Descripción
A study on amphibian fauna at the lowland dipterocarp forest of Lubuk Semilang Recreational Park, Langkawi, Kedah, Peninsular Malaysia was conducted between December 2018 and June 2019. We recorded 18 species of amphibians from 14 genera and 6 families. These include seven new records for Lubuk Semilang, which are Fejervarya limnocharis, Limnonectes hascheanus, Megophrys aceras, Kaloula pulchra, Microhyla butleri, Pulchrana laterimaculata, and Polypedates discantus. We also recorded a new anuran record for Langkawi Archipelago, Pulchrana laterimaculata, and two endemic species of Malaysia, Leptobrachium smithi and Limnonectes macrognathus. Results from this survey indicate the amphibian species of the Langkawi Archipelago has increased from 28 to 29 species.

Cobertura geográfica
Lubuk Semilang Recreational Park is located at the base of Gunung Raya Forest Reserve, Langkawi, Kedah, Peninsular Malaysia. This forest covers 4,930 hectares and was declared a permanent forest in 1941 (Kedah Forestry Department, 2014). Lubuk Semilang Recreational Park is located beside Kampung Buku Malaysia and is approximately eight kilometres from the nearest town, Kuah. The stream at Lubuk Semilang, Sungai Korok, originates from the highest mountain of Langkawi, Gunung Raya (881 m a.s.l.). It flows into Sungai Kok, then into a larger stream, Sungai Melaka, before draining into the Straits of Malacca. In the Lubuk Semilang area, Sungai Korok is approximately two km long and it has a two–tier waterfall that is very popular for recreational and outdoor activities

Datos del proyecto
At Lubuk Semilang, only a small area had been explored and studied by previous researchers. Many areas around Lubuk Semilang, such as small streams, wetlands, swamps, seasonal pools, ditches and upper parts of Sungai Korok, remain unexplored. The present research was thus carried out to document amphibian species that inhabit the lowland dipterocarp forest of Lubuk Semilang.

| Descripción del diseño | This research was conducted at the lowland dipterocarp forest of Lubuk Semilang Recreational Park, Langkawi Island (06º 21' 47.97'' N – 99º 47' 30.17'' E, elevation < 100 m a.s.l.), Kedah, Peninsular Malaysia, between December 2018 and June 2019. Twenty–five consecutive visits were made. Samplings of amphibian species were performed at eight different habitat types: the lower, middle and upper part of Sungai Korok, small streams beside Mardi and Kg. Buku, marsh wetland, slow–moving stream, and road trail. Tadpoles and egg clutches were collected between 10:00 and 13:00 h using a scoop net, and they were then placed in plastic containers. Amphibian individuals were captured between 20:00 and 23:00 h by means of a Visual Encounter Survey (VES), by hand or a scoop net, and with the help of headlights and flashlights. Two to three field members were involved in the surveys. Each live specimen was photographed in situ using a compact camera (Nikon COOLPIX L840) before being collected for identification. We recorded habitat characteristics, including the type of vegetation, river width, water current flow, and canopy–covering. Microhabitat characteristics, which include horizontal position, vertical position and substrates, were also determined (Heyer et al., 1994). Horizontal position refers to the shortest distance of the species from any water bodies (streams or ponds). Vertical position refers to subsurface on the exposed soil surface (on a rock or on the plant), while substrate refers to the surface area that the individual sits on at the time of capture (rock, vegetation, log, mineral soil or dead leaf) (Zainudin, 2009; Zainudin et al., 2017). We also recorded abiotic conditions such as humidity, temperature, and weather using AccuWeather application (android). |

|---|---|
| Control de Calidad | Anuran species, including tadpoles, were identified based on their morphological characteristics, following by Smith (1930), Berry (1975), Inger et al. (2017), Norhayati et al. (2009), and Norhayati (2017). Taxonomic nomenclature was based on Frost (2019). |
Descripción de la metodología paso a paso:
- Measurements taken for each individual were: weight (WT), tibia length (TL) (length of the outer surface of the flexed knee to the heel/tibiotarsal inflection), snout–vent length (SVL) (length from the tip of snout to posterior margin of the vent), and head width (HW) (the widest part of the head or angle of the jaws) (Watters et al., 2016). Measurements were made using electronic scales and a caliper. We recorded habitat characteristics, including the type of vegetation, river width, water current flow, and canopy–covering. Microhabitat characteristics, which include horizontal position, vertical position and substrates, were also determined (Heyer et al., 1994). Horizontal position refers to the shortest distance of the species from any water bodies (streams or ponds). Vertical position refers to subsurface on the exposed soil surface (on a rock or on the plant), while substrate refers to the surface area that the individual sits on at the time of capture (rock, vegetation, log, mineral soil or dead leaf) (Zainudin, 2009; Zainudin et al., 2017).
