How Needs-Supplies Fit Processes With Teachers, Peers, and Parents Relate to Youth Outcomes: A Theoretical and Methodological Extension of Self-Determination Theory.

According to self-determination theory (SDT), relationships that support the needs for autonomy, competence, and relatedness are essential to youth development. It is yet unknown whether adolescents differ in what constitutes "optimal" supplies of support. This research proposes methodological extensions to analyze how the degree of fit or misfit between needs versus supplies in support (i.

Environmental DNA recovers fish composition turnover of the coral reefs of West Indian Ocean islands.

Islands have been used as model systems to study ecological and evolutionary processes, and they provide an ideal set-up for validating new biodiversity monitoring methods. The application of environmental DNA metabarcoding for monitoring marine biodiversity requires an understanding of the spatial scale of the eDNA signal, which is best tested in island systems. Here, we investigated the variation in Actinopterygii and Elasmobranchii species composition recovered from eDNA metabarcoding along a gradient of distance-to-reef in four of the five French Scattered Islands in the Western Indian Ocean.

Divergent responses of pelagic and benthic fish body-size structure to remoteness and protection from humans.

Animal body-size variation influences multiple processes in marine ecosystems, but habitat heterogeneity has prevented a comprehensive assessment of size across pelagic (midwater) and benthic (seabed) systems along anthropic gradients. In this work, we derive fish size indicators from 17,411 stereo baited-video deployments to test for differences between pelagic and benthic responses to remoteness from human pressures and effectiveness of marine protected areas (MPAs). From records of 823,849 individual fish, we report divergent responses between systems, with pelagic size structure more profoundly eroded near human markets than benthic size structure, signifying greater vulnerability of pelagic systems to human pressure.

Cross-ocean patterns and processes in fish biodiversity on coral reefs through the lens of eDNA metabarcoding.

Increasing speed and magnitude of global change threaten the world's biodiversity and particularly coral reef fishes. A better understanding of large-scale patterns and processes on coral reefs is essential to prevent fish biodiversity decline but it requires new monitoring approaches. Here, we use environmental DNA metabarcoding to reconstruct well-known patterns of fish biodiversity on coral reefs and uncover hidden patterns on these highly diverse and threatened ecosystems.

How many replicates to accurately estimate fish biodiversity using environmental DNA on coral reefs?

Quantifying fish species diversity in rich tropical marine environments remains challenging. Environmental DNA (eDNA) metabarcoding is a promising tool to face this challenge through the filtering, amplification, and sequencing of DNA traces from water samples. However, because eDNA concentration is low in marine environments, the reliability of eDNA to detect species diversity can be limited.

Revisiting the Effects of Gender Diversity in Small Groups on Divergent Thinking: A Large-Scale Study Using Synchronous Electronic Brainstorming.

Numerous studies have examined the effects of gender diversity in groups on creative performance, and no clear effect has been identified. Findings depend on situational cues making gender diversity more or less salient in groups. A large-scale study on two cohorts ( = 2,261) was conducted among business students to examine the impact of the gender diversity in small groups on divergent thinking in an idea-generation task performed by synchronous electronic brainstorming.

Use of environmental DNA in assessment of fish functional and phylogenetic diversity.

Assessing the impact of global changes and protection effectiveness is a key step in monitoring marine fishes. Most traditional census methods are demanding or destructive. Nondisturbing and nonlethal approaches based on video and environmental DNA are alternatives to underwater visual census or fishing.

Environmental DNA metabarcoding reveals and unpacks a biodiversity conservation paradox in Mediterranean marine reserves.

Although we are currently experiencing worldwide biodiversity loss, local species richness does not always decline under anthropogenic pressure. This conservation paradox may also apply in protected areas but has not yet received conclusive evidence in marine ecosystems. Here, we survey fish assemblages in six Mediterranean no-take reserves and their adjacent fishing grounds using environmental DNA (eDNA) while controlling for environmental conditions.

Detection of the elusive Dwarf sperm whale () using environmental DNA at Malpelo island (Eastern Pacific, Colombia).

Monitoring large marine mammals is challenging due to their low abundances in general, an ability to move over large distances and wide geographical range sizes.The distribution of the pygmy () and dwarf () sperm whales is informed by relatively rare sightings, which does not permit accurate estimates of their distribution ranges. Hence, their conservation status has long remained Data Deficient (DD) in the Red list of the International Union for Conservation of Nature (IUCN), which prevent appropriate conservation measures.

Accumulation curves of environmental DNA sequences predict coastal fish diversity in the coral triangle.

Environmental DNA (eDNA) has the potential to provide more comprehensive biodiversity assessments, particularly for vertebrates in species-rich regions. However, this method requires the completeness of a reference database (i.e.

Correction: Remote reefs and seamounts are the last refuges for marine predators across the Indo-Pacific.

Remote reefs and seamounts are the last refuges for marine predators across the Indo-Pacific.

Since the 1950s, industrial fisheries have expanded globally, as fishing vessels are required to travel further afield for fishing opportunities. Technological advancements and fishery subsidies have granted ever-increasing access to populations of sharks, tunas, billfishes, and other predators. Wilderness refuges, defined here as areas beyond the detectable range of human influence, are therefore increasingly rare.

Isolation and no-entry marine reserves mitigate anthropogenic impacts on grey reef shark behavior.

Reef sharks are vulnerable predators experiencing severe population declines mainly due to overexploitation. However, beyond direct exploitation, human activities can produce indirect or sub-lethal effects such as behavioral alterations. Such alterations are well known for terrestrial fauna but poorly documented for marine species.

Environmental DNA illuminates the dark diversity of sharks.

In the era of "Anthropocene defaunation," large species are often no longer detected in habitats where they formerly occurred. However, it is unclear whether this apparent missing, or "dark," diversity of megafauna results from local species extirpations or from failure to detect elusive remaining individuals. We find that despite two orders of magnitude less sampling effort, environmental DNA (eDNA) detects 44% more shark species than traditional underwater visual censuses and baited videos across the New Caledonian archipelago (south-western Pacific).

Sex Differences in Language Across Early Childhood: Family Socioeconomic Status does not Impact Boys and Girls Equally.

Child sex and family socioeconomic status (SES) have been repeatedly identified as a source of inter-individual variation in language development; yet their interactions have rarely been explored. While sex differences are the focus of a renewed interest concerning emerging language skills, data remain scarce and are not consistent across preschool years. The questions of whether family SES impacts boys and girls equally, as well as of the consistency of these differences throughout early childhood, remain open.

[Age-prospective memory-paradox: explanatory hypotheses].

Prospective memory is a complex cognitive function requiring to remember a planned action. For example, this function is particularly important for elderly people to remember taking medication at the appropriate time. The comparison of the performance of old and young peoples on different prospective memory tasks led to two contradictory results, a configuration that has been dubbed "age-prospective memory-paradox".

Working memory in children predicts performance on a gambling task.

The authors investigated whether working memory (WM) plays a significant role in the development of decision making in children, operationalized by the Children's Gambling Task (CGT). A total of 105 children aged 6-7, 8-9, and 10-11 years old carried out the CGT. Children aged 6-7 years old were found to have a lower performance than older children, which shows that the CGT is sensitive to participant's age.

What happens after graduation? Outcomes, employment, and recommendations of recent junior/community college graduates with and without disabilities.

Purpose: The objective was to compare employment status of junior/community college graduates with and without disabilities.

Methods: We compared post-graduation outcomes of 182 graduates with and 1304 without disabilities from career/technical and pre-university programs from three junior/community colleges. Findings for graduates who had registered for disability related services from their school and those who had not were examined separately.

[Urban asthma and habitat].

This study examines in urban area the housing conditions in asthma patients who called a first-aid association of doctors (SOS Médecins) and their relationships to symptoms. The patient population is compared with the non asthmatic population who called SOS Medecins during the same period. During the first six months of 1989, among 102,791 calls, 701 were related to acute asthma symptoms, and 100 non asthma patients were sorted at random as a control group.

[Asthma, urban atmospheric pollution and the weather].

The aim of this study, which was carried out in an urban environment, was to research in to a possible relationship between temporal variations in the level of atmospheric pollution in the centre of Paris, compared to the frequency of acute dyspnoeic crises in which asthmatic patients had requested the emergency service (SOS Médecins). This study began in the first half of 1989; during this period there were 701 cases of acute asthma recorded within the Paris city boundary by "SOS Médecins". The pollutants recorded were sulphur dioxide (SO2), an index of black smoke (FN), oxides of nitrogen (NOx), ozone (O3) and soluble sulphate particles (SO4).
