Apostasioideae, consists of only two genera, Apostasia and Neuwiedia, which are mainly distributed in Southeast Asia and northern Australia. The floral structure, taxonomy, biogeography, and genome variation of Apostasioideae have been intensively studied. However, detailed analyses of plastome composition and structure and comparisons with those of other orchid subfamilies have not yet been co...

Orangeries, palm houses and orchid houses, the peculiar cultural complexes usually consituting the variety of the palace setting, due to the assigned „brittle matter” to them, need the extraordinary and stable care. Deprived of the farmer they quickly undergo destruction. The condition of the orchid house of the palace-park compex of the Łańcut castle, was disastrous within the post-war period....

Bees provide indispensable pollination services to both agricultural crops and wild plant populations, and several species of bees have become important models for the study of learning and memory, plant-insect interactions, and social behavior. Orchid bees (Apidae: Euglossini) are especially important to the fields of pollination ecology, evolution, and species conservation. Here we report the...

The two largest Atlantic Forest remnants in the state of Espírito Santo, eastern Brazil, namely 'Reserva Biológica de Sooretama' (REBIO Sooretama) and 'Reserva Natural Vale' (RNV), were surveyed for their orchid-bee faunas. Seventeen scent baits were used to attract orchid-bee males. Three-thousand, two hundred and twenty-five males belonging to 24 species were actively collected with insect ne...

Orchidaceae constitutes one of the largest families of angiosperms. Owing to the significance of orchids in plant biology, market needs and current sustainable technology levels, basic research on the biology of orchids and their applications in the orchid industry is increasing. Although chloroplast (cp) genomes continue to be evolutionarily informative, there is very limited information avail...

Studies on the development dynamics and the physiological properties of heterotrophic bacteria growing on the surface of the yellow waterlily {Nuphar luteum L.) during the plants' development cycle were carried out. It was stated that the number of the epiphytic bacteria is different in the examined sections of the plant. The number is higher on bottom parts of petioles and rhizomes but lower o...

BACKGROUND AND AIMS The advantage of clonal integration (resource sharing between connected ramets of clonal plants) varies and a higher degree of integration is expected in more stressful and/or more heterogeneous habitats. Clonal facultative epiphytes occur in both forest canopies (epiphytic habitats) and forest understories (terrestrial habitats). Because environmental conditions, especially...

A study on the occurrence and chitinolytic activity of planktonic, benthic and epiphytic bacteria was carried out in the Moty Bay of Lake Jeziorak near Ilawa. The greatest number of chitinolytic bacteria occurred on macrophytes. In terms of percentages, the chitinolytic bacteria share among heterotrophic bacteria was much greater in epiphytic and planktonic bacteria than in benthic ones. When c...

This paper describes a digital project in which ink-and-wash painting, an East Asian art form with a 1,300-year history, is drawn in interaction with an audience. This project was intended to analyze the traditional thoughts and techniques associated with the ink-andwash painting of an orchid, a design that expresses Eastern philosophy. The project relies on an interactive technique to demonstr...

The family Orchidaceae is not only one of the most diverse families of flowering plants, but also one of the most endangered plant taxa. Therefore, understanding how its species richness varies along geographical and environmental gradients is essential for conservation efforts. However, such knowledge is rarely available, especially on a large scale. We used a database extracted from herbarium...
