Ranking locations for lion conservation in southern Africa -- a new approach

An international team of scientists has developed a new strategy to rank locations for lion conservation activities, based on GPS collar data revealing lions' movements. Read more

A new twist on how parasites invade host cells

Researchers have decoded the mechanisms used by the parasite Toxoplasma gondii to enter the cells of a host. Using high-resolution, high-speed imaging, they identified a unique process by which the parasite closes the 'entry door' it creates in order to enter and inhabit a host cell. Read more

Territory holders and floaters: Two spatial tactics of male cheetahs

Scientists have analyzed the spatial behavior of cheetahs. They showed that male cheetahs operate two space use tactics which are associated with different life-history stages. Read more

Map of Javan leopard distribution provides guidance for conservation efforts

The first robust estimate of the distribution of the Javan leopard offers reliable information on where conservation efforts must be prioritized to safeguard the Indonesian island's last remaining large carnivore. Read more

Lion conservation research can be bolstered by input from a wide-range of professionals

To tackle the sharp decline in lion numbers, conservation research should consider wild prey, livestock and the environment, not just human-lion interaction, a new review suggests. Read more

Dogs prefer to eat fat, and cats surprisingly tend toward carbs

Dogs gravitate toward high-fat food, but cats pounce on carbohydrates with even greater enthusiasm, according to research into the dietary habits of America's two most popular pets. Read more

Secret life of an enigmatic Antarctic apex predator

Scientists have, for the first time, tracked the lives of leopard seals as they migrate around Antarctica. The team followed these formidable predators as they move from the frozen Antarctic sea-ice to the more northerly sub-Antarctic islands where they prey on penguins, seals and krill. Read more

Quantum effects observed in photosynthesis

Molecules that are involved in photosynthesis exhibit the same quantum effects as non-living matter, concludes an international team of scientists. This is the first time that quantum mechanical behavior was proven to exist in biological systems that are involved in photosynthesis. The interpretatio Read more

New virus identified in cat

Researchers have found a previously undiscovered hepadnavirus in an immunocompromised cat, and subsequently in banked samples. Read more

Leopard meals: Females go for diversity

Leopards, top predators of the African savannah, are known to feed on a variety of prey species. It has been largely unknown, however, whether they specialize in certain prey animals and which factors might influence prey preferences. Scientists investigated these questions by studying the diet of l Read more

How cheetahs outsmart lions and hyenas

Cheetahs in the Serengeti National Park adopt different strategies while eating to deal with threats from top predators such as lions or hyenas. A new study shows that male cheetahs and single females eat their prey as quickly as possible. Mothers with cubs, on the other hand, watch out for possible Read more

Rats, cats, and people trade-off as main course for mosquitoes in Baltimore, Md.

Understanding how neighborhood dynamics regulate mosquito bites is key to managing diseases like West Nile virus and Zika virus. Today in Parasites & Vectors, researchers report that in Baltimore, Md., socioeconomic differences between neighborhoods influence bite risk, with rats being a primary Read more

Jaguars and well-managed logging concessions can coexist, say conservationists

Logging activities in biodiverse forests can have a huge negative impact on wildlife, particularly large species such as big cats, but a new study proves that the Western Hemisphere's largest cat species -- the jaguar (Panthera onca) -- can do well in logging concessions that are properly manag Read more

Research suggests low density of snow leopards in Nepal`s Conservation Area

The snow leopard is a mammal species of the cat family found at high altitudes in Nepal and other countries around the Himalayan range. However, it has been included in the vulnerable category of IUCN Red list of threatened species in recent years for various reasons. Read more

Animal nutrition: Excess phosphorus damages the kidney

A new study carried out by veterinarians shows that high phosphorus intake, comparable to the average level provided by prepared cat food, can be deleterious to kidney function in healthy cats. Read more

The problem of jaguars and space in western Paraguay

A recent study shows how researchers used GPS technology and new analytical techniques to produce the first rigorous estimates of jaguar spatial needs and movements in the Gran Chaco and Pantanal ecosystems of Paraguay. Read more

First evidence of live-traded dogs for Maya ceremonies

Earliest evidence that Mayas raised and traded dogs and other animals -- probably for ceremonies -- from Ceibal, Guatemala. Read more
