The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These enable users to calculate temporal trends biodiversity within amongst using a broad range of metrics. is being developed as community-led open-source time series. Our goal accelerate facilitate quantitative analysis patterns the Anthropocene.The 8,777,413 abundance records, from consistently sampled for minimum 2 years, which need not necessarily be consecutive. In...
Abstract The discovery of multi-species synchronous spawning scleractinian corals on the Great Barrier Reef in 1980s stimulated an extraordinary effort to document times other parts globe. Unfortunately, most these data remain unpublished which limits our understanding regional and global reproductive patterns. Coral Spawning Database (CSD) collates much disparate into a single place. CSD includes 6178 observations (3085 were unpublished) time or day for over 300 species 61 genera from 101...
ABSTRACT Motivation Here, we make available a second version of the BioTIME database, which compiles records abundance estimates for species in sample events ecological assemblages through time. The updated expands 1.0 database by doubling number studies and includes substantial additional curation to taxonomic accuracy records, as well metadata. Moreover, now provide an R package (BioTIMEr) facilitate use database. Main Types Variables Included is composed one main data table containing 11...
Variation in predation risk is a major driver of ecological and evolutionary change, and, turn, geographical variation behaviour. While rarely constant natural populations, the extent to which shapes individual behaviour wild populations remains unclear. Here, we investigated differences reproductive 16 Trinidadian guppy related it observed predator biomass each population experienced. Our results show that high heterogeneity linked behavioural diversification. Increased within-population...
Dispersal is critical to population persistence, colonization and connectivity which are all components of invasive success. While individual propensity disperse varies within populations, the underlying mechanisms promoting dispersal remain unclear. Collectively, influenced by environment phenotype. Here we investigated in Trinidadian guppy, Poecilia reticulata, related variation behaviour phenotype social/environmental conditions. Namely, addressed effect sex ratio (social/environmental...
Sexual selection theory assumes that maximizing fitness is the ultimate goal in every mating decision. Fitness can be maximized directly by increasing number of offspring (direct benefits) or indirectly offspring's lifetime reproductive success (indirect benefits). Whereas there considerable evidence literature for influence decisions on direct benefits, indirect benefits have been more elusive. Here, we review variables made females freshwater fish and how these affect their directly, as...
The observation that females mate multiply when males provide nothing but sperm - which sexual selection theory suggests is unlikely to be limiting continues puzzle evolutionary biologists. Here we test the hypothesis multiple mating prevalent under such circumstances because it enhances female fitness. We do this by allowing Trinidadian guppies with either a single male or males, and then tracking consequences of these matings across two generations.Overall, mated produced 67% more F2...
Abstract Early social conditions are vital for the establishment of future interactions. Less, however, is known about how differences in early contribute to process individual recognition and subsequently decision associating exploring behaviours. In this study, we address gap Trinidadian guppy Poecilia reticulata test prediction that fish would show a higher tendency recognize associate with individuals similar phenotype. This was tested by comparing likelihood association latency explore...
Females that invest adaptively in their offspring are predicted to channel more resources the sex will be at an advantage prevailing environmental conditions. Here, we report, for first time, female Trinidadian guppy, Poecilia reticulata, respond reproductively distinct ways when faced with differences operational ratio. We show females assigned a female-biased ratio produce larger male than environment which males predominate. Given link between size birth and fitness, marked reproductive...
Abstract Polyandry has the potential to affect distribution of phenotypes and shape direction sexual selection. Here, we explore this using Trinidadian guppies as a model system ask whether polyandry leads directional and/or diversifying selection male phenotypic traits. In study, compare diversity offspring from multiply singly sired broods. To quantify diversity, first combine traits multivariate methods, then take dispersion individuals in space our measure diversity. We show that, when...
Abstract Early experience is known to be important in the development of mating behaviour. The behavioural and chemical stimuli obtained by observing adults interacting are thought operate as template which young acquire ability sexually display when appropriate. But, while importance early social interactions for behaviour well accepted, how deprivation at different onto‐genetic phases contributes this effect poorly understood. Here, we address gap asking ontogenetic (before or after 6 wk)...
Cutaneous relief analysis is crucial in the development of new skincare products, as well evaluation dermatological treatments. The can be performed by qualitative or quantitative methods. We propose a algorithm to detect wrinkles and quantify skin roughness image processing from dermatoscope.A clinical study was carried out with 33 research participants, images were collected dermatoscope PRIMOS equipment for wrinkle at two different times: Day 0 (D0) 45 days (D45) after use dermocosmetic...
Abstract Mothers are expected to use environmental cues modify maternal investment optimize their fitness. However, when the environment varies unpredictably, may not be an accurate proxy of future conditions. Under such circumstances, selection favors a diversifying strategy. While there is evidence that becoming more uncertain, extent which mothers able respond this unpredictability generally unknown. In study, we test hypothesis Daphnia magna increase variance in response unpredictable...
The evolution of life history traits is regulated by energy expenditure, which is, in turn, governed temperature. forecasted increase temperature variability expected to impose greater stress organisms, turn influencing the balance expenditure and consequently responses. Here we examine how increased affects responses predation. Individuals reared under constant temperatures responded different levels predation risk as appropriate: namely, producing number neonates smaller sizes reducing...
The guppy (Poecilia reticulata) is a successful invasive species. It also species that mates multiply; previous studies have demonstrated this strategy carries fitness benefits. Guppies are routinely introduced to tanks and troughs in regions outside their native range for mosquito-control purposes, often spread beyond these initial confines into natural water bodies with negative ecological consequences. Here, using mesocosm set up resembles the containers which single guppies typically...
Scleractinian corals are colonial animals with a range of life-history strategies, making up diverse species assemblages that define coral reefs. We tagged and tracked ~30 colonies from each 11 during seven trips spanning 6 years (2009-2015) to measure their vital rates competitive interactions on the reef crest at Trimodal Reef, Lizard Island, Australia. Pairs were chosen five growth forms in which one pair was locally rare (R) other common (C). The sampled massive (Goniastrea pectinata [R]...
Abstract Sexual selection theory suggests that males need to constantly reappraise their mating decisions take account of the presence and phenotypes rivals. Here we examine this expectation by asking: (i) If a rival influences male behaviour; (ii) How important is attractiveness (absolute attractiveness) in shaping (iii) does male's comparison his (relative influence decisions. Using Trinidadian guppy, species which female mate choice (based on males’ attractive traits) plays an role...
Predation is the main cause of mortality during early life stages. The ability to avoid and evade potential threats is, therefore, favoured evolve stages life. It also these that process familiarization occurs. has long been recognized associating with familiar individuals confers antipredator benefits. Yet gaps in our knowledge remain about how predator evasion affected by social experience In this study, we test hypothesis acquired improves escape responses. Using guppy Poecilia reticulata...
Abstract While most introduced species fail to become invasive, those that succeed are a major threat global biodiversity. To improve the management of invasive species, predictive understanding invasion risk is needed. There strong evidence success linked specific traits and it well recognised phenotypic trait heterogeneity population viability. However, effects population‐level traits, contribution success, remain poorly addressed in biology. Here, we address this gap by quantifying...
