Abstract
Members of the genus Oncicola Travassos, 1916 are generalist parasites able to infect a broad spectrum of carnivorous hosts, such as marsupials, procyonids, felids, and canids, and are distributed globally. Adult specimens were collected from the intestines of three white-nosed coatis (N. narica), whereas cystacanths (larval form) were found in the body cavities of two amphibian species (paratenic hosts) in localities from northern and southeastern Mexico. Morphologically, both stages were identified as O. luehei (Travassos, 1917) on the basis of the following features: trunk cylindrical, narrow anteriorly, enlarging midbody, tapering gradually to narrow posteriorly; proboscis globular with six circular rows of hooks with six hooks each, decreasing in size posteriorly; neck short with sensory papilla; tubular lemnisci long, extending to the posterior region; protonephridia dendritic type; and eight cement glands, compact with a single giant nuclei. Sequences from cytochrome c oxidase subunit 1 from mtDNA were aligned and compared with sequences available in GenBank. Phylogenetic analyses revealed that adults and cystacanths formed a clade with two other isolates identified as Oncicola sp. and O. luehei from Mexico. The intraspecific genetic divergence among the isolates was low, ranging from 0.0% to 3.0%, indicating that the two stages of the life cycle belong to the same species. The haplotype network was inferred with 11 sequences and revealed a lack of shared haplotypes between populations, suggesting a reduced recombination rate and a high pattern of genetic variation among individuals. Finally, these new records of O. luehei increase the distribution range of O. luehei on both coasts of Mexico.

Abstract
A new species of polychaete annelid, Armandia ramanamurthyi n. sp., is described from the sandy sediments off Tamil Nadu coast, Bay of Bengal, northern Indian Ocean. The major feature distinguishing A. ramanamurthyi n. sp. from other species of the genus is bearing a non-papillated anal tube and the presence of a bulbous, orbicular papilla ventrally placed at the proximal end of the anal tube. The orbicular papilla bears black pigmentation and posteriorly ends in an oblique cirrus. Additionally, Ophelina arabica Parapar, Al-Kandari, Barroso & Moreira, 2023 described from Kuwait waters is recorded for the first time in Indian waters since its original description.

Abstract

Background
Psychotic disorders are characterized by emotion regulation abnormalities that predict greater symptom severity and poor functional outcomes. However, it is unclear whether these abnormalities also occur in individuals at clinically high risk for psychosis (CHR). The current study used ecological momentary assessment (EMA) to address this question and examined the nature of abnormalities at three stages of emotion regulation (identification, selection, implementation).

Methods
Participants included 120 CHR and 59 CN who completed 1 week of EMA surveys evaluating emotional experience, emotion regulation, context, and symptoms. Multi-level models examined concurrent and time-lagged effects.

Results
CHR evidenced elevated state negative affect and abnormalities at all three stages of emotion regulation. At the identification stage (i.e., determining the need to regulate), regulatory attempts were made too frequently and with too much effort at low levels of negative affect and not frequently enough and with insufficient effort at high levels of negative affect. Selection stage abnormalities (i.e., choosing the exact strategy to attempt based on context) were characterized by increased frequency of selecting individual strategies and greater polyregulation (i.e., use of multiple strategies concurrently). Implementation stage (i.e., executing the selected strategy) abnormalities were indicated by being less effective at decreasing the intensity of negative affect from time t to t + 1.

Conclusions
It is not only heightened stress reactivity that confers risk for psychosis, but also abnormalities in applying emotion regulation strategies to control the stress response. The profile of abnormalities observed in CHR is similar to schizophrenia, suggesting treatment targets that transcend phases of psychotic illness.

Abstract

Background
The emotion regulation network (ERN) in the brain provides a framework for understanding the neuropathology of affective disorders. Although previous neuroimaging studies have investigated the neurobiological correlates of the ERN in major depressive disorder (MDD), whether patients with MDD exhibit abnormal functional connectivity (FC) patterns in the ERN and whether the abnormal FC in the ERN can serve as a therapeutic response signature remain unclear.

Methods
A large functional magnetic resonance imaging dataset comprising 709 patients with MDD and 725 healthy controls (HCs) recruited across five sites was analyzed. Using a seed-based FC approach, we first investigated the group differences in whole-brain resting-state FC of the 14 ERN seeds between participants with and without MDD. Furthermore, an independent sample (45 MDD patients) was used to evaluate the relationship between the aforementioned abnormal FC in the ERN and symptom improvement after 8 weeks of antidepressant monotherapy.

Results
Compared to the HCs, patients with MDD exhibited aberrant FC between 7 ERN seeds and several cortical and subcortical areas, including the bilateral middle temporal gyrus, bilateral occipital gyrus, right thalamus, calcarine cortex, middle frontal gyrus, and the bilateral superior temporal gyrus. In an independent sample, these aberrant FCs in the ERN were negatively correlated with the reduction rate of the HAMD17 score among MDD patients.

Conclusions
These results might extend our understanding of the neurobiological underpinnings underlying unadaptable or inflexible emotional processing in MDD patients and help to elucidate the mechanisms of therapeutic response.

Abstract

Background
Previous studies identified clusters of first-episode psychosis (FEP) patients based on cognition and premorbid adjustment. This study examined a range of socio-environmental risk factors associated with clusters of FEP, aiming a) to compare clusters of FEP and community controls using the Maudsley Environmental Risk Score for psychosis (ERS), a weighted sum of the following risks: paternal age, childhood adversities, cannabis use, and ethnic minority membership; b) to explore the putative differences in specific environmental risk factors in distinguishing within patient clusters and from controls.

Methods
A univariable general linear model (GLS) compared the ERS between 1,263 community controls and clusters derived from 802 FEP patients, namely, low (n = 223) and high-cognitive-functioning (n = 205), intermediate (n = 224) and deteriorating (n = 150), from the EU-GEI study. A multivariable GLS compared clusters and controls by different exposures included in the ERS.

Results
The ERS was higher in all clusters compared to controls, mostly in the deteriorating (β=2.8, 95% CI 2.3 3.4, η2 = 0.049) and the low-cognitive-functioning cluster (β=2.4, 95% CI 1.9 2.8, η2 = 0.049) and distinguished them from the cluster with high-cognitive-functioning. The deteriorating cluster had higher cannabis exposure (meandifference = 0.48, 95% CI 0.49 0.91) than the intermediate having identical IQ, and more people from an ethnic minority (meandifference = 0.77, 95% CI 0.24 1.29) compared to the high-cognitive-functioning cluster.

Conclusions
High exposure to environmental risk factors might result in cognitive impairment and lower-than-expected functioning in individuals at the onset of psychosis. Some patients’ trajectories involved risk factors that could be modified by tailored interventions.
“Our Own and Our Country’s Ruin”: Public Credit, War Markets, and Political Transition in the Colonial American Northeast, 1758–1768
Authors: Fifield Donovan 
Published: February 2025

Abstract
In British North America, imperial sovereignty required peripheral cooperation in public finance. However, because of limited coercive British state capacity, local colonial assemblies and town governments operated with substantial autonomy. The interests of colonial subjects did not align exactly with those of politicians and military officers in the center of British imperial authority in London. Short term success in colonial war between 1754 and 1763 required policies that incentivized colonists to buy into the imperial project. After 1758, Parliament and royal departments managed to incentivize greater provincial participation and resource allocation to the military by co-opting existing colonial merchant networks using lucrative public contracts. The contracts requested a small number of merchant firms in colonial cities take on large debts to circulate notes of credit in exchange for commissions. Merchant financiers could use these notes to pay for military expenses. The contracts promised bullion remittances from England to cover the debts, but these funds ultimately proved insufficient to cover outstanding obligations. Failures to remit led to a colonial credit crisis between 1762 and 1768 which shook colonists’ faith in the credibility of the British fiscal state in the decade leading up to the American Revolution.

AbstractLand surface temperature (LST) monitoring via Earth observation constellation will become optimized and consistent with spatiotemporal‐explicit characteristics. Besides, scientific evidence for the interaction between LST and vegetation biophysical variables remains limited through spatial large‐scale assessment and seamless long‐term tracking. This study addresses this gap by utilizing gap‐filled fine spatial resolution LST products in understanding the dynamic over the period 2000–2023 and the spatiotemporal relationship with leaf area index (LAI). Firstly, Moderate Resolution Imaging Spectroradiometer (MODIS) LST 1,000 m of both daytime and nighttime were downscaled to a finer resolution of 250 m using the Random Forest algorithm. The Whittaker algorithm was then applied to obtain gap‐free LST products due to the typical cloud cover under tropical monsoon climate. Time series decomposition of gap‐filled fine resolution LST revealed slight warming trends in daytime (0.005°C year−1), nighttime (0.036°C year−1), and mean of all‐day time (0.02°C year−1) over recent 24 years, while seasonal amplitude in daytime (−3.7°C–4.8°C) is more fluctuated than in nighttime (−2.5°C–1.9°C). Spatial correlations of monthly LSTs and LAI indicated a consistent negative correlation (R ranging from −0.717 to −0.45). These findings shed light on the quantitative relationship between vegetation LAI and LST, contributing to a more unified theoretical framework for understanding functional vegetation responses under diverse climatic conditions.

AbstractOn 21 June 2022, during the annual Geospace Environment Modeling (GEM) workshop, a panel discussion titled “Radiation Belt Loss: The Long‐Standing Debate Part II” was organized by the focus group “System Understanding of Radiation Belt Particle Dynamics.” The panel focused on unresolved questions regarding the mechanisms driving electron loss in Earth's radiation belts, discussing topics including magnetopause shadowing, outward radial transport, and wave‐particle interactions driving particle precipitation. In this commentary, we provide an overview of the outcomes of this discussion and highlight future needs to better resolve outstanding questions.

AbstractEnceladus is a target for astrobiology due to the plume ejecta measured by the Cassini spacecraft and the inferred subsurface ocean that could be the source of the geysers. Here we explore an alternative where shear heating along tiger stripe fractures produces partial melting in the ice shell and interstitial convection allows fluid to be ejected as geysers. We use an idealized two‐dimensional reactive transport model to simulate a mushy region generated by an upper‐bound estimate for the localized shear heating rate. We find that the rate of internal melting could potentially match the observed eruption rate. The composition of the liquid brine would be, however, distinct from that of the ocean, due to fractionation during partial melting. This shear heating mechanism for geyser formation could apply to Enceladus and other icy moons and has implications for our understanding of the geophysical processes and astrobiological potential of icy satellites.
Transport of Nitric Oxide in the Winter Mesosphere and Lower Thermosphere
Authors: Liu H.‐L. 
Published: February 2025

AbstractNitric oxide (NO) plays key roles both in thermospheric energetics and upper‐lower atmosphere coupling. However, mesospheric NO in the polar night region has often been underestimated in whole atmosphere models, and the exact causes are not well understood. Recent high‐resolution (HR) WACCM‐X simulations show significant increase in NO in the polar night, and our analysis reveals distinct differences in the vertical transport between the HR and coarse resolution (CR) simulations: The residual mean vertical wind in the mesosphere and lower thermosphere (MLT) region displays mesoscale flow channels that are strong and alternate between upward and downward directions in the former, with large net downward transport over the polar region. In the latter it is much weaker and even upward over large latitude ranges. Moreover, the resolved waves in the HR simulations induce downward eddy transport of NO in the MLT much stronger than the parameterized diffusion in CR simulations.
Feedbacks Between Fjord Circulation, Mélange Melt, and the Subglacial Discharge Plume at Kangerlussuaq Glacier, East Greenland

Published: February 2025

AbstractIn recent decades, the Greenland ice sheet has been losing ice and contributing substantially to global sea level rise. Approximately half of this recent loss is due to glacier acceleration, increasing the calving of icebergs into the ocean. This process has been linked with increased ocean heat content on the continental shelf, yet the pathways delivering this heat into Greenland's fjords and its interactions with fjord‐scale processes modulating glacier ice loss are still unclear. In this study, we use a series of numerical ocean model configurations to examine feedbacks between ocean circulation, subglacial discharge, submarine glacier melt, and ice mélange in Kangerlussuaq Fjord—a major fjord system where Greenland's third‐largest glacier terminates. We find that subglacial discharge is a major control on ocean properties, increasing the up‐fjord advection of deep warm water more than 10‐fold over fjords without discharge and modulating ocean temperature on the continental shelf near the fjord mouth. Further, discharge‐driven upwelling increases ice mélange melt 3‐fold, revealing that subglacial discharge is an important control on mélange melt, particularly in the summer when submarine glacier melt and subsequent glacier retreat is highest. These results suggest that subglacial plume activity contributes to the strong correlation between mélange thickness and retreat noted in previous studies and may contribute to extensive future retreat at Kangerlussuaq Glacier.

AbstractTropical cyclones (TCs) often undergo track turning when moving over the ocean. However, the influence of track turning on TC‐ocean interactions remains little explored. This study systematically investigates sea surface temperature (SST) cooling and TC intensification during TC track‐turning stages in global TC‐active basins during 1998–2022. Globally, turning TCs induce stronger SST cooling than straight‐moving TCs (e.g., −1.53°C vs. −1.08°C for categories 1–2), expand cooling area by 40%–110%, and greatly reduce cooling asymmetry for left‐turning (right‐turning) TCs in the Northern (Southern) Hemisphere. The translation speed of turning TCs is 1.5 m s−1 slower compared to straight‐moving TCs. Numerical experiments demonstrate that the enhanced cooling is attributed to the combined effect of track turning and accompanying slow translation speed. The enhanced cooling effectively suppresses storm intensification of turning TCs. The intensification rate for straight‐moving versus turning TCs is 2.98 versus 0.06 m s−1 per 24 hr for categories 1–2. As turning angle increases, cooling magnitude increases and intensification rate decreases. The probability of rapid intensification for turning TCs is about one‐third lower than that for straight‐moving TCs. Consequently, TCs with smaller turning angles are more likely to develop into intense TCs. Operational forecast models underforecast turning angles of turning TCs and thus overforecast TC intensity with forecast errors increasing with turning angle. This study demonstrates that TC track‐turning stages play a crucial role in modulating TC intensification via an oceanic pathway, highlighting that improving track turning forecast will contribute to enhancing TC intensity forecast accuracy.

AbstractExperimental soil heating experiments have found a consistent increase in soil‐surface CO2 emissions (Fs), but inconsistent soil organic carbon (SOC) responses. Interpretation of heating effects is complicated by spatial heterogeneity and soil moisture, nitrogen availability, and microbial and plant responses. Here we applied a mechanistic ecosystem model to interpret heating impacts on a California forest subjected to 1 m deep, 4°C heating. The model accurately simulated control‐plot CO2 fluxes, SOC stocks, fine root biomass, soil moisture, and soil temperature, and the observed increases in Fs and decreases in fine root biomass. We show that a complex suite of interactions can lead to a consistent increase in Fs (∼17%) over the 5‐year study period, with very small changes in SOC stocks (<1%). Modeled increases in leaf water stress from soil drying reduced GPP and NPP. The resulting reduction in leaf and fine root allocation increased fine root litter inputs to the soil and reduced root exudation. Soil heating led to about a 50% larger increase in root autotrophic respiration than in heterotrophic respiration, with the heating effect on both these fluxes decreasing over the simulation period. Increased heterotrophic respiration led to increased soil N availability and plant N uptake. These heating responses are mechanistically linked, of magnitudes that can affect ecosystem dynamics, and long‐term observations of them are rarely made. Therefore, we conclude that a coupled observational and mechanistic modeling framework is needed to interpret manipulation experiments, and to improve projections of climate change impacts on terrestrial ecosystem carbon dynamics.

Abstract
Increasing lines of evidence suggest cerebral overgrowth in autism spectrum disorder (ASD) children in early life, but few studies have examined the effect of ASD common genetic variants on brain volumes in a general paediatric population. This study examined the association between ASD polygenic risk score (PRS) and volumes of the frontal, temporal, parietal, occipital, fronto-temporal and parieto-occipital lobes in 273 term-born infants of European ancestry in the developing Human Connectome Project. ASD PRS was positively associated with frontal (β = 0.027, p

FDR
= 0.04) and fronto-temporal (β = 0.024, p

FDR
= 0.01) volumes, but negatively with parietal (β = −0.037, p

FDR
= 0.04) and parieto-occipital (β = −0.033, p

FDR
= 0.01) volumes. This preliminary result suggests the potential involvement of ASD common genetic variants in early structural variations linked to ASD.
