State: Yunnan



Coordinate: 22° 10' N, 100° 38' E
Coordinate basis: stated in text

Geography comments: "in the Naban river valley... in Xishuangbanna"

Environment
Habitat: tropical/subtropical dry broadleaf forest

Protection: nature reserve

Substrate: ground surface

WMT: 25.0

CMT: 15.0

MAP: 1600.0

Habitat comments: there are "three distinct seasons: cool-dry (October-January, with the lowest monthly temperature of 15°C in December), hot-dry (February-April, with the highest monthly temperature of 25°C in April) and a rainy season (May-September) with most of the mean annual precipitation of almost 1,600 mm. . The natural vegetation of the study region is tropical rainforest, falling into different types of evergreen and seasonal forests... most cultivated land is covered by plantations of rubber"

Methods
Life forms: ground beetles

Sites: 4

Sampling methods: no design,malaise traps,pitfall traps,other traps

Sample size: 486 individuals

Years: 2008, 2009

Seasons: dry,wet or monsoon

Sampling comments: "Beetle sampling was carried out by using a combined trap system including pitfall traps and Malaise traps (Townes 1962) at all sites, and aerial collectors in the canopy area of trees in forests and in rubber plantations. Pitfall traps were plastic pots with a diameter of 8.5 cm and a depth of 13 cm buried flush to the soil surface, one-third filled with 10% formalin solution. At each site, five pitfall traps were arranged at a distance of ca. 3 m from each other around a Malaise trap. Aerial collectors were constructed of two pieces of transparent plastic plates (50 x 30 cm, height x width) which were arranged crosswise and fixed upon a red plastic bowl of 30 cm in diameter. These traps were installed on canopy tree branches using ropes... Traps were installed in different seasonal periods cov- ering (a) the beginning of the rainy season (May-July 2008), (b) the beginning of the cool-dry season (September-November 2008), and (c) the transition period from the hot-dry to the rainy season (March-June 2009)"
four "forest" sites were sampled
