Adults hold a broad range of beliefs about intellectual ability. Key examples include beliefs about its malleability, its distribution in the population, whether high levels of it ("brilliance") are necessary for success, its origins, and its responsiveness to intervention. Here, we examined the structure and motivational significance of this network of consequential beliefs in a sample of elementary school-age children (5- to 11-year-olds, = 231; 116 girls, 112 boys, three gender nonbinary children; predominantly White and Asian children from relatively high-income backgrounds).

Polymorphic short insertions and deletions (INDELs ≤ 50 bp) are abundant, although less common than single nucleotide polymorphisms (SNPs). Evidence from model organisms shows INDELs to be more strongly influenced by purifying selection than SNPs. Partly for this reason, INDELs are rarely used as markers for demographic processes or to detect divergent selection.

Studying complexes of cryptic or pseudocryptic species opens new horizons for the understanding of speciation processes, an important yet vague issue for the digeneans. We investigated a hemiuroidean trematode across a wide geographic range including the northern European seas (White, Barents, and Pechora), East Siberian Sea, and the Pacific Northwest (Sea of Okhotsk and Sea of Japan). The goals were to explore the genetic diversity within through mitochondrial ( and genes) and ribosomal (ITS1, ITS2, 28S rDNA) marker sequences, to study morphometry of maritae, and to revise the life cycle data.

Urbanization as a major driver of global change modifies biodiversity patterns and the abundance and interactions among species or functional species groups. For example, urbanization can negatively impact both predator-prey and mutualistic relationships. However, empirical studies on how urbanization modifies biotic, particularly multitrophic, interactions are still limited.

Understanding the relative contributions of environmental, behavioural and social factors to reproductive success is crucial for predicting population dynamics of seabirds. However, these factors are often studied in isolation, limiting our ability to evaluate their combined influence. This study investigates how marine environmental variables, foraging behaviour and social factors (divorce), influence reproductive success in little penguins () over 13 breeding seasons.

Parasitic plants are a diverse and unique polyphyletic assemblage of flowering plants that survive by obtaining resources via direct vascular connections to a host plant. Ecologically important in their native ecosystems, these typically cryptic plants remain understudied and fundamental knowledge of the biology, ecology, and evolution of most species is lacking. This gap limits our understanding of ecosystems and conservation management.

Food web architecture and trophic interactions between organisms can be studied using ratios of naturally occurring stable isotopes of carbon (C/C) and nitrogen (N/N). Most studies, however, focused on free-living organisms, but recently, there has been growing interest in understanding trophic interactions of parasites. The crustacean ectoparasite is a well-studied parasite of freshwater teleost fish, which has low host specificity and a cosmopolitan distribution.

Modification and deterioration of old-growth forests by industrial forestry have seriously threatened species diversity worldwide. The loss of natural habitats increases the concentration of circulating glucocorticoids and incurs chronic stress in animals, influencing the immune system, growth, survival, and lifespan of animals inhabiting such areas. In this study, we tested whether great tit () nestlings grown in old-growth unmanaged coniferous forests have longer telomeres than great tit nestlings developing in young managed coniferous forests.

Trade-offs between food acquisition and predator avoidance shape the landscape-scale movements of herbivores. These movements create landscape features, such as game trails, which are paths that animals use repeatedly to traverse the landscape. As such, these trails integrate behavioral trade-offs over space and time.

The role of trait evolution in shaping the functional and ecological diversity of tropical forests remains poorly understood. Analyses of trait variation as a function of evolutionary history and environmental variables should reveal the drivers of species distributions, as well as generate insights valuable to conservation. Here, we focus on the Dipterocarpaceae, the key plant family underpinning the hyperdiversity of South-East Asian tropical forest canopies and of major conservation concern due to over-exploitation for timber, cultivation, and climate change.

Purpose: While several studies demonstrate an association between reproductive coercion or a lack of reproductive autonomy and decreased mental health in women, little is known about potential mental health impacts when women are denied prescription contraceptives. The aim of this research was to explore associations between prescription contraceptive denial and perceived ease of future access to contraception, and self-assessed mental health.

Patients And Methods: Polish women (N=424) completed an anonymous online survey with demographic questions; perceived stress (PSS-10), state anxiety (STAI-X1), and depression (CESD-R) assessments, and contraceptive access questions.

The ability of viruses to emerge in new species is influenced by aspects of host biology and ecology, with some taxa harbouring a high diversity and abundance of viruses. However, how these factors shape virus diversity at the ecosystem scale is often unclear. To better understand the pattern and determinants of viral diversity within an ecosystem, and to describe the novel avian viruses infecting an individual avian community, we performed a metagenomic snapshot of the virome from the entire avian community on remote Pukenui/Anchor Island in Aotearoa New Zealand.

This paper develops the methodological concept of river co-learning arenas (RCAs) and explores their potential to strengthen innovative grassroots river initiatives, enliven river commons, regenerate river ecologies, and foster greater socio-ecological justice. The integrity of river systems has been threatened in profound ways over the last century. Pollution, damming, canalisation, and water grabbing are some examples of pressures threatening the entwined lifeworlds of human and non-human communities that depend on riverine systems.
