Complexity and weak integration promote the diversity of reef fish oral jaws.

Major trade-offs often manifest as axes of diversity in organismal functional systems. Overarching trade-offs may result in high trait integration and restrict the trajectory of diversification to be along a single axis. Here, we explore the diversification of the feeding mechanism in coral reef fishes to establish the role of trade-offs and complexity in a spectacular ecological radiation.

Post-meiotic mechanism of facultative parthenogenesis in gonochoristic whiptail lizard species.

Facultative parthenogenesis (FP) has historically been regarded as rare in vertebrates, but in recent years incidences have been reported in a growing list of fish, reptile, and bird species. Despite the increasing interest in the phenomenon, the underlying mechanism and evolutionary implications have remained unclear. A common finding across many incidences of FP is either a high degree of homozygosity at microsatellite loci or low levels of heterozygosity detected in next-generation sequencing data.

Assessment of Potential Accumulation of Trifluoroacetate in Terminal Lakes.

Trifluoroacetate (TFA) is the anionic form of the shortest perfluorocarboxylic acid (PFCA) and is ubiquitous in the environment at concentrations that are typically much higher than those of other PFCAs. As a stable and nonvolatile anion, it is expected to accumulate in terminal lakes in endorheic basins. This research sampled eight terminal lakes in the Western United States to determine the degree to which TFA is concentrating in these lakes and compare the data to samples collected from three of these lakes 25 years ago.

Winter Rains Support Butterfly Diversity, but Summer Monsoon Rainfall Drives Post-Monsoon Butterfly Abundance in the Arid Southwest of the US.

Butterfly populations are declining worldwide, reflecting our current global biodiversity crisis. Because butterflies are a popular and accurate indicator of insect populations, these declines reflect an even more widespread threat to insects and the food webs upon which they rely. As small ectotherms, insects have a narrow range of habitable conditions; hence, extreme fluctuations and shifts caused by climate change may increase insects' risk of extinction.

Influence of COVID-19 on the emergence of stone-tool use behavior in a population of common long-tailed macaques (Macaca fascicularis fascicularis) in Thailand.

Stone tool use is a rare behavior across nonhuman primates. Here we report the first population of common long-tailed macaques (Macaca fascicularis fascicularis) who customarily used stone tools to open rock oysters (Saccostrea forskali) on a small island along the Thai Gulf in Koh Ped (KPE), eastern Thailand. We observed this population several times during the past 10 years, but no stone-tool use behavior was observed until our survey during the coronavirus disease 2019 (COVID-19) pandemic in July 2022.

Effect of parabranchial position on ventilatory pressures in the Pacific spiny dogfish (Squalus suckleyi).

The mechanics of ventilation in elasmobranchs have been described as a two-pump system which is dependent on the generation of differential pressures between the orobranchial and parabranchial cavities. However, this general model does not take into account sources of variation in parabranchial form and function. For example, the relative pressures that drive flow in each parabranchial chamber during ventilation remain largely unexplored.

Rhesus macaque social functioning is paternally, but not maternally, inherited by sons: potential implications for autism.

Background: Quantitative autistic traits are common, heritable, and continuously distributed across the general human population. Patterns of autistic traits within families suggest that more complex mechanisms than simple Mendelian inheritance-in particular, parent of origin effects-may be involved. The ideal strategy for ascertaining parent of origin effects is by half-sibling analysis, where half-siblings share one, but not both, parents and each individual belongs to a unique combination of paternal and maternal half-siblings.

Assessing Shared Reading in Families at Risk: Does Quantity Predict Quality?

Purpose: Quantity and quality of early at-home reading shape literacy outcomes. At-home reading frequency is a common outcome measure in interventions. This single measure may not fully capture the quality of early reading interactions, such as parent and child references to print, an important contributor to language and literacy outcomes.

Increases in Trifluoroacetate Concentrations in Surface Waters over Two Decades.

Trifluoroacetate (TFA) is a persistent perfluorinated alkanoic acid anion that has many anthropogenic sources, with fluorocarbon refrigerants being a major one. After an initial burst of research in the late 1990s and early 2000s, research on this ubiquitous pollutant declined as atmospheric emissions of the precursor compounds grew rapidly. Thus, there is little contemporaneous information about the concentrations of TFA in the environment and how they have changed over time.

Ecdysteroid responses to urban heat island conditions during development of the western black widow spider (Latrodectus hesperus).

The steroid hormone 20-hydroxyecdysone (20E) controls molting in arthropods. The timing of 20E production, and subsequent developmental transitions, is influenced by a variety of environmental factors including nutrition, photoperiod, and temperature, which is particularly relevant in the face of climate change. Environmental changes, combined with rapid urbanization, and the increasing prevalence of urban heat islands (UHI) have contributed to an overall decrease in biodiversity making it critical to understand how organisms respond to elevating global temperatures.

Rexinoids Modulate Effector T Cell Expression of Mucosal Homing Markers CCR9 and α4β7 Integrin and Direct Their Migration .

Altering T cell trafficking to mucosal regions can enhance immune responses towards pathogenic infections and cancers at these sites, leading to better outcomes. All--retinoic acid (ATRA) promotes T cell migration to mucosal surfaces by inducing transcription of the mucosal-homing receptors CCR9 and α4β7 binding to retinoic acid receptors (RARs), which heterodimerize with retinoid X receptors (RXRs) to function. However, the unstable nature and toxicity of ATRA limit its use as a widespread treatment modality for mucosal diseases.

Gene flow from rhesus (Macaca mulatta) to cynomolgus macaques (M. fascicularis) and effects of introgressive hybridization on reproduction in two biomedically relevant non-human primate species.

Background: We compared the reproductive patterns of wild Indochinese and Sundaic cynomolgus macaques (Mf) exhibiting different levels of genetic admixture with rhesus macaques (Mm).

Methods: Ten adult females from each Indochinese (WHM) and Sundaic (KN/KTK) Mf populations, which exhibited 50% and 15% of Mm autosomal SNPs, were selected as focal animals. Animals were observed for 12 months, and the frequencies of sexual proceptivity, attractivity and receptivity, number of newborns, and changes in sex skin were recorded.

Population Structure of Macaca fascicularis aurea, and their Genetic Relationships with M. f. fascicularis and M. mulatta Determined by 868 RADseq-Derived Autosomal SNPs-A consideration for biomedical research.

Background: This study examined the population structure of Macaca fascicularis aurea and their genetic relationships with M. f. fascicularis and M.

Testing how different narrative perspectives achieve communication objectives and goals in online natural science videos.

Communication of science through online media has become a primary means of disseminating and connecting science with a public audience. However, online media can come in many forms and stories of scientific discovery can be told by many individuals. We tested whether the relationship of a spokesperson to the science story being told (i.

Regulatory Status of Pesticide Residues in Cannabis: Implications to Medical Use in Neurological Diseases.

Medical cannabis represents a potential route of pesticide exposure to susceptible populations. We compared the qualifying conditions for medical use and pesticide testing requirements of cannabis in 33 states and Washington, D.C.

Data assimilation of synthetic data as a novel strategy for predicting disease progression in alopecia areata.

The goal of patient-specific treatment of diseases requires a connection between clinical observations with models that are able to accurately predict the disease progression. Even when realistic models are available, it is very difficult to parameterize them and often parameter estimates that are made using early time course data prove to be highly inaccurate. Inaccuracies can cause different predictions, especially when the progression depends sensitively on the parameters.

Xenobiotic metabolism and transport in .

has emerged as a major model in biomedical and environmental toxicology. Numerous papers on toxicology and pharmacology in have been published, and this species has now been adopted by investigators in academic toxicology, pharmacology, and drug discovery labs. has also attracted the interest of governmental regulatory agencies charged with evaluating the safety of chemicals.

Secondary contact and genomic admixture between rhesus and long-tailed macaques in the Indochina Peninsula.

Understanding the process and consequences of hybridization is one of the major challenges in evolutionary biology. A growing body of literature has reported evidence of ancient hybridization events or natural hybrid zones in primates, including humans; however, we still have relatively limited knowledge about the pattern and history of admixture because there have been little studies that simultaneously achieved genome-scale analysis and a geographically wide sampling of wild populations. Our study applied double-digest restriction site-associated DNA sequencing to samples from the six localities in and around the provisional hybrid zone of rhesus and long-tailed macaques and evaluated population structure, phylogenetic relationships, demographic history, and geographic clines of morphology and allele frequencies.

An Analysis of Forensically Important Insects Associated with Human Remains in Indiana, U.S.A.

Research documenting insect colonization of human remains is limited in North America, and currently nonexistent for the American Midwest. Such research is essential for forensic entomologists to identify species of research interest in a region. In this study, we collected insects from human remains in 24 cases across Indiana from June 2016 through September 2018.

What bereaved parents want health care providers to know when their babies are stillborn: a community-based participatory study.

Background: Bereaved parents experience higher rates of depressive and post-traumatic stress symptoms after the stillbirth of a baby than after live-birth. Yet, these effects remain underreported in the literature and, consequently, insufficiently addressed in health provider education and practice. We conducted a participatory based study to explore the experiences of grieving parents during their interaction with health care providers during and after the stillbirth of a baby.

A Small Population Study on Friction Skin Ridges: Differences in Ridge Widths Between Latent and Inked Fingerprints.

Morphological changes in the width of latent fingermark ridges occur naturally over time. This could be used to examine the aging process of latents and eventually estimate time of deposition. In a crime context, it is common practice to compare a questioned (aged) fingermark with a database of known (inked) prints.

Antiviral activity of metal chelates of caffeic acid and similar compounds towards herpes simplex, VSV-Ebola pseudotyped and vaccinia viruses.

Organic compounds with a caffeoyl moiety (e.g. caffeic acid, rosmarinic acid, chicoric acid, etc.

Genetic analysis of samples from wild populations opens new perspectives on hybridization between long-tailed (Macaca fascicularis) and rhesus macaques (Macaca mulatta).

In the past decade, many researchers have published papers about hybridization between long-tailed and rhesus macaques. These previous works have proposed unidirectional gene flow with the Isthmus of Kra as the zoogeographical barrier of hybridization. However, these reports analyzed specimens of unknown origin and/or did not include specimens from Thailand, the center of the proposed area of hybridization.

Assessing Working Memory in Children: The Comprehensive Assessment Battery for Children - Working Memory (CABC-WM).

The Comprehensive Assessment Battery for Children - Working Memory (CABC-WM) is a computer-based battery designed to assess different components of working memory in young school-age children. Working memory deficits have been identified in children with language-based learning disabilities, including dyslexia and language impairment, but it is not clear whether these children exhibit deficits in subcomponents of working memory, such as visuospatial or phonological working memory. The CABC-WM is administered on a desktop computer with a touchscreen interface and was specifically developed to be engaging and motivating for children.
