A new global atlas reveals that up to 1.9 million km2 of the world's coastal waters are affected by artificial light at night, with significant impacts on marine organisms. The study uses a novel metric to determine the depth of light penetration and highlights the need for further research into the effects of ALAN pollution.
A new study found that human-caused bird extinctions lead to the loss of ecological roles, including pollination and seed dispersal. Introduced alien species do not fill these gaps, highlighting the disproportionate impact of human actions on biodiversity.
A new study by researchers at the University of Copenhagen found that the greatest increase in marine biodiversity on Earth occurred due to changes in climate cycles, rather than an asteroid explosion. Fossil analysis revealed a shift towards colder climates around 469 million years ago, leading to the blooming of marine life.
Research by Washington University in St. Louis explores the collision of island and mainland adaptive radiations in neotropical anoles, finding that island species can diversify greatly on the mainland. Contrary to traditional thinking, islands are not evolutionary dead ends but rather cauldrons of innovation and diversification.
A study found that 95% of fungal species on Earth remain undescribed, leading to inconsistent regulations and potential health risks. The researchers tested 16 food products labeled as containing 'wild mushrooms' and discovered most consisted of cultivated species, including poisonous varieties.
A new study reveals that just 42% of nations have expanded their scientific understanding of bird species distributions in the last decade. The researchers developed two new metrics to assess biodiversity data coverage and effectiveness, finding that regions like Asia and South America are closing knowledge gaps.
Researchers develop Composite Urban Quietness Index to measure sound diversity of quietness, aiming to provide a new understanding of comfortable quiet. The study reveals that high-intensity sound and silent acoustic environments can cause stress, highlighting the need for quantifiable characteristics of quietness.
The researchers proposed five strategies to address colonial legacies in ecology: decolonizing the mind, understanding history, increasing access to information, recognizing diverse expertise, and establishing inclusive teams. These strategies aim to challenge biases and promote a more ethical approach to ecological research.
A new study led by Swansea University and the University of Bristol has revealed the size of Megalodon, including its massive fins. The shark's estimated body length is 16 meters, with a head diameter of 4.65 meters.
The study reveals that Asgard archaea, particularly the newly identified phylum Gerdarchaeota, are involved in degrading various substrates such as amino acids and ethanol. They also participate in aerobic respiration, converting substrates into acetyl-CoA.
A study found that increasing crop diversity in agricultural landscapes reduces aphid populations and decreases the need for pesticides. This is because natural enemies of aphids, such as ladybirds and spiders, have better living conditions in diverse landscapes.
The Ecological Society of America (ESA) is launching efforts to train ecologists in effective public engagement. The annual meeting will feature workshops, sessions, and a social event to promote knowledge sharing and networking among scientists who prioritize public engagement.
A University of Liverpool study found that ant colour and size are strongly influenced by their environment, with larger bodied ectotherms with dark colouration thriving in cold places. The study also revealed that ants adapt to changing temperatures by shifting from darker to lighter colours and smaller body sizes.
Researchers at University of Groningen find self-replicating molecules that diversify into distinct sets, sparking debate on life's molecular roots. The study reveals a process similar to biological speciation, but occurring at the molecular level.
In a study of Bahamas mosquitofish, female genitalia evolve to show 'no means no' to predators and interbreeding males. Females in areas with high predation risk have smaller genital openings, while those without predation risk have larger, more oval-shaped openings.
A study from University of California, Davis, found that forest disturbances like wildfire and thinning are replacing understory plants with those from more southern areas, such as Mexico and Southern California. This shift is driven by climate change, leading to a potential increase in forest diversity.
