Reptile bycatch in a pest-exclusion fence established for wildlife reintroductions
Conservation fences have been used as a tool to stop threatening processes from acting against endangered wildlife, yet little is known of the impacts of fences on non-target native species. In this study, we intensively monitored a pest-exclusion fence for 16 months to assess impacts on a reptile community in south-eastern Australia. We registered 1052 reptile records of six species along the ...


Austropotamobius pallipes reduction vs. Procambarus clarkii spreading: management implications
One of the main threats to native European crayfish is the spread of alien crayfish species that are immune carriers of the detrimental crayfish plague Aphanomyces astaci. In this study we analyzed both at a regional and at a local scale factors determining native and alien crayfish distribution in an area where the species Procambarus clarkii is currently spreading. We aim to understand which ...
Assessing the Feasibility of Managed Aquifer Recharge for Irrigation under Uncertainty
Additional storage of water is a potential option to meet future water supply goals. Financial comparisons are needed to improve decision making about whether to store water in surface reservoirs or below ground, using managed aquifer recharge (MAR). In some places, the results of cost-benefit analysis show that MAR is financially superior to surface storage. However, uncertainty often exists a...


Astin B, a cyclic pentapeptide from Aster tataricus, induces apoptosis and autophagy in human hepatic L-02 cells
Astins (including astin B) are a class of halogenated cyclic pentapeptides isolated from the medicinal herb of Aster tataricus. However, our previous works showed that the herbal medicine was hepatotoxic in vivo, and a toxicity-guided isolation method led to the identification of a cyclopeptide astin B. Astin B is structurally similar to cyclochlorotine, a well-known hepatotoxic mycotoxin. Thus...
Symmetrical diiodinated squaraine as an efficient photosensitizer for PDT applications: Evidence from photodynamic and toxicological aspects
Photodynamic therapy (PDT) is emerging as a promising non-invasive treatment for cancers. It involves three key components; a photosensitizer, light and tissue oxygen. Even though several photosensitizers have been investigated for their use in PDT, they have several disadvantages and hence the search for more effective sensitizers has become important in recent years. The dye selected in our s...


Litter Fall Dynamics of Restored Mangroves (Rhizophora mucronata Lamk. and Sonneratia alba Sm.) in Kenya
Mangrove forests are active carbon sinks and important for nutrient cycling in coastal ecosystems. Restoration of degraded mangrove habitats enhances return of ecosystem goods and services, including carbon sequestration. Our objective was to assess the restoration of primary productivity of reforested mangrove stands in comparison with natural reference stands in Gazi Bay, Kenya. Litter fall d...
The place of agricultural sciences in the literature on ecosystem services
We performed a quantitative and qualitative analysis of the scientific literature on ecosystem services in order to help tracing a research agenda for agricultural sciences. The ecosystem services concept now lies at the heart of current developments to address global environmental change. Do agricultural sciences generate knowledge that covers this emerging theme? An analysis of scientific pro...

Ecosystem services assessment at Steart Peninsula, Somerset, UK
A systemic valuation was undertaken of marginal changes in ecosystem services assessed as likely to result from the Steart Coastal Management project, some in monetary terms and others semi-quantified. The Steart Coastal Management project entails allowing seawater once again to inundate formerly defended farmland, including modifications to the landform of to assist the re-creation of a range ...
Developing spatial biophysical accounting for multiple ecosystem services
Ecosystem accounting is receiving increasing interest as a way to systematically monitor the conditions of ecosystems and the ecosystem services they provide. A critical element of ecosystem accounting is understanding spatially explicit flows of ecosystem services. We developed spatial biophysical models of seven ecosystem services in a cultural landscape (Limburg province, the Netherlands) in...

Predator decline leads to decreased stability in a coastal fish community
Fisheries exploitation has caused widespread declines in marine predators. Theory predicts that predator depletion will destabilise lower trophic levels, making natural communities more vulnerable to environmental perturbations. However, empirical evidence has been limited. Using a community matrix model, we empirically assessed trends in the stability of a multispecies coastal fish community o...
Environmental effects on the reproduction and fecundity of the introduced calcareous sponge Paraleucilla magna in Rio de Janeiro, Brazil
The calcareous sponge Paraleucilla magna (Porifera, Calcarea) has been the subject of several studies in the last decade. It was first described along the Brazilian coast, where it is considered cryptogenic, and was subsequently found in the Mediterranean, where it is considered invasive. The wide artificial distribution of this species allows us to compare different aspects of the biology of a...

The rise of Laminaria ochroleuca in the Western English Channel (UK) and comparisons with its competitor and assemblage dominant Laminaria hyperborea
The distribution of species is shifting in response to recent climate change. Changes in the abundance and distributions of habitat-forming species can have knock-on effects on community structure, biodiversity patterns and ecological processes. We empirically examined temporal changes in the abundance of the warm-water kelp Laminaria ochroleuca at its poleward range edge in the Western English...
Genomic exploration and molecular marker development in a large and complex conifer genome using RADseq and mRNAseq
We combined Restriction site Associated DNA sequencing (RADseq) using a hypomethylation-sensitive enzyme and messenger RNA sequencing (mRNAseq) to develop molecular markers for the 16 Gigabase genome of Cedrus atlantica, a conifer tree species. With each method, Illumina® reads from one individual were used to generate de novo assemblies. SNPs from the RADseq dataset were detected in a panel o...
A comparison of SNP and microsatellite markers for analysis of parentage and kinship in a cooperatively breeding bird
The development of genetic markers has revolutionized molecular studies within and among populations. Although poly-allelic microsatellites are the most commonly used genetic marker for within-population studies of free-living animals, bi-allelic single nucleotide polymorphisms, or SNPs, have also emerged as a viable option for use in non-model systems. We describe a robust method of SNP discov...
Cuticular Extracts from Acromis sparsa (Coleoptera: Cassidinae) Mediate Arrestment Behavior of the Commensal Canestriniid Mite Grandiella rugosita
Astigmatid mites in the family Canestriniidae are often closely associated with tortoise leaf beetles (Chrysomelidae: Cassidinae). For example, the survival of the commensal canestriniid mite Grandiella rugosita depends on dispersal to the cassidine beetle Acromis sparsa. Here, we tested whether the beetle cuticle provides chemical cues for host recognition for G. rugosita. In two-choice assays...
