New study identifies bird species that could spread ticks and Lyme disease
A new study published in the journal Global Ecology and Biogeography used machine learning to identify bird species with the potential to transmit the Lyme disease bacterium (Borrelia burgdorferi) to feeding ticks. The team developed a model that identified birds known to spread Lyme disease with 80% accuracy and flagged 21 new species that should be prioritized for surveillance. (2021-01-27)

New malaria mosquito is emerging in African cities
Larvae of a new malaria mosquito species are abundantly present in water containers in cities in Ethiopia. The mosquito, Anopheles stephensi, is the main malaria mosquito in India but only appeared on the African continent a few years ago. It has now been found in cities and towns in urban settings in Ethiopia, Sudan, and Djibouti. Malaria can become an increasing problem for urban areas in Ethiopia and elsewhere in Africa.

When push comes to shove, what counts as a fight?
Biologists often study animal sociality by collecting observations about behavioral interactions. These interactions can be things like severe or minor fights, cooperative food sharing or grooming. But to analyze animal behavior, researchers need to make decisions about how to categorize and code these interactions. That gets tricky. (2021-01-26)

Scientists show impact of human activity on bird species
Scientists have shown where bird species would exist in the absence of human activity under research that could provide a new approach to setting conservation priorities. (2021-01-25)

Microbiome Search Engine 2 helps researchers explore microbiome space
To correlate the newly developed microbiomes with existing data sets, researchers from the Qingdao Institute of BioEnergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) and their collaborators developed the Microbiome Search Engine 2 (MSE 2). (2021-01-22)

A quarter of known bee species haven't appeared in public records since the 1990s
Researchers at the Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) in Argentina have found that, since the 1990s, up to 25% of reported bee species are no longer being reported in global records, despite a large increase in the number of records available. While this does not mean that these species are all extinct, it might indicate that these species have become rare enough that no one is observing them in nature. The findings appear January 22 in the journal One Earth. (2021-01-22)

Fish sex organs boosted under high-CO2
Research from Australia has found that some species of fish will have higher reproductive capacity because of larger sex organs, under the more acidic oceans of the future. (2021-01-21)

Snake sex chromosomes say less about sex and more about survival
A new study looks to snakes to broaden our understanding of what makes a gene able to survive on a sex-specific chromosome. Comparing surviving genes on snake sex-specific chromosomes to those that are lost to the ravages of time can teach scientists about the evolutionary pressures that shaped sex chromosomes as we know them today.

Study shows how network of marine protected areas could help safeguard Antarctic penguins
New research led by BirdLife International, the University of East Anglia (UEA) and British Antarctic Survey highlights how a proposed network of marine protected areas could help safeguard some of the most important areas at sea for breeding Antarctic penguins. (2021-01-20)

Climate-related species extinction possibly mitigated by newly discovered effect
Changes in climate that occur over short periods of time influence biodiversity. For a realistic assessment of these effects, it is necessary to also consider previous temperature trends going far back into Earth's history. Researchers from the University of Bayreuth and the University of Erlangen-Nuremberg show this in a paper for ''Nature Ecology and Evolution''. (2021-01-20)

Bonobos, chimpanzees, and oxytocin
Kyoto University researchers analyze the effects of the hormone oxytocin in our closest primate cousins, bonobos and chimpanzees by tracking their eye movement -- a important indicator of social interaction. Similar to other mammals, oxytocin increases eye contact in bonobos. However, the opposite effect is observed in chimpanzees. Therefore, oxytocin could play a modulating role in the social evolution of the two species. (2021-01-20)

Indigenous lands: A haven for wildlife
Indigenous peoples' lands may harbour a significant proportion of threatened and endangered species globally, according to University of Queensland-led research. (2021-01-20)

50 million-year-old fossil assassin bug has unusually well-preserved genitalia
The fossilized insect is tiny and its genital capsule, called a pygophore, is roughly the length of a grain of rice. It is remarkable, scientists say, because the bug's physical characteristics -- from the bold banding pattern on its legs to the internal features of its genitalia -- are clearly visible and well-preserved. Recovered from the Green River Formation in present-day Colorado, the fossil represents a new genus and species of predatory insects known as assassin bugs. (2021-01-19)

With a little help from their friends, older birds breed successfully
The offspring of older animals often have a lower chance of survival because the parents are unable to take care of their young as well as they should. The Seychelles warbler is a cooperatively breeding bird species, meaning that parents often receive help when raising their offspring. A study led by biologists from the University of Groningen shows that the offspring of older females have better prospects when they are surrounded by helpers. (2021-01-19)

'Babysitters' provide boost to offspring of elderly birds
Young Seychelles warblers fare better if their elderly parents have help raising them, according to new research from the University of East Anglia (UEA) and the University of Groningen. Seychelles warblers, a cooperatively breeding species of songbird that lives in small family groups, share the care of young between parents and helpers. This collaboration can compensate for a decline in the ability of elderly parents to provide sufficient care, the researchers found. (2021-01-18)

Of the honey bee dance
Honey bees are unique in that they not only alert their nestmates but have also evolved a symbolic communication in the form of a dance - a waggle dance. (2021-01-18)

Guppies have varying levels of self-control
Just like humans trying to stick to New Year's resolutions, guppies have varying levels of self-control, a new study shows. (2021-01-15)

Micro-climate moulds and reshapes northern insect communities, herbivory and predation
Climate and changes in it have direct impacts on species of plant and animals - but climate may also shape more complex biological systems like food webs. Now a research group from the University of Helsinki has investigated how micro-climate shapes each level of the ecosystem, from species' abundances in predator communities to parasitism rates in key herbivores, and ultimately to damage suffered by plants. The results reveal how climate change may drastically reshape northern ecosystems. (2021-01-14)

CCNY's David Lohman finds Asian butterfly mimics different species as defense mechanism
Many animal and insect species use Batesian mimicry - mimicking a poisonous species - as a defense against predators. The common palmfly, Elymnias hypermnestra (a species of satyrine butterfly), which is found throughout wide areas of tropical and subtropical Asia, adds a twist to this evolutionary strategy: the females evolved two distinct forms, either orange or dark brown, imitating two separate poisonous model species, Danaus or Euploea. (2021-01-14)

Behavioral traits converge for humans and animals sharing an environment
Humans, mammals and birds that live in a particular environment share a common set of behavioral traits, according to a new study, which identifies a local convergence of foraging, reproductive and social behaviors across species. (2021-01-14)

Foraging humans, mammals and birds who live in the same place behave similarly
Foraging humans find food, reproduce, share parenting, and even organise their social groups in similar ways as surrounding mammal and bird species, depending on where they live in the world, new research has found. (2021-01-14)

Bacteria carried by mosquitos may protect them against pesticides
Mosquitoes are transmitters of several diseases and pesticides are used to control their numbers in many countries. New study finds Wolbachia - a bacteria commonly found in insects - appears to protect them against these pesticides. (2021-01-13)

Asian butterfly mimics other species to defend against predators
Many animal and insect species use Batesian mimicry -- mimicking a poisonous species -- as a defense against predators. The common palmfly Elymnias hypermnestra -- a species of satyrine butterfly that is found throughout wide areas of tropical and subtropical Asia -- adds a twist to this evolutionary strategy.

Penned release of green geckos has potential to help preserve threatened native species
In a paper just published in the New Zealand Journal of Ecology, the Department of Zoology researchers outlined how they translocated 19 barking geckos to Mana Island, using the method of penned release - enclosing them in a 100m² pen for three months so they get used to the site and hopefully establish a breeding population. (2021-01-13)

Artificial intelligence puts focus on the life of insects
Scientists are combining artificial intelligence and advanced computer technology with biological know how to identify insects with supernatural speed. This opens up new possibilities for describing unknown species and for tracking the life of insects across space and time (2021-01-12)

Study finds future too warm for baby sharks
A new study conducted at the New England Aquarium finds that as climate change causes the ocean to warm, baby sharks are born smaller, exhausted, undernourished, and into environments that are already difficult for them to survive in. (2021-01-12)

DNA in water used to uncover genes of invasive fish
In a proof-of-principle study, Cornell researchers describe a new technique in which they analyzed environmental DNA - or eDNA - from water samples in Cayuga Lake to gather nuanced information about the presence of these invasive fish. (2021-01-12)

Scientists discover bizarre new mode of snake locomotion
Researchers have discovered a new mode of snake locomotion that allows the brown tree snake to ascend much larger smooth cylinders than any previously known behavior. (2021-01-11)

This tree snake climbs with a lasso-like motion
Researchers reporting in Current Biology on January 11 have discovered that invasive brown tree snakes living on Guam can get around in a way that had never been seen before. The discovery of the snake's lasso-like locomotion for climbing their way up smooth vertical cylinders has important implications, both for understanding the snakes and for conservation practices aimed at protecting birds from them. (2021-01-11)

Researchers find nonnative species in Oahu play greater role in seed dispersal
Oahu's ecosystems have been so affected by species extinctions and invasions that most of the seeds dispersed on the island belong to nonnative plants, and most of them are dispersed by nonnative birds. (2021-01-11)

Research explains why crocodiles have changed so little since the age of the dinosaurs
New research by scientists at the University of Bristol explains how a 'stop-start' pattern of evolution, governed by environmental change, could explain why crocodiles have changed so little since the age of the dinosaurs. (2021-01-07)

Native biodiversity collapse in the Eastern Mediterranean
An international team led by Paolo G. Albano from the Department of Palaeontology at the University of Vienna quantified a dramatic biodiversity collapse of up to 95 per cent of native species in the Eastern Mediterranean. The study is published in the Proceedings of the Royal Society B: Biological Sciences. (2021-01-07)

Unusual sex chromosomes of platypus, emu and duck
Three studies uncovered the unusual sex chromosomes of platypus, emu and Peking duck. Platypus have five pairs of sex chromosomes forming an unusual chain shape, while the sex chromosomes of emu and duck are not as different between sexes as those of human. The studies were led or co-led by Qi Zhou's group at the University of Vienna and Zhejiang University of China and are published as research papers in the journals Nature, Genome Research and GigaScience.

Eurasian eagle owl diet reveals new records of threatened giant bush-crickets
Bird diets provide a real treasure for research into the distribution and conservation of their prey, conclude scientists after studying the Eurasian Eagle Owl in southeastern Bulgaria. In their paper, published in the open-access, peer-reviewed journal Travaux du Muséum National d'Histoire Naturelle ''Grigore Antipa'', they report the frequent presence of the threatened Big-Bellied Glandular Bush-Cricket, and conclude that studies on the Eurasian Eagle Owl could be used to identify biodiversity-rich areas in need of protection. (2021-01-05)

New bacterial culture methods could result in the discovery of new species
A new microbial study explored the bacterial diversity of the Tabernas Desert located in the south-eastern Spain. Using simple tweaks of the traditional bacterial culture methods, the researchers isolated more than 250 bacterial strains of which 80 could be possible new bacteria species. (2021-01-05)

New work provides insight into the relationship between complexity and diversity
Parts of the planet that are diverse biologically and culturally are even more diverse than you'd expect. A group of Santa Fe Institute collaborators developed a theory to show why richer environments are also more complex environments, where you tend to find more species and languages. (2021-01-05)

Risk of extinction cascades from freshwater mussels to a bitterling fish
Reproduction of native and invasive bitterling fishes and their hybridisation was studied in Japan. We collected mussels in which these bitterlings lay their eggs, kept them in aquaria, collected eggs/larvae ejected from mussels, and genotyped them. We found that hybrids occurred when local mussel density was low. The rapid decline of the host mussels and artificial introduction of an invasive congener interacted to cause the rapid decline of a native fish. (2021-01-04)

Pandas' popularity not protecting neighbors
Doubt is cast on the long-held hope that the conservation protections granted pandas and other adored threatened species extended to their wildlife neighbors, calling for broader conservation efforts. (2021-01-04)
