Field Frame Friday: Hygienic bees

This photo shows a circular section of comb that bees have (mostly) cleared of larvae that were made to simulate diseased brood. Bees will remove the capping on these “diseased” larvae and take them out of the hive before the pathogen can reach it’s infectious stage, thus keeping the colony healthy! We usually hope for…

Field Frame Friday: Don’t get comfy…

White terns (Gygis alba) don’t build nests for their eggs! They usually find a fork in a branch and stay on their egg during incubation (Miles 1986). The chicks are born with adapted feet to cling to the branch while the mom goes searching for fish dinners. [Photo by Nick Chudeau; Caption by Karli Chudeau]…

Field Frame: World Lemur Festival

  Happy world lemur festival! The Indri is the largest of the living lemurs (although there used to be lemurs as big as gorillas!). Adults live in pairs and sing duets each morning, which can serve to improve group cohesion (Giacoma et al., 2010) and defend their forest territory (Pollack, 1986). Their name in Malagasy, Babakoto,…

Field Frame Friday: Living that island life

Native to Aldabra Atoll in the Seychelles, Aldabran Giant Tortoises (Aldabrachelys gigantea) don’t have to deal with predation, and with an abundance of tropical food, warm weather, and environmental protection, they spend their days grazing vegetation in the morning, and snoozing on beaches in the afternoon, taking dips into shallow pools of water to regulate their temperature. These tortoises are one way that local land plants disperse their seeds (Hnatiuk, 1978).

Field Frame Friday: Parasitism in the rainforest

While we often don’t consider them, parasites are a common occurrence in the natural world. Here, it might just look like unidentified snail from Kahuzi-Biéga National Park, D.R. Congo, but if you look closely, you’ll see a minuscule wasp on the snail (circled in frame). It is unclear if this is a parasitoid wasp laying…

Field Frame Friday: Resident sharks

The great hammerhead (Sphyrna mokarran) is a seasonal resident of Bimini, Bahamas during the winter months. This is the largest species of hammerhead shark, reaching lengths of up to 20 feet. They are easily identified by their characteristic hammer-shaped heads, or cephalofoils, which may help them search for prey found under the sand (Kajiura, 2001)….

Field Frame Friday: Forest monkeys

Commonly known as the red-tailed monkey, Schmidt’s guenon, or the black-cheeked, white-nosed monkey, this primate species (Cercopithecus ascanius) ranges across much of Central Africa. This male, named Kinky for the bend in the end of his tail, was photographed in the Issa Valley, part of the Ugalla Region, Tanzania. He was one of a couple…

Field Frame Friday: Silent shadow

Mossel Bay, South Africa is a known hotspot for great white sharks (Carcharodon carcharias). More mature individuals gather in this area during the winter months in this region, likely drawn by the abundance of pinnipeds (seals and sea lions) that are found on small rocky islands, as seen in the background here. This photograph was taken…
