Ecology (Biology & Medicine)

Close-up of a rock slab. The rock is dark gray to black. A complex pattern of light gray, almost white, branching, and interconnected structures is visible across the surface of the slab. These structures resemble a network or a colony of small, interconnected organisms. A small, light-colored, somewhat circular area near the center appears to be different from the surrounding patterns, potentially a part of fossilized remains embedded in the rock matrix. A scale bar,in the lower right corner of the image indicates about 1 centimeter.The edges of the slab are irregular and broken. The lighting is even, casting no significant shadows. The rock slab is presented against a plain white background.

Analysis of nitrogen isotopes provides evidence of the earliest known photosymbiosis in corals of the Devonian more

Pit-building venom mixers

A complex venom system allows antlions to overpower large prey more

Post from Perth, Australia

Jozefien Van de Velde from the Max Planck Institute for Plant Breeding Research in Cologne traveled to Australia for two months in search of frogs in the outback. This was no easy task, as her study subjects are nocturnal, hide underground in dry conditions, and only emerge after heavy rain. more

New Insights into the Dynamics of Microbial Communities

Under certain circumstances, the abundance of plankton species changes continuously without one species becoming permanently dominant more

Bacteria in the Arctic seabed are active all year round

The bacterial community in Arctic sediments is taxonomically and functionally very stable more

2023 – a year of climate extremes

The devastating storms, rainfall, heatwaves and droughts of the past year have become more likely and more severe as a result of global warming more

Different olfactory worlds of female and male silkmoths

Female moths primarily use their sense of smell to find the best host plants on which to lay their eggs more

Beewolf symbiosis: Protective shield for allies

The digger wasps protect their symbionts from toxic nitric oxide released by their eggs to kill pathogens more

Symbiotic fungi produce attractants for bark beetles

When metabolizing spruce bark, the insect’s fungal partners release volatile compounds that bark beetles  recognize through specialized olfactory sensory neurons more

The Mona Lisa effect: Eyespots deter predators that approach from different directions

Experiments with chicken chicks and artificial peacock butterflies prove that predators are intimidated by eyespots more

Scientists unearth another brain-shrinking mammal

A study of moles reveals that cold weather – not lack of food – drives the rare phenomenon of reversible brain shrinkage in mammals more

“The only things you want to conserve are the things you know”

Jana Wäldchen has played a key role in developing the plant identification app, Flora Incognita. We discussed with her how being able to identify different plants contributes to species diversity, which plant species are particularly under threat and how non-native species are suppressing local plants more

A Stickleback - Full of Worms

Around 40 percent of all species on Earth are parasitic – apparently a highly successful way of life. Even a fish such as the three-spined stickleback is plagued by up to 25 different parasites. more

The irresistible fragrance of dying vinegar flies

Bacterial pathogens cause infected flies to produce more sex pheromones and so expand their deadly reach more

A parasite involved in the plant alarm system

Host plants communicate warning signals through a parasite network, when insects attack more

Oil as energy source for deep-sea creatures

Scientists discover mussels and sponges in the deep sea which can thrive on oil with the help of symbiont bacteria more

Reptile vocalization is surprisingly flexible

Phenotypic plasticity of gecko calls reveals the complex communication of lizards more

Bergamotene—alluring and lethal for <em>Manduca sexta</em>

The volatile compound bergamotene increases the moths’ pollination success and protects tobacco leaves against their voracious offspring more
