Over 10 years ago, Oryx published initial details of an investigation into the effects of selective timber logging on primates in the Sungai Tekam Forestry Concession in peninsular Malaysia (Johns, 1983). This original 2-year field study developed into a long-term monitoring programme, in which the recovery of primates in the regenerating forest is to be recorded throughout the logging cycle. This is the only such monitoring programme so far established in the world's tropical forests. The dataset is now complete for forests logged up to 18 years ago.

AbstractWe present the results from an ongoing long-term monitoring of the 22 GHz H2O maser in W49N with the 100-m Effelsberg radio telescope from February 2014 to September 2017. The unique Effelsbergs spectral line observation capability provides a broad velocity range coverage from −500 to +500 km s−1 with a spectral resolution better than 0.1 km/s. Following the strong major outburst in W49N in late 2013, we have started a long-term monitoring programme at Effelsberg. The major outburst feature (up to 80,000 Jy at VLSR − 98 km s−1) faded away by June 2014. However, we found that the site is still active with several high velocity outbursts (both blue and redshifted). Some features appear at extremely high velocities (up to ±280 km s−1) and show rapid flux variations within a 1-2 month period. This sub-year scale variability implies that the water masers could be excited by episodic shock propagation caused by a high-velocity protostellar jet.
