Dung beetles use #poop for feeding and nesting, with their larvae already hatching in a nutrient-rich environment. Some species roll using their front legs, such as this Oxysternon festivum rolling dung from a howler monkey in the Maracá Island, Roraima. 3/11
Did you know that not all dung beetles roll the dung? Some #species, such as Coprophanaeus lancifer, are known as tunnelers because they dig tunnels to bury their lunch and protect their nests just below the dung pile. 4/11
Also, not every #DungBeetle eats dung. Many species eat carcasses, decaying mushrooms and/or fruits. There are even beetles that are specialists in preying on millipedes, such as the species Deltochilum cupreicolle viridescens in these photos. 5/11
Some dung beetles have a “sit and wait” behaviour, perching on leaves while waiting for the dung smell - such as this Canthon triangularis species in forests of the Jari region, Pará. 6/11
Currently, there are more than 7000 species of #dung beetles distributed on all continents around the world, except Antarctica. 7/11
In @RAS_network, we use dung beetles to assess the condition of Amazonian forests. Many people don’t know but dung beetles help forest health through contributing to #SeedDispersal, #PestControl and #NutrientCycling. 8/11
Healthy and disturbance-free forests have a great diversity of species, sizes and colours (photo 1). Forests modified by anthropic and #climate disturbances, on the other hand, have few species, which are generally very small in size (photo 2). 9/11
After a drought and forest fires, our research found drastic losses in the diversity of dung beetles and in the associated seed dispersal and nutrient cycling activities within Amazonian forests. 10/11
But all is not lost! A recent study led by @Cassioan shows that having many #DungBeetle species with similar ecological function can offset the loss of rare species within human-modified Amazonian forests. 11/11
2. Com um componente forte de trabalho de pesquisa in loco, busca fornecer divulgação cientĂfica e interação com atores locais e regionais, especialmente tomadores de decisĂŁo.
1. @RAS_network is an international research network, mainly between Brazil and the UK, operating for over 10 years in the Amazon. RAS develops ecological and interdisciplinary research, including economic and social approaches.
2. With a strong in loco work component, it seeks to provide scientific dissemination and interaction with local and regional actors, especially decision makers.
3. The network is coordinated by 7 researchers and includes partners and students from more than 30 associated institutions through various projects. The network grew organically and has a fluid composition.
1. As florestas tropicais são conhecidas por seus sons bonitos e relaxantes, mas podem essas paisagens sonoras serem usadas para medir as mudanças na condição da #floresta? Um fio
3 Felizmente, muitos animais anunciam sua presença emitindo sons. Usamos esses sons (biofonia), juntamente com o ruĂdo humano (antropofonia) e sons da paisagem(geofonia) para aprender mais sobre a ecologia da floresta - um campo de pesquisa relativamente novo chamado #ecoacustica
