Article
Whether animals can actively avoid food contaminated with harmful compounds through taste is key to assess their ecotoxicological risks. Here, we investigated the ability of honey bees to perceive and avoid food resources contaminated with common metal pollutants known to impair behaviour at low concentrations. In laboratory assays, bees did not di...

Environmental stressors have sublethal consequences on animals, often affecting the mean of phenotypic traits in a population. However, potential effects on variance are poorly understood. Since phenotypic variance is the basis for adaptation, any influence of stressors may have important implications for population resilience. Here we explored thi...
Article
Giant clams (Tridacninae) are an ecologically important species in coral reef habitats across the Indo-Pacific. Numerous examples of giant clam population declines of varying degrees of severity have been documented since the 1970s. These have been attributed to several reasons, such as overexploitation in regional fisheries and ornamental trades,...
Article
Competition for space on coral reefs is fierce, however when external natural and anthropogenic drivers disproportionately benefit certain organisms, reefs can quickly be conquered. Sponges in particular, have been shown to be competitive benthic colonisers and incidences of their epibiosis on scleractinian corals in the Indo-Pacific have been grow...
Article
Concrete cubic frames and decommissioned steel naval vessels have been deployed in Thailand liberally to act as artificial substrates for coral restoration and marine recreation. We assessed recruitment at such substrate types at Koh Tao, Gulf of Thailand, and compared the community structure of scleractinian corals between artificial substrates an...
Thesis
Honey bees are crucial pollinators. A plethora of environmental stressors, such as agrochemicals, have been identified as contributors to their global decline. Especially, these stressors impair cognitive processes involved in fundamental behaviours. So far however, virtually nothing is known about the impact of metal pollutants, despite their know...

Whether animals can actively avoid food contaminated with harmful compounds through taste is key to understand their ecotoxicological risks. Here, we investigated the ability of honey bees to perceive and avoid food resources contaminated with common metal pollutants known to impair their cognition at low concentrations (lead, zinc and arsenic). In...
Article

Improved access to field survey infrastructure throughout South-East Asia has allowed for a greater intensity of biodiversity surveys than ever before. The rocky bottoms and coral reef habitats across the region have been shown to support some of the highest sea slug biodiversity on the planet, with ever increasing records. During the past ten year...
Article
Environmental pollutants can exert sublethal deleterious effects on animals. These include disruption of cognitive functions underlying crucial behaviours. While agrochemicals have been identified as a major threat to pollinators, metal pollutants, which are often found in complex mixtures, have so far been overlooked. Here we assessed the impact o...
Article
Full-text available
Pollutants can have severe detrimental effects on insects, even at sublethal doses, damaging developmental and cognitive processes involved in crucial behaviours. Agrochemicals have been identified as important causes of pollinator declines, but the impacts of other anthropogenic compounds, such as metallic trace elements in soils and waters, have...
Article
Full-text available
The current decline of invertebrates worldwide is alarming. Several potential causes have been proposed but metal pollutants, while being widespread in the air, soils and water, have so far been largely overlooked. Here, we reviewed the results of 527 observations of the effects of arsenic, cadmium, lead and mercury on terrestrial invertebrates. Th...

Article
Full-text available
Research in recent years have provided rapid advances in biogeographic and taxonomic documentation of sea slugs around the world. However, efforts are lacking in surveying most coastlines and habitats in South-East Asia. Recent studies from the Gulf of Thailand have indicated that a wealth of unexplored sea slug diversity and ecology may be gained...

In 2018, the government of Escalante city, Philippines, sought to improve the sustainability of marine resource utilisation within Escalante waters as part of a larger overhaul of sustainable resource use within its borders. As part of this effort, Conservation Diver was approached to provide an ecological assessment of species richness and ecosyst...
Article
Full-text available
Recent studies revealed that reef corals can eat large-sized pelagic and benthic animals in addition to small planktonic prey. As follow-up, we document natural ingestion of sea slugs by corals and investigate the role of sacoglossan sea slugs as possible prey items of scler-actinian corals. Feeding trials were carried out using six sacoglossan spe...

Chapter
Over the past decades, research on insect cognition has made considerable advances in describing the ability of model species (in particular bees and fruit flies) to achieve cognitive tasks once thought to be unique to vertebrates, and investigating how these may be implemented in a miniature brain. While this lab-based research is critical to unde...

Chlorpyrifos is an organophosphate pesticide used around the world to protect food crops against insects and mites. Despite guidelines for chlorpyrifos usage, including precautions to protect beneficial insects, such as honeybees from spray drift, this pesticide has been detected in bees in various countries, indicating that exposure still occurs....

Question
I'm interested in the international guidelines for heavy metals in food/water (drinking or irrigation) as set by the WHO/FAO, or local guidelines for contents in the environment (soil for instance). What are the consequences if the values measured are above the guidelines? It's unclear to me whether those standards are just 'desired thresholds' or whether one could face legal action?
Thanks for your help.
Question
Hi, I could use your help to analyze with R software my data investigating the effects of environmental parameters and parasite species on growth rates.
I measured the length and width of 3 species of plants every 2 weeks for 6 months. I did it in 2 different sites. In each site, I had 6 quadrats as a unite of replication, with 4 plants of each species per quadrat.
As environmental variables, I have: the temperature at each site for the whole period and the relative covers of two unwanted plant species (assessed every 2 weeks).
First of all, should I work on the raw data of length and width or on growth rates (mm/day) or on another variable combining those two apparied measures?
Next, how to test the effect of the time and of the 3 environmental variables (temperature, growth unwanted plant 1, growth unwanted plant 2)? I was thinking of doing GLMMs and maybe use a multi model inference procedure (like MuMin) to select the model taking into account the variables really having an effect?
Thanks a lot for your advice.
Question
Dear all,
I'm looking for a way to statistically compare species composition between sites. I have the abundance of 42 species for 21 sites belonging to 4 different categories. I will also soon have GPS data giving me the distance between sites.
I basically want to see if there is any similarity in term of ecological composition between my sites and between categories and also if any species indicators (or combination of them) come out for each sites or for each category of sites.
So far, I've tried to compute Bray Curtis matrix (vegan package on R) giving me dendrogram of similarity and play around with Indicspec package, but I'm definitely out of my confort zone with that kinds of tests. Once I have the GPS data, I'd like to include those informations in the analyzes, but I have no clue on how to do it (Mantel correlation?).
Any inputs on what to do and how to do it would be much appreciated.
Cheers
Question
I'm attempting a biodiversity inventory of numerous invertebrate species at two locations in the Indo-Pacific (Gulf of Thailand and Philippines), but I've not been able to find comprehensive ressources for the purpose of cowrie identification. Are there any papers or guides that might be available to assist in this? If not, what is the best way for me to accurately identify species we're finding? Thank you very much.
