ABSTRACT
We examined the spatiotemporal variation of herpetofauna roadkills on roadways in Langkawi Island. A total of 131 roadkills were
recorded. The species that exhibited greater mortality was Varanus nebulosus (n=72). There was a significant difference in herpetofauna mortality between
dry and wet seasons (t(11) =-2.330, p=0.04, <0.05).
The spatial pattern was described by using kernel density estimation. Four collision
hotspots were concentrated at the west side of the island, adjacent to
vegetation area and forest reserve. Species characteristics, road proximity to
the forested area, vegetation cover and traffic volume may influence the high
rate of roadkills found. Installation of warning signs, speed restrictions and
temporary road closings could reduce traffic accident and significantly reduce
mortalities. The study represents a significant improvement over previous
research on the island by implementing hotspot analysis. We would suggest
analysing habitat suitability and connectivity to increase the ability to predict the
location of roadkill hotspots.
Keywords: Hot spot; kernel density; road mortality; spatio-temporal;
tropical island
ABSTRAK
Kami
mengkaji variasi reruang dan temporal korban jalan raya haiwan herpetofauna di Pulau Langkawi. Sejumlah 131 korban
jalan raya dicatatkan sepanjang pemerhatian dijalankan. Spesies yang
menunjukkan kematian yang paling tinggi ialah Varanus nebulosus (n = 72). Terdapat perbezaan yang signifikan dalam kematian herpetofauna antara musim kering dan lembap (t (11) = -2.330, p = 0.04, <0.05). Corak reruang dikaji dengan menggunakan anggaran ketumpatan kernel.
Empat kawasan titik panas korban jalan raya tertumpu di sebelah barat pulau, berhampiran
dengan kawasan vegetasi dan hutan simpan. Ciri sejarah kehidupan haiwan, jarak jalan ke kawasan hutan, kawasan tumbuhan dan kepadatan lalu lintas mungkin
mempengaruhi kadar korban jalan raya yang tinggi yang dijumpai. Pemasangan tanda-tanda amaran, sekatan kelajuan dan
penutupan jalan sementara boleh
mengurangkan gangguan trafik dan mengurangkan kemalangan trafik melibatkan hidupan liar. Kajian ini menunjukkan peningkatan yang signifikan terhadap penyelidikan terdahulu di Pulau Langkawi dengan pelaksanaan analisis kawasan panas. Kami
mencadangkan analisis kesesuaian dan
kesambungan habitat dijalankan untuk meningkatkan keberkesanan untuk meramalkan lokasi titik panas korban
jalan raya.
Kata kunci: Ketumpatan kernel; korban jalan raya; pulau tropika; reruang dan temporal; titik panas
