: Indonesia has become one of the centres of genetic diversity of durian, but studies about superior local durian are still limited, so a study of morphological analysis is required to obtain potentially superior durians. This research aims: 1) To understand the morphological diversity of some local Criwik durians; 2) To obtain information about local durian that has potential characters as a superior local durian of Criwik Region. This research used descriptive explorative research method with sampling taken by purposive random sampling. The morphological character observations were made on both vegetative and reproductive organs and then analyzed using NTSYS 2.02. Based on this research, vegetative analysis revealed 10 accessions of durian that have morphological differences. In reproductive organ analysis we found local durians with distinctive superior properties.

: Romania’s natural resources are currently subjected to aggressive and barely controlled exploitation. These resources include medicinal plants from the spontaneous flora, which are much more in demand and appreciated on the foreign market than those derived from cultivation. Having information available regarding commercial societies (S.C.) and physical persons (P.P.) whose sphere of activity also comprises this resource, we wish to argue, taking Mureş county and the year 2017 as an example, the need for moderation in using all renewable as well as non-renewable resources. The requested quantities involved 109 spp. of spontaneous medicinal plants and amounted to 7,706 t (of which only 8 t required by P.P.), while the institutions authorized to perform adequate evaluation (AE) studies proposed 4,529 t and the NMC approved only 3,926 t . Certainly, S.C.s in particular are dissatisfied with the approved quantities and have recourse to a wide range of “strategies”. Even if in Mureş county pressure is not as high as in other counties in Transylvania, we believe that all organizations concerned with environmental conservation and protection should fight for the sustainable use ( uti sed non abuti ) of this important resource, which in most cases is subjected to other pressures in addition to those related to harvesting and export as raw material.

: This paper presents, on the basis of floristic and phytocoenotic data from field studies and the literature, the real vegetation map of Molhașul Mare from Izbuc peat bog, in the Apuseni Muntains. This oligotrophic bog, situated at 46°35’29” N and 22°45’43” E, is the most representative from this area and the least impacted by human activities, being therefore declared a Botanical Reserve. On its surface of c.8 ha, there have been identified, described on floristic and ecological grounds and mapped at 1:1000 scale, 9 plant community types that correspond to 4 Natura 2000 habitat types: 7110*, 7149, 7150 and 91D0*. The vegetation map will be useful for monitoring the conservation status of the plant communities and habitats and will facilitate the establishment of suitable conservation measures for the protection of the peat bog.

: Climate change is one of the biggest challenges of our century. As many climate models exist for the Romanian territory, each simulating a number of possible future scenarios for the emission of greenhouse gases, it is difficult to summarize the predicted impacts. This paper analyzes the output of a part of the Worldclim dataset, namely the 19 bioclim variables for 11 General Circulation Models, 4 RCP (Representative Concentration Pathway) scenarios and 2 years (2050, 2070) at 5 arc minutes (~10 km). These 19 variables were conceived to be relevant for species physiology across phyla, and are extensively used in current literature for species distribution modelling. In order to make informed choices in the fitting of models (simulations of future niche changes), an interpretation is needed for the future variation of each bioclim variable and each combination of GCM, year and greenhouse gas emission scenario (RCP). While GCM rankings are different for each variable and each year-RCP combination, some general characteristics can be derived for each GCM. For the Romanian territory, the hd model (HadGEM2-AO) can be considered overall as a pessimistic model in relation to temperature and precipitation variables (high temperature increase, high precipitation decrease). The mg GCM (MRI-CGCM3) can be regarded as an optimistic model in relation to predicted temperature increase (less warming), but also in relation to precipitation (higher rainfall). The mi (MIROC-ESM-CHEM) also usually predicts a more humid future in Romania, but with higher temperature increase. The ip GCM (IPSL-CM5A-LR) predicts the highest increase in temperatures during cold months in Romania, as well as drier winters and less temperature variability (monthly and yearly). A moderate model for our country is cc (CCSM4), which can be used as a balanced model (it is optimistic only for cold season temperatures, predicting the lowest increase). Overall, for temperature variables there is a general consensus (increase of temperatures for all combinations of GCM, RCP and year). Regarding precipitations the trends are not very clear. An exception is probably the RCP85 scenario, which causes most GCMs to predict a decrease in precipitation variables, but even for this scenario there are models indicating an increase. Abstract: Schimbările climatice reprezintă una dintre cele mai mare provocări ale secolului. Deoarece pentru teritoriul României există mai multe modele climatice, fiecare simulând un număr
