Diversity and distribution of avifauna was studied at the tropical montane cloud forests of Horton Plains National Park, situated in the highland plateau of the Nuwara Eliya district from September 2015 to May 2016. Three main habitats were identified; cloud forest habitat, cloud forest die-back habitat and grassland habitat. Nine, 300 m line transects were marked in each of the habitats. Avifauna was recorded on three consecutive days of each month while travelling along these transects. Seventy eight species of birds were recorded during the study period. This included 66 resident species (with 13 endemic species) and 12 migratory species. The maximum value of the Shannon Wiener Index H' of 2.56 was recorded from the cloud forest habitat. In the cloud forest die-back habitat the H' was 2.49 and in the grassland habitat the H' was 2.31.The Jaccard similarity index, between cloud forest and cloud forest die-back was 0.58, and these two habitats had more common species. Cloud forest is the major habitat to be protected, with other habitats, in HPNP. Hence management of the HPNP should plan more actions to improve long term monitoring plans to warrant the protection of threatened species.Keywords: bird diversity and distribution, endemic birds, Horton Plains, tropical montane cloud forest

Abstract This study details two unique methods to quantify cloud-immersion statistics for tropical montane cloud forests (TMCFs). The first technique uses a new algorithm for determining cloud-base height using Moderate Resolution Imaging Spectroradiometer (MODIS) cloud products, and the second method uses numerical atmospheric simulation along with geostationary satellite data. Cloud-immersion statistics are determined using MODIS data for March 2003 over the study region consisting of Costa Rica, southern Nicaragua, and northern Panama. Comparison with known locations of cloud forests in northern Costa Rica shows that the MODIS-derived cloud-immersion maps successfully identify known cloud-forest locations in the United Nations Environment Programme (UNEP) World Conservation Monitoring Centre (WCMC) database. Large connected regions of cloud immersion are observed in regions in which the trade wind flow is directly impinging upon the mountain slopes; in areas in which the flow is parallel to the slopes, a fractured spatial distribution of TMCFs is observed. Comparisons of the MODIS-derived cloud-immersion map with the model output show that the MODIS product successfully captures the important cloud-immersion patterns in the Monteverde region of Costa Rica. The areal extent of cloud immersion is at a maximum during morning hours and at a minimum during the afternoon, before increasing again in the evening. Cloud-immersion frequencies generally increase with increasing elevation and tend to be higher on the Caribbean Sea side of the mountains. This study shows that the MODIS data may be used successfully to map the biogeography of cloud forests and to quantify cloud immersion over cloud-forest locations.

Lowland Forest at the complex of Bulusaraung mountain  in the Bantimurung Bulusaraung National Park is one of important habitat of birds in South Sulawesi. This study aimed to identify bird’s diversity in the Lowland Forest of Bantimurung Bulusaraung National Park for ecotourism purposes. This research was carried out for 2 months between April and May 2018. The data were gathered by using line transect method. The data were analyzed by using Shannon-Weiner diversity index, Evenness index, Margalef species richness index, and Sorensen Similarity index. The result of the study showed that, there were 23 species of birds found in the three lines of observation tracks. There were 19 species  found in Balleanging, 12 species  in Kattokaddaro and 15 species  found in Tompobulu.The highest value of bird diversity index was found in Tompobulu (H '= 1,73) followed by Balleanging (H' = 1,54) and Kattokaddaro routes (H '= 1,43). Therefore, the diversity of bird species in the three observation pathways can be used as objects and attractions in the development of ecotourism based on bird watching in wildlife conservation efforts.

AbstractLindu Enclave area is an area that cannot be separated from the Lore Lindu National Park (TNLL) because it is situated in the TNLL area. Lore Lindu National Park is located in the Wallacea area with high level diversity especially for the bird diversity. The existence of TNLL has an important role as habitat for 80% of Sulawesi endemic birds. This study aimed to determine the diversity of birds in the Lindu Enclave. Data was collected using PIA (Point Index of Abundance) method with 14 observation points which were scattered in two villages: Tomado Village and Anca Village. The results of bird watching analysis showed that as many as 51 species of birds from 25 families were found in the Lindu Enclave. Out of 51 birds, there were 14 species categorized in the protected birds and 15 species were endemic birds. Out of 15 species endemic bird, 4 species were categorized in the protected bird species.

AbstractLeaf beetles were studied in the Kovada Lake National Park (KL) and Kızıldağ National Park (KD) in Isparta province (Turkey) during April–October in 2009 and 2010. A total of 131 leaf beetle species were collected. In total, 88 species were detected from KL and 95 species from KD. Adult activity periods of the collected leaf beetle species were determined and their frequency and dominancy values were provided. The results showed slight differences in terms of the seasonal activity of the species in the two national parks. According to Shannon-Wiener index, the highest leaf beetle diversity among the studied months was found in early June (H’: 4.23) and late May (H’: 4.17). Sørensen similarity index of the species according to different seasonal periods showed three distinct seasonal periods: a) early April, b) late April to early July, c) late July to late October. Almost all leaf beetles showed a seasonal distribution, with the highest dominance during spring and early summer. The main reason for these different seasonal activities is that leaf beetle species are related to the quality and availability of host-plants.

A yearly biodiversity monitoring of longhorned beetles (Cerambycidae) in a Honduran cloud forest revealed a new species of prionine. Derobrachus cusucoensis sp. nov. is a locally relatively common species described from Cusuco National Park in Honduras, becoming the ninth species of this genus recorded for the country. Similar both in morphology and a montane habitat to D. dohrni, there is a possibility that this new species represents a disconnected population from the latter that evolved separately. An adapted insert for an existing identification key to all Derobrachus species is included.

Climatic variations influence the adaptive capacity of trees within tropical montane cloud forests species. Phenology studies have dominated current studies on tree species. Leaf vein morphology has been related to specific climatic oscillations and varies within species along altitudinal gradients. We tested that certain Neotropical broad leaf Magnolia species might be more vulnerable to leaf vein adaptation to moisture than others, as they would be more resilient to the hydric deficit. We assessed that leaf vein trait variations (vein density, primary vein size, vein length, and leaf base angle) among four Magnolia species (Magnolia nuevoleonensis, M. alejandrae, M. rzedowskiana, and Magnolia vovidesii) through the Mexican Tropical montane cloud forest with different elevation gradient and specific climatic factors. The temperature, precipitation, and potential evaporation differed significantly among Magnolia species. We detected that M. rzedowskiana and M. vovidesii with longer leaves at higher altitude sites are adapted to higher humidity conditions, and that M. nuevoleonensis and M. alejandrae inhabiting lower altitude sites are better adjusted to the hydric deficit. Our results advance efforts to identify the Magnolia species most vulnerable to climate change effects, which must focus priorities for conservation of this ecosystem, particularly in the Mexican tropical montane cloud forests.

The tropical montane cloud forest is an important reservoir of the diversity of Mexican ascomycetes. We cite and describe 17 species that had not been recorded in this vegetation type. Fifteen of them are new records for Mexico. Some of these species are associated with angiosperms and some with other fungi. Ongoing efforts are required to carry out floristic, taxonomic, phylogenetic and ecological studies of this group of fungi in such a diverse ecosystem that is cataloged as threatened.
