title: A Macroeconomic Analysis of Factors Influencing the Performance of Mutual Funds in Morocco

description: The excel includes panel data analysis to explore these relationships over the period from 2010 to 2023, using annual data, resulting in a total of 3,052 observations. To provide a comprehensive analysis, the study categorizes mutual funds into four types: long-term bonds (1,358 observations), equity funds (868 observations), money market funds (462 observations), and short-term bonds (364 observations) collectively representing the mutual fund sector in Morocco. This categorization enables a detailed assessment of how macroeconomic factors influence each type of mutual fund differently.

Data for mutual fund performance is sourced from DataStream. The performance measures, including the Sharpe Ratio, Treynor Ratio, and Jensen’s Alpha, are calculated based on extracted Net Asset Values (NAV), weekly returns, market benchmarks, and computed beta values. The macroeconomic variables such as inflation, exchange rate, GDP growth, money supply, imports, foreign direct investment (FDI), and political stability are obtained from the International Monetary Fund (IMF) and the World Bank’s World Development Indicators (WDI) database.

·       The Sharpe Ratio quantifies excess return per unit of total risk calculated as    where 𝑅𝑝 is the portfolio return, 𝑅𝑓 is the risk-free rate, and 𝜎𝑝 is the standard deviation of portfolio returns.

·       The Treynor Ratio measures excess return per unit of systematic risk, given by   with 𝛽𝑝 representing the portfolio’s beta relative to the market.

·       Jensen’s Alpha captures excess return over the expected return under the Capital Asset Pricing Model (CAPM), computed as   where 𝑅𝑚 is the market return.

title: Data from: Understanding cryptic introgression and mixed ancestry of Red Junglefowl in India

description: Red Junglefowl (RJF), the wild progenitor of modern day chicken (DC), are
 believed to be in genetic endangerment due to introgression of domestic
 genes through opportunistic matings with domestic or feral chickens.
 Previous studies from India reported rare hybridization of RJF in wild,
 however, RJF population structure,pattern of gene flow and their admixture
 with DC populations are poorly understood at the landscape level. We
 conducted this study with the large sample size, covering the predicted
 natural distribution range of RJF in India. We documented strong evidence
 of directional gene flow from DC to free ranging wild RJF, with the
 Northeast RJF population exhibiting the most genetic variants at nuclear
 & mitochondrial genome and indicated of being the ancestral
 population from which early radiation would have occurred. The results
 provide evidence that landscape features do not act as a barrier to gene
 flow and the distribution pattern could not be explored due to physical
 sharing or exchange of wild birds in the past when forests were continuous
 across RJF range in India.

title: Data from: Contributions of feather microstructure to eider down insulation properties

description: Insulation is an essential component of nest structure that helps provide
 incubation requirements for birds. Many species of waterfowl breed in high
 latitudes where rapid heat loss can necessitate a high energetic input
 from parents and use down feathers to line their nests. Common eider
 Somateria mollissima nest down has exceptional insulating properties but
 the microstructural mechanisms behind the feather properties have not been
 thoroughly examined. Here, we hypothesized that insulating properties of
 nest down are correlated to down feather (plumule) microstructure. We
 tested the thermal efficiency (fill power) and cohesion of plumules from
 nests of two Icelandic colonies of wild common eiders and compared them to
 properties of plumules of wild greylag goose Anser anser. We then used
 electron microscopy to examine the morphological basis of feather
 insulating properties. We found that greylag goose down has higher fill
 power (i.e. traps more air) but much lower cohesion (i.e. less prone to
 stick together) compared to common eider down. These differences were
 related to interspecific variation in feather microstructure. Down
 cohesion increased with the number of barbule microstructures (prongs)
 that create strong points of contact among feathers. Eider down feathers
 also had longer barbules than greylag goose down feathers, likely
 increasing their air-trapping capacity. Feather properties of these two
 species might reflect the demands of their contrasting evolutionary
 history. In greylag goose, a temperate, terrestrial species, plumule
 microstructure may optimize heat trapping. In common eiders, a diving duck
 that nests in arctic and subarctic waters, plumule structure may have
 evolved to maximize cohesion over thermal insulation, which would both
 reduce buoyancy during their foraging dives and enable nest down to
 withstand strong arctic winds.

title: Data from: Bees at war: interspecific battles and nest usurpation in stingless bees

description: We provide the first evidence for inter-specific warfare in bees, a
 spectacular natural phenomenon that involves a series of aerial battles
 and leads to thousands of fatalities from both attacking and defending
 colonies. Through molecular analyses of fights at a study hive of the
 Australian stingless bee, Tetragonula carbonaria, we revealed an attack
 launched by a related species, T. hockingsi, which has only recently
 extended its habitat into southeastern Queensland. Following a succession
 of attacks by the same T. hockingsi colony over a four-month period, the
 defending T. carbonaria colony was defeated and the hive usurped, with the
 winning colony installing a new queen. We complemented our direct
 observations with a longitudinal study of over 260 hives over five years,
 and found interspecies hive changes, which were likely to be usurpation
 events, occurring in 46 Tetragonula hives over this period. We discuss how
 fighting swarms and hive usurpation fit with theoretical predictions on
 the evolution of fatal fighting, and highlight the many unexplained
 features of these battles that warrant further study.

title: Data from: Cost of dispersal in a social mammal: body mass loss and increased stress

description: Dispersal is a key process influencing the dynamics of socially and
 spatially structured populations. Dispersal success is determined by the
 state of individuals at emigration and the costs incurred after
 emigration. However, quantification of such costs is often difficult, due
 to logistical constraints of following wide-ranging individuals. We
 investigated the effects of dispersal on individual body mass and stress
 hormone levels in a cooperative breeder, the meerkat (Suricata suricatta).
 We measured body mass and faecal glucocorticoid metabolite (fGCM)
 concentrations from 95 dispersing females in 65 coalitions through the
 entire dispersal process. Females that successfully settled lost body
 mass, while females that did not settle but returned to their natal group
 after a short period of time did not. Furthermore, dispersing females had
 higher fGCM levels than resident females, and this was especially
 pronounced during the later stages of dispersal. By adding information on
 the transient stage of dispersal and by comparing dispersers that
 successfully settled to dispersers that returned to their natal group, we
 expand on previous studies focusing on the earlier stages of dispersal. We
 propose that body mass and stress hormone levels are good indicators to
 investigate dispersal costs, as these traits often play an important role
 in mediating the effects of the environment on other life-history events
 and individual fitness.

title: Data from: Pulsed food resources, but not forest cover, determines lifetime reproductive success in a forest-dwelling rodent

description: 1. The relative contributions of habitat and food availability on fitness
 may provide evidence for key habitat features needed to safeguard
 population persistence. However, defining habitat quality for a species
 can be a complex task, especially if knowledge on the relationship between
 individual performance and habitat quality is lacking. 2. Here, we
 determined the relative importance of availability of suitable forest
 habitat, body mass, and food from masting tree species on female lifetime
 reproductive success (LRS) of Siberian flying squirrels (Pteromys volans).
 3. We calculated LRS of 500 female flying squirrels based on a 22
 year-long longitudinal data set of two populations from western Finland.
 We assessed with generalised additive models the potential effects of
 availability of suitable habitat and cumulative lifetime availability of
 food from masting tree species on female LRS, longevity and fecundity. On
 a reduced dataset, we evaluated the importance of female winter body mass
 and conducted a piecewise path analysis to determine how variables were
 connected. 4. According to generalised additive models female longevity,
 fecundity and LRS were mainly determined by variation in cumulative
 lifetime availability of food from masting alder and birch. Instead,
 habitat and body mass had smaller role. The path analysis indicated that
 lifetime food availability had direct effect on longevity and fecundity,
 and these had equal effect on LRS at both study sites. 5. Our results on
 LRS shows that the occurrence of tree masting events during a flying
 squirrel female’s lifetime have profoundly larger effect on lifetime
 reproductive success than the cover of suitable forest habitat.
 Furthermore, this study emphasises the importance of both fecundity and
 longevity, and the indirect effects of food availability via those
 components, as determinants of lifetime fitness of female flying
 squirrels.

title: Data from: Extensive variation in sperm morphology in a frog with no sperm competition

description: Background: Recent comparative studies of several taxa have found that
 within-species variation in sperm size decreases with increasing levels of
 sperm competition, suggesting that male-male gamete competition selects
 for an optimal sperm phenotype. Previous studies of intraspecific sperm
 length variation have all involved internal fertilizers where some other
 factors—e.g., sperm storage and sperm movement along the walls of the
 female’s reproductive tract—probably also influence and reduce sperm size
 variation. Thus external fertilizers, where those factors are absent,
 might be expected to exhibit even more variation when there is little or
 no sperm competition. To test that idea, we studied the sperm morphology
 of a North American chorus frog, the spring peeper (Pseudacris crucifer),
 a species in which males encounter little or no sperm competition.
 Results: As expected, sperm size was highly variable in the spring peeper,
 largely due to variation in flagellum length within and among individual
 males, among populations and between mitochondrial lineages in
 southwestern Ontario. In addition, a large proportion of spermatozoa in
 all males was abnormal in such a way that the ability of abnormal
 spermatozoa to fertilize was probably compromised. There were no
 differences in the frequencies of abnormalities among populations or
 mitochondrial lineages. Conclusions: In the absence of sperm competition,
 we suggest that genetic drift has probably played a role in the generation
 of diversity in sperm morphology in this species, potentially resulting in
 the observed differences among populations. Such interpopulation
 difference in sperm morphology might be expected to increase the degree of
 reproductive isolation between populations even before other isolating
 mechanisms evolve.

title: Data from: Plant interactions as biotic drivers of plasticity in leaf litter traits and decomposability of Quercus petraea

description: The importance of plant litter traits and decomposability for nutrient
 cycling processes and plant community dynamics through plant-litter-soil
 feedbacks has been largely emphasized. However, the role of biotic
 interactions as drivers of intraspecific variability in litter traits
 remains surprisingly little studied. In this study, we used a large-scale,
 multi-site network of long-term tree removal experiments manipulating the
 abundance of a foundation tree species, i.e. Quercus petraea, to assess
 how plant interactions control intraspecific variation in oak leaf litter
 traits and decomposability. We studied 19 plots across eight experimental
 sites covering a large gradient of oak abundance, stand age and local
 abiotic context. Oak leaf litter quality strongly declined with tree
 removal in early forest successional stage. Litter became poorer in
 nutrients such as N and Mg and richer in secondary metabolites such as
 lignin and condensed tannins. This in turn slowed its decomposition.
 Importantly, litter N loss switched from N release to N immobilization.
 Variance partitioning indicated that oak abundance explained as much
 variation in oak leaf litter traits as oak age and twice as much as soil
 inherent fertility. Confirmatory path analysis revealed that the decline
 of oak leaf litter quality induced by tree removal was most likely driven
 by a shift in understory plant species composition. Plasticity of oak leaf
 litter traits to the shortage of nutrient supply related to the
 development of understory plants competitors with higher nutrient capture
 and retention ability could potentially explain this response pattern. Our
 data also give consistent but weaker support that the decline of oak leaf
 litter quality could be driven by alleviated competition for light among
 canopy trees and subsequent enhanced crown exposure to light. Overall, our
 study provides evidence that biotic factors such as plant interactions are
 major drivers of plasticity in leaf litter traits and decomposability.
 This finding contributes to the emerging view that phenotypic plasticity
 is fundamentally related to biotic interactions for sessile organisms,
 especially for long-lived and large plant species such as trees. Taking
 this source of functional diversity into account could help us to better
 understand plant community dynamics and ecological processes in
 terrestrial ecosystems.

title: Data from: Survival to independence in relation to pre-fledging development and latitude in songbirds across the globe

description: Species differ strongly in their life histories, including the probability
 of survival. Annual adult survival was investigated extensively in the
 past, whereas juvenile survival, and especially survival to independence,
 received much less attention. Yet, they are critical for our understanding
 of population demography and life-history evolution. We investigated
 post-fledging survival to independence (i.e. survival upon leaving the
 nest until nutritional independence) in 74 species of passerine birds
 worldwide based on 100 population level estimates extracted from published
 literature. Our comparative analyses revealed that survival to
 independence increased with the length of nestling period and relative
 fledging mass (ratio of fledging mass to adult body mass). At the same
 time, species with higher nest predation rates had shorter nestling
 periods and lower relative fledging mass. Thus, we identify an important
 trade-off in life history strategies: staying longer in the nest may
 improve post-fledging survival due to enhanced flight ability and sensory
 functions, but at the cost of a longer exposure to nest predators and
 increased mortality due to nest predation. Additionally, post-fledging
 survival to independence did not differ between species from the northern
 temperate zone vs species from the tropics and southern hemisphere.
 However, analyses of post-fledging survival curves suggest that 1) daily
 survival rates are not constant and improve quickly upon leaving the nest,
 and 2) species in the tropics and southern hemisphere have higher daily
 post-fledging survival rates than northern temperate species.
 Nevertheless, due to the accumulation of mortality risk during their much
 longer periods of post-fledging care, overall survival until independence
 is comparable across latitudes. Obtaining high-quality demographic data
 across latitudes to evaluate the generality of these findings and
 mechanisms underlying them should be a research priority.
