Photosynthesis was limited by low-intensity photosynthetically active radiation (PAR) and leaf wetness in a lower montane cloud forest (LMCF) of Cauca, Colombia. Mean PAR intensity remained below the saturation level for leaf-scale net photosynthesis (Pn) throughout the solar day during the wet season and for most of the solar day during the dry season. PAR represented a smaller fraction of total solar radiation (K↓) in LMCF than in lowland rain forest (LRF). In LMCF trees and shrubs, mean PAR-saturated Pn ranged from 4.3–10.6 μmol C m−2 s−1 at 1450 m, and from 3.5–10.2 μmol C m−2 s−1 at 2150 m. Pn was reduced by abaxial wetness in leaves of some trees and shrubs, and eliminated in others. This study indicates that persistent cloudiness and interception of cloud water by leaves limit LMCF productivity.

Tropical Montane Cloud Forest (TMCF) is one of Earth’s most neglected ecosystems around the globe. More than half of these forests are situated within Southeast Asia. Malaysia is known for its numerous mountains that are exceptionally rich in biodiversity and locally endemic species, but they are also threatened by expanding human activity such as forestry, agriculture, infrastructure, and climate change. The study aims to critically assess the current state of moist TMCF, focusing on their physical and biological potentials as Bio indicators through Bio monitoring at Fraser Hill and Cameron Highland, Pahang, Malaysia. The mix-methods of observation surveys are to identify physical attributes such as light intensity, altitudes, temperature, wind velocity and air humidity. Secondly, laboratory tests are to identify heavy metal contamination absorbed by mosses. Based on the findings collected around the trails, a connection between altitude and microclimate could be found. The study finds that as the altitude increases and the temperature decreases, the vegetation becomes more dwarfed. Secondly, results from the analysis at Abu Suradi trail within Fraser Hill and Brinchang Trail within Cameron Highland have a higher average of aluminium and iron concentration. Mosses were manifested as good key indicators of air pollution with heavy metals to Malaysia highland forest ecosystems. It showed differential accumulation of heavy metals located near sources of pollution. Thus, the moss data confirms the persistence of risk of pollution of highland forest ecosystems in Malaysia, which demands environmental management. Furthermore, decision makers, planners and designers around the region can evaluate and improve their local strategies related to Tropical Montane Cloud Forest (TMCF) conservation and preservation, especially highlands such as Fraser Hill and Cameron Highland.

Abstract A description is provided for Hypotrachyna sinuosa, which is most often observed on living bark of shrubs and trees in moist, nutrient-poor, often montane ecosystems, being typically a species of temperate often oceanic or montane rainforest, or of tropical montane cloud forest. Some information on its associated organisms and substrata, habitat, dispersal and transmission, and conservation status is given, along with details of its geographical distribution (Africa (Botswana, Ethiopia, Kenya, South Africa, Tanzania, Uganda), North America (Canada (British Columbia), Mexico, USA (Alaska, California, Florida, North Carolina, Oregon, Tennessee, Washington)), Central America (Costa Rica, El Salvador, Guatemala), South America (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Falkland Islands, Venezuela), Asia (Bhutan, China (Hubei, Sichuan, Yunnan), India (Sikkim, West Bengal), Indonesia, Japan, Malaysia, Nepal, Papua New Guinea, Philippines, Russia (Altai Republic, Irkutsk Oblast, Krasnoyarsk Krai, Primorsky Krai, Republic of Buryatia, Republic of Khakassia, Yakutia), Taiwan), Atlantic Ocean (Portugal (Azores, Madeira), Spain (Canary Islands)), Australasia (Auckland Island, Australia (Tasmania, Victoria), Campbell Island, Macquarie Island, New Zealand), Caribbean (Cuba, Dominican Republic, Guadeloupe, Haiti, Jamaica), Europe (Austria, Belgium, Bosnia and Herzegovina, Czech Republic, France, Germany, Ireland, Italy, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Switzerland, Ukraine, UK), Indian Ocean (Réunion), Pacific Ocean (New Caledonia, USA (Hawaii))). With its production of physciosporin, this species is one of several found to contain secondary metabolites able to inhibit motility of lung cancer cells in humans. Other uses of this species have all been as ecological indicators.
