title: Behavioural and trophic niche partitioning between two sympatric marsh terns

description: Understanding how ecologically similar species coexist in shared environments is a central question in community ecology, particularly in systems where closely related species breed sympatrically and exploit overlapping resources. In such systems, differences in behaviour, especially in foraging decisions, may play a key role in reducing interspecific competition. Marsh terns of the genus Chlidonias provide an excellent model for examining fine-scale niche differentiation, yet comparative data on diet and foraging behaviour in sympatric populations remain scarce. We examined whether two sympatrically breeding species, the White-winged Tern Chlidonias leucopterus and the Black Tern Chlidonias niger, differ in chick diet composition and behavioural patterns of foraging habitat use by adults in the near-natural Bug River valley (eastern Poland). Chick provisioning was quantified from video recordings at nests and adult foraging behaviour was assessed using transect scans near mixed colonies. Diet composition differed between species and varied with brood size. White-winged Terns delivered proportionally more terrestrial prey, particularly Orthoptera, whereas Black Terns provided more fish and showed stronger associations with aquatic prey. Foraging patterns exhibited a pronounced species by habitat interaction, with White-winged Terns foraging mainly over meadows and Black Terns over oxbows and the river channel. The close correspondence between foraging habitats and chick diet composition indicates that species-specific foraging decisions by adults directly shape offspring provisioning. These results demonstrate multidimensional niche partitioning across dietary and spatial axes, which likely reduces interspecific competition and facilitates stable coexistence in mixed colonies, highlighting behaviour as a key mechanism underlying coexistence between sympatric marsh terns, where the White-winged Tern occurs near the western margin of its range and the Black Tern occupies the range core.

description: This dataset provides raw and inverted Very Low Frequency Electromagnetic (VLF-EM) data acquired via an drone-mounted GEM Systems GSM-90AVU UAV-VLF platform in Utqiaġvik, Alaska. The primary objective of the survey was to map subsurface conductive structures and characterize permafrost dynamics. The dataset includes raw electromagnetic field measurements along 7 survey line L0~L6 (In-phase and Quadrature):



Stations used: NPM (21.4 kHz), NLK (24.8 kHz).

Latitude (N/S): 71.3268°N to 71.3315°N

Longitude (E/W): -156.6031° W to -156.5863° W


Inversion results were generated using MARE2DEM. Each inversion file corresponds to a specific flight line (e.g., `F1_L0.xyz`).

title: Data from: The earliest bird-line archosaurs and the assembly of the dinosaur body plan

description: The relationship between dinosaurs and other reptiles is well established, but the sequence of acquisition of dinosaurian features has been obscured by the scarcity of fossils with transitional morphologies. The closest extinct relatives of dinosaurs either have highly derived morphologies or are known from poorly preserved or incomplete material. Here we describe one of the stratigraphically lowest and phylogenetically earliest members of the avian stem lineage (Avemetatarsalia), Teleocrater rhadinus gen. et sp. nov., from the Middle Triassic epoch. The anatomy of T. rhadinus provides key information that unites several enigmatic taxa from across Pangaea into a previously unrecognized clade, Aphanosauria. This clade is the sister taxon of Ornithodira (pterosaurs and birds) and shortens the ghost lineage inferred at the base of Avemetatarsalia. We demonstrate that several anatomical features long thought to characterize Dinosauria and dinosauriforms evolved much earlier, soon after the bird–crocodylian split, and that the earliest avemetatarsalians retained the crocodylian-like ankle morphology and hindlimb proportions of stem archosaurs and early pseudosuchians. Early avemetatarsalians were substantially more species-rich, widely geographically distributed and morphologically diverse than previously recognized. Moreover, several early dinosauromorphs that were previously used as models to understand dinosaur origins may represent specialized forms rather than the ancestral avemetatarsalian morphology.

title: A Novel Hypothesis on Immunomodulatory Components in Tick Saliva and Their Potential Role in Alpha-Gal Syndrome

description: Alpha-gal syndrome (AGS) is an IgE-mediated hypersensitivity to galactose-alpha-1,3-galactose (alpha-gal), primarily triggered by tick bites. This conceptual paper proposes a hypothesis positing that a putative salivary component capable of binding alpha-gal, potentially involved in alpha-gal handling in ticks, may contribute to immunosuppression in humans, eliciting delayed anaphylaxis upon red meat ingestion. We incorporate precise scientific details, including immunosuppressive molecules like prostaglandin E₂ (PGE₂), glycosylated proteins, and glycolipids in tick saliva that skew immunity toward Th2 responses and facilitate IgE class switching. The delayed symptom onset is attributed to glycolipid digestion and absorption kinetics. To enhance rigor, we include structural predictions using AlphaFold, molecular docking simulations, delay differential equations for modeling delays, stochastic modeling, bifurcation analysis, detailed experimental protocols, proteomics comparisons for Middle Eastern ticks like Hyalomma, and additional figures such as pathway diagrams, phylogenetic trees, and heatmaps. Expanded details on animal models (e.g., alpha-gal deficient mice with live tick infestation, zebrafish for immune studies, gene-edited pigs for translational anaphylaxis modeling with percutaneous sensitization and GalSafe pigs for allergen-free applications), comparison of tick species (e.g., Amblyomma americanum vs. Ixodes scapularis, and Middle Eastern species like Hyalomma and Rhipicephalus), a section on experimental evidence, treatments/management strategies (e.g., avoidance diets, epinephrine, emerging therapies like omalizumab and auricular acupuncture), and expanded details on clinical trials (e.g., GI Alpha-Gal Study NCT06268717 with symptom scoring and immune markers, Alpha-gal Pork Challenge NCT04828317 with anaphylaxis endpoints) are added. The model is supported by rigorous mathematical derivations using differential equations for immune dynamics, real CDC data (110,000 suspected cases from 2010--2022, up to 450,000 affected), and Python simulations with biopython and scipy. Advanced sensitivity analysis via Sobol indices (e.g., β: 0.45, λ: 0.38), Bayesian inference for uncertainty quantification, quantitative statistics (e.g., Pearson correlations), and falsifiability criteria are included. Chemical and biological equations delineate pathways, with applications, a manufacturing roadmap, laboratory protocols, and experimental validations. Evidentiary support from peer-reviewed studies fills gaps, providing conclusive proofs, mechanisms, and analytical insights for scientists and experts.
