Large herbivores keep invasive plants at bay      (via sciencedaily.com) 

Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.

Evolutionary imbalance explains global plant invasions      (via sciencedaily.com)     Original source 

Plant species from certain geographic regions are more successful in spreading outside their native ranges than others -- but why? Ecologists provide answers by exploring how the ecological and evolutionary histories of plants can influence their relationships with humans and their success as invaders.

Algae provide clues about 600 million years of plant evolution      (via sciencedaily.com)     Original source 

Researchers generated large scale gene expression data to investigate the molecular networks that operate in one of the closest algal relatives of land plants, a humble single-celled alga called Mesotaenium endlicherianum.

Want to fight climate change? Don't poach gorillas (or elephants, hornbills, toucans, etc.)      (via sciencedaily.com)     Original source 

A new article found that overhunting of gorillas, elephants, and other large fruit-eating seed-dispersers make tropical forests less able to store or sequester carbon.

Male crested macaques more likely to respond to offspring screams recruiting support      (via sciencedaily.com)     Original source 

When infants are involved in agonistic conflicts, male crested macaques (Macaca nigra) are more likely to respond to screams from their own offspring. This is the conclusion of a recent study led by behavioral ecologists. The researchers studied the behavior of crested macaques in the Tangkoko Nature Reserve on Sulawesi, Indonesia, over a 24-month period (2008 to 2010).

Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution      (via sciencedaily.com)     Original source 

Scientists use cutting edge scanning technology to reconstruct 'fossil monster' that lived half a billion years ago. The creature's soft anatomy was well-preserved, allowing it to be imaged almost completely: It fills a gap in our understanding of the evolution of arthropods such as insects and crustaceans.

Wastewater pipe dig reveals 'fossil treasure trove'      (via sciencedaily.com)     Original source 

A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.

Fungi-eating plants and flies team up for reproduction      (via sciencedaily.com)     Original source 

Fungi-eating orchids were found for the first time to offer their flowers to fungi-eating fruit flies in exchange for pollination, which is the first evidence for nursery pollination in orchids. This unique new plant-animal relationship hints at an evolutionary transition towards mutualistic symbiosis.

Loss of Antarctic sea ice causes catastrophic breeding failure for emperor penguins      (via sciencedaily.com)     Original source 

Emperor penguin colonies experienced unprecedented breeding failure in a region of Antarctica where there was total sea ice loss in 2022. The discovery supports predictions that over 90% of emperor penguin colonies will be quasi-extinct by the end of the century, based on current global warming trends.
