“…Parmesan (2006) states that temperature increases due to climate change are expected to have an impact on plant diversity and distribution at all levels from single species to biomes. An increase in temperature also has the potential to change the quality and cause habitat instability that can cause species loss, changes in species diversity, abundance and distribution (Enquist 2002;Davis et al 2005;Malcolm et al 2006;Lovejoy 2008;Jump et al 2009;Kreyling et al 2010). Walther et al (2002) states that climate change can change population dynamics in native species, can increase climate-mediated biological invasion of other species, change interactions and community structures, and ecosystem functions.…”

Possibly Extinct or Data Deficient? A challenge for conservation status assessment based on single locality: Insights from Beilschmiedia lancifolia Miq.

The assessment of plant extinction is strongly influenced by the number of populations and the number of localities found for the species target. A larger population and a large number of localities, the results of the assessment will be easier to conclude. However, if the population and location of the plant are not known, even if there is only one location recorded in the herbarium, then there is a challenge in determining the final result of the assessment. This paper will reveal the challenges and the final results of the assessment where only one location is known based on the herbarium records. The species is Beilschmiedia lancifolia Miq. The species was first published in 1852 collected from Mount Ungaran, Indonesia. There have been no additional records of B. lancifolia since its first collection. To update the conservation status of the species, we conducted population assessment in Mount Ungaran using a focused survey method. In spite of the intensive surveys on each side of Mount Ungaran within the species' known elevation range, we could not find a single individual of B. lancifolia. Based on our findings, we proposed to add the Possibly Extinct (PE) to the present status of B. lancifolia.

“…Other research has already shown that there is a generalized change in the natural calendars (phenology) of plants and animals, as well as changes in the distribution of some species (Lovejoy, 2008). Some tree species may be able to adapt to climate change, allowing trees to survive in many nature reserves, but some cannot (Jinghua et al, 2014).…”

The Tazekka National Park, created in 1950 on an initial area of 680 hectares, located in the mountain range of the Eastern, Middle Atlas, offers a great variety in terms of the landscape and the diversity of forest populations. However, studies have reported that the park’s biodiversity is threatened due to anthropogenic and climatic factors. The aim of this work is to carry out a comparative study concerning the influence of climate change during the years 1985, 2007 and 2018 on the distribution of plant species in different stations of the Tazekka National Park (Ras al ma, Bab Boudir, Bab Azhar and Jbel Tazekka).To carry out this work, several field trips were carried out. The results obtained in the form of GIS using the ArcGis 10.4.1 software have shown that climate change significantly influences the plant biodiversity of the Park. It is necessary to find assessment, monitoring and management strategies for these climate risks in order to preserve phytobiodiversity.

“…Species distribution models based on GCMs are also used in nature conservation planning and preventing invasive species expansion 16 – 19 . Considering possible negative impact of climate change modification of temperature and precipitation patterns together with extreme weather events can alter geographical ranges of species 20 , their ecological interactions 21 , and the timing of biological events (phenology), which could fundamentally transform ecosystems and food webs 22 .…”

Loss of fungal symbionts and changes in pollinator availability caused by climate change will affect the distribution and survival chances of myco-heterotrophic orchid species

The first comprehensive species distribution models for orchid, its fungal symbionts and pollinator are presented. To evaluate impact of global warming on these organisms three different projections and four various climate change scenarios were analysed. The niche modelling was based on presence-only records of Limodorum abortivum, two species of Russula and three insects pollinating orchid (Anthophora affinis, Bombus terrestris, Rhodanthidium septemdentatum). Two sets of orchid predictions were examined—the first one included only climatic data and the second one was based on climate data and data on future distribution of orchid fungal symbionts. Overall, a poleward range shift is predicted to occur as a result of climate change and apparently global warming will be favorable for L. abortivum and its potential geographical range will expand. However, due to the negative effect of global warming on fungal symbionts of L. abortivum, the actual extension of the suitable niches of the orchid will be much limited. Considering future possibility of cross-pollination, the availability of A. affinis for L. abortivum will decrease and this bee will be available in the worst case scenarios only for 21% of orchid populations. On the other hand, the overlap of orchid and the buff-tailed bumblebee will increase and as much as 86.5% of plant populations will be located within B. terrestris potential range. Also the availability of R. septemdentatum will be higher than currently observed in almost all analysed climate change projections. This study showed the importance of inclusion of ecological factors in species distribution models as the climate data itself are not enough to estimate the future distribution of plant species. Moreover, the availability of pollen vectors which is crucial for long-term survival of orchid populations should be analysed in context of climate changes.
