The scent of its nectar is a powerful lure and, in Malaysia, bats will fly up to 31 miles (50 km) to drink the nectar. Detritivores (also known as detrivores, detritophages, detritus feeders, or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces ).

Although for a time, fear of the creatures and the inaccessibility of their chosen habitat protected the tigers from human poaching, recent sea level rise is now threatening their existence. Once the deadfall has been chewed into fine pieces, bacteria, protozoans and microbes get to work breaking those particles into even smaller pieces. Treating animal hides with tannin alters the hides protein structure so it becomes soft, pliable, and resistant to decomposition. But without alternative means to make a living, year after year the honey hunters return to the forest. Medicinal properties from mangroves include relieving pain, decreasing inflammation, treating diabetes, acting as an antitumor drug, ridding the body of parasites, as an antiseptic, and many, many more.

Moreover, mangroves rely on mud buildup from rivers to help them make the transition, but studies suggest that in at least some parts of the world, mud isnt building up fast enough compared to the rate of sea level rise. However, the recent El Nino Southern Oscillation (ENSO) in the Pacific Basin has shown that sea levels can also drop precipitiously and have severe impacts on mangrove forests. We propose that integrating view point from community and ecosystem ecology in mangrove by quantifying energy fluxes from solar energy to producers, consumers and decomposers which can.
