Open-air Processional Column Termites in Bukit Timah Nature Preserve, Singapore (2016)

June 17, 2017 at 5:05 pm / Natural history, NatureDocumentaries.org, Short Observations, Video, Wildlife Documentaries

Social insects are a major force in land habitats. A mature leaf-cutter ant colony can consume leaf material equal to a weight of a cow every day. Termites are another insect group (related to cockroaches) evolved independently to achieve sociality. Their effects on ecosystems in terms of material and nutrient cycling can rival those of ants. Higher termites (family Termitidae) feed on a wide variety of plant-based material, including decaying wood, leaf litter, humus, fungi, lichens, dung, and grasses. Non-wood-feeding […]

The Diatomist – Matthew Killip (2014)

June 17, 2017 at 12:00 am / Natural history, Video

Klaus Kemp, is a self-taught master of the Victorian art of diatom arrangement. After his first exposure to the intricate patterns of algae by the German microscopist J.D. Möller (1844 – 1907) he was completely hooked. Diatoms are single celled algae. They are the most common form of phytoplanktons and form the base of the aquatic food chains. They represent the earliest plant lineage long before land plants evolved at about 700 million years ago. Their cell walls are made […]

Seed Dispersal and Habitat Fragmentation | HHMI BioInteractive – Danny Schmidt (2017)

June 10, 2017 at 7:06 pm / Ecological Documentaries, Natural history, Video, Wildlife Documentaries

Forests are under intense pressure. In the tropical forests, between 50-90 % of the canopy trees depend on animals for seed dispersal. Even in temperate forests animals such as deer, moose, boar and even bears disperse seeds. Today due to hunting for bush meat many tropical forests are becoming depleted of their seed dispersers. Here in this HHMI documentary, the researchers Andres Link and Carolina Urbina Malo of Los Andes University in Colombia in Colombia track brown spider monkeys to […]

June 7, 2017 at 12:42 pm / Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

In the James Bond movie Spectre there’s a reference to the cuckoo bird in two scenes. The evil villain Spectre leers: “I see you! Cuckoo!” when he detects Bond in the classic evil assembly room scene. In the other scene towards the end of the movie Spectre reveals why he considers Bond as a cuckoo. In order to understand the reference we must know the biology of the Common cuckoo bird (Cuculus canorus). The European common cuckoo is a well […]

Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades – HHMI (2016)

May 29, 2017 at 5:39 pm / Ecological Documentaries, Natural history, Video, Wildlife Documentaries

On a field trip with students to the Pacific Coast, ecologist Robert Paine discovered a thriving community of aquatic organisms at Mukkaw Bay, at the tip of the Olympic Peninsula. The tide pools were full of green anemones, purple sea urchins, pink seaweed, bright red Pacific blood starfish, as well as sponges, limpets, and chitons. At the low tide rocky surfaces exposed bands of small acorn barnacles, and large, stalked goose barnacles, beds of black California mussels, and some very […]

A Wolf’s Place – Annie White (2013)

May 29, 2017 at 5:26 pm / Ecological Documentaries, Natural history, Video, Wildlife Documentaries

Ecological theory predicts that by keeping herbivore populations under check predators can indirectly enhance growth of vegetation and can even alter local climate. The influential ecologist Robert Paine has demonstrated this phenomenon of keystone species on predatory starfishes and sea otters maintaining species diversity in coastal rocky communities in Washington. Directed and produced by Annie White, “A Wolf’s Place” tells the story of wolf reintroduction to Yellowstone national park in 1995. Wolves became locally extinct in much of the United […]

Otters vs. Climate Change – KQED/QUEST (2014)

May 29, 2017 at 4:35 pm / Ecological Documentaries, Natural history, Video

Presence and absence of keystone species in a biological community have significant effects. To cite a few examples: Tropical fig trees form abundant food resources for many animals in times of scarcity. Bluechub fish in Eastern North American rivers construct rock nests which form a critical spawning area for many other fish in the same habitat. Beaver activity slows down hydrology and enhances water retention capacity of the ecosystems. Increased water table invigorates vegetation. At the same time reduced sun […]

Leave It to Beavers – PBS (2014)

May 22, 2017 at 1:14 pm / Ecological Documentaries, Natural history, PBS Nature, Video, Wildlife Documentaries

There are two species of beavers in the temperate zones of the world. North American (Castor canadensis) and Eurasian (Castor fiber) beavers were almost exterminated to extinction. These rodents are the largest after the tropical capybara that lives in wetlands of the South American tropics. Now bouncing back from extinction beaver populations are recovering under protection. Beavers are being recognized as keystone species by ecologists and conservation biologists. As habitat constructors and brilliant hydro-engineers, beavers can recharge water tables and […]

Genesis: Final Point – Fernando Gonzalez-I. Sitges (2000)

May 16, 2017 at 7:23 am / Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

Galapagos archipelago occupies a special place in our quest to understand nature. It sits right on the junction of the Pacific ocean current where warm and cold water shifts. The nutrient levels reaching the islands by cold Humboldt current show a drastic decline when warm surface waters engulf the archipelago. The Galapagos lies at the southeast trade winds. When the current shifts the rainfall pattern changes drastically. The
