Absolutely. A single confabulated reference is enough for me to reject a paper as a reviewer or editor. This is only a problem if we let it be a problem.

This is the thing, if "academia" wanted to stop this, we could easily tomorrow. Over 3 incorrect references? Rejected and forbidden to submit next year. The purpose of a system is what it does!

Whoops, that Ocean sunfish (Mola mola) is not in the family Centrarchidae of freshwater sunfishes. Common names can cause confusion.

"Amazon molly has accumulated mutations much faster than it's parent species, but these mutations haven’t resulted in genetic decay. Instead, the fish has purged some harmful mutations thanks to a DNA repair process known as gene conversion, in which one version of a gene overwrites the other."

Male ligers and tigons are typically sterile, while female ligers and tigons are often, though not always, fertile. Haldane's Rule states that in hybrids, the sex with two different sex chromosomes (male XY in mammals) is more likely to be sterile. news.harvard.edu/gazette/stor....

The book documents all 632 species of freshwater fish in the region, including 597 native species, 467 of which are endemic and 35 non-native species. What is fascinating is that 41 % of the species have been described since the year 2000.

Detailed black-and-white illustration of the head and neck of a gigantic land tortoise labeled "Testudo microphyes." The tortoise's head is covered in large, distinct hexagonal and irregular scales, with textured, wrinkled skin along its thick neck. The eye is prominent and round, showing a glossy surface. The drawing emphasizes the rough, scaly texture and folds of the skin, highlighting the tortoise's massive size and ancient, rugged appearance. The image is part of an 1877 collection from the British Museum showcasing living and extinct giant land tortoises.

Huge News from the Western Amazon: it's the year 2025 and we are still describing entirely new, strikingly-distinctive large-bodied bird species! Behold Tinamus resonans sp. nov. the Slaty-masked Tinamou mapress.com/zt/article/v... #Ornithology @tetzoo.bsky.social 🪶
Photo montage of Tinamus resonans sp. nov., a new species of tinamou from the montane forests of the Serra do Divisor, western Amazonia, Brazil. The species is distinguished by a unique combination of plumage pattern, vocal repertoire, and ecological characteristics, including a conspicuous dark slate facial mask, vivid rufous-cinnamon underparts, and a uniform brownish-gray back. Its vocalizations are remarkable, consisting of long and powerful songs that echo strikingly across the steep montane slopes, producing a characteristic resonant effect. The species was documented exclusively at higher elevations within a transitional zone between submontane and stunted forests, where the understory is densely structured by root mats. A preliminary population estimate, based on field detections and spatial extrapolation, suggests approximately 2,106 individuals restricted to the Serra do Divisor massif. Although no immediate anthropogenic pressures were observed within its range, the species may be highly vulnerable to climate change and to proposed infrastructure projects that threaten the integrity of this federally protected region. The discovery of T. resonans highlights the biological uniqueness of the Serra do Divisor, reinforces its status as a center of montane endemism, and underscores the critical importance of maintaining its long-term conservation.

Then again, it does not always come down to microevolutionary causes. Species with extreme (large and small) body sizes have higher extinction risk, meaning ancestors tend to have intermediate body sizes. A similar pattern may exist for relative brain size too. www.pnas.org/doi/full/10....
