Peacekeeping creatures help maintain woodland diversity
Common woodland creatures, including woodlice, millipedes and worms, can help ensure the survival of weaker species of woodland fungi, according to new research from Cardiff University. The findings reveal that, by feeding on the most combative fungi, invertebrates ensure that less competitive species are not entirely destroyed or digested. (2011-09-20)

Sea worms and jellyfish treat cancer and kill insects
Scientists of the Pacific Institute of Bioorganic Chemistry (PIBOC) of the Far Eastern Branch of the Russian Academy of Sciences (FEB RAS) and the Far Eastern Federal University (FEFU) found out marine invertebrates living in Troitsa Bay, the Sea of Japan, contain biologically active compounds with strong antitumor and antimicrobial properties, and also capable of killing insects. An article on that was published in the Russian Journal of Marine Biology. (2019-02-14)

Litter provides habitat for diverse animal communities in rivers, study finds

Insects Provide Clues About Bodies Underwater
Simon Fraser University researcher Niki Macdonell says the eight rotting pig carcasses she'll pull from streams and lakes in local forests next month hold important clues to deaths that occur in freshwater. With virtually no research in the field to draw on, Macdonell, says pathologists are (1997-10-22)

Abandoning pastures reduces the biodiversity of mountain streams
The abandonment of high-altitude mountain pastures and the climatic changes that are causing woodland boundaries to extend ever higher, may potentially result in the reduction of the number and variety of invertebrates living in mountain streams. Eurac Research ecologists have compared 15 streams and found that in streams running through extensive meadows with grazing animals -- regardless of elevation -- biodiversity is greater. The study was published in the renowned international journal Freshwater Biology. (2020-01-07)

Research shows catastrophic invertebrate extinction in Hawai'i and globally
A team of researchers recently published the first rigorous assessment of extinction of invertebrates in Hawai`i. In a companion study the team addressed invertebrate extinction globally. Based on their findings, the researchers show that the suspected biodiversity crisis is real and stressed the need to include assessments of invertebrates in order to obtain a more realistic picture of the current situation, known widely as the 'sixth mass extinction.' (2015-08-10)

New study predicts worldwide change in shallow reef ecosystems as waters warm
A new study based on the first global survey of marine life by scuba divers has provided fresh insights into how climate change is affecting the distribution of marine life. The research published in the journal Science Advances predicts that as the oceans warm fish -- which appear to be superior predators in warm water -- will extend their ranges away from the equator and cause a decline in the diversity of invertebrates such as crabs, lobsters, sea urchins and whelks. (2017-10-18)

Ants show left bias when exploring new spaces
Unlike Derek Zoolander, ants don't have any difficulty turning left. New research from the University of Bristol, UK published today in Biology Letters, has found that the majority of rock ants instinctively go left when entering unknown spaces. (2014-12-23)

New procedure repairs severed nerves in minutes, restoring limb use in days or weeks
American scientists believe a new procedure to repair severed nerves could result in patients recovering in days or weeks, rather than months or years. The team used a cellular mechanism similar to that used by many invertebrates to repair damage to nerve axons. Their results are published today in the Journal of Neuroscience Research. (2012-02-03)

World of viruses uncovered
A groundbreaking study of the virosphere of the most populous animals has uncovered 1,445 viruses, revealing people have only scratched the surface of the world of viruses -- but it is likely that only a few cause disease. The meta-genomics research, a collaboration between the University of Sydney and the Chinese Centre for Disease Control and Prevention was made possible by technology that also provides a powerful new way to determine what pathogens cause human diseases. (2016-11-23)

'Wrong-way' migrations stop shellfish from escaping ocean warming

The complex fate of Antarctic species in the face of a changing climate
Researchers from the University of Plymouth and the British Antarctic Survey have presented support for the theory that marine invertebrates with larger body size are generally more sensitive to reductions in oxygen than smaller animals, and so will be more sensitive to future global climate change. However, evolutionary innovation can to some extent offset any respiratory disadvantages of large body size. (2019-06-16)

Popular seafood species in sharp decline around the world
The first-ever global study of long-term trends in the population biomass of exploited marine fish and invertebrates for all coastal areas on the planet. (2020-07-21)

Soil and sediment contamination assessment more accurate
Prolonged exposure of soil and sediment invertebrates to toxic polycyclic aromatic compounds has large and unpredictable effects on the life cycle of these species, concludes Dutch researcher Miriam Leon Paumen. These chronic effects can be very different from the effects of short-term exposure to PACs. Therefore, assessments of soil and sediment contamination are more reliable when they are based on the effects of prolonged exposure of soil and sediment fauna to toxic substances. (2009-03-11)

Bumblebees recognize objects through sight and touch, a complex cognitive feat
Demonstrating an unprecedented degree of cognitive complexity in an insect, researchers report that bumblebees are capable of recognizing objects across senses. (2020-02-20)

Underground gourmet: Selected terrestrial cave invertebrates and their meal preferences
Doubting whether cave invertebrates feed on just anything they can find in the harsh food-wise environment underground, Dr. Jaroslav Smrz's team conducted a research in Slovakian and Romania caves. They studied a number of microwhip scorpions, oribatid mites, millipedes, springtails and crustaceans and their gut content. As a result it was concluded that there is an evident nutritional specialization among the selected groups. The paper is available from the open-access journal Subterranean Biology. (2015-08-10)

Invertebrate numbers nearly halve as human population doubles
Invertebrate numbers have decreased by 45 percent on average over a 35 year period in which the human population doubled, reports a study on the impact of humans on declining animal numbers. This decline matters because of the enormous benefits invertebrates such as insects, spiders, crustaceans, slugs and worms bring to our day-to-day lives, including pollination and pest control for crops, decomposition for nutrient cycling, water filtration and human health. (2014-07-24)

Mice with fewer insulin-signaling receptors don't live longer
