title: Data from: A new tetraradial olivooid (Medusozoa) from the Lower Cambrian (Stage 2) Yanjiahe Formation, South China

description: Octapyrgites elongatus n. gen. n. sp., a relatively rare, tetraradial
 olivooid (Cnidaria, Medusozoa), is described from Bed 5 of the Yanjiahe
 Formation (Cambrian Stage 2) near Yichang, China. Though similar to
 Olivooides and Quadrapyrgites from the Fortunian Stage in consisting of a
 partially corrugated (long.) periderm with a quadrate (transv.) apical
 portion and V-shaped apertural lobes, O. elongatus is substantially larger
 than other olivooids. The elongate apical region of O. elongatus is
 similar to four-sided Anaconularia anomala, though with a flat tip that
 may have been an adaption for a sessile mode of life. As in other
 olivooids, embryonic development in O. elongatus may have been direct.
 Lastly, the paucity of olivooids and the absence of pentaradial cnidarians
 and carinachitids in Cambrian Stage 2 indicate a marked decline in the
 disparity of cnidarians near the Fortunian/Cambrian Age 2 boundary, when
 by contrast bilaterians underwent rapid diversification.

title: Volatiles of bacteria associated with parasitoid habitats elicit distinct olfactory responses in an aphid parasitoid and its hyperparasitoid

description: 1.   To locate mating partners and essential
 resources such as food, oviposition sites and shelter, insects rely to a
 large extent on chemical cues. While most research has focused on cues
 derived from plants and insects, there is mounting evidence that indicates
 that microorganisms emit volatile compounds that may play an important
 role in insect behaviour. 2.    In this study,
 we assessed how volatile compounds emitted by phylogenetically diverse
 bacteria affected the olfactory response of the primary parasitoid
 Aphidius colemani and one of its secondary parasitoids, Dendrocerus
 aphidum. Olfactory responses were evaluated for volatile blends emitted by
 bacteria isolated from diverse sources from the parasitoid’s habitat,
 including aphids, aphid mummies and honeydew, and from the parasitoids
 themselves. 3.    Results revealed that A.
 colemani showed wide variation in response to bacterial volatiles, ranging
 from significant attraction over no response to significant repellence.
 Our results further showed that the olfactory response of A. colemani to
 bacterial volatile emissions was different from that of D. aphidum. Gas
 chromatography-mass spectrometry (GC-MS) analysis of the volatile blends
 revealed that bacterial strains repellent to A. colemani produced
 significantly higher amounts of esters, organic acids, aromatics and
 cycloalkanes than attractive strains. Strains repellent to D. aphidum
 produced significantly higher amounts of alcohols and ketones, whereas the
 strains attractive to D. aphidum produced higher amounts of the
 monoterpenes limonene, linalool and geraniol.
 4.    Overall, our results indicate that
 bacterial volatiles can have an important impact on insect olfactory
 responses, and should therefore be considered as an additional, so far
 often overlooked factor in studying multitrophic interactions between
 plants and insects.

title: Gene flow creates a mirage of cryptic species in a Southeast Asian spotted stream frog complex

description: Most new cryptic species are described using conventional tree- and
 distance-based species delimitation methods (SDMs), which rely on
 phylogenetic arrangements and measures of genetic divergence. However,
 although numerous factors such as population structure and gene flow are
 known to confound phylogenetic and species delimitation inferences, the
 influence of these processes on species estimation is not frequently
 evaluated. Using large amounts of exons, introns, and ultraconserved
 elements obtained using the FrogCap sequence-capture protocol, we compared
 conventional SDMs with more robust genomic analyses that assesses
 population structure and gene flow to characterize species boundaries in a
 Southeast Asian frog complex (Pulchrana picturata). Our results showed
 that gene flow and introgression can produce phylogenetic patterns and
 levels of divergence that resemble distinct species (up to 10% divergent
 in mitochondrial DNA). Hybrid populations were inferred as independent
 (singleton) clades that were highly divergent from adjacent populations
 (7–10%) and unusually similar (&lt;3%) to allopatric populations. Such
 anomalous patterns are not uncommon in Southeast Asian amphibians, which
 brings into question whether the high cryptic diversity observed in other
 amphibian groups reflect distinct cryptic species—or, instead, highly
 admixed and structured metapopulation lineages. Our results also provide
 an alternative explanation to the conundrum of divergent (sometimes
 non-sister) sympatric lineages―a pattern that has been celebrated as
 indicative of true cryptic speciation. Based on these findings, we
 recommend that species delimitation of continuously distributed “cryptic”
 groups should not rely solely on conventional SDMs but should necessarily
 examine population structure and gene flow to avoid taxonomic inflation.

title: Investigation of lightning ignition characteristics based on an impulse current generator.

description: Lightning strike is an important ignition source of forest fires.
 Artificial lightning discharge is a method for studying lightning fires.
 However, there is not enough data on the ignition of combustible materials
 caused by artificial lightning discharge. Previous studies on
 lightning ignition have focused on the heating and ignition effects of
 long continuing current (LCC), but the function of the impulse current
 that occurs before the LCC has not been taken into
 account. In this paper, an impulse current generator of 8/20 μs
 was used to simulate the ignition effect of impulse current on
 conifer needle beds. Different current waveforms have
 different ignition characteristics. We compared five kinds
 of conifer needle beds. The average of
 the current needed to ignite the needle bed of Larix
 gmelinii (Ruprecht) Kuzeneva was the smallest, and the average of
 the breakdown voltage was the smallest for the needle bed
 of Pinus massoniana Lamb. The total energy input to the
 conifer needle beds was fitted as a multiple log-linear
 regression model. The heating energy proportion value varies with
 different bulk densities, current amplitudes, and moisture contents. Based
 on this data, the heating energy of the impulse current transferred to the
 needles can be predicted. This information in conjunction with
 previous research on LCC was used to derive a lightning ignition
 prediction model of the full waveform for
 conifer needle beds.

title: Demographic characteristics, site and phylogenetic distribution of dogs with appendicular osteosarcoma: 744 dogs (2000-2015)

description: Objective: To report demographic characteristics of a contemporary
 population of dogs with appendicular osteosarcoma and assess the
 relationship between demographic characteristics, site distribution, and
 phylogenetic breed clusters. Design: Retrospective case series. Methods: A
 search of the Veterinary Medical Database was performed for dogs with
 appendicular osteosarcoma as a new diagnosis. Entries were reviewed for
 the sex, neuter status, age at diagnosis, breed, affected limb, and tumor
 location. The reported breed for purebred dogs was used to categorize each
 dog into one of five phylogenetic groups based on microsatellite analysis.
 Results: 744 client-owned dogs were included in the study. Study dogs were
 represented by a male-to-female ratio of 0.95:1.0, the majority of which
 (80.9%) were neutered. Most dogs were diagnosed between 7-10 years of age.
 The majority (77.8%) of dogs were large or giant-breed dogs. Purebred dogs
 comprised 80.4% of the population. The most common purebred breed affected
 by OS was the Rottweiler (17.1%). The most common phylogenetic group
 represented was Mastiff-Terrier (M-T, 26.3%). OS was more commonly located
 in the forelimb (64.2%) versus the hindlimb (35.8%), and the humerus was
 the most common site (20.9%). The distribution of age groups and tumor
 locations were significantly different between phylogenetic clusters. The
 distribution of age groups and neuter status were significantly different
 between size groups. Conclusions and Significance: The demographic data of
 canine appendicular OS are similar to previous reports. The data on
 phylogenetic associations can guide future studies aimed at evaluating the
 genomic mutations that contribute to OS development and its biological
 behavior.

 species: blue petrel Halobaena caerulea ("BP") and Antarctic
 prion Pachyptila desolata ("AP"). We also provoked them with a
 playback and measured acoustic parameters on their provoked calls.
 Fieldwork was performed in a small sub-Antarctic island (Ile Verte,
 49°51′S, 70°05′E) of the Kerguelen Archipelago, in the southern Indian
 Ocean, where blue petrels and the during the 2017 and 2018 birds’
 incubation period (25 November 2017 to 12 December 2017 and 27 November
 2018 to 20 December 2018 for blue petrels; 23 December 2017 to 16 January
 2018 and 25 December 2018 to 13 January 2019 for Antarctic prions).

title: Ecological traps and species distribution models: a challenge for prioritizing areas of conservation importance

description: Species distribution models analyse how species use different types of
 habitats. Their spatial predictions are often used to prioritize areas for
 conservation. Individuals may, however, prefer settling in habitat types
 of low quality compared to other available habitats. This ecological trap
 phenomenon is usually studied in a small number of habitat patches and
 consequences at the landscape level are largely unknown. It is therefore
 often unclear whether the spatial pattern of habitat use is aligned with
 the behavioural decisions made by the individuals during habitat selection
 or reflects actual variation in the quality of different habitat types. As
 species distribution models analyse the pattern of occurrence in different
 habitats, there is a conservation interest in examining what their
 predictions mean in terms of habitat quality when ecological traps are
 operating. Previous work in Belgium showed that Red-backed shrikes (Lanius
 collurio) are more attracted to newly available clear-cut habitat in
 plantation forests than to the traditionally used farmland habitat. We
 developed models with shrike distribution data and compared their
 predictions with spatial variation in shrike reproductive performance used
 as a proxy for habitat quality. Models accurately predicted shrike
 distribution and identified the preferred clear-cut patches as the most
 frequently used habitat, but reproductive performance was lower in
 clear-cut areas than in farmland. With human-induced rapid environmental
 changes, organisms may indeed be attracted to low-quality habitats and
 occupy them at high densities. Consequently, the predictions of
 statistical models based on occurrence records may not align with
 variation in significant population parameters for the maintenance of the
 species. When species expand their range to novel habitats, such models
 are useful to document the spatial distribution of the organisms, but data
 on population growth rates are worth collecting before using model
 predictions to guide the spatial prioritization of conservation actions.

title: Evolutionary dynamics of structural variation at a key locus for color pattern diversification in cichlid fishes

description: Color patterns in African cichlid fishes vary spectacularly. Although
 phylogenetic analysis showed already 30 years ago that many color patterns
 evolved repeatedly in these adaptive radiations, only recently have we
 begun to understand the genomic basis of color variation. Horizontal
 stripe patterns evolved and were lost several times independently across
 the adaptive radiations of Lake Victoria, Malawi, and Tanganyika and
 regulatory evolution of agouti-related peptide 2 (agrp2/asip2b) has been
 linked to this phenotypically labile trait. Here, we asked whether the
 agrp2 locus exhibits particular characteristics that facilitate divergence
 in color patterns. Based on comparative genomic analyses, we discovered
 several recent duplications, insertions, and deletions. Interestingly, one
 of these events resulted in a tandem duplication of the last exon of
 agrp2. The duplication likely precedes the East African radiations that
 started 8–12 Ma, is not fixed within any of the radiations, and
 is found to vary even within some species. Moreover, we also observed
 variation in copy number (two to five copies) and secondary loss of the
 duplication, illustrating a surprising dynamic at this locus that possibly
 promoted functional divergence of agrp2. Our work suggests that such
 instances of exon duplications are a neglected mechanism potentially
 involved in the repeated evolution and diversification that deserves more
 attention.

title: Winter is coming: harsh environments limit independent reproduction of cooperative-breeding queens in a socially polymorphic ant

description: Animals that live in cooperative breeding groups frequently inhabit harsh
 environments. It is widely accepted that harsh environments hinder
 independent reproduction, and this constraint favours individuals staying
 in family groups. Yet the assumption that harsh ecological conditions
 reduce the success of members of cooperative breeding groups when breeding
 independently has not been experimentally tested. We addressed this
 shortcoming using the socially polymorphic Alpine silver ant, Formica
 selysi. This species has single-queen (independent breeders), and
 multiple-queen (cooperative breeders) colonies coexisting within
 populations. We placed newly mated queens emerging from each type of
 colony to breed alone in either a harsh or mild winter condition and
 recorded their brood production and survival. Queens emerging from
 single-queen colonies were unaffected by the winter condition and had
 higher survival and larger broods than queens from multiple-queen
 colonies. In contrast, queens from multiple-queen colonies had higher
 mortality after a harsh than after a mild winter. These results support
 the long-held assumption that harsh environments constrain independent
 reproduction of members of cooperative breeding groups.

title: Data from: Vocal behavior of the Undulated Tinamou (Crypturellus undulatus) over an annual cycle in the Brazilian Pantanal: new ecological information

description: Tinamous (Tinamidae) are a group of Neotropical birds for which little
 information is available. The Undulated Tinamou (Crypturellus undulatus)
 is one of the most widespread species but also declining. Due to its
 secretive habits, ecological knowledge regarding the species relies on few
 anecdotal descriptions. We used automated recorders to monitor the vocal
 activity of the species over an annual cycle at four sites in the
 Brazilian Pantanal. We provide a description and analyze the diel and
 seasonal patterns of the calling activity in this species and provide new
 ecological information. The daily cycle showed two significant peaks in
 calling activity during the early morning and late afternoon, in agreement
 with the vocal behavior common among tinamous. The species was vocally
 active throughout the year, but it was significantly higher during
 September–October and March. This suggests that the breeding period of the
 Undulated Tinamou in the Brazilian Pantanal extends from September to
 April. After the months with highest calling activity, there was a strong
 decrease in activity, which might be related to the silent behavior of
 male tinamous during incubation. The seasonal pattern and breeding period
 identified for the Undulated Tinamou in the Brazilian Pantanal are in
 agreement with those observed in previous studies carried out with other
 Crypturellus species. The use of automated recorders, was found to be a
 useful method for monitoring the calling activity of this secretive group
 of birds, and might be useful in the assessment of future population
 trends in this and other declining tinamous.

title: Neutrino Mass as Geometric Lag in Force-Line Orbitals: A Geometric Rectification of Relativistic Delay and the True Nature of Neutrino Oscillations - RJW

description: I decided to take another look at the Neutrino:This preprint proposes a radical geometric reinterpretation of neutrino physics: neutrinos are not particles with intrinsic rest mass generated by the Higgs mechanism, but self-sustaining closed helical orbitals of force-lines propagating at the local speed of light. Effective mass emerges purely from relativistic delay due to extra geometric path length in the helix, creating drag against the c-limit without any new fields or fine-tuning.The derived bulk velocity v = c √(1 - r²/λ²), where r is the orbital radius and λ = hc/E the de Broglie wavelength, precisely reproduces observed relativistic neutrino velocities v/c ≈ 1 - (mν c² / 2E)² from time-of-flight experiments (MINOS, OPERA).Neutrino flavor oscillations arise from periodic "breathing" (radius modulation) in a braided three-force-line structure, not quantum mixing via the PMNS matrix. Three characteristic radii correspond to e, μ, τ flavors, with ∆m² derived geometrically from differences in 1/r² terms. Head-to-tail matter-antimatter pairing prevents annihilation via 180° phase opposition, while odd-number braiding (three lines) anchors the structure to 4D spacetime, naturally enforcing baryon asymmetry by mirroring and pumping antimatter to a 5D overlay—no CP violation or Sakharov conditions required.This maximally elegant model unifies photons (open helices, r → 0) and neutrinos (closed helices, finite r) on the same force-line substrate, explains three generations as discrete radius levels, resolves the hierarchy problem, smallness of masses, oscillation patterns, and matter dominance with one constraint (c-limit) and no additional physics.Indirect validation comes from existing data: MINOS/OPERA velocity lags, Super-Kamiokande atmospheric ∆m² implying r ~ 10⁻¹⁸ m, reactor antineutrino reversals consistent with phase inversion. Falsifiable predictions include E-dependent time-of-flight scaling in DUNE/Hyper-Kamiokande, coherence lengths in ESS/muon beams, and better χ² fits to L/E plots using geometric phase over PMNS.Builds on prior works: "Photon Reborn" and "Force Lines" (Zenodo records). Testable with current/near-future experiments; reanalysis of archival data can confirm or refute the geometric lag hypothesis.bAuthors Note:  It was the waves that are travling at C, they still take time to travel and dsince they cannot go faster than C, Neutrino's can't reach C and as such they do not bounce off of light speed.  This  realization on why they remain force lines of energy and do not knot up into vibrational energy knots explains the mechanism just like the photon and a few others.  They also hide the mass by the direction of the wave.  So lets catch a wave, or maybe not.  Hey its my paper, i get to make a pun or three.  God bless you and may you find elegance in a universe where it is every corner of the universe - RJW
