Floristic Differentiation Between Mid-Seral Communities Of Abandonedcharcoal Kilns In The Forests Of The Gargano Promontory (South Italy), Franco Pedrotti, Dan Gafta
Turkish Journal of Botany
We searched for patterns in species composition and richness of mid-seral communities developed on abandoned charcoal hearths that might be induced by differences in succession progress and forest context. One phytosociological relevé was performed on each of the 22 charcoal platforms located in beech (Anemono apenninae-Fagetum) and oak-hornbeam forests (Doronico-Carpinetum). The ratio of forest understorey to non-forest species richness (F/nF) at plot level was used as a proxy for the succession progress. There was a sharp differentiation of plant communities due to their floristic resemblance with the understory vegetation of the forest type in which they were integrated. Nevertheless, these …

Yuhina Nigrimenta Blyth (Zosteropidae) As A Bird Pollinator Ofbrandisia Hancei Hook.F. (Scrophulariaceae) During Winter, Yifan Qian, Yun Xiang Li, Xuemei Zhang, Qiu Mei Quan
Turkish Journal of Botany
Winter-flowering plants commonly attract an insufficient number of pollinators. Harsh climate conditions, such as low temperature, make it impossible for insects to evolve as reliable pollinators. Birds can buffer against changes in weather to be more reliable pollinators for these kinds of plants, such as Brandisia hancei Hook.f. (Scrophulariaceae), a shrub endemic to the Northeast Sichuan Basin in China. In this study, the flower visitors, flowering phenology, pollinators, breeding system, and nectar availability of B. hancei Hook.f. were investigated. Results show that the flowering period duration was approximately 3 months for the whole population and more than 10 days per …

Relationships Between Sorghum Bicolor (Poaceae) And Its Closerelatives Based On Genomic In Situ Hybridization Evidence, Qing Liu, H L, Jun Wen
Turkish Journal of Botany
Sorghum bicolor (L.) Moench (sorghum) is a naturally well-established diploid species with 2n = 2x = 20. Here we provide evidence to identify the genomic relationships of S. bicolor and its extant relatives using genomic in situ hybridization. The genomic divergences between S. bicolor and its close relatives may be presented as: S. bicolor-S. x drummondii (Nees ex Steud.) Millsp. & Chase < S. bicolor-S. x almum Parodi < S. bicolor S. arundinaceum (Desv.) Stapf < S. bicolor-S. propinquum (Kunth) Hitchc. Sorghum arundinaceum probe signals showed spotted or painted patterns on the S. bicolor chromosomes, indicating that the degree of genomic divergence between S. bicolor and S. arundinaceum is distinct. It is reasonable to infer that S. bicolor might have diverged from S. arundinaceum in the early diversification history of the subgenus. The probe signal intensity of S. arundinaceum and S. propinquum is greater on the 17 chromosomes than on the remaining 23 chromosomes of S. halepense (L.) Pers., whereas S. bicolor and S. propinquum probes produced spotted or patchy signals on the 40 S. halepense chromosomes. Therefore, the degree of genomic divergence may be presented as: S. halepense-S. bicolor < S. halepense-S. arundinaceum < S. halepense-S. propinquum.
