The venom preceded the stinger: Genomic studies shed light on the origins of bee venom      (via sciencedaily.com)     Original source 

Bees, wasps and ants belong to the Hymenoptera order and inject a whole cocktail of venomous ingredients when they sting. Despite their tremendous ecological and economic importance, little was previously known about the origins of their venom. Through extensive genomic studies, a team of researchers has now discovered that typical venomous components were already present in the earliest ancestors of Hymenoptera and must therefore have evolved before the stingers of bees and other insects. What's more, and contrary to previous assumptions, the gene for the venom melittin is found solely in bees.

Fish ecologist's research indicates need to conserve iconic migratory snook in Mexico      (via sciencedaily.com)     Original source 

Biologists investigated the snook’s almost 400-mile migration up into the rainforest habitat of the Usumacinta River. They have found that the snook, which connect aquatic food webs and support fisheries, spawn and start their lives in coastal nursery habitats before moving into river habitats that offer an array of food resources.

Pioneering research method reveals bluefin tuna's fate      (via sciencedaily.com)     Original source 

The Mediterranean spawning grounds of Bluefin tuna -- the largest tuna and one of the most powerful fish in the sea -- are under threat, due to rising sea temperatures. A pioneering research method to decode bluefin 'otoliths' (a stony tissue found in their ear) has determined the threshold sea temperature at which bluefin thrive to be 28 degrees Celsius.

How do temperature extremes influence the distribution of species?      (via sciencedaily.com)     Original source 

As the planet gets hotter, animal and plant species around the world will be faced with new, potentially unpredictable living conditions, which could alter ecosystems in unprecedented ways. A new study investigates the importance of temperature in determining where animal species are currently found to better understand how a warming climate might impact where they might live in the future.

First comprehensive look at effects of 2020-2021 California megafires on terrestrial wildlife habitat      (via sciencedaily.com)     Original source 

In 2020 and 2021, California experienced fire activity unlike anything recorded in the modern record. When the smoke cleared, the amount of burned forest totaled ten times more than the annual average going back to the late 1800s. We know that wildlife in western forests evolved with changing habitat and disturbances like wildfire. Each species responds differently, some benefiting from openings, others losing critical habitat. What we don't know is how increasing fire severity at large scales is impacting their habitat and survival, because many species are not adapted to these types of 'megafires.'

Curators and cavers: How a tip from a citizen scientist led to deep discoveries in Utah's caves      (via sciencedaily.com)     Original source 

Scientists and colleagues from Utah's caving community have published the first research from their collaborative fieldwork effort deep in Utah's caves. The journal's feature article reveals why caves make such compelling research archives; what was uncovered in Boomerang Cave in northern Utah; why skeletal remains provide new access to hard-to-get data from the recent past; and offers a new zoological baseline for mammalian changes in an alpine community.

Deep-sea mining and warming trigger stress in a midwater jellies      (via sciencedaily.com)     Original source 

The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.

Microbiome development: Bacteria lay the foundations for their descendants      (via sciencedaily.com)     Original source 

The microbiome (the symbiotic community of microbial organisms of a host) is of existential importance for the functioning of every plant and animal, including human beings. A research team has now used the example of the sea anemone Nematostella vectenis to investigate how the microbiome develops together with the host. The researchers describe that the bacterial community is primarily controlled by the host organism during the early stages of life, while bacteria-bacteria interactions play the lead role in subsequent development.

Scientists have solved the damselfly color mystery      (via sciencedaily.com)     Original source 

For over 20 years, a research team has studied the common bluetail damselfly. Females occur in three different color forms -- one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic color variation that is shared between several species arose through changes in a specific genomic region at least five million years ago.

Like the phoenix, Australia's giant birds of prey rise again from limestone caves      (via sciencedaily.com)     Original source 

Australia's only vulture, and a fearsome extinct eagle, are among the earliest recorded birds of prey from the Pleistocene period more than 50,000 years ago -- and now researchers are bringing them to 'life' again.    Along with new scientific information, a bold new pictorial reconstruction of a newly named eagle and the only known Australian vulture will be unveiled at the World Heritage-listed Naracoorte Caves in South Australia's Limestone Coast this month.
