Its peculiar morphology has made its phylogenetic placement a subject of ongoing debate. It was initially suggested to be placed in Sphaerasteridae, the same family as fossil species. However, subsequent detailed skeletal analyses of the fossil forms suggested that this similarity was likely due to convergent evolution. Recent molecular analyses have revealed that Valvatida, in which the genus is currently placed, is likely a large polyphyletic group, leaving its taxonomic position still unresolved. New information A detailed examination of the internal skeletal structure of <i>Podosphaeraster toyoshiomaruae</i>, collected from the seas around Japan, was conducted using micro-focus X-ray computed tomography. Concurrently, shotgun sequencing was performed to identify key molecular markers for recent asteroid phylogeny. Additionally, shotgun sequencing determined the complete mitochondrial genome. Despite conservative evolution amongst asteroidean mitochondrial genomes, a translocation of the <i>COX2</i> gene was revealed, representing the first discovery of a major protein-coding gene translocation within Asteroidea. In the phylogenetic tree, <i>P. toyoshiomaruae</i> was positioned as the most basal lineage within Valvatida. However, the statistical support for this placement was low, potentially due to the long-branch attraction caused by the excessively rapid evolutionary rate. Images reconstructed by micro-CT confirmed the presence of calcified reinforcement in the mesentery and showed its detailed structure for the first time. The mesentery skeleton was found to connect to the V-plate and five pairs of plates, including three kinds of marginal plates. This suggests that the marginal plates of this species may not be homologous with those of other asteroids. Although varying degrees of marginal plate reduction are shared with the order Velatida, we consider this to be a case of convergent evolution. Our phylogenetic analysis indicates a close relationship between <i>P. toyoshiomaruae</i> and Poraniidae (and other Valvatida), all of which possess marginal plates differentiated to varying extents, the homology of which remains uncertain.</p>","PeriodicalId":55994,"journal":{"name":"Biodiversity Data Journal","volume":"14 ","pages":"e194006"},"PeriodicalIF":1.3,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13551059/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148914543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reports the occurrence of triple clutching in three falcon species - Common Kestrel (<i>Falco tinnunculus</i>), Saker Falcon (<i>Falco cherrug</i>) and Peregrine Falcon (<i>Falco peregrinus</i>) - reared in captivity in Bulgaria. Two breeding pairs per species were monitored during the 2011-2020 breeding seasons under controlled conditions with optimal husbandry and nutritional regimes. Clutch frequency, egg production, fertility rates, hatching success and chick survival were recorded for each pair. Results revealed that both monitored pairs of each species produced three successive clutches within a single season, with varying degrees of reproductive success. These findings suggest that under good captive conditions, triple clutching is a feasible reproductive strategy in falcons and may significantly enhance the productivity of conservation breeding programmes. Further research is needed to determine the physiological limits and welfare implications of induced high‑frequency breeding in raptors Triple clutching within a single breeding season is rarely documented in falcons, particularly under captive conditions. This study reports the occurrence of triple clutching in three falcon species - the Common Kestrel, Saker Falcon and Peregrine Falcon - maintained in captivity and monitored over the 2011-2020 breeding seasons. Two breeding pairs per species were observed under controlled husbandry and nutritional conditions and clutch frequency, egg production, fertilisation, hatching success, chick survival and breeding outcome were recorded for each pair. All monitored pairs produced three successive clutches within a single breeding season, although the mechanism differed amongst species. Triple clutching occurred naturally in Common Kestrels under full parental care, whereas in Saker and Peregrine Falcons, it was induced through egg removal and artificial incubation. Reproductive output remained high across successive clutches, with viable eggs and healthy chicks produced in all three species, despite some reduction in egg size in later clutches of Saker and Peregrine Falcons. These findings demonstrate considerable reproductive plasticity in falcons and show that, under favourable captive conditions, triple clutching can substantially increase breeding output. The results highlight the practical value of multi-clutch breeding for captive propagation and conservation programmes involving re-introduction or population reinforcement.</p>","PeriodicalId":55994,"journal":{"name":"Biodiversity Data Journal","volume":"14 ","pages":"e197934"},"PeriodicalIF":1.3,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13531023/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148876502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 73 visitation events involving 17 insect species were recorded on <i>C. discolor</i>. Diptera accounted for most visitation events, but no dipteran or lepidopteran visitors carried pollinaria.

In <i>C. striata</i>, a single visitation event by <i>Eucera nipponensis</i> was recorded and the observed individual carried pollinaria on the head and transported them between flowers. This observation is consistent with previous reports from Japan and suggests a possible mechanism of pollinator sharing that should be tested through broader temporal and population-level observations. The results reveal a clear mismatch between visitation frequency and pollinaria transport in <i>C. discolor</i>, with pollinaria attachment restricted to a subset of bee visitors. Together with previous studies, our findings support a generalised food-deceptive pollination strategy in <i>C. discolor</i> mediated by locally available bees.

Focusing on mammal species in Nigeria, we used phylogenetic logistic regression to test the influence of five biological traits: body mass, brain mass, generation time, current geographic range and historical range contraction, on extinction risk across nine IUCN threat categories. Standardised models were used to compare trait sensitivity across threats. Brain mass emerged as the most consistent and influential predictor of extinction risk across threat categories, including agriculture, biological resource use, urban development and, notably, climate change, where it was the strongest predictor of all models. Species with larger brains, often primates and carnivores, were highly vulnerable. Geographic range size was a strong negative predictor of risk across most models, with range-restricted species more susceptible to habitat loss and fragmentation. Generation time was positively associated with risk under direct human pressures, but inversely linked under climate threats. Body mass showed weak and inconsistent effects overall, though it was significantly and negatively associated with extinction risk under agriculture and aquaculture. The number of species affected was highest under direct human pressures, compared to indirect anthropogenic threats, such as climate change and pollution. Extinction risk in Nigerian mammals is shaped by intrinsic traits that interact predictably with human pressures. Species with large brains, small ranges and slow reproduction are at greatest risk. Trait-based models can improve conservation planning by identifying vulnerable species before population declines become critical, especially in regions facing intensive land-use change.</p>","PeriodicalId":55994,"journal":{"name":"Biodiversity Data Journal","volume":"14 ","pages":"e191439"},"PeriodicalIF":1.3,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13525407/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148857365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
