Diospyros lotus is the one of the most frost-tolerant species in the Diospyros genera, used as a rootstock for colder regions. Natural populations of D. lotus have a fragmented character of distribution in the Northwestern Caucasus, one of the coldest regions of Diospyros cultivation. To predict the behavior of D. lotus populations in an extreme environment, it is necessary to investigate the intraspecific genetic diversity and phenotypic variability of populations in the colder regions. In this study, we analyzed five geographically distant populations of D. lotus according to 33 morphological leaf traits, and the most informative traits were established, namely, leaf length, leaf width, leaf index (leaf to length ratio) and the length of the fourth veins. Additionally, we evaluated the intraspecific genetic diversity of D. lotus using ISSR and SCoT markers and proposed a new parameter for the evaluation of genetic polymorphism among populations, in order to eliminate the effect of sample number. This new parameter is the relative genetic polymorphism, which is the ratio of polymorphism to the number of samples. Based on morphological and genetic data, the northernmost population from Shkhafit was phenotypically and genetically distant from the other populations. The correspondence between several morphological traits (leaf width, leaf length and first to fifth right vein angles) and several marker bands (SCoT5, SCoT7, SCoT30: 800–1500 bp; ISSR13, ISSR14, ISSR880: 500–1000 bp) were observed for the Shkhafit population. Unique SCoT and ISSR fragments can be used as markers for breeding purposes. The results provide a better understanding of adaptive mechanisms in D. lotus in extreme environments and will be important for the further expansion of the cultivation area for persimmon in colder regions.

Understanding the effects of weather parameters on the population dynamics of an endangered geophyte supports monitoring efficiency

Due to their complex life cycles geophytes are often neglected in conservation programs, despite they are important elements of early spring communities. Their life cycle is strongly affected by weather parameters, i.e. temperature, precipitation, and light, but the effects of these parameters are often contradictory and show high intra-annual variability even within species. Deeper knowledge about the abiotic factors affecting the population dynamics of geophytes is needed to support the designation of effective conservation plans. We aimed to explore the link between weather parameters and population dynamics of Colchicum bulbocodium , an endangered and strictly protected geophyte. We monitored three life cycle stages (flowering, growing, fruiting) of 1069 individuals in permanent plots for six consecutive years. Our results showed that life cycle of C. bulbocodium was strongly related to the actual weather parameters; the lagged effect of the previous year was weaker. Increasing temperature and lack of cold periods had negative effect on all life stages. We highlighted that population estimation based on the number of flowering individuals in a single year can underestimate population size by 40–83%. Monitoring in years following wet and cold springs and cold winters could increase the accuracy of population estimations of the flowering individuals.

Due to their complex life-cycles geophytes are often neglected or mistreated during monitoring and conservation activities, despite they are important elements of early-spring communities. Their life-cycle is often strongly affected by weather parameters, i.e. temperature, precipitation, and light, but the main and combined effects of these parameters are often contradictory and show high intra-annual variability even within species. Deeper knowledge about the biotic and abiotic factors affecting the population dynamics of geophytes is needed to support the designation of evidence-based effective conservation plans. In our study we aimed to explore the link between weather parameters and population dynamics of Colchicum bulbocodium Ker-Gawl., an endangered and strictly protected geophyte. We monitored three phenological phases (flowering, assimilation, fruiting) of in total 1,069 individuals in Hungary, in permanent plots for six consecutive years. The effects of temperature- and precipitation-related weather parameters, as well as plot characteristics on the response variables were studied with generalized linear mixed models. Our results showed that phenology of C. bulbocodium was more strongly related to the actual weather than to the lagged effect of weather parameters of the previous year. Increasing temperature and lack of cold periods had negative effect on all phenophases. We highlighted that population estimation based on the number of flowering individuals in a single year can underestimate population size by 40–83%. Monitoring in years following wet and cold springs and cold winters could increase the accuracy of population estimations of the flowering individuals, while surveys in cold springs can estimate reproduction success the most accurately.
