Chemical residues in declining commercial honey bee coloniesNARA Subscribed
Protecting pollinators and our food supply: understanding and managing threats to pollinator healthNARA Subscribed
Global pollinator declines threaten food production and natural ecosystems. The drivers of declines are complicated and driven by numerous factors such as pesticide use, loss of habitat, rising pathogens due to commercial bee keeping and climate change. Halting and reversing pollinator declines will require a multidisciplinary approach and international cooperation. Here, we summarize 20 presentations given in the symposium ‘P...
Certification of açaí agroforestry increases the conservation potential of the Amazonian tree floraNARA Subscribed
The harvesting of açaí berries (palm fruits from the genus Euterpe ) in Amazonia has increased over the last 20 years due to a high local and global market demand and triggered by their widely acclaimed health benefits as a ‘superfood’. Although such increase represents a financial boom for local communities, unregulated extraction in Amazonia risks negative environmental effects including biodiversity loss through açai intens...
Presumptive horizontal symbiont transmission in the fungus‐growing termite Macrotermes natalensisNARA Subscribed
All colonies of the fungus‐growing termite Macrotermes natalensis studied so far are associated with a single genetically variable lineage of Termitomyces symbionts. Such limited genetic variation of symbionts and the absence of sexual fruiting bodies (mushrooms) on M. natalensis mounds would be compatible with clonal vertical transmission, as is known to occur in Macrotermes bellicosus . We investigated this hypothesis by ana...
The western Indian Ocean seahorse Hippocampus fuscus is recorded for the first time in the Mediterranean. Its presence there is probably due to migration from the Red Sea via the Suez Canal.
No seasonal pattern was found in total swimbladder weight, sonic muscle weight, or spinal sonic motor nucleus neuron soma size of the oyster toadfish Opsanus tau , indicating that additional nonsteroidal factors are also involved in the development of the toadfish sonic neuromuscular system.
