title: Data from: Geographic variation in Megalorchestia californiana allele frequencies may be caused by winter rather than summer temperatures

description: There are many allozyme polymorphisms with latitudinal clines, for which
 selection by climate is one obvious explanation. Both warm summer
 temperatures and cold winter temperatures could plausibly impose selection
 on enzyme polymorphisms, but because summer and winter temperatures are
 usually geographically correlated, there has been little attempt to use
 patterns of geographic variation to discriminate between these possible
 selective factors. The glucose-6-phosphate isomerase and
 mannose-6-phosphate isomerase allozyme polymorphisms in the amphipod
 crustacean Megalorchestia californiana have clines that are strongly
 associated with mean January air temperature but are only weakly
 associated with mean August air temperature. This suggests that winter
 temperatures are more likely than summer temperatures to be a selective
 factor on these polymorphisms.

title: Data from: A giant spurrey on a tiny island: on the phylogenetic position of Sanctambrosia manicata (Caryophyllaceae) and the generic circumscriptions of Spergula, Spergularia and Rhodalsine

description: The only member of the generally herbaceous family Caryophyllaceae that
 may grow to a small tree is Sanctambrosia manicata, endemic to remote San
 Ambrosio Island, off the coast of Chile. The monospecific Sanctambrosia
 has been suggested to be closely related to Spergula and Spergularia
 (spurreys) on the basis of morphology, despite its treelike habit and
 gynodioecy. A plastid DNA dataset (ndhF, rps16, trnL-F) is used to
 investigate the relationships of Sanctambrosia and other members of
 Sperguleae. Sanctambrosia manicata is shown to be nested in a clade of New
 World and Australian Spergularia and the new combination Spergularia
 manicata is proposed. The volcanic San Ambrosio has been estimated to be
 almost three million years old, and S. manicata presumably evolved its
 treelike habit and gynodioecy over a short period of time. Spergula and
 Spergularia are monophyletic and recognizable by their number of carpels,
 five in Spergula and three in Spergularia. Spergularia fallax, which
 resembles Spergula in leaf characters, is shown to be sister to all other
 species of Spergularia. Minuartia subg. Rhodalsine belongs in Sperguleae
 and is sister to Spergula and Spergularia together, which supports the
 recent resurrection of Rhodalsine at the generic level.

title: Data from: Floral function: effects of traits on pollinators, male and female pollination success, and female fitness across three species of milkweeds (Asclepias)

description: PREMISE OF THE STUDY: Central questions in plant reproductive ecology are
 whether the functions of floral traits in hermaphrodites create conflict
 between sexes that could slow evolution, and whether individual floral
 traits function in pollinator attraction, efficiency, or both. We studied
 how floral traits affect pollinator visitation and efficiency, and how
 they affect male and female function and female fitness within and across
 three Asclepias species that differ in floral morphology. METHODS: Using
 separate multiple regressions, we regressed pollen removal, deposition,
 and fruit number onto six floral traits. We also used path analyses
 integrating these variables with pollinator visitation data for two of the
 species to further explore floral function and its effects on fruit
 production. KEY RESULTS: Most traits affected male pollination success
 only, and these effects often differed between species. The exception was
 increased slit length, which increased pollinia insertion in two of the
 species. There were no interspecific differences in the effects of the
 traits on female pollination success. All traits except horn reach
 affected pollination efficiency in at least one species, and horn reach
 and two hood dimensions were the only traits to affect pollinator
 attraction, but in just one species. CONCLUSIONS: Traits tended to
 function in only one sex, and more traits affected function through
 pollinator efficiency than through attraction. There was no significant
 link between female pollination success and female fitness in any of the
 three species; this pattern is consistent with fruit production not being
 limited by pollen deposition.

title: Data from: Chinese obstetrics and gynecology journal club (COGJOC): A randomized controlled trial.

description: Objectives: To assess whether a journal club model could improve
 comprehension and written and spoken medical English in a population of
 Chinese medical professionals. Setting: and participants The study
 population consisted of 52 medical professionals who were residents or
 postgraduate master or PhD students in the Department of Obstetrics and
 Gynecology, Heilongjiang University of Chinese Medicine, China.
 Intervention: After a three-part baseline examination to assess medical
 English comprehension, participants were randomised to either (1) an
 intensive journal club treatment arm or (2) a self-study group. At the
 conclusion of the 8-week intervention participants (n=52) were re-tested
 with new questions. Outcome measures: The primary outcome was the change
 in score on a multiple choice examination. Secondary outcomes included
 change in scores on written and oral examinations which were modelled on
 the Test of English as a Foreign Language (TOEFL). Results: Both groups
 had improved scores on the multiple choice examination without a
 statistically significant difference between them (90% power). However,
 there was a statistically significant difference between the groups in
 mean improvement in scores for both written (95% CI 1.1 to 5.0; p=0.003)
 and spoken English (95% CI 0.06 to 3.7; p=0.04) favouring the journal club
 intervention. Conclusions: Interacting with colleagues and an
 English-speaking facilitator in a journal club improved both written and
 spoken medical English in Chinese medical professionals. Journal clubs may
 be suitable for use as a self-sustainable teaching model to improve
 fluency in medical English in foreign medical professionals.

title: Data from: Causes and characteristics of reverse bird migration: an analysis based on radar, radio tracking and ringing at Falsterbo, Sweden

description: That birds migrate in the reverse direction of the expected is a
 phenomenon of regular occurrence which has been observed at many sites.
 Here we use three different methods; tracking radar, radiotelemetry and
 ringing, to characterize the flights of these reverse migrants and
 investigate possible causes of reverse migration of nocturnally migrating
 passerines during autumn migration at Falsterbo peninsula, Sweden. Using
 these different methods we investigated both internal factors, such as age
 and fuel load, and external factors such as weather variables, competition
 and predation risk. Birds flying in the reverse direction were more likely
 to be lean and to be juveniles. Reverse migration was also more common
 with overcast skies and winds with north and east components. We did not
 find any effect of temperature, visibility, number of migrating
 sparrowhawks, or the total number of ringed birds at the site on the day
 of departure. We found that reverse migration is characterized by slower
 flight speeds (airspeed) at high altitudes and that it takes place later
 in the night than forward migration.

description: This dataset contains the digitized treatments in Plazi based on the original journal article Vijver, Bart Van De, Wetzel, Carlos E. (2025): A new Punctastriata species (Staurosiraceae, Bacillariophyceae) from a nineteenth century sample collected by Charles-Henri Delogne. Phytotaxa 726 (3): 176-184, DOI: 10.11646/phytotaxa.726.3.5, URL: https://doi.org/10.11646/phytotaxa.726.3.5AbstractThe diatom genus Punctastriata (Staurosiraceae) includes small-celled taxa often indistinguishable from Staurosirella under light microscopy, complicating their identification in ecological and monitoring studies. Examination of a historic sample from Frahan (Belgium, Delogne collection) revealed two distinct Punctastriata species. One, with heteropolar clavate valves and variable spine positioning on both virgae and vimines, is described as Punctastriata davidwilliamsii Van de Vijver & C.E.Wetzel sp. nov. The second corresponds to P. glubokoensis, for which an emended description is provided. Both species were abundant in the Frahan material, and additional observations confirm they are more widespread in Europe than previously recognized. Frequent misidentifications with Staurosirella or poorly defined Punctastriata taxa underline the need for scanning electron microscopy in resolving this genus. The recognition of P. davidwilliamsii refines species concepts within Punctastriata and improves our understanding of the diversity and biogeography of small-celled araphid diatoms in European freshwaters.

This new species resembles two other widespread species, A. carnea and A. fortunei. However, it can be easily distinguished from A. carnea by its twisted and asymmetric flowers and conspicuous tubers, and from A. fortunei by its trifoliolate leaves, and purplish red and larger flowers. Molecular evidence suggests its position related to A. fortunei. Conservation status of A. calcicola is evaluated as Data Deficient (DD). The key to the Apios species is also updated.

title: Circulated Echovirus 18 strains in Guangdong Province and worldwide: a novel perspective on genetic diversity and recombination patterns

description: Echovirus 18 (E18) has re-emerged as a global public health concern in recent years because of its association with severe neonatal systemic diseases that pose a risk of high mortality. The lack of effective intervention strategies for E18 infections is largely attributed to limited knowledge regarding molecular epidemiology and recombination patterns. In this study, we obtained seven full-length E18 sequences from infants in Guangdong Province and combined them with representative sequences from GenBank. Using this expanded dataset, we analyzed the molecular epidemiological features, genetic characteristics, and recombination patterns of E18. Global statistics reveal a distinct double-peak pattern in the frequency of E18 infections throughout the year in the Northern Hemisphere. All strains isolated from clinical specimens were classified as genotype C2, which has emerged as the predominant circulating strain in Guangdong Province and globally. Several potential recombination events with E30 were identified among these seven strains, particularly in the P2 and P3 non-structural regions. This study offers new insights into the global dissemination, genetic diversity, and phylodynamicsof E18, potentially providing valuable information for designing antiviral vaccines and the implementation of sustainable surveillance strategies to enhance virus prevention and control during public health crises.
