A model for the evolution of intelligence      (via sciencedaily.com)     Original source 

When certain species of wild birds and primates discover new ways of finding food in the wild, it can serve to measure their flexibility and intelligence. In the largest experimental study ever conducted on this topic, researchers have shown that foraging problems requiring overcoming obstacles, such as removing the lid off a container of food, are the only predictors of brain size and innovative behavior in the wild.

Study results show 25% of pregnant people are not getting enough omega-3 fatty acids from their diet or dietary supplements      (via sciencedaily.com)     Original source 

Results from a new US nationwide cohort study show that, despite strong recommendations in favor of consuming omega-3 fatty acids for optimal pregnancy outcomes and offspring health, 25% of participants reported rarely, or never eating fish during pregnancy, with fewer taking omega-3 supplements.

Slimming down a colossal fossil whale      (via sciencedaily.com)     Original source 

A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.

Small dietary changes can cut your carbon footprint by 25%      (via sciencedaily.com)     Original source 

New research provides compelling evidence that partially substituting animal with plant protein foods can increase life expectancy and decrease greenhouse gas emissions. Importantly, it also suggests that benefits depend on the type of animal protein being replaced. The study drew data from a national nutrition survey to analyze Canadians' dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, tofu, and fortified soy beverages, on a combination of nutrition, health, and climate outcomes.

Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature      (via sciencedaily.com)     Original source 

More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022. The GBF focuses on understanding why biodiversity is declining and what actions are needed to reverse this trend. However, according to researchers, implementing the plan is challenging because information about biodiversity changes is not evenly available everywhere, and is uncertain in many places.

The Golgi organelle's ribbon structure is not exclusive to vertebrates, contrary to previous consensus      (via sciencedaily.com)     Original source 

Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.

The veil varies more than the threat: Predator selection on variability in camouflage and warning signals      (via sciencedaily.com)     Original source 

Researchers leveraged open-access digital collections to validate an age-old hypothesis in evolutionary ecology. The classic hypothesis proposes that predators select for a great variety of camouflage and a limited variety of warning signals, but the idea has never been tested on natural prey.

Climate change shrinking fish      (via sciencedaily.com)     Original source 

Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study. Researchers analyzed the individual weight and overall biomass of 13 species of fish. In the 1980s and 2010s, the fish were lighter. They attributed the first period of weight loss to greater numbers of Japanese sardine, which increased competition with other species for food. During the 2010s, while the number of Japanese sardine and chub mackerel moderately increased, the effect of climate change warming the ocean appears to have resulted in more competition for food, as cooler, nutrient-dense water could not easily rise to the surface. These results have implications for fisheries and policymakers trying to manage ocean resources under future climate change scenarios.
