  • Brown Wood Rail singing in the Chocó forests of Ecuador – Luke Browne (2013)

    Brown Wood Rail singing in the Chocó forests of Ecuador – Luke Browne (2013)

    The Brown Wood Rail (Aramides wolfi) is a poorly known bird from western Colombia, Ecuador, and Peru. Because of extensive habitat loss,it’s considered vulnerable to extinction with less than 4,000 individuals remaining. Here, we recorded an individual singing in front of a motion-activated camera trap at Bilsa Biological Station, one of the largest remaining pieces of Chocó forest in western Ecuador. Bilsa is located within Machine-Chindul Ecological Reserve, Esmeraldas province, Ecuador. The Karubian lab at Tulane university has described the […]

  • Invasive Lionfish of the Tropical Atlantic – Marine Ecology Expeditions – Lorenzo Mittiga (2012)

    Invasive Lionfish of the Tropical Atlantic – Marine Ecology Expeditions – Lorenzo Mittiga (2012)

    Lionfish are popular aquarium fish native to the Indo-Pacific region. The lionfish invasion in the western Atlantic began in the mid 1980s off the southern coast of Florida, USA. From Florida, lionfish have spread in all possible directions. By 2000, individuals had been sighted off the coast of North Carolina and Bermuda. First lionfish were reported from the Bahamas in 2004, where they quickly dispersed throughout the archipelago by 2007. The range of lionfish has increased further southward. Lionfish now […]

  • Pitcher Plants of Palawan – Stewart McPherson (2010)

    Pitcher Plants of Palawan – Stewart McPherson (2010)

    The naturalist and explorer Stewart McPherson sets out to discover new species of pitcher plants on the Island of Palawan in the Philippines. Carnivorous plants have the most impressive adaptations that help them survive comfortably in low-nutrient environments. Most plants absorb nutrients through their root but carnivorous plants trap and digest various invertebrates to get nutrients. Even small frogs and mammals can become prey. McPherson previously discovered 5 new species of pitcher plants and photographed one that has trapped a […]

  • Female Frog (Leptodactylus insularum) Leading Her School – Kristiina Hurme (2006)

    Female Frog (Leptodactylus insularum) Leading Her School – Kristiina Hurme (2006)

    Leptodactylus insularum is a tropical frog occuring in Colombia, Costa Rica, Panama, Trinidad and Tobago, Venezuela. In this video, a female Leptodactylus insularum pumps her abdomen in the water, and tries to lead the school towards a different area in the swamp. Females attend schools for varying amounts of time, and this is a fairly young school, which may explain why they are slow to follow her. Or perhaps they’re feeding on a great patch and don’t want to leave! […]

  • 21st Century Temperature and Precipitation Scenarios from IPCC

    21st Century Temperature and Precipitation Scenarios from IPCC

    Climate models used by the Intergovernmental Panel on Climate Change (IPCC) estimate global temperature and precipitation patterns will change throughout the 21st century because of rising greenhouse gas concentrations. The visualization above is based on one of the four scenarios called Representative Concentration Pathways (RCPs) in which carbon dioxide concentrations reach 670 parts per million (ppm) by 2100, up from around 400 ppm today. The carbon dioxide concentrations in the year 2100 for each of the four RCPs are: RCP […]

  • The Queen of Trees PBS (2006)

    The Queen of Trees PBS (2006)

    Queen of Trees is now viewable on the official YouTube Channel of Victoria Stone and Mark Deeble. Veteran wildlife filmmakers Victoria Stone and Mark Deeble once again put out a marvelous work by compiling observations on a community centered around a sycamore fig tree. The success of the documentary comes from their long-term observations in a particular filming spot in Kenya where they camped on location for more than two years. A thorough understanding of the landscape with it’s inhabitants […]

  • Metamorphosis – Tale of a Wetland (Bryan Maltais 2012)

    Metamorphosis – Tale of a Wetland (Bryan Maltais 2012)

    Nature reveals its ability to heal when amphibians, reptiles, birds and plants repopulate a recently abandoned rock quarry to create a flourishing wetland in Fort Collins, Colorado. However, the scarred earth of this healing quarry causes salamanders to undergo a rare and peculiar shift in their morphology. Time-lapse sequences show seasonal changes of the wetland over one year accompanied by underwater footage of amphibians breeding and undergoing metamorphosis. Everybody is familiar with the metamorphosis of butterflies and moths. The following […]

  • Sponge Bob or Sponge “Poop”

    Sponge Bob or Sponge “Poop”

    It is ironic that biologically diverse habitats are usually rather poor in nutrients. Coral reefs are one of them. Crystal clear waters of the tropical seas is a “clear” indication of nutrient poor environment. Because nutrients in the water column are scarce microscopic plants and animals (planktons) that form the basis of food webs cannot maintain high numbers and the water column remains clear. Dissolved organic carbon is a nutrient that is inedible for most organisms living in a reef. […]

  • Nesting Chestnut Mandibled Toucan (Ramphastos swainsonii)

    Nesting Chestnut Mandibled Toucan (Ramphastos swainsonii)

    Filmed and edited by by Jean and Phil Slosberg in 2010 the captured footage reflects a slice of natural history of chestnut-mandibled toucans. Slosbergs were able to record the nest preparation, parental care and nest maintenance phases from their home in Costa Rica. They note that after a successful breeding season the pair tried to nest in the same tree again in 2011 but were not successful because meliponid stingless bees have taken over the cavity. They attempted to clean […]

  • The Passionate Wait

    The Passionate Wait

    In the second part of the passion flower series events before the opening of the flowers are outlined. Drought conditions in summer of 2011 made extrafloral nectaries of the plant a very busy place. 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 to the ants in the morning providing ample volume of nectar. On the other hand, pollinators remain hungry. […]

  • Ants – Nature’s Secret Power (2006)

    Ants – Nature’s Secret Power (2006)

    Ants, bees and wasps make up only 3 percent of animal diversity yet they may constitute up to 50 percent of the total animal biomass in land habitats. Bert Hölldobler is a leading entomologist (scientist who studies insects). He collaborated with ant biologist E.O. Wilson and developed the field of Sociobiology. The documentary does an excellent job introducing us observations coming from both natural and laboratory setting. First observation comes from the European red wood ants (Formica polyctena). These ants […]

  • Nesting Nightjar in Camouflage

    Nesting Nightjar in Camouflage

    This is an excellent footage capturing the behavior of a ground nesting nightjar. These birds are night-flying aerial insectivores active during dusk and dawn. It is almost impossible to see them during the day because of their camouflage. Nightjars are also known as goatsuckers which has no biological basis. If an intruder comes dangerously close to the nest, adults perform a well-known “broken wing” display. It is an excellent visual distraction. The bird will easily disappear soon after the intruder is at a […]

  • Daytime Hunting of Barred Owl (Strix varia)

    Daytime Hunting of Barred Owl (Strix varia)

    On April 16th 2011, a barred owl glided over my head while I was filming something else along the Orange Trail of the State Botanical Garden of Georgia in Athens, GA. Hunting during daytime indicates that this individual has extra mouths to feed. You can hear the altruistic alarm calls of other nervous birds and rodents. The high pitched alarm call (of a chipmunk?) is particularly audible immediately before each move of the owl. I deliberately kept the scenes long […]

  • Acid Attack

    Acid Attack

    Wildflowers can build a community of allies for defence. Ants defend extrafloral nectaries (nectar produced in organs other than flowers) of a passion flower vine against herbivores. This is an example of plant-animal interaction evolved to solve at least three biological problems. [1] Extrafloral nectaries seen in this video resemble butterfly eggs.  Butterflies avoid laying their eggs on host plants if they see other eggs. This is particularly true for two species of butterflies Gulf fritillary (Agraulis vanillae) and Variegated […]
