title: Erdos Straus conjecture solution

description: This paper presents a formal resolution of the Erdős–Straus Conjecture, which asserts that for every integer n ≥ 2, the expression 4/n can be decomposed into the sum of three positive unit fractions. Through a combination of modular arithmetic, algebraic identities, and constructive decomposition methods, the solution generalizes across all integer domains. The proof includes symbolic verification and computational validation up to 10^9, confirming the conjecture’s universality. This work offers a conclusive step in resolving a classical unsolved problem in number theory.

title: Data from: Submicroscopic Plasmodium falciparum gametocyte densities frequently result in mosquito infection.

description: Submicroscopic Plasmodium falciparum gametocytemia (&lt;5,000
 gametocytes/mL) is common and may result in mosquito infection. We
 assessed the relation between gametocyte density and mosquito infection
 under experimental and field conditions using real-time quantitative
 nucleic acid sequence-based amplification (QT-NASBA) for gametocyte
 quantification. Serial dilutions of NF54 P. falciparum gametocytes showed
 a positive association between gametocyte density and the proportion of
 infected mosquitoes (beta=6.1; 95% confidence interval [CI], 2.7-9.6;
 P=0.001). Successful infection became unlikely below an estimated density
 of 250-300 gametocytes/mL. In the field, blood samples of 100 naturally
 infected children showed a positive association between gametocyte density
 and oocyst counts in mosquitoes (beta=0.38; 95% CI, 0.14-0.61; P=0.002).
 The relative contribution to malaria transmission was similar for carriers
 with submicroscopic and microscopic gametocytemia. Our results show that
 transmission occurs efficiently at submicroscopic gametocyte densities and
 that carriers harboring submicroscopic gametocytemia constitute a
 considerable proportion of the human infectious reservoir.

title: Data from: Coexistence and the niche in a nurse-cactus interaction: is cyclic dynamics justified?

description: 1. The interaction between the nurse plant Larrea tridentata and the cacti
 Cylindropuntia leptocaulis is thought to follow cyclical-replacement
 dynamics. However, the required changing nature of their interaction, from
 facilitation to competition, has not been investigated through their full
 life cycle. 2. In order to test the hypothesised cyclical dynamics, we
 compared the demography of four sub-populations (LA = Larrea associated to
 Cylindropuntia; CA = Cylindropuntia associated to Larrea, LS = solitary
 Larrea; CS = solitary Cylindropuntia) in the Mapimí Biosphere Reserve,
 Mexico, over the period 2008-2015. This allowed us to compare their
 demography at varying levels of the generally low and unpredictable
 limiting resource, water. Given the protection afforded to C. leptocaulis
 seedlings by L. tridentata and their presumed increasingly competitive
 effect on L. tridentata, which would justify the expectation of cyclic
 replacement dynamics, we expected to find a zero or positive per capita
 rate of population growth (r≥0) in CA and LS, and a negative one in CS and
 LA. 3. The overall r over the study period was close to equilibrium (r=0)
 for both LA and LS, with no significant difference between them. In
 contrast, and as expected, r of CA was consistently and significantly
 larger than that for CS. In both species, λ (=er) was positively
 correlated with annual rainfall with no significant difference between LA
 and LS and a significant difference between CA and CS in this
 relationship. L. tridentata can exist alone and coexist with C.
 leptocaulis across the levels of precipitation experienced at the study
 site, while C. leptocaulis cannot persist in the absence of L. tridentata.
 The cyclical dynamics of replacement does not occur in this system and,
 given the static nature of the evidence on which the original conclusion
 was based, it is unlikely to exist as a general rule across the species’
 geographic range. 4. Synthesis: Our findings stress the importance of
 elucidating the demographic mechanisms that allow species competing for a
 common limiting resource to coexist when the resource varies temporally,
 and expose the difficulty of identifying a species’ ecological niche in
 the absence of detailed, long-term demographic information.

title: Data from: Water for African elephants (Loxodonta Africana): faecal microbial loads affect use of artificial waterholes

description: In semi-arid protected areas artificial waterholes ensure that water is
 locally available to animals for extended periods. However, artificial
 waterholes may limit animal movement, which contributes towards habitat
 deterioration. Challenges of artificial water provisioning worsen in the
 presence of ecosystem engineers like African elephants Loxodonta africana,
 capable of transforming environments. Camera traps were used to monitor
 elephant visitation at 21 artificial waterholes in the Kruger National
 Park, South Africa. We also assessed if water quality parameters
 influenced elephant preference for certain waterholes. There were no
 significant correlations between elephant abundance and water
 physicochemical properties. However, there was a strong negative
 correlation between elephant abundance and levels of Escherichia coli in
 water. Our findings suggest that elephants avoid drinking water with high
 levels of faecal microbial loads. Whereas most studies addressing animal
 management in protected areas consider waterholes as homogeneous units, we
 posit that water quality could also determine local landscape use and
 movement patterns of key species like elephants, a finding with relevant
 implications in reserve management practices.

title: Data from: Dietary changes in predators and scavengers in a nocturnally illuminated riparian ecosystem

description: Aquatic and terrestrial ecosystems are linked by fluxes of carbon and
 nutrients in riparian areas. Processes that alter these fluxes may
 therefore change the diet and composition of consumer communities. We used
 stable carbon isotope (δ13C) analyses to test whether the increased
 abundance of aquatic prey observed in another study led to a dietary shift
 in riparian consumers in areas illuminated by artificial light at night
 (ALAN). We measured the contribution of aquatic-derived carbon to diets in
 riparian arthropods in experimentally lit and unlit sites along an
 agricultural drainage ditch in northern Germany. The δ13C signature of the
 spider Pachygnatha clercki (Tetragnathidae) was 0.7‰ lower in the
 ALAN-illuminated site in summer, indicating a greater assimilation of
 aquatic prey. Bayesian mixing models also supported higher intake of
 aquatic prey under ALAN in summer (34% versus 21%). In contrast, isotopic
 signatures for P. clercki (0.3‰) and Pardosa prativaga (0.7‰) indicated a
 preference for terrestrial prey in the illuminated site in summer.
 Terrestrial prey intake increased in spring for P. clerckii under ALAN
 (from 70% to 74%) and in spring and autumn for P. prativaga (from 68% to
 77% and from 67% to 72%) and Opiliones (from 68% to 72%; 68% to 75%). This
 was despite most of the available prey (up to 80%) being aquatic in
 origin. We conclude that ALAN changed the diet of riparian secondary
 consumers by increasing the density of both aquatic and terrestrial prey.
 Dietary changes were species- and season-specific, indicating that the
 effects of ALAN may interact with phenology and feeding strategy. Because
 streetlights can occur in high density near freshwaters, ALAN may have
 widespread effects on aquatic-terrestrial ecosystem linkages.

title: Data from: A mathematical model of cocoa bean fermentation

description: Cocoa bean fermentation relies on the sequential activation of several
 microbial populations, triggering a temporal pattern of biochemical
 transformations. Understanding this complex process is of tremendous
 importance as it is known to form the precursors of the resulting
 chocolate's flavor and taste. At the same time, cocoa bean
 fermentation is one of the least controlled processes in the food
 industry. Here, a quantitative model of cocoa bean fermentation is
 constructed based on available microbiological and biochemical knowledge.
 The model is formulated as a system of coupled ordinary differential
 equations with two distinct types of state variables: (1) Metabolite
 concentrations of glucose, fructose, ethanol, lactic acid and acetic acid,
 and (2) Population sizes of yeast, lactic acid bacteria and acetic acid
 bacteria. We demonstrate that the model can quantitatively describe
 existing fermentation time series and that the estimated parameters,
 obtained by a Bayesian framework, can be used to extract and interpret
 differences in environmental conditions. The proposed model is a valuable
 tool towards a mechanistic understanding of this complex biochemical
 process, and can serve as a starting point for hypothesis testing of new
 systemic adjustments. In addition to providing the first quantitative
 mathematical model of cocoa bean fermentation, the purpose of our
 investigation is to show how differences in estimated parameter values for
 two experiments allow us to deduce differences in experimental conditions.

title: Data from: Phylogeography of the arid shrub Atraphaxis frutescens (Polygonaceae) in northwestern China: evidence from cpDNA sequences

description: Climatic fluctuations during the Pleistocene are usually considered as a
 significant factor in shaping intraspecific genetic variation and
 influencing demographic histories. To well-understand these processes in
 desert northwest China, we selected arid adapted Atraphaxis frutescens as
 the study species. Two cpDNA regions (psbK-psbI, psbB-psbH) were sequenced
 in 272 individuals from 33 natural populations across the range of this
 shrub, and 10 haplotypes were identified. It was found to contain high
 levels of total gene diversity (H T = 0.858), and low levels of
 within-population diversity (H S = 0.092). Analysis of molecular variance
 (AMOVA) indicates that genetic differentiation primarily occurs among
 groups of populations. Based on BEAST (Bayesian Evolutionary Analysis
 Sampling Trees) analysis, we suggest that intraspecific differentiation of
 the species, resulting from isolated populations, accompanied enhanced
 desertification during the middle and late Pleistocene. The expansion of
 the Gurbantunggut and Kumtag deserts in this area appears to have
 triggered divergence among populations of the western, central, and
 eastern portions of the region and shaped genetic differentiation among
 them. Two possible independent glacial refugia were predicted, the Ili
 Valley and the northern Junggar Basin. Extensive development of arid
 habitats (desert margin and arid piedmont grassland) coupled with a more
 equable climate because the early Holocene are factors likely to have
 generated recent expansion of A. frutescens.

title: Data from: Transgenerational plasticity of reproduction depends on rate of warming across generations

description: Predicting the impacts of climate change to biological systems requires an
 understanding of the ability for species to acclimate to the projected
 environmental change through phenotypic plasticity. Determining the
 effects of higher temperatures on individual performance is made more
 complex by the potential for environmental conditions experienced in
 previous and current generations to independently affect phenotypic
 responses to high temperatures. We used a model coral reef fish
 (Acanthochromis polyacanthus) to investigate the influence of thermal
 conditions experienced by two generations on reproductive output and the
 quality of offspring produced by adults. We found that more gradual
 warming over two generations, +1.5 °C in the first generation and then
 +3.0 °C in the second generation, resulted in greater plasticity of
 reproductive attributes, compared to fish that experienced the same
 increase in one generation. Reproduction ceased at the projected future
 summer temperature (31.5 °C) when fish experienced +3.0 °C for two
 generations. Additionally, we found that transgenerational plasticity to
 +1.5 °C induced full restoration of thermally affected reproductive and
 offspring attributes, which was not possible with developmental plasticity
 alone. Our results suggest that transgenerational effects differ depending
 on the absolute thermal change and in which life stage the thermal change
 is experienced.

title: Data from: Madagascar Flatidae (Hemiptera, Fulgoromorpha): state-of-the-art and research challenges

description: The paper provides a historical review of the research on Flatidae in
 Madagascar and indicates future prospects. While the first two species of
 Madagascar Flatidae were described by Guérin-Méneville (1844), it was
 Signoret (1860) who made the first real attempt to enhance our knowledge
 of the Hemiptera fauna of Madagascar by describing several additional
 species. Over the following century and a half, several investigators have
 turned their attention to this group of insects, with the final number of
 species recorded for the island reaching 76. Despite this long history of
 research , it is evident that much still remains to be done. Detailed
 taxonomic research will allow the natural history of Madgascar and changes
 in the biological diversity of its endemic ecosystems to be better
 understood. This paper should be considered as an introduction to a
 complex study on the systematics and phylogeny of worldwide Flatidae
 planthoppers.

title: Data from: Habitat features and long-distance dispersal modify the use of social information by a long-distance migratory bird

description: 1. The processes by which individuals select breeding sites have important
 consequences for individual tness as well as population- and
 community-dynamics. Although there is increasing evidence that many animal
 species use information acquired from conspecics to assess the suitability
 of potential breeding sites, little is known about how the use of this
 social information is modified by biotic and abiotic conditions. 2. We
 used an automated playback experiment to simulate two types of social
 information, post-breeding public information and pre-breeding location
 cues, to determine the relative importance of these cues for breeding site
 selection by a migratory songbird, the American redstart (Setophaga
 ruticilla). In addition, we used stable hydrogen isotopes to determine the
 dispersal status of individuals that responded to our experimental
 treatments and quantify whether long-distance dispersers use different
 social cues to select breeding sites compared to philopatric individuals.
 3. We found that points that received pre-breeding location cue treatments
 were signi cantly more likely to be settled by redstarts than control
 points that received no playback. However, we found no evidence the
 redstarts used post-breeding public information gathered during one season
 to select breeding sites the following year. Breeding site habitat
 structure was also a strong predictor of settlement probability,
 indicating that redstarts modi ed the use of social information based on
 habitat cues. Furthermore, stable hydrogen isotope signatures from
 individuals that responded to location cue treatments suggest that
 long-distance dispersers may rely more heavily on these cues than local
 recruits. 4. Collectively, these results indicate that redstarts use
 multiple sources of information to select breeding sites, which could
 buffer individuals from selecting suboptimal sites when they breed in
 unfamiliar locations or when habitat quality becomes decoupled from social
 cues.
