Published: Feb. 18, 2024

Climate change and land cover often interactively affect plant species distributions. This study addresses the vulnerability of lowland upland orchids to climate change. Endemic New Guinea were grouped into four classes (lowland epiphyte, terrestrial, terrestrial) based on their life form elevation range. Forty occurrence records endemic selected for each class, totaling 160 records. Ensemble modelling combining two machine learning algorithms was used generate predictive current future suitable areas orchid classes. Model performance evaluated using AUC TSS metrics.

The Balkan Peninsula is considered one of the most important centres orchid diversity in Europe. However, patterns species richness Central Balkans have not been sufficiently studied so far. aim this study was, therefore, to identify and factors that influence spatial variation Balkans. For analyses, area was divided into 10 × km grid cells. environmental variables determined for each cell used analyses were altitude, bioclimatic variables, geological substrates habitat types. A random forest (RF) analysis predictors strongly associated with richness. In addition total number taxa, orchids three belowground organ types analysed separately: (a) rhizomatous orchids, (b) palmately lobed fusiform tubers (“palmate tuberous orchids”) (c) spherical or ovoid (“ovoid orchids”). Balkans, 54 subspecies recorded, are Tara, Zvijezda, Jadovnik Zlatar Mountains Ovčar-Kablar Gorge. general, two groups cells largest i.e., hotspots, stood out: (1) a large altitudinal range (2) occupied by gorges ravines. gradients influencing specific ranges, while climatic less important. affecting (Abieti-Fagenion, Ostryo-Carpinion orientalis Pinion nigrae forests), highlighting role heterogeneity. maximum percentage Abieti-Fagenion Vaccinio-Picetea forests minimum value mean temperature driest quarter determining palmate whereas xero-thermophilous (Ostryo-Carpinion orientalis, Asplenietea trichomanis nigrae) has greatest on orchids.

Forest Orchids under Future Climate Scenarios: Habitat Suitability Modelling to Inform Conservation Strategies

Plants, Journal Year: 2024, Volume and Issue: 13(13), P. 1810 - 1810

Published: June 30, 2024

Orchidaceae is one of the largest and most diverse families flowering plants in world but also threatened. Climate change a global driver plant distribution may be cause their disappearance some regions. Forest orchids are associated with specific biotic abiotic environmental factors, that influence local presence/absence. Changes these conditions can lead to significant differences species distribution. We studied three forest belonging different genera (Cephalanthera, Epipactis Limodorum) for potential current future protected area (PA) Northern Apennines. A Habitat Suitability Model was constructed each based on presence-only data Maximum Entropy algorithm (MaxEnt) used modelling. Climatic, edaphic, topographic, anthropogenic land cover variables were as predictors processed model. The aim identify factors areas likely contain habitats suitable providing refuge ensuring survival under scenarios. This will allow PA authorities decide whether invest more resources conserving refuges threatened species.

Published: Dec. 23, 2022

Wetland ecosystems are important habitats for the growth and survival of numerous terrestrial orchids in Europe. This study reviews current knowledge on wetland vegetation Central Balkans. The orchid flora was analyzed from taxonomic, phytogeographical, ecological conservation aspects. most taxa include two Balkan endemics (Dactylorhiza cordigera subsp. bosniaca D. kalopissi macedonica) three subendemics Balkans Carpathians cordigera, maculata transsilvanica Gymnadenia frivaldii), as well a considerable number European, Eurasian boreal representatives. Several occurring wet meadows fens have southern limit their distribution this part Europe, suggesting that wetlands refuges them. In total, 33 were recorded plant communities five classes, 10 orders 17 alliances. Most grow following types: (class Molinio-Arrhenatheretea, order Molinietalia caeruleae, alliances Molinion Deschampsion cespitosae Calthion palustris); Scheuchzerio palustris-Caricetea fuscae, Caricetalia alliance Caricion fuscae); tall-herb along mountain streams springs Mulgedio-Aconitetea); marshes herb-land freshwater or brackish water bodies Phragmito-Magnocaricetea). highlights importance serpentine silicate types orchids. addition, detailed chorological studies need to be carried out establish successful plan conservation.

Dactylorhiza maculata agg. (Orchidaceae) in Central Europe: Intricate Patterns in Morphological Variability, Cytotype Diversity and Ecology Support the Single-Species Concept

Folia Geobotanica, Journal Year: 2023, Volume and Issue: 58(2), P. 151 - 188

Published: June 1, 2023

Abstract Effective protection of endangered species is often limited by taxonomic discrepancies across state borders. This also the case Dactylorhiza maculata agg. in Central Europe, where one to three and several infraspecific taxa are recognized various countries. Based on an extensive analysis morphological variation, ploidy levels, environmental traits habitats 64 populations Europe adjacent regions, we aimed propose a unified concept applicable throughout study area. Multivariate revealed continuous variation at individual level only minor differences between particular clusters populations. Four DNA-ploidy levels were detected using flow cytometry. Diploids (2 n = 40) tetraploids 80) most abundant usually formed single-cytotype whereas DNA-triploids DNA-hexaploids occurred sporadically as minority cytotypes. The inferred patterns not congruent with traditional treatment regarding diploid D. fuchsii tetraploid two taxa. Instead, all analysed current best treated subspecies within s. lat. due somewhat morphotypes. A total eight may be which newly described here subsp. arcana , nov. Some nomenclatural riddles have been resolved, threat status discussed.

Abstract. Labajo-Villantes Y, Cootes J, Luo Y-B, Nuneza OM. 2024. Orchid diversity across different forest types on Mt. Malindang, Philippines. Biodiversitas 25: 605-615. Malindang Range Natural Park is one of the most significant biodiversity and conservation areas considered a hotspot. There have been many studies but information orchid taxonomy distribution limited. This study aimed to conduct comprehensive inventory orchids using an exploratory method. Samplings were conducted in types: montane, mossy, dipterocarp, mixed almaciga. A total 114 species with 55 endemics recorded. Three these (Phalaenopsis x intermedia Lindl., Paphiopedilum hennisianum (M.W.Wood) Fowlie, haynaldianum (Rchb.f.) Stein) under Appendix I (can only be exported specific circumstances). At same time, 78 II (follow controlled trades) categories Convention International Trade Endangered Species Wild Fauna Flora. P. haynaldianum, listed as endangered globally, observed montane mossy forests, respectively. Among six sampling sites, was species-rich, endemics, followed by forest. Almaciga dipterocarp forests closely related 100% similarity. The results this are valuable Malindang's ecological profile for more effective protection plans.
