title: Reproductive success and mortality of male and female Daphnia at different sex ratios

description: This dataset contains data from Daphnia sexual reproduction
 experiments described in the paper: “Galimov YR, Haag CR,
 Tukhbatullin AR, Tchabovsky AV 2021. Sex ratio effects
 on reproductive success of male and female Daphnia. Journal of
 Evolutionary Ecology ”.  We compared reproductive
 success of male and female Daphnia in experimental populations
 with sex ratios varying from one male per 81 females to one male per one
 female. In males, reproductive success strongly and monotonically
 decreased with decreasing number of females per male. In females, in
 contrast, mating success and reproductive success were reduced only at the
 most female-biased sex ratio (1:81), when many females remained unmated
 and unfertilized, and then again at equal sex ratios, probably due to
 negative effects of high density or stress induced by numerous males. Our
 results suggest that mating competition and the opportunity for sexual
 selection may exist not only in males but, at least periodically, also in
 females.

title: A rodent herbivore reduces its predation risk through ecosystem engineering

description: Predator-prey interactions are ubiquitous and powerful forces structuring
 ecological communities [1, 2, 3]. Habitat complexity has been
 shown to be particularly important in regulating the strength of
 predator-prey interactions [4, 5]. It is now relatively
 well known that changes in habitat structure can alter the patterns and
 efficacy of predatory and anti-predatory behaviors of interacting
 predators and prey [3, 4, 6]. Nevertheless, little is known about
 the consequences of engineering activity by species on their own predation
 risk, despite of the fact that many ecosystem engineers themselves face
 pervasive predation risk in natural ecosystems. With a
 combination of field surveys and manipulative experiments, we
 evaluated how habitat modification by Brandt’s
 voles influences predation risk from avian predators
 (shrikes) in a steppe grassland, Inner Mongolian, China. We found that
 voles actively modify habitat structure by cutting down a large,
 unpalatable grass species in the presence of shrikes, an effect that
 disappeared when these avian predators were excluded experimentally. Such
 damage activities of rodents dramatically decreased the volume of
 unpalatable grasses, which in turn, reduced visitations by shrikes and
 thus the mortality rate of voles. Our study documented that
 herbivorous prey, when acting as ecosystem engineers, can indirectly
 reduce their own predation risk by modifying habitat structure. Given the
 pervasive of predation risk faced by consumers, and the ability of many
 consumers to alter the habitat structure in which they live, the interplay
 between predation risk and ecosystem engineering may be an important
 mechanism in driving the structure and dynamics of natural communities.

title: Do natural enemies mediate conspecific negative distance- and density-dependence of trees? A meta-analysis of exclusion experiments

description: Conspecific negative distance- and density-dependence is believed to be
 one of the most important mechanisms controlling forest community assembly
 and species diversity globally. Plant pathogens, and insect and mammalian
 herbivores, are the most common natural enemy types that have been
 implicated in this phenomenon, but their general effects at different
 plant life stages are still unclear. Here, we conduct a meta-analysis of
 studies that involved robust manipulative experiments, using fungicides,
 insecticides, or exclosures, to assess the contributions of different
 natural enemy types to distance- and density-dependent effects at seed and
 seedling stages. We found that conspecific negative distance- and
 density-dependence was more common at the seedling stage. Only 30% of
 studies showed significant conspecific negative distance- and
 density-dependence. Among those studies, applying fungicides significantly
 reduced the effect of conspecific negative distance -dependent mortality.
 Excluding large mammals reduced the effect of conspecifics, but with only
 marginal significance (p &lt; 0.1). Our study confirms that plant
 pathogens have a significant impact on distance -dependent mortality and
 suggests that the impacts of herbivores on seedlings have been
 understudied. At the seed stage, large and small mammals, respectively,
 appear to weaken and enhance negative conspecific distance-dependent
 mortality. Future research should identify specific agents of mortality,
 investigate the interactions among different enemy types, and assess how
 global change may affect natural enemies and thus influence the strength
 of conspecific distance- and density-dependence.

title: Selection experiment on guppy ornamental traits

description: Female preferences for male ornamental traits can arise from indirect
 benefits, such as increased attractiveness or better viability of
 progeny, but empirical evidence for such benefits is
 inconsistent. Artificial selection offers a powerful way to investigate
 indirect effects of male ornaments. Here, we selected for the area of
 orange spots on male guppies, a trait subject to female preferences in our
 population, in replicated up- and down-selected lines. We found a
 significant direct response to selection, and a correlated response in
 female preferences, with females from down-selected lines showing less
 interest in more orange males. Nevertheless, up-selected males sired more
 offspring in direct competition with low-selected males, irrespective of
 female origin. We did not find a significantly correlated
 response to selection among any other fitness correlates we measured. Our
 results imply that female preferences for orange spots can lead to
 increased reproductive success of their sons, with no effect on general
 viability of progeny. Furthermore, while we demonstrate that female
 preferences may evolve via linkage disequilibrium with the preferred
 trait, the potential for runaway selection by positive feedback may be
 constrained by the lack of corresponding linkage with male reproductive
 competitiveness.
description: Data was selected during a 6 generation selection experiment in
 which guppy males (circa 25 per generation) were selected for large vs.
 small total area of their carotenoid (orange) spots (4 independent lines
 per selection direction). This was a mass selection setup, with 25
 randomly chosen females from the respecvtive line assigned to the next
 generation of selection. In the last generation of selection we took
 several morphological and bahavioural measures as well as performed tests
 of female sexual preferences and arranged mating trial to test any fitness
 advantage of males from the opposite selection regimes. All methods and
 results are described in the article: "What do orange spots reveal
 about male (and female) guppies? A test using correlated responses to
 selection", which has been accepted for publication in
 Evolution.

title: The paradox of food production, consumption, poverty and malnutrition in Tanzania

description: Background: There have been claims amongst nutrition stakeholders in
 Tanzania that the food basket regions are leading in stunting prevalence.
 However, we could not find evidence that combines food production and
 stunting levels to substantiate this claim. Therefore, this study aims to
 compare data of stunting, food production and consumption at
 administrative regions in Tanzania Mainland. Methods: The study used an
 ecological study design to show the relationship between stunting,
 poverty, and food production and consumption across administrative regions
 in Tanzania. The study used data from three national wide surveys:
 2017/2018 Household Budget Survey (HBS), Tanzania National Nutrition
 Survey (TNNS) 2018 and Agriculture Statistics for Food Security report
 2018/2019. Results: The study showed that there is a positive relationship
 between the prevalence of stunting and food production (r=0.43, p=0.03)
 while there is a negative relationship between stunting and the level of
 both the average monthly household consumption expenditure (r = -0.48, p =
 0.01) and average monthly household food consumption expenditure (r =
 -0.509, p = 0.01). It was further found that some regions which have
 higher levels of stunting such as Njombe have the lowest level of basic
 need poverty. Conclusion: The study found a positive relationship between
 food production and the prevalence of stunting using data across regions
 in Mainland Tanzania. This is an indication that regional food security
 may not entail nutrition security hence a call for more advocacy on
 nutrition-sensitive agriculture.
description: This is an ecological study design using secondary data compiled
 from three sources: Tanzania Household Budget Survey (HBS) 2017/2018,
 Tanzania National Nutrition Survey (TNNS 2018) and Agriculture Statistics
 for Food Security report 2018/2019. Both HBS and TNNS are national-wise
 cross-sectional data organized by the Ministry of Finance and Planning and
 Ministry of Health respectively while Agriculture Statistics for Food
 Security report 2018/2019 was prepared by the Ministry of
 Agriculture. The data used Poverty, Average Food
 Consumption in TZS, Average Non Food Consumption in TZS and Average
 Monthly Consumption in TZS Data from HBS 2017/18, Total Food Production,
 Non-Cereal Food Production, Cereal Food Production from Agriculture
 Statistics for Food Security report 2018/2019 and Stunting Data from TNNS
 2018. Excel and Stata were the software used to show
 the relationship between this variables.

title: Phenotypic convergence in a natural Daphnia population acclimated to low temperature

description: Fluidity of a given membrane decreases at lower ambient temperatures,
 whereas it rises at increasing temperatures, which is achieved through
 changes in membrane lipid composition. In consistence with homeoviscous
 adaptation theory, lower temperatures result in increased tissue
 concentrations of polyunsaturated fatty acids (PUFAs) in D. magna,
 suggesting a higher PUFA requirement at lower temperatures. However, so
 far homeoviscous adaptation has been suggested for single or
 geographically separated Daphnia genotypes only. Here we investigated
 changes in relative fatty acid (FA) tissue concentrations in response to a
 lower temperature (15°C) within a D. magna population. We determined
 juvenile growth rates (JGR) and FA patterns of 14 genotypes, that were
 grown on Chlamydomonas klinobasis at 15°C and 20°C. We report significant
 differences of JGR and the relative body content of various FAs between
 genotypes at either temperature and between temperatures. Based on slopes
 of reaction norms, we found genotype-specific changes in FA profiles
 between temperatures suggesting that genotypes have different strategies
 to cope with changing temperatures. In a hierarchical clustering analysis
 we grouped genotypes according to differences in direction and magnitude
 of changes in relative FA content, which resulted in three clusters of
 genotypes following different patterns of changes in FA composition. These
 patterns suggest a lower importance of the PUFA eicosapentaenoic acid
 (EPA, C20:5ω3) than previously assumed. We calculated an unsaturation
 index (UI) as a proxy for membrane fluidity at 15°C, and we neither found
 significant differences for this UI nor for fitness, measured as JGR,
 between the three genotype clusters. We conclude that these three genotype
 clusters represent different physiological solutions to temperature
 changes by altering the relative share of different FAs, but that their
 phenotypes converge with respect to membrane fluidity and JGR. These
 clusters will be subjected to different degrees of PUFA-limitation when
 sharing the same diet.

title: A new model of forelimb ecomorphology for predicting the ancient habitats of fossil turtles

description: Various morphological proxies have been used to infer habitat preferences
 among fossil turtles and their early ancestors, but most are tightly
 linked to phylogeny, thereby minimizing their predictive power. One
 particularly widely used model incorporates linear measurements of the
 forelimb (humerus + ulna + manus) but, in addition to the issue of
 phylogenetic correlation, it does not estimate the likelihood of habitat
 assignment. Here, we introduce a new model that uses intramanual
 measurements (digit III metacarpal + non-ungual phalanges + ungual) to
 statistically estimate habitat likelihood, and that has greater predictive
 strength than prior estimators. Application of the model supports the
 hypothesis that stem-turtles were primarily terrestrial in nature, and
 recovers the nanhsiungchelyid Basilemys (a fossil crown-group turtle) as
 having lived primarily on land, despite some prior claims to the contrary.

title: Data from: Strategic pheromone signalling by mate searching females of the sexually cannibalistic spider Argiope bruennichi

description: Reproduction often requires finding a mating partner. To this end, females
 of many arthropods advertise their presence to searching males via
 volatile chemical signals. Such pheromones are considered low-cost
 signals, although this notion is based on little evidence and has recently
 been challenged. Even when utilizing comparatively low-cost signals,
 females should signal as little as possible to minimize costs while still
 ensuring mate attraction. Here we test the strategic-signalling hypothesis
 using Argiope bruennichi. In this orb-weaving spider, egg maturation
 commences with adult moult and females that do not attract a male in time
 will lay a large batch of unfertilized eggs approximately three weeks
 after maturation. Using GC-MS analyses, we show that virgin females
 enhance their signalling effort, i.e. pheromone quantity per unit body
 weight, with increasing age and approaching oviposition. We further
 demonstrate that pheromone release is condition dependent, suggesting the
 occurrence of physiological costs. Mate choice assays revealed that
 pheromone quantity is the only predictor of female attractiveness for
 males. In support of the strategic- signalling hypothesis, pheromone
 signals by female A. bruennichi become stronger with increased need as
 well as body weight, and might thus also qualify as an honest signal of
 female quality.

title: Data to accompany: Rapid body color change provides lizards with facultative crypsis in the eyes of their avian predators

description: Color change serves many antipredator functions and may allow animals to
 better match environments or disrupt outlines to prevent detection. Rapid
 color change could potentially provide camouflage to animals that
 frequently move among microhabitats. Determining the adaptiveness of
 whole-animal rapid color changes in natural habitats with respect to
 predator visual systems would greatly broaden our fundamental
 understanding of the evolution of rapid color change. We tested whether
 whole-body color change provides water anoles (Anolis aquaticus) with
 camouflage against avian predators, and whether these rapid changes allow
 them to shift between environment matching and edge disruption. We
 manipulated A. aquaticus placement in natural microhabitats and used
 digital image analysis to quantify color matching, pattern matching, and
 edge disruption produced by microhabitat-induced color change. Color
 change reduced lizard detectability to predators in microhabitat-specific
 ways. Environment matching was favored when lizards were in solid-colored
 microhabitats, regardless of exposure to predators. Edge disruption was
 instead induced by high exposure and varied by body region. We provide the
 first evidence that rapid color change permits a tetrapod to flexibly
 employ the most optimal camouflaging strategy by form (e.g., color
 matching vs. edge disruption) to minimize detection in the eyes of its
 predators.

title: Large contribution of woody plant expansion to recent vegetative greening of the Northern Great Plains

description: Aim: Extensive portions of high-latitude grasslands worldwide have
 recently experienced increased vegetative productivity (i.e., greening)
 and have undergone a rapid transition towards woody plant dominance via
 the process of woody plant expansion (WPE). This raises the underlying
 question: To what degree are WPE and greening spatiotemporally linked?
 Given that these vegetative changes are predicted to continue, we seek to
 understand how recent changes in vegetation extent and productivity have
 interacted under recent climate change and anthropogenic disturbance to
 provide insights surrounding the future trajectory of temperate grasslands
 broadly. Location: Northern Great Plains (NGP), North America Taxon: Woody
 plants Methods: Greening was measured as the significant increase in three
 metrics between 2000 and 2019: leaf area index (LAI), annual maximum
 normalized difference vegetative index (NDVI), and annual mean NDVI. WPE
 was measured as the significant proportional increase in percent tree
 cover change between 2000 and 2019 in grasslands. We then examine these
 variables across a host of 26 potential driving variables. Results: We
 show that average proportional greening increased by 0.2-1.3% yr -1
 (depending on metric), and proportional WPE increased by 6.9% yr -1 since
 2000 across the NGP. Both changes are largely driven by the absence of
 wildfire and changing climate. Furthermore, WPE was spatially coherent and
 positively associated with a large component of recent greening, as
 revealed by their coupling across 34.1-40.6% of grassland area and as
 evidenced by the 9.7-19.7% of the variability in greening explained by
 WPE. Main conclusions: WPE and greening are spatiotemporally coupled
 across large portions of the NGP. Under continued climate change and
 wildfire suppression, WPE and greening are likely to continue across large
 swathes of grasslands globally. Furthermore, our results show that using a
 single greening metric may be insufficient to capture the large-scale
 vegetative changes such as the expansion of woody vegetation.
