Climate-change-induced phenological changes in migratory birds are predicted from ecological theory and have been well-documented in temperate-zone breeding areas. By contrast, changes in arrival date on tropical wintering grounds have not been reported. To address this gap, we analysed birdwatchers' records of first arrival dates of 9 species of long-distance migratory birds in Singapore from 1987 to 2009. The study species included 1 raptor, 3 waders and 5 passerines. We compared the relative influence of year, Southern Oscillation Index and observer effort on arrival date. There was strong evidence for an arrival delay of approximately 2 d yr-1 (95% confidence intervals of 1-3 d) in Japanese sparrowhawk Accipiter gularis and curlew sandpiper Calidris ferruginea, but there was no change in arrival date for the other 7 species. We hypothesise that climate change is causing a shift in migration timing for some birds in Southeast Asia. A mechanism for the delay in these long-distance migrants may be that warmer temperatures enable species to remain on northern breeding grounds longer. Delayed arrival on the wintering grounds may have cascading effects on a migratory species' annual cycle, for example by influencing the arrival date at the breeding grounds, which can impact fitness. These potential impacts underscore the need for further work on the effects of climate change on migratory species in the tropics. © Inter-Research 2013.

We sampled and compared butterfly diversity on six land-bridge islands and two comparable control sites in forest on the mainland in Lake Kenyir, northern peninsular Malaysia, from Jun.2007 to Jan.2008 using 123 line transects. We recorded a total of 131 species in five families, three-quarters of which were Nymphalidae and Lycaenidae; nine additional species were observed moving between sampling sites. Butterfly assemblages on the smallest islands included species that tended to be smaller in size, less forestdependant, and were generally more wide-ranging compared to assemblages on large islands and control sites. We supplemented transect sampling with specimens from fruit-baited traps, which caught butterflies on mainland but not island sites. Notably, although control sites and large islands were more species-rich, species assemblages differed greatly among sites, suggesting that butterfly communities were not only weakly nested, but also spatially variable within a small landscape. Effective conservation of intact forest butterfly communities needs to take into consideration high between-site β-diversity arising from habitat heterogeneity even at small spatial scales. © National University of Singapore.

Outreach and education on conservation issues are crucial elements of successful conservation programmes. Big screen animations have a global reach, yet are not fully capitalised by conservationists. There remains great potential in developing them into powerful biodiversity and conservation education outreach tools despite known limitations in scientific value. We reviewed recent major animated films with multiple conservation themes (e.g. extinction, wildlife trade, ex-situ conservation) that feature tropical biodiversity, especially endemics, charismatic flagship or threatened species in authentic natural settings. We acknowledge that while the potential to develop animated films into effective biodiversity and conservation education tools is undoubted, there is a crucial need to complement them with supporting education materials, campaigns and activities. Partnerships formed between animation studios, conservation NGOs and local stakeholders will be essential in such efforts. © Ding Li Yong, Shun Deng Fam and Shawn Lum.

The first International Peat Congress (IPC) held in the tropics - in Kuching (Malaysia) - brought together over 1000 international peatland scientists and industrial partners from across the world (International Peat Congress with over 1000 participants!, 2016). The congress covered all aspects of peatland ecosystems and their management, with a strong focus on the environmental, societal and economic challenges associated with contemporary large-scale agricultural conversion of tropical peat.
