Light pollution disrupts crickets' circadian rhythms and threatens their reproduction

Further research on crickets reveals that light pollution throws them out of sync, impairs their reproductive ability, and threatens their continued existence.

Research in the Negev: New water points improved the genetic diversity of wild animals

Researchers at Ben-Gurion University found that increasing the number of water sources from one to three increased the proportion of males participating in reproduction, offering a simple and non-invasive conservation tool.

Tiny ants have been recorded cleaning up large ants in the Arizona desert

Smithsonian researchers have documented for the first time behavior reminiscent of "cleaner fish" in the sea: small ants climb onto large harvester ants and clean their jaws as well

Paul Ehrlich, author of “The Population Bomb,” dies at 93

The Stanford University biologist and environmentalist was one of the most influential and controversial voices in environmental science: a leading scientist in the field of ecology, who warned about population pressure on natural systems many years before the climate crisis became a reality.

Man is not always the scariest creature in the forest.

New research shows that wild animals distinguish between hunters and fishermen and tourists and researchers, and adjust their level of fear to the type of threat and its perceived magnitude.

Neither a tree nor a generous one – the climbing plant that deceives birds

New research reveals that the Dioscorea melanophyma plant has lost its ability to reproduce through seeds – but has developed black, berry-like bells. Birds accidentally swallow them and spread them hundreds of miles away.

Fungi dominated the Earth hundreds of millions of years before plants.

New research reveals that fungi created ancient soils and prepared the continents for the arrival of plants, through early collaboration with algae

The light that extinguishes the crickets' song

When the night is no longer dark, crickets' sexual communication is compromised. Studies in Israel reveal the ecological toll that night lighting takes on crickets and explain how we can help them

Even birds can't escape global warming

A Yale University study examines the movements of 406 migratory bird species and finds that most birds are not moving fast enough to keep up with rising temperatures.

Which anemone is tastier? The hidden battle between colors in nature

Why are there red anemones alongside purple, pink, and white anemones? Is this a random whim of nature, or perhaps colors that help the flowers evade hungry caterpillars? New research aims to solve the mystery

Nests against invaders: humane control of species

An Israeli industrial designer has developed a smart nest that prevents the development of minnow eggs without harming the bird - has the solution been found to eradicate the notorious invasive bird?

Different species of trees that grow next to each other create a new tree - a cage - that combines the advantages of both species, and is able to cope with the rapid changes in the environment. An exciting new Israeli study

Defeat the system: the creative ways to eradicate the spread of the bluish system

The bluish acacia, an invasive tree brought to Israel from Australia, is spreading rapidly and threatening the local ecosystems. New research suggests innovative solutions, including biological control using weevils, chemical control, and mechanical methods such as disinfection

The complex language of birds

Studies from Israel and abroad have found that birds do not chirp only for courtship purposes, and that they have a complex language that affects their choice of who to communicate with and how - even during migration

Photo 4: The life cycle of the blooming sea lily Edwardsiella carnea. a. Mature male and female polyps release gametes into the water column. b. Free-swimming planula formed after fertilization. c. The planula infects the comb host Mnemiopsis leidyi and develops into a worm-like parasitic stage. d. Planula after the parasite stage exits the comb host to the water column (e), where it can either settle on the sea floor (f) and develop into a polyp (a) or infect another comb host or a scyphozoan host such as Rhopilema nomadica or Rhizostoma pulmo (hypothetical parasite spillover) (gh) . A planula after the parasite stage may leave the scyphozoic host and move through the water column (i), where it may settle on the sea floor (f) and develop into a polyp. The dashed line represents an alternative route.

Jellyfish under attack: Researchers have found parasitic sea lilies in jellyfish for the first time

Researchers have discovered for the first time the existence of parasitic planoles (sort of larvae) of the sea lily that grows in jellyfish in the Mediterranean Sea that allow the sea lily to spread beyond the immediate environment, a finding that may affect ecosystems

A new Israeli study examined how the presence of wolves affects the activity of large mammals. The findings reinforce the importance of the predator in maintaining the integrity of the ecosystem

Researchers from Ben Gurion University offer an innovative explanation for this unique behavior of the fairy circles phenomenon: a combination of phenotypic adaptation at the level of the individual plant, by deepening the roots of the plants into more moist soil layers,

Corals from the Red Sea have invaded Israel's Mediterranean coast

Until now, the low temperatures of the Mediterranean water in winter have been a barrier to the arrival of tropical corals. The establishment of the Dendronaphtia we found indicates that at least last winter, the waters of the Mediterranean Sea were warmer than before
