  Chondrichthyan habitat characteristics and composition in respect to life cycle
Part of risk assessment is evaluating fish overlap with fisheries, where fish distribution influenced by habitat use. Synthesised published observations of habitat use for different life history stages, and hypothesise associated catch composition in terms of fish sex, size, + maturity. Some life stages and habitats could be identified.

  Pediatric brain tumour wars: A new hope
 

Brain tumours are problematic to treat with chemotherapy and surgery isn’t always possible. Radiotherapy can be quite effective but is not an option in infants which causes an increase in mortality and creates a void in viable treatment options. New frontiers might offer hope the future; here are the exciting few on the vanguard.

Biodiversity research in Indonesia: Marrying science with practical conservation
 

I present Borneo Nature Foundation’s work in the Sabangau Landscape, Central Kalimantan, Indonesia. We combine rigorous scientific research with community-engagement and grass-roots conservation actions to protect ~5400km2 of tropical peat-swamp forest, home to threatened species including the Bornean orangutan and Sunda pangolin.

Red or Dead-honest signalling and automimicry in an aposematic insect
 

Can birds tell how bad a moth will taste from its colour? No, female wood tiger moths vary in colour, but this colour is not an honest signal of the strength of their chemical defences. Instead birds may be able to smell how bad they are.

  Bloodworms are driving lake’s respiration up
 

Bloodworms (larvae of Chironomidae midges of certain genera) are important ecosystem engineers in lakes, where their burrowing and burrow ventilation are modifying fluxes of nutrients, oxygen. We have shown that presence of larvae is increasing lake sediment respiration by 4.5 times, and the effects are increasing within gradient of temperatures.

High escape performance in mutualistic cleaner fish despite privileged relationship with predators
 

On the reef, predators regularly visit cleaner fish to get their ectoparasites removed but show no interest in eating them. Despite this privileged relationship, our comparisons with closely related species show that cleaners have maintained a high escape performance. I will discuss which aspects of cleaners’ ecology might select for a fast escape.

Nutrient dynamics in decomposing dead wood in the context of wood eater requirements: the ecological stoichiometry of saproxylophagous insects
 

Although dead wood is rich in sugars, it lacks other nutrients, preventing the development of saproxylophages. However, fungal transport can shape the nutrient dynamics during the initial stages of dead wood decay by rearranging the concentrations of nutrients in wood, allowing saproxylophages to grow, develop and mature.

Plant–insect interactions: the role of ecological stoichiometry
 

The energy budget of organisms is a primary factor used to generate hypotheses in ecosystem ecology and evolutionary theory. Stoichiometric balance is equally important: inconsistency between the chemical composition of the consumer’s tissues and that of its food sources influences the consumer’s fitness and shapes plant–herbivore interactions.
