We provide distribution maps of carnivorous plants as well as an assessment of rarity status and potential threats to diversity of carnivorous taxa in Saskatchewan using a biodiversity informatics approach. Saskatchewan is home to ten carnivorous species ranging from the Mixed Grassland ecoregion in the southwest to the Selwyn Lake Upland ecoregion in the northeast. Several areas exhibiting high carnivorous plant diversity including rare and endangered species are: the Nesbitt Provincial Forest, the Prince Albert National Park, and the Athabasca Sand Dunes. We propose these areas as deserving conservation priority.

Abstract The aims of this study were to demonstrate the role of forests in the Roztoczański National Park as a refuge for rare and endangered saproxylic Coleoptera as well as recognition of entomological fauna related to dead wood. The study was conducted in the strictly protected are of Bukowa Góra from 20th April to 30th September 2012 and focused on the wood of beech and fir. We inventoried saproxylic beetles by means of nine ‘Netocia’ traps, which resulted in a total of 135 recorded species, of which 52 had not been reported in the park before. Twenty-one rare and endangered species were found. The high number of new species in the Roztoczański National Park indicates a high biodiversity value of the area. Our studies therefore show that the strictly protected area of Bukowa Góra is a biodiversity hot spot of saproxylic Coleoptera.

Information on the18 species of vertebrates included in the Red Book of the Russian Federation and the Red Book of the Chelyabinsk Region habitats in the territory of the Zyuratkul National Park is presented. The developed system of functional zones in the Zyuratkul National Park is presented in order to ensure the safety of animals living on its territory. The analysis of literary sources describing the Red Book species of vertebrates inhabiting this territory is presented, on the basis of which the necessary requirements for their habitat are characterized and the climatic conditions formed in the studied territory are described. The general geographical features of the area are revealed, the laws of natural and economic territorial complexes are established. The established boundaries of the habitats of vertebrates are highlighted and plotted on schematic maps. Proposals have been developed to adjust the boundaries of previously defined functional areas. Proposals have been made for monitoring the number of rare and endangered species of vertebrates and monitoring anthropogenic load.

Carnivorous Species

The approximately 800 species of carnivorous plant together provide a classic example of convergent evolution. The known carnivorous species and genera represent nine independent angiosperm lineages. They are united by a suite of five essential traits that together make up the ‘carnivorous syndrome:’ (1) capturing or trapping prey in specialized. usually attractive, traps; (2) killing the captured prey; (3) digesting the prey; (4) absorption of metabolites (nutrients) from the killed and digested prey; and (5) use of these metabolites for plant growth and development. Although many other ‘paracarnivorous’ plants have one or two of these traits, only plants that have all five of them that function in a coordinated way can be considered true carnivorous plants.

Carnivorous Species

Stylidium species (triggerplants) are claimed to be protocarnivorous based on the presence of glandular hairs, observations of trapped small organisms, and induction of proteinase activity. However, these traits might serve alternative functions. We aimed to re-assess and quantify the degree of carnivory for Stylidium species in an ecological context, by comparing the natural abundance (δ15N) of Stylidium species with co-occurring carnivorous (Drosera species) and non-carnivorous plants in their natural habitats. We hypothesised that the δ15N signature of Stylidium species would more closely match co-occurring carnivorous plant species than their non-carnivorous counterparts if they rely on captured organisms as a nutrient source, since there is an increase in fractionation by 3–5 ‰ per trophic level. Our results show that the Stylidium species sampled had δ15N signatures that matched more closely with co-occurring non-carnivorous plants than with carnivorous Drosera species. This does not support the claim that they rely on captured organisms as a nitrogen source, or the source is negligible. Other studies have shown that protocarnivorous species have a δ15N signature that is more similar to that of co-occurring carnivorous than that of non-carnivorous species. Therefore, our findings question the protocarnivory status of Stylidium species.

The value of the Salair Ridge territory for the creation of the “Togul” National Natural Park is determined primarily by the natural complex of black coniferous forests with the participation of relict plant species of the Miocene-Pliocene coniferous-deciduous forests and a group of early flowering ephemeroid plants, old-aged Pinus sibirica, Picea obovata and linden forests and a variety of tall grasses. Based on the performed geobotanical descriptions, the phytocenotic characteristic of linden forests was compiled. Information is provided on the location of 10 rare and endangered species of plants and fungi found during a survey of the territory of the planned national park.

This article considers Grey Owl’s tenure in Saskatchewan’s Prince Albert National Park as a “telling instance” of the ways in which iconic Canadian wilderness spaces have been constructed in white settler culture and law – not only through the erasure of Indigenous people(s), but also through highly visible forms of cultural appropriation, including the installation of “imaginary Indians.” Placed in the context of the complex history of Treaty Six, the story of Grey Owl reveals how white settler culture and law have been constructed with reference to two “imaginary Indians”: the “Bolshevik Indian” and the “Park Ranger Indian.” The former, figured as a source of lawlessness and destruction, is erased from the terrain of the nation; the latter, represented in this case by Grey Owl, figures the “consent” of “Indians” to settler law, “naturalizes” Canadian sovereignty, and bestows upon the nation a heritage of “Indian” culture that it is otherwise felt to be lacking.

Collections of greenhouse plants of the Peter the Great Botanical Garden of the BIN RAS are very diverse and include more than 12500 taxa. Over the long history of the collection, certain principles of acquisition were formed: geographical, systematic, phylogenetic, environmental and morphological. For greenhouse collections, the presence of rare and endangered species, medicinal, food and economically important plants is very important. In addition to the correct approach to the selection of plants, you must also carefully consider the competent demonstration of the taxa presented. Plants that visitors can see in the exposition greenhouses should have a habit more or less corresponding to how these species look in natural conditions. In the case of blooming, decorative leaf species or cultivars, try to find an exposure option in which their decorative qualities will be presented most fully. The object of our study was representatives of Commelinaceae family. Among these plants, in addition to the well-known to us Tradescantia L. and Callisia Loefl., there are a large number of species and cultivars that are highly decorative, and there are also representatives with medicinal and environment-improving properties. The analysis of exposure options for plants of this group is carried out. The most suitable ones were selected depending on the structural features of the shoot system, and the severity of the decorative qualities of these plants. Data are provided on the results of processing cuttings of Tradescantia zebrina Bosse. retardants. These drugs should prevent the stretching of the shoots, lead to a thickening of the stem, an increase in the size of the leaf plate, more active growth of the roots. This experiment was aimed at reducing the time spent on maintaining the decorativeness of a number of species and cultivars of Commelinaceae grown in pots.

These are days of small books and single volumes. Multi-volume sets are a rare and endangered species. The completion of Horton Davies's five-volume set on Worship and Theology In England is a major achievement in our age, and an uprecedented one in any age. Never before has the worship life of an entire people for four and one-third centuries received such a balanced and careful scrutiny. Over fifteen years of research have borne plentiful and rich fruit. This work of the Henry W. Putnam Professor of Religion at Princeton University marks an achievement in liturgical studies unequalled by living scholars in the English-speaking world.

Post Mortem Findings

Background The zoo is a unique environment in which to study animals. Zoos have a long history of research into aspects of animal biology, even if this was not the primary purpose for which they were established. The data collected from zoo animals can have a great biological relevance and it can tell us more about what these animals are like outside the captive environment. In order to ensure the health of all captive animals, it is important to perform a post-mortem examination on all the animals that die in captivity. Methods The causes of mortality of two hundred and eighty two mammals which died between 2004 and 2015 in three different Italian zoos (a Biopark, a Safari Park and a private conservation center) have been investigated. Results Post mortem findings have been evaluated reporting the cause of death, zoo type, year and animal category. The animals frequently died from infectious diseases, in particular the causes of death in ruminants were mostly related to gastro-intestinal pathologies. pulmonary diseases were also very common in each of the zoos in the study. Moreover, death was sometimes attributable to traumas, as a result of fighting between conspecifics or during mating. Cases of genetic diseases and malformations have also been registered. Discussion This research was a confirmation of how conservation, histology and pathology are all connected through individual animals. These areas of expertise are extremely important to ensure the survival of rare and endangered species and to learn more about their morphological and physiological conditions. They are also useful to control pathologies, parasites and illnesses that can have a great impact on the species in captivity. Finally, this study underlines the importance of a close collaboration between veterinarians, zoo biologists and pathologists. Necropsy findings can help conservationists to determine how to support wild animal populations.

In modern biology, a search for efficient and safe ways of long-term storage of animal genomes is vital for the survival of rare and endangered species. To date, the only reliable method of prolonging the preservation of genome is deep freezing of somatic and reproductive cells, including spermatozoa. Here we overview the current state of reproductive technologies and present the cryopresevation strategies of genetic material of selected amphibian species. These strategies were developed at the Institute of Cell Biophysics, Russian Academy of Sciences, Pushchino, Russia. Cryopreservation could help managing the threatened populations of amphibian species through genome storage and mediate the production of healthy animals from the stored material.
