Updates from NASA’s Curiosity Rover [Mars Science Laboratory]

April 15, 2023 at 11:38 pm / Cosmological, Global Patterns, NatureDocumentaries.org, Video

Geological evolution of the Earth and Mars have started from very similar origins but yet the two planets have followed quite different trajectories. Geology of our planet has shaped the evolution of life (and vice versa). Understanding Mars will also help understand our own planet. For this reason, Nature Documentaries will be paying attention to this ambitious Mars rover project. Jet Propulsion Laboratory has been holding regular detailed update sessions. You can follow some of these updates below starting from […]

The Passionate Wait

October 6, 2022 at 12:23 pm / Ecological Documentaries, Evolution, Natural history, NatureDocumentaries.org, Video, Wildlife Documentaries

This short documentary highlights events before the opening of the passionflower (Passiflora incarnata) flowers. Drought conditions during the summer of 2011 increased the activity of many insects and spiders around the extrafloral nectaries of the plant. The water budget of the plants is strongest early in the morning. Flowers do not open until the middle of the day. At first, passion flower is generous especially to the ants in the morning providing ample volume of nectar. Ants provide protection to […]

Acid Attack

September 22, 2022 at 10:22 pm / Ecological Documentaries, Evolution, Natural history, NatureDocumentaries.org, Short Observations, Video, Wildlife Documentaries

Nectar is an effective concoction for establishment and maintenance of plant-animal interactions. Using nectar, plants can build a community of allies for defense and even manipulate the behavior of pollinators. We are accustomed to nectaries found in flowers. Plants however, have evolved nectaries in other locations in their above-ground parts including the base of the flowers and petioles. These are called extrafloral nectaries. The sugary reward coming from the extrafloral nectaries invites ants to defend them. Here we can see […]

Prominent Features of Leaf-footed Stinkbugs

August 5, 2022 at 8:18 pm / Ecological Documentaries, Evolution, Natural history, Video

The leaf-footed stinkbugs have quite a few eye-catching body features including highly specialized mouthparts, offensive and defensive adaptations. This is an order of insects on which evolutionary pressures are visibly active shaping their morphologies. The evolutionary trade-offs underpinning these structures are an active research subject by biologists. Here, three characteristic body parts in leaf-footed stink bugs are highlighted: The labium, the pronotum and the components of the hind leg (femur and tibia). Entomologically, the femur and the tibia are the […]

Stalking Seal on the Spring Ice – Quentin Brown & Asen Balıkçı (1968)

June 7, 2022 at 7:58 pm / Ecological Documentaries, Human Nature, Video

Diverse ways of sustenance on the frontiers of the world fascinate us about Human adaptability and effective resource use. Stalking for seals on sea ice is one of the best documented hunting technique which employs quite exceptional behavioral deception tactics. The hunter uses a cognitive ability called “theory of mind” to overcome behavioral tripwires for prey to escape. The hunter projects the world from the view point of the prey and adjusts own behavior to a successful intercept. The hunter […]

Newtok | The Water is Rising / Patagonia Films (2022)

June 7, 2022 at 11:27 am / Global Patterns, Human Nature, Video

Human induced climate change is creating fast coastal landscape changes and during that process turn many indigenous communities into climate refugees. Co-directed by Michael Kirby Smith and Andrew Burton, Newtok | The Water is Rising highlights demise of a population. Rising sea levels threaten Newtok, Alaska. The Arctic permafrost is melting at an increasing rate. Due to Polar Amplification the speed of climatic change in the Arctic is rather fast. To keep their culture and community intact, the Yup’ik residents […]

May 1, 2022 at 10:02 am / Evolution, Human Nature, Molecular Nature, Video

Domestication of plants and animals is a key transformation in recent Human evolutionary history leading to sedentary farming societies. Domestication of Maize particularly followed a different trajectory from the agricultural crops of the old world. This HHMI documentary tells how the ancestral wild grass called Teosinte was domesticated to evolve into Maize. In the old world, most domesticated grasses had a surprisingly similar “first step” that paved the way towards agriculture. In old world grasses including rice, wheat, barley and […]

A Frequently Yawning Rough Green Snake (Opheodrys aestivus)

March 4, 2022 at 8:25 am / Natural history, NatureDocumentaries.org, Short Observations, Video, Wildlife Documentaries

This beautifully bright green snake is a master of disguise. Although they are fairly long (can be up to 81 cm) it is almost impossible to notice them unless you have been curiously scanning the vegetation with a purpose. The Rough Green Snake (Opheodrys aestivus) is behaviorally very docile. It must be a slow day for this particular individual since s/he was frequently yawning. The observation was recorded on 9th of September 2012 at the Georgia State Botanical Garden in […]
