Dung Beetle Technical Advisory Group Report
Dung Beetle Technical Advisory Group Report The impact of tunnelling and dung burial by new exotic dung beetles (Coloptera: Scarabaeinae) on surface run-off, survivorship of a cattle helminth, and pasture foliage biomass in New Zealand pastures. Forgie SA, Paynter Q, Zhao Z, Flowers C, & Fowler SV. Landcare Research SUMMARY Eleven species of exotic dung-burying beetles were recently approved for release onto New Zealand agricultural pastures. Despite the formal assessment of risks and benefits by the Environmental Risk Management Authority in 2010/11, several stakeholders raised concerns over whether some of the key benefits demonstrated in overseas studies were applicable to New Zealand’s pastoral environment. As a result two New Zealand-based field trials were carried out 1/ to determine the effect of dung beetle activity on surface run-off and the amount of sediments suspended in the run-off; 2/ to assess the recovery of parasitic helminths from pasture around dung from infected livestock; and 3/ measure pasture foliage biomass. The dung beetles, Geotrupes spiniger (trials 1 + 2), Onthophagus binodis (trial 2) and Digitonthophagus gazella (trial 2) were used in the field trials. Secure field cages were used to apply three treatments (dung+beetles, dung-only and controls, without dung or beetles) on three livestock farms with three different soil types: sandy loam, clay loam and compacted clay. Results from trial 1 showed significant reductions in surface run-off at two extreme artificial rainfall events, and in total suspended sediments at the lower level, but still extreme rainfall event. Trial 2 showed reduced levels of Cooperia sp. -

Dung Beetles As Secondary Seed Dispersers: Impact on Seed Predation and Germination
Journialof Tropical Ecology (1998) 14:199-215.With 2 figures Copyright? 1998 CambridgeUniversity Press Dung beetles as secondary seed dispersers: impact on seed predation and germination VIRGINIA E. SHEPHERD and COLIN A. CHAPMAN' Departmentof Zoology,223 BartramHall, Universityof Florida, Gainesville,Florida, 32611, USA. E-mail. [email protected] (Accepted5 October1997) ABSTRACT. Dispersal of seeds away fromthe parent plant may facilitateescape fromdensity-dependent seed mortality.However, many post-dispersalevents can have a profoundinfluence on the survival of dispersed seeds. By incorporating seeds in the dung that dung beetles process forconsumption and oviposition,dung beetles could enhance seed survivalif they remove seeds fromareas of high pre- dation risk and place them in locations that avoid subsequent predation and that are suitable forgermination. The role of dung beetles in seed survivalwas investig- ated over 15 mo in Kibale National Park, Uganda. Depths of seeds buried by beetles, levels of predation on buried and unburied seeds, and germinationsuccess of seeds buried to differentdepths were examined. Results suggest that by burying seeds dung beetles increase the probabilitythat seeds will escape predation and germinate. Of seeds placed in dungpiles,69% remained at the surface,while 25% were buried from 1-3 cm in depth. Larger seeds were buried more shallowlythan smaller seeds. Buried seeds were less likelyto be removedby predatorsthan seeds at the surface.Germination of seeds buried at 1- and 3-cm depths was significantly higherthan seeds buried at 10 cm. For the species tested, many seeds were buried by dung beetles between 1 and 3 cm and at this depth there was a high probability of escaping predatorsand germinating.This demonstratesthe potential ecological importanceof dung beetles in facilitatingseed survivaland provides data to con- sider the role of dung beetles in the evolutionof seed attributes. -

M.S., Department of BiologicAl Sciences, Wright StAte University, 2020. Composition of dung beetle communities in a tropicAl montAne forest alters the rate of dung removal more than species diversity alone. Dung beetles provide key ecologicAl functions by degrading and recycling dung. I used experimentAlly-Assembled communities to eXAmine the role of species richness, community biomAss, species diversity, species identity, and community composition in dung removal, using Ateuchus chrysopyge, Copris nubilosis, Onothophagus cyanellus, And Dichotomius satanas. I hypothesized: (1) that as species richness, biomAss, and diversity increAses within a community, dung removal increAses; and (2) species are not functionally equivalent, so community composition should influence dung removal rates. As species richness, biomAss, and diversity of experimentAlly-Assembled communities increAsed, the proportion of dung removed also increAsed. -

The Effect of Dung Beetle Size on Soil Nutrient Mobilization in an Afrotropical Forest
insects Communication The Effect of Dung Beetle Size on Soil Nutrient Mobilization in an Afrotropical Forest Roisin Stanbrook 1,* , Edwin Harris 2, Martin Jones 3 and Charles Philip Wheater 3 1 Biology Department, University of Central Florida, Orlando, FL 32816, USA 2 Department of Agriculture and Environment, Harper Adams University, Newport TF10 8NB, UK; [email protected] 3 Department of Natural Sciences, Manchester Metropolitan University, Manchester M1 5GD, UK; [email protected] (M.J.); [email protected] (C.P.W.) * Correspondence: [email protected] Simple Summary: Dung beetles are known to instigate and provide a number of services, which benefit humankind. In addition to feeding on mammal dung, dung beetles also use dung to form underground brood balls which are used for larval development. This process instigates several ecological functions, such as dung removal and nutrient cycling. Recent studies have highlighted the importance of dung removal in pastoral and natural habitats but the effect of dung beetle body size on the amount of nutrients transferred when dung is buried remains unclear. In this preliminary study, we investigate the role of African dung beetle body size in nutrient cycling. We analyzed the nutrient content of soil directly underneath dung pats using three treatments containing dung beetles of varying sizes and one control treatment without beetles over a 112-day period. Our data show that dung beetle body size has a significant effect on the quantity of macronutrients transferred over time and that dung beetle body size is an important factor in the type and amount of nutrients transferred. -

Early Successional Colonizers Both Facilitate and Inhibit the Late Successional Colonizers in Communities of Dung-Inhabiting Insects

Diptera, Coleoptera, dung-inhabiting insects, competition, heterotrophic succession, successional mechanisms Abstract. The infl uence of early arriving species on the establishment and activity of later ones (the priority effect) is a key issue in ecological succession. Priority effects have been extensively studied in communities subject to autotrophic succession (plants, sessile animals), but only sporadically studied in communities subject to heterotrophic succession (e.g. dung or carrion inhabiting communities). We studied the infl uence of early successional colonizers on late successional colonizers by manipulating the suc- cessional processes in cow dung pats via delaying, and thus lowering, colonization by early successional insects. The decreased activity of early successional insects did not affect the species richness of late successional insects, but it did lead to increased abundance of colonizers. Late successional coprophagous beetles were facilitated by early successional species while larvae of late successional coprophagous fl ies were inhibited, presumably, by the larvae of early successional fl ies. -
A Review of the Status of the Beetles of Great Britain
Natural England Commissioned Report NECR224 A review of the status of the beetles of Great Britain The stag beetles, dor beetles, dung beetles, chafers and their allies - Lucanidae, Geotrupidae, Trogidae and Scarabaeidae Species Status No.31 First published 31 October 2016 www.gov.uk/natural-england Foreword Natural England commission a range of reports from external contractors to provide evidence and advice to assist us in delivering our duties. The views in this report are those of the authors and do not necessarily represent those of Natural England. Background Decisions about the priority to be attached to the conservation of species should be based upon objective assessments of the degree of threat to species. The internationally-recognised approach to undertaking this is by assigning species to one of the IUCN threat categories using the IUCN guidelines. This report was commissioned to update the national threat status of beetles within the Lucanidae, Geotrupidae, Trogidae and Scarabaeidae. It covers all species in these groups, identifying those that are rare and/or under threat as well as non-threatened and non- native species. Reviews for other invertebrate groups will follow.
