“…Environmental factors predicted whether this species was present using the Jackknife test. From the current and future models, the species' habitats are classified into four categories, namely, not suitable (≤0.10), low suitability (0.11-0.30), moderate suitability (0.31-0.70), and high suitability (≥0.71) [18].…”

Crepidium ridleyi (J.J.Sm.) Szlach. is one of the endemic terrestrial orchids from Java. Due to rapid development and habitat fragmentation, it faces a severe threat of extinction. In this study, we predict the specific habitat of C. ridleyi within Java Island using the future greenhouse gas emission scenarios of RCP 4.5 and RCP 8.5 for the years 2050 and 2070. The occurrences were found in protected sites but have yet to be conserved in ex-situ sites. The current and future of this species distribution model comparison showed that habitat suitability is declining, even projecting the extinction in the worst scenario in the far future. Thus, supporting active conservation efforts for this species is strongly advised to protect it from extinction and use it sustainably.

“…As this region suffers huge loss of forest area, some habitats of Rafflesiaceae have also been destructed. Sumatra, home of 11 species of Rafflesia, has been rapid and potentially represents a serious risk to native species [5]. Consequently, a member of Rafflesiaceae has been being threatened with extinction [5,6].…”

Insect visits and variation of floral temperatures during blossoming of Rafflesia gradutensis

2023

The survival of parasitic plant Rafflesia depends on the host plant, habitat condition, vegetational types, , pollination and the dispersal of seeds. This study aims to investigate visits by insects and variation in floral temperatures of Rafflesia gradutensis during flowering. The flower was observed to be visited by green fly Lucilia sericata and weaver ant Oecophylla sp. The number of visits L. sericata was 617 times and 337 times by Oecophylla sp, in which most of the visits occur during mid-day. The average observed highest surface temperatures of were 28.40C (perigone) and 28.70C (diaphragm), which were slightly above the air temperature of 27.80C. The temperature experiences a gradual increase from the morning till the noon, and then it decreased toward late afternoon. The results of the floral temperatures indicate endothermy in R. gradutensis. However, thermo-regulation related to endothermy needs further investigation.

“… Kukushkin et al (2017) accounted for the limited distribution of hemiparasitic Arceuthobium oxycedri in the low mountain areas of Crimea by GIS techniques, which may be related to the formation of its host Juniperus deltoides range in the late Pleistocene-Holocene and a low speed of the hemiparasite dissemination from Quaternary refugia in the Crimean Peninsula. Renjana et al (2022) predicted the suitable potential habitat of the parasitic Rafflesia arnoldii by studying the potential distribution of its host plants through MaxEnt model. Indeed, several recent studies have considered the impact of future climate change on both parasites and host plants.…”

Predicting the potential distribution of four endangered holoparasites and their primary hosts in China under climate change

Climate change affects parasitic plants and their hosts on distributions. However, little is known about how parasites and their hosts shift in distribution, and niche overlap in response to global change remains unclear to date. Here, the potential distribution and habitat suitability of four endangered holoparasites and their primary hosts in northern China were predicted using MaxEnt based on occurrence records and bioclimatic variables. The results indicated that (1) Temperature annual range (Bio7) and Precipitation of driest quarter (Bio17) were identified as the common key climatic factors influencing distribution (percentage contribution > 10%) for Cynomorium songaricum vs. Nitraria sibirica (i.e., parasite vs. host); Temperature seasonality (Bio4) and Precipitation of driest month (Bio14) for Boschniakia rossica vs. Alnus mandshurica; Bio4 for Cistanche deserticola vs. Haloxylon ammodendron; Precipitation of warmest quarter (Bio18) for Cistanche mongolica vs. Tamarix ramosissima. Accordingly, different parasite-host pairs share to varying degree the common climatic factors. (2) Currently, these holoparasites had small suitable habitats (i.e., moderately and highly) (0.97–3.77%), with few highly suitable habitats (0.19–0.81%). Under future scenarios, their suitable habitats would change to some extent; their distribution shifts fell into two categories: growing type (Boschniakia rossica and Cistanche mongolica) and fluctuating type (Cynomorium songaricum and Cistanche deserticola). In contrast, the hosts’ current suitable habitats (1.42–13.43%) varied greatly, with highly restricted suitable habitats (0.18–1.00%). Under future scenarios, their suitable habitats presented different trends: growing type (Nitraria sibirica), declining type (Haloxylon ammodendron) and fluctuating type (the other hosts). (3) The niche overlaps between parasites and hosts differed significantly in the future, which can be grouped into two categories: growing type (Boschniakia rossica vs. Alnus mandshurica, Cistanche mongolica vs. Tamarix ramosissima), and fluctuating type (the others). Such niche overlap asynchronies may result in severe spatial limitations of parasites under future climate conditions. Our findings indicate that climate factors restricting parasites and hosts’ distributions, niche overlaps between them, together with parasitic species identity, may jointly influence the suitable habitats of parasitic plants. Therefore, it is necessary to take into account the threatened holoparasites themselves in conjunction with their suitable habitats and the parasite-host association when developing conservation planning in the future.
