The distribution of woody genera in the montane cloud forest in the northern highlands of Chiapas was registered and compared with other 23 localities in Mexico and Central America. A total of 312 genera in 99 families were recorded. The most diverse families were Rubiaceae (19), Leguminosae (16), Ericaceae ( 15) and Compositae ( 14). Quercus, Clelhra, Cornus, Oreopanax, and Ceslrum were present in more than 95% of the si tes, while 32 genera ( 10%) alone were registe red once. Non-metric multidimentional scaling analysis showed the presence of six groups of localities according to their diversity values and geographical position. Sierra de Manantlán, El Triunfo, Cordillera of Talamanca, and Northern highlands of Chiapas were the most diverse localities. The greater proportion of the genera (41 %) have a meridional distribution (except pantropical), 15% holarctic, 4% american-african, 9% malayan-american, 3% austral-antarctic, 14% pantropical, 5% widely distribution and 9% of the genera are considered exclusive of Mexico and/or Central America.

Ixchelia kochii Cuevas (Violaceae, Rinoreeae), a new species from western Mexico, is described and illustrated; it constitutes the third species of a recently described genus endemic to Mexico and Central America. The species grows in ecotones between tropical subdeciduous forest and montane cloud forest. The species of the genus are compared, and their relationships discussed.

Sideroxylon cochranei (Sapotaceae) from Sierra de Manantlán and Cuale, in Jalisco, México is here described and illustrated. It is morphologically close to S. salicifolium, but it differs from the latter in being montane cloud forest trees versus sea-shore to lower montane tropical trees, also in having clustered leaves with longer petioles and sepals and larger fruits. A key to the species of Sideroxylon in western Mexico and a distribution map are provided. According to IUCN criteria, its conservation status was assessed as critically endangered (CR).

Five different species of Copepoda were extracted from a leaf litter sample collected on the top (at 2000 m a.s.l.) of a cloud forested mountain in El Cusuco National Park, Honduras. Three of them, one Cyclopidae and two Canthocamptidae are new to science, and are described herein. Olmeccyclops hondo sp. nov. is the second representative thus far known of this New World genus. Moraria catracha sp. nov. and Moraria cusuca sp. nov. are the first formally described members of the genus occurring in Central America. The concept of a “Moraria-group” is considered to be an artificial grouping and is limited here to the genera Moraria and Morariopsis only. The distributional range of this group is essentially Holarctic, with the mountainous regions inHonduras, and probably in westNicaragua, as the southernmost limits in theNew World.

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.
