Biodiversity, ecosystem functions and policy across a tropical forest modification gradient

Abstract
Tropical forests support over two-thirds of the world's terrestrial biodiversity. However, between 35% and 50% of tropical forests have already been degraded, and the rate of deforestation continues to increase. Secondary forests, plantations and other human-modified habitats now dominate tropical landscapes, leading to concerns that human degradation of these landscapes will elevate greenhouse gas emissions and jeopardise ecosystem services at local, regional and global scales. The area of protected forests is unlikely to increase greatly in the future, so the persistence of tropical biodiversity and the important biogeochemical cycles and ecosystem services associated with it will depend to a large extent on the way we treat the wider tropical landscape. The Human Modified Tropical Forests programme seeks to 'significantly improve our understanding of the links between biodiversity and biogeochemical cycles in tropical forests' through 'integrated observations and modelling linked to gradients in forest modification'. To contribute towards this goal our consortium will use surveys along a modification gradient within the SAFE landscape in Sabah (Malaysian Borneo) to detect patterns, combined with manipulative field experiments to gain a mechanistic understanding of biodiversity-function linkages. We will assess links between above- and belowground components of tropical biodiversity and investigate the extent to which different elements of biodiversity (e.g. species of conservation concern) are associated with measures of ecosystem function (decomposition processes and biogeochemical cycles). We will then upscale from the experimental sites to the landscape-scale to generate spatial layers of ecosystem function, biodiversity, and greenhouse gas fluxes to inform policy scenario modeling. Our work will thus (1) characterise soil microbial function and measuring associated biogeochemical fluxes; (2) Experimentally test the links between aboveground biodiversity and soil function; (3) Build and add to existing datasets for bird and mammals, and explore correlations between ecosystem functioning and the distribution of species of conservation concern; and (4) Explore policy scenarios for optimising biodiversity and function protection.
Planned Impact
The project will generate high quality research that will improve our comprehension of the impact of anthropogenic land-use alterations on the natural world. It will contribute greatly to the pool of excellent studies being published by UK academics, supporting our reputation as world-leaders in the field of global environmental change. To this end, the project is highly relevant to the NERC mission and delivers in relation to both its strategic 'biodiversity' and 'climate system' themes.
Who might benefit from this research? We have identified 5 key stakeholder groups listed below.
1: Academic community: please refer to the 'Academic Beneficiaries' section for details.
2: Oil palm and forestry industry groups: including oil palm producers (e.g. Sime Darby, Benta Wawasan), government agencies (e.g. Malaysian Palm Oil Board, MOPB; Indonesian Palm Oil Association, GAPKI; Sabah Forestry Department; Sabah Parks Department), research organisations (e.g. Center for International Forestry Research, CIFOR; Royal Society's SEnSOR programme) and consultancies (e.g. WildAsia Malaysia, Daemeter Consulting Indonesia, People Nature Consulting Indonesia, REDD+ Task Force).
3: UK and EU policy-makers: such as the Department of Energy and Climate Change (DECC; UK government department for international climate policy), Department of Environment, Food and Rural Affairs (Defra; producer of the UK Statement on Sustainable Palm Oil), Department for International Development (DFID; funder of research into poverty alleviation through oil palm production), and the European Commission (who make EU-wide decisions pertaining to palm oil production and consumption via instruments such as the Renewable Fuels Directive).
4. Non-governmental organisations: comprising of those working in forest-agricultural landscapes (e.g. Hutan- Kinabatangan Orangutan Conservation Project, Greenpeace, WWF, Conservation International, Rainforest Foundation).
5: General public: who demonstrate a keen awareness of tropical forest ecology, threatened species, oil palm production and climate change issues.

1: Academic community: please see 'Academic Beneficiaries'
2 & 4. Oil palm and forestry industry groups/Non-governmental organisations: our project findings will provide recommendations on how to maximise profitability of oil palm plantations while maintaining, or even enhancing, ecosystem function and biodiversity. This state-of-the-art knowledge will benefit organisations interested in both sustainable oil palm production and forestry, particularly in the context of policies (REDD+) and certification schemes (e.g. Forest Stewardship Council, FSC; Roundtable on Sustainable Palm Oil, RSPO; Roundtable on Sustainable Biofuels). By engaging these organisations in knowledge exchange throughout the programme of research, we can ensure that our work will be of value in terms of 'real-world' implementation and impact.
3: UK and EU policy-makers: increasing sustainable oil palm agriculture and reducing forest degradation/loss are key policy objectives globally. Our results will provide an informative evidence-base to support policy decision-making in this area, which is currently highly controversial, contradictory and dynamic (e.g. the recently introduced 'Nutella Amendment' in France, that has seen taxes on palm oil products increase by 300% due to environmental concerns; the recent decision by the EU to advocate palm oil produced according to RSPO guidelines as 'sustainable').
5: General public: the project will be of interest to the general population worldwide, as indicated by the substantial media coverage on tropical biodiversity and the associated impacts of human activities. This is an important means by which we can engage/inform the public about the value of biodiversity (e.g. its intrinsic worth, economic significance, ecosystem service provision) and promote awareness of sustainable use and conservation.

Description | One field campaign has been completed in Borneo. The field logistics and protocols for trapping bats and taking wing punches for stable isotope analyses have been refined, as have trapping procedures for putative prey. Experimental labelling of cow dung with enriched stable isotopes (via maize watered with 15N-label) has been trialled. We will now be able to trace greenhouse gases recycled from dung material incorporated into soils via both carbon and nitrogen tracers. |

Title | Mammal occurrence identified from metabarcoding of two leech species from Sabah, Malaysia |
Description | This dataset contains the results from a metabarcoding study of terrestrial leech blood meals to detect differences in the diets of two leech species, Haemadipsa picta and Haemadipsa sumatrana. Mammal taxa were identified using metabarcoding of 16s rRNA and comparisons of operational taxonomic units (OTUs) to a curated reference database from NCBI (National Center for Biotechnology Information) GenBank. All leeches were collected from the Stability of Altered Forest Ecosystems project (SAFE; www.SAFEproject.net) as part of the NERC Human Modified tropical Forest Programme and the LOMBOK consortia (Land-use Options for Maintaining BiOdiversity & eKosystem functions). Leech samples were collected at different sites across a habitat gradient, to assess these invertebrates as molecular sampling tools for mammals. Individuals were pooled before amplicon sequencing with Illumina MiSeq 150-200bp x2. The resultant raw sequences were filtered and clustered at 97%, curated and then assigned to the reference database using BLAST and MEGAN programmes. |
