Monkey droppings complement field observations, researchers report

Researchers used high-throughput sequencing to analyze fecal DNA of saddleback tamarins, identifying 20 families and genera of invertebrates consumed. This study complements behavioral observations and ecological sampling, providing insight into the monkeys' foraging strategies.

Fishing amplifies forage fish collapses

A new study reveals that fishing likely contributes to population collapses in forage fish, including herring, anchovies, and sardines. The research suggests that suspension of fishing when populations fall below half their average can prevent 64% of collapses with minimal impact on fisheries.

Bats obey 'traffic rules' when trawling for food

Researchers found that bats follow a set of 'traffic rules' when foraging, including chasing, turning, and avoiding collisions. The bats swap leadership roles during these interactions by copying the previous individual's flight direction up to 500 milliseconds earlier.

Flower-enriched farms boost bee populations

A two-year study found that flower strips on farms in the UK increased common bumblebee populations by significantly boosting their numbers and nesting density. The research suggests that targeted agri-environment schemes can boost bee populations, particularly for common species, but may not benefit rarer species as much.

Home is a safe haven for female deer

Researchers tracked female black-tailed deer's movements and found their home ranges were very small, averaging 0.74 square kilometers, with core areas of just 0.08 km². This site familiarity helps them survive by knowing the best foraging spots and avoiding risky territories.

Birds conform to local 'traditions'

Researchers found that great tits learn new foraging techniques by observing others in their social network, adopting the dominant behavior and creating a stable tradition. Even when birds discover multiple methods, they tend to conform to the majority behavior, passing it down to the next generation.

Bats change strategy when food is scarce

Researchers found desert long-eared bats changed their diet from mostly scorpions on the ground to catching flying insects when prey was scarce. The change involved altered call and flight behavior, indicating potential flexibility in echolocation.

Little penguins forage together

Researchers found that 70% of little penguins' foraging tracks were associated with other penguins and 40% exhibited synchronized diving. These behaviors suggest group foraging and synchronization of underwater movements in little penguins.

Seals forage at offshore wind farms

Researchers tracked seals' movements using GPS and found some individuals repeatedly visiting offshore wind farms, where they foraged on turbines and pipelines. This behavior suggests that man-made structures serve as attractive hunting grounds, potentially impacting seal populations and prey availability.

Big brown bat males call 'dibs' on food

Researchers discovered that male big brown bats use uniquely distinctive calls to signal they want a meal, while females primarily forage near family members. These social calls were previously unknown and have been found in over 96% of recorded instances.

Waterbirds' hunt aided by specialized tail

Researchers found that waterbirds using different foraging strategies have evolved distinct tail shapes. Underwater foragers, such as cormorants and penguins, developed elongated tails with specialized vertebrae structures, while aerial birds had shorter, deflected tails.

Desire to reproduce drives active nightlife of birds

A study found that yellow-breasted chat males visit multiple territories at night to search for partners during their fertile period, increasing reproductive success. The researchers used radio transmitters and triangulation software to track the birds' movements, revealing a previously unknown behavior in diurnal species.

Turtles watch for, snack on gelatinous prey while swimming

Researchers found that loggerhead turtles rely on sight to identify and move towards gelatinous, floating prey like jellyfish and other organisms. They can snack on these low-energy foods approximately twice every hour, suggesting they may rely on such prey for energy more than previously thought.

Study provides first-time analysis of 3 distinct contributions of forage fish worldwide

A recent study led by the Institute for Ocean Conservation Science provides a first-time analysis of the value of forage fish to both commercial fisheries and marine ecosystems. The research found that forage fish contribute significantly to global fisheries, with a total estimated value of $16.9 billion annually, representing 20% of g...

Southern elephant seals likely detect prey bioluminescence for foraging

Research in southern Indian Ocean found increased bioluminescence correlates with higher foraging intensity in deep-sea predators, indicating that bioluminescence likely provides seals with valuable indications of prey occurrence. The study monitored diving behavior and light detector data from four female southern elephant seals.

Searching for tumors or handguns can be like looking for food

A laboratory study conducted by Duke University psychologists found that the brains of humans, including radiologists and baggage screeners, evolved to solve foraging problems in similar ways. The researchers discovered that people with fewer targets to find gave up on a given screen sooner compared to those with more targets.

Movement patterns of endangered turtle vary from Pacific to Atlantic

Critically endangered leatherback turtles show distinct travel modes in the North Atlantic and Eastern Pacific, with varying speeds associated with foraging and transit. The study suggests that Pacific turtles struggle to achieve high foraging success, hindering their population recovery compared to Atlantic turtles.
