El Niño impacts on human‐modified tropical forests: Consequences for dung beetle diversity and associated ecological processes

Abstract: Our knowledge of how tropical forest biodiversity and functioning respond to anthropogenic and climate‐associated stressors is limited. Research exploring El Niño impacts are scarce or based on single post‐disturbance assessments, and few studies assess forests previously affected by anthropogenic disturbance. Focusing on dung beetles and associated ecological functions, we assessed (a) the ecological effects of a strong El Niño, (b) if post‐El Niño beetle responses were influenced by previous forest disturban… Show more

“…We touch on several such directions here. Well‐designed comparative approaches comparing ecological patterns across ecological gradients and boundaries produce new and more general insights (see Chatelain, Elias, Guilbert, & Soulier‐Perkins, ; Mottl, Fayle, Yombai, Novotný, & Klimeš, ; Rabl, Gottsberger, Brehm, Hofhansl, & Fiedler, ; Raine, Slade, & Lewis, , all available in this issue). Expanding attention into a wider spread of invertebrate taxa adds insights as a wider range of ecosystem functions is encompassed (see Chatelain et al, , Drinkwater, Williamson, Clare, & Rossiter, , Luke, and Phillips, Chung, Edgecombe, & Ellwood, , all available in this issue). Using the rapid response times of invertebrates in terrestrial ecosystems allows us to evaluate impacts of and recovery from environmental transformations due to natural and human actions (see Franca et al , Luke et al, , Stone, Shoo, Stork, Sheldon, & Catterall, , Torppa, Wirta, & Hanski, , all available in this issue). The availability of effectively limitless computing power potentially allows the enormous complexity of tropical food webs and distribution maps (see Scriven et al, , this issue) to be modeled realistically: Interpreting very complex model systems of course may be as challenging as contemplating the real thing (McLane, Semeniuk, Mcdermid, & Marceau, ). Aligning pattern and process: Does tropical biodiversity matter beyond its intrinsic value? Can ecosystem processes and service survive a massive decline in invertebrate species and density?…”

“…We measured functional traits of dung beetles and parrotfish, along with two key ecosystem functions: secondary seed dispersal rates by dung beetles in forests and grazing rates by herbivorous parrotfishes on reefs. All datasets were sampled before and after the onset of the 2015-2016 El Niño (forest: 2010 and 2016; reef: 2014 and 2017; for further details see supplementary material and [44,74]). We, hence, compared post-El Niño functional diversity metrics and biodiversity-ecosystem function (BEF) relationships with those from pre-El Niño surveys.…”

“…These environmental barriers are likely to shift as climate change contributes to increasing temperatures with major impacts on species distributions. Climate change is also expected to increase the frequency of droughts and fires which have been shown to have a major effect on invertebrate communities such as dung beetles (França et al, , this issue). Dung beetles play a major role in ecosystem functioning, and their sensitivity to environmental extremes suggests that climate change will have a major effect on the dynamics of tropical habitats.…”
