adjustments during
 the progression of type 2 diabetes mellitus (T2DM), while considering age
 and sex as potential confounding factors. We used the Nile Grass rats
 (NRs) as the animal model.  After weaning, animals were fed
 either a Standard Rodent Chow Diet (SRCD group) or a Mazuri Chinchilla
 Diet (MCD group) consisting of high-fiber and low-fat content.
  Both males and females in the SRCD group, exhibited increased
 body mass, body mass index, and plasma insulin compared to the MCD group
 animals. However, the females were able to preserve their fasting blood
 glucose throughout the age range on both diets, while the males showed
 significant hyperglycemia starting at 6 months in the SRCD group. In the
 males, a higher citrate synthase activity — a marker of mitochondrial
 content — was measured at 2 months in the SRCD compared to the MCD group,
 and this was followed by a decline with age in the SRCD group only. In
 contrast, females preserved their mitochondrial content throughout the age
 range. In the males exclusively, the complex IV capacity expressed
 independently of mitochondrial content varied with age in a diet-specific
 pattern; the capacity was elevated at 2 months in the SRCD group, and at 6
 months in the MCD group. In addition, females, but not males, were able to
 adjust their capacity to oxidize long-chain fatty acid in accordance with
 the fat content of the diet. Our results show clear sexual dimorphism in
 the variation of mitochondrial content and oxidative phosphorylation
 capacity with diet and age. The SRCD not only leads to T2DM but also
 exacerbates age-related cardiac mitochondrial defects. These observations,
 specific to male NRs, might reflect deleterious dietary-induced changes on
 their metabolism making them more prone to the cardiovascular consequences
 of aging and T2DM.

title: Data from: Lifetime cumulative incidence of dementia in a community-dwelling elderly population in Japan

description: Objective: The aim of this study is to estimate the lifetime cumulative
 incidence of dementia and its subtypes from a community-dwelling elderly
 population in Japan. Methods: A total of 1,193 community-dwelling Japanese
 individuals without dementia, aged 60 years or older, were followed-up
 prospectively for 17 years. The cumulative incidence of dementia was
 estimated based on a death- and dementia-free survival function and the
 hazard functions of dementia at each year, which were computed by using a
 Weibull proportional hazards model. The lifetime risk of dementia was
 defined as the cumulative incidence of dementia at the point in time when
 the survival probability of the population was estimated to be less than
 0.5%. Results: During the follow-up, 350 subjects experienced some type of
 dementia; among them, 191 subjects developed Alzheimer's disease (AD)
 and 117 developed vascular dementia (VaD). The lifetime risk of dementia
 was 55% (95% confidence interval [CI], 49-60%). Women had an approximately
 1.5-time greater lifetime risk of dementia than men (65% [57-72%] vs. 41%
 [33-49%]). The lifetime risks of developing AD and VaD were 42% (35-50%)
 and 16% (12-21%) in women, versus 20% (7-34%) and 18% (13-23%) in men,
 respectively. Conclusion: Lifetime risk of all dementia for Japanese
 elderly was substantial at approximately 50% or higher. This study
 suggests that the lifetime burden attributable to dementia in contemporary
 Japanese communities is immense.

title: Data from: Genetic architecture constrains exploitation of siderophore cooperation in the bacterium Burkholderia cenocepacia.

description: Abstract. Explaining how cooperation can persist in the presence of
 cheaters, exploiting the cooperative acts, is a challenge for evolutionary
 biology. Microbial systems have proved extremely useful to test
 evolutionary theory and identify mechanisms maintaining cooperation. One
 of the most widely studied system is the secretion and sharing of
 iron-scavenging siderophores by Pseudomonas bacteria, with many insights
 gained from this system now being considered as hallmarks of bacterial
 cooperation. Here, we introduce siderophore secretion by the bacterium
 Burkholderia cenocepacia H111 as a novel parallel study system, and show
 that this system behaves differently. For ornibactin, the main siderophore
 of this species, we discovered a novel mechanism of how cheating can be
 prevented. Particularly, we found that secreted ornibactin cannot be
 exploited by ornibactin-defective mutants because ornibactin receptor and
 synthesis genes are co-expressed from the same operon, such that
 disruptive mutations in synthesis genes compromise receptor availability
 required for siderophore uptake and cheating. For pyochelin, the secondary
 siderophore of this species, we found that cheating was possible, but the
 relative success of cheaters was positive frequency-dependent, thus
 diametrically opposite to the Pseudomonas and other microbial systems.
 Altogether, our results highlight that expanding our repertoire of
 microbial study systems leads to new discoveries and suggest that there is
 an enormous diversity of social interactions out there in nature, and we
 might have only looked at the tip of the iceberg so far.

title: Data from: Adaptive maternal investment in the wild? Links between maternal growth trajectory and offspring size, growth, and survival in contrasting environments

description: Life history theory predicts that investment per offspring should
 correlate negatively with the quality of environment offspring are
 anticipated to encounter; parents may use their own experience as
 juveniles to predict this environment and may modulate offspring traits
 such as growth capacity as well as initial size. We manipulated nutrient
 levels in the juvenile habitat of wild Atlantic salmon Salmo salar to
 investigate the hypothesis that the egg size maximizing juvenile growth
 and survival depends on environmental quality. We also tested whether
 offspring traits were related to parental growth trajectory. Mothers that
 grew fast when young produced more, smaller offspring than mothers that
 had grown slowly to reach the same size. Despite their size disadvantage,
 offspring of faster-growing mothers grew faster than those of slow-growing
 mothers in all environments, counter to the expectation that they would be
 competitively disadvantaged. However, they had lower relative survival in
 environments where the density of older predatory/competitor fish was
 relatively high. These links between maternal (but not paternal) growth
 trajectory and offspring survival rate were independent of egg size,
 underscoring that mothers may be adjusting egg traits other than size to
 suit the anticipated environment faced by their offspring.

title: Data from: Carotenoid pigmentation in salmon: Variation in expression at BCO2-l locus controls a key fitness trait affecting red colouration

description: Carotenoids are primarily responsible for the characteristic red flesh
 colouration of salmon. Flesh colouration is an economically and
 evolutionarily significant trait that varies inter- and
 intra-specifically, yet the underlying genetic mechanism is unknown.
 Chinook salmon (Oncorhynchus tshawytscha) represent an ideal system to
 study carotenoid variation as, unlike other salmonids, they exhibit
 extreme differences in carotenoid utilization due to genetic
 polymorphisms. Here, we crossed populations of Chinook salmon with fixed
 differences in flesh colouration (red vs. white) for a genome-wide
 association study (GWAS) to identify loci associated with pigmentation.
 Here, the beta-carotene oxygenase 2-like (BCO2-l) gene was significantly
 associated with flesh colour, with the most significant SNP explaining 66%
 of the variation in colour. BCO2 gene disruption is linked to carotenoid
 accumulation in other taxa, therefore we hypothesize that an ancestral
 mutation partially disrupting BCO2-l activity (i.e., hypomorphic mutation)
 allowed the deposition and accumulation of carotenoids within Salmonidae.
 Indeed, we found elevated transcript levels of BCO2-l in white Chinook
 salmon relative to red. The long-standing mystery of why salmon are red,
 while no other fishes are, is thus likely explained by a hypomorphic
 mutation in the proto-salmonid at the time of divergence of red-fleshed
 salmonid genera (~30 MYA).

title: Data from: Diversity in reproductive seasonality in the three-spined stickleback, Gasterosteus aculeatus

description: The annual timing of reproduction is a key life history trait having a
 large effect on fitness. Populations often vary in the timing and duration
 of reproduction to adapt to different seasonality of ecological and
 environmental variables between habitats. However, little is known about
 the molecular genetic mechanisms underlying interpopulation variation in
 reproductive seasonality. Here, we demonstrate that the three-spined
 stickleback (Gasterosteus aculeatus) can be a good model for molecular
 genetic analysis of variations in reproductive seasonality. We first
 compiled data on reproductive seasons of diverse ecotypes, covering
 marine-anadromous, lake, and stream ecotypes, of three-spined stickleback
 inhabiting a wide range of latitudes. Our analysis showed that both
 ecotype and latitude significantly contributed to variations in
 reproductive seasons. Stream ecotypes tend to start breeding earlier and
 end later than other ecotypes. Populations from lower latitudes tend to
 start breeding earlier than those from higher latitudes in all three
 ecotypes. Additionally, stream ecotypes tend to have extended breeding
 seasons at lower latitudes than at higher latitudes, leading to nearly
 year-round reproduction in the most southern stream populations. A review
 of recent progress in our understanding of the physiological mechanisms
 underlying seasonal reproduction in the three-spined stickleback indicates
 that photoperiod is an important external cue that stimulates and/or
 suppresses reproduction in this species. Taking advantage of genomic tools
 available for this species, the three-spined stickleback will be a good
 model to investigate what kinds of genes and mutations underlie variations
 in the physiological signalling pathways that regulate reproduction in
 response to photoperiod.

title: Data from: Heightened perception of competition hastens courtship

description: When animals use costly labile display or signal traits to display to the
 opposite sex, they face complex decisions regarding the degree and timing
 of their investment in separate instances of trait expression. Such
 decisions may be informed by not only the focal individual’s condition (or
 pool of available resources), but also aspects of the social environment,
 such as perceptions of same-sex competition or the quality of available
 mates. However, the relative importance of these factors to investment
 decisions remains unclear. Here we use manipulations of condition (through
 dietary nutrition), recent social environment (exposure to a silenced
 male, non-silenced male, female, or isolation), and female mating history
 (single- or multiple-male) to test how quickly male decorated crickets
 (Gryllodes sigillatus) decide to begin courting an available female. We
 find that males that were previously housed with non-silenced males
 started courting the female earlier than other males. Females only mounted
 males after courtship began. Our results suggest a strong effect of the
 perception of competition on the decision to invest resources in sexual
 signalling behaviour, and that females might exert directional selection
 on its timing.

title: Long-term movements and home range changes: rapid territory shifts in meerkats

description: 1. Territoriality and stable home ranges are a common space use pattern
 among animals. These ranges provide its inhabitants with important
 resources and thus favourable territories are associated with an increased
 fitness. While the role of territory quality and changes of territory
 ownership have often been investigated, the changes of territorial
 boundaries have been less studied. 2. Here we investigated space use
 changes in a social mammal species, applying a novel analytical approach,
 calculating long-term dissimilarity in space use using distance matrices
 based on periodic utilization distributions. This approach makes it
 possible to identify different space use patterns, which cannot be
 distinguished by only considering changes between consecutive time
 periods. 3. We analysed meerkat (Suricata suricatta) movements of a total
 of 24 different groups over a 16-year period, resulting in 134 group
 years. We then correlated the identified home range changes to life
 history events and possible environmental drivers. 4. Groups had stable
 territories for several years before they abandoned their home range
 mostly to move quickly to new areas where they again remained for several
 years. Of 26 identified sudden shifts, 22 occurred in the summer months
 and often involved distances larger than the original home range size.
 Home-range movements that were close together in time were often also
 spatially clustered and moved in a similar direction. These shifts were
 often preceded by more frequent interactions between groups, but did not
 seem to be a product of direct displacements by other groups. The
 normalized difference vegetation index (NDVI) as a measure of food
 production and social factors such as dominance changes did not correlate
 to changes. 5. Against our expectation space use changes were not
 accumulations of small changes, but more often involved long distance
 moves into unknown ranges. This means that the groups enter areas where
 they cannot profit from local knowledge. The methods used identifies
 episodes of long stability alternated by sudden changes in meerkats and in
 general provides insight into long-term space use. Our methods can be used
 to analyse long-term space use, either within or across species.

title: Predator pheromone elicits a temporally dependent non-consumptive effect in prey

description: The influence of predator cues on the behaviour of prey is well supported
 in the literature; however, a clear understanding of how predator cues
 affect prey in variable environmental conditions and over longer time
 scales is needed to better understand the underlying mechanisms. Here, we
 measure how predator odors affect herbivore colonization, abundance,
 oviposition, and plant damage across two growing seasons. The study system
 consisted of Leptinotarsa decemlineata (Colorado potato beetle) as prey,
 and the aggregation pheromone of live Podisus maculiventris (spined
 soldier bug) as the predator cue in a potato field. In 2016, the amount of
 feeding damage by early beetle colonists was lower in predator
 odor‐treated plots, reducing plant damage by 22%. Larval abundance was
 also reduced in treated plots in 2016. Beetle abundance and damage in 2017
 was similar in the treatment and control plots. Two mechanisms were
 investigated to better understand why prey response to the predator odor
 treatment weakened over the first season, including changes in predator
 odor cue strength and prey habituation. Predator odor cue strength emerged
 as a likely explanation, as dispensers, which released a synthetic
 predator pheromone over the entire season, reduced the probability of
 finding damage more consistently than the live predator treatment. These
 results suggest that temporal patterns of predator cue release and
 strength may drive prey response across the season, underscoring the
 importance of cue release‐rate and consistency in both species
 interactions and for the future application of modifying insect behaviour
 using non‐consumptive effects in agricultural systems.
