Taxon delimitation and identification are important in many areas of biology, especially in taxonomy and conservation. Taxonomic treatment is required to establish and justify recommendations in conservation biology for the group being considered. Imperfect and controversial taxonomy can undermine conservation assessment. We studied 71 populations; 665 individuals corresponding to the morphology of the Rosa sericea complex (including six taxa, one of which has extremely narrow distributions) were collected from sympatric, parapatric, and allopatric populations distributed in China. This study aims to investigate whether the complex species are macromorphologically different species and evaluate the rare taxa of the complex for conservation priority. The morphological characters and principal component analysis (PCA) of the R. sericea complex showed that the complex species have overlapping characters but can distinguish morphologically. The species of R. sericea complex systematics status based on previous DNA sequencing is controversial. The ecological habitat’s current morphological characters only delimit the R. morrisonensis (in Taiwan). To evade mistakes in species conservation, we recommend that taxonomical knowledge be needed to ensure success in protecting target species. Thus, the complementarity of systemic and conservation assurance makes conservation actions more necessary for the complex’s rare taxa. The ecological niche modelling (ENM) results showed that habitats of these conspecific taxa would be shrunken. With the presence of snapshots in time, the geography of taxa might decrease rapidly in representative entirely of the Geographic space (G-space) and Environmental space (E-space) that such taxa are bright to inhabit. So far, the significant inferences meant for the niche occupy the most incredible comparative research, taking the impermanent nature of taxa distributions and undertaking that such species are at a state of stability. If the artificially identified species (rarely distributed) are based on morphological identification, they must be conserved.
In Indonesian national economics, maize is a second food source after rice. The production of maize in some aspect is affected by the presence of insect particularly Orthopteran Order. The information of advantage and disadvantage of insects is useful for farmers. This research aimed to determine the species of Orthopteran and it is role to maize plant in the Village Kesiman, Denpasar. This research was conducted from December 2015 to February 2016. Insect was collected using sweeping net accordingly in each plot of maize plants. The plot was square form with the size of 10 m x 25 m. The sample was collected from the maize plant in the Ve phase until physiological maturation phase. in each phase, from 07.00 am until 10.00 am Bali time. Sample was collected for 15 minutes per plot and repeated three times. The insects collected was identified, and the insect density was predicted following Krebs (1989). As many as 242 individual insect which belong to Orthopteran Order was collected. Those belong to 8 families and 25 species. The species were Atractomorpha sp., Orchelimum sp., Phlaeoba sp., Gastrimargus sp., Urnisiella sp., Metaleptea brevicornis, Xenocatantops sp., Scudderia sp., Calolampra sp., Eritettix sp., Platyzoteria sp., Conocephalus strictus, Morabine sp., Acrida sp., Tenodera sp., Stagmomantis sp., Blattela sp., Periplaneta sp., Tettigidea lateralis, Mantis sp., Gryllus sp., and Anaxipha exigua, Tettigidea sp. 2, Tettigidea sp. 1, and unidentified (species x). Families that act as omnivores are Family Blattidae and Grillidae, families that act as herbivores are Pyrgomorphidae, Acrididae, Tettigonidae, Eumastacidae, and Tetrigidae, while families that act as predators are Mantidae.

Turkey is one of the most important temperate countries on Earth in terms of plant diversity. There is a growing interest in understanding habitat suitability and future distributions of species in the scientific world. Because climate change has impacted ecosystems with major consequences, species are shifting and declining much faster than in the past. Some global climate models used for predicting climate in the future better represent and have higher reliability for some climate types. Ferulago glareosa, which lives in Turkey, is a rare endemic plant species. In this study, we investigated current and future distributions of the species determined to be habitat-specific to lead to future studies on conservation. The Maxent model was used to map the current and future potential distribution of the species for Turkey. HadGEM2-ES and MPI-ESM-LR global climate models based on predicted future suitability of F. glareosa for 2050 and 2070 were examined. Models were constructed based on 20 presence points of the species and 2 abiotic variables. The current species distribution modeling of Ferulago glareosa predicted by the model produced very high success rates with training and test AUC values of 0.970 and 0.968, respectively. The true skill statistics value of the model (0.8245) indicated excellent model performance. In the end, we have demonstrated how predictions obtained from a highly reliable global climate model for a region's climate could provide more dependable insights into the future distribution of narrow-spread endemic species.
Ferulago glareosa, which is considered to be a threatened species lives in two different habitat patches (Type 1 and Type 2) in Kemah, Erzincan (Turkey). In this study, in order to provide guidance to the possible conservation studies for species, we have examined both floral visitors and impact of visitors on fruit set. The visitor abundances of species and the impact of visitors on fruit set were determined by observing them for a period of 2 hours for 8 days spread in both 2016 and 2017. The fruit set of individuals in two habitat patches were measured by counting fruits of 587 rays in 60 individuals. The difference between fruit set of individuals in Type 1 and Type 2 patches was determined to be quite statistically significant (0.11 and 1.12 respectively). Omophlus caucasicus was observed to cause the biggest damage to the fruit set of species. Different abiotic conditions in the habitat patches and the flowering phenology of species were found to have an impact on the visibility of species to insect herbivores. As a conclusion, the damages given to species by insect herbivores were found to have a strong correlation with the spatial and temporal variations in species habitat.
