In Darwin's Footsteps: Witnessing the Origin of a New Species in the Galapagos
Pulitzer-prize-winning author Jonathan Weiner of Columbia University will tell a story of discovery. By going back to the Galapagos year after year, scientists in Darwin’s islands have now witnessed an event that Darwin himself did not think could be seen at all. Darwin wrote that the origin of a new species would require “the lapse of ages.” But a small team of biologists has been observing the evolution of Darwin’s finches on a desert island in the center of the Galapagos archipelago for more than forty years. Their study shows that evolution can be surprisingly rapid and turbulent. The work throws light on many aspects of the science of life--including the science of the brain. Weiner is the author of The Beak of the Finch, and five other books. His writing has received many honors, including the National Book Critics Circle Award, the Los Angeles Times Book Award, and a Guggenheim Fellowship. He is the Maxwell M. Geffen Professor of Medical and Scientific Journalism at Columbia University’s Graduate School of Journalism. This talk is part of the Stavros Niarchos Foundation Brain Insight Lecture series, offered free to the public to enhance understanding of the biology of the mind and the complexity of human behavior. The lectures are hosted by The Mortimer B. Zuckerman Mind Brain Behavior Institute at Columbia University and supported by the Stavros Niarchos Foundation.

Ecology, Evolution, and Species Diversification in Hawaiian Islands
Rosemary Gillespie, Professor and Schlinger Chair in Systematic Entomology, University of California, Berkeley Oceanic "hotspot" archipelagoes—such as Hawaii —in which volcanoes have been formed sequentially over extended periods of time, allow us to study a single island as a “snapshot” in time. In this way we can look at how communities of organisms come together and how ecological interactions evolve. Rosemary Gillespie will discuss her research on the evolution and ecology of spiders in the Hawaiian archipelago and why understanding the abundance and interactions of species within ecosystems can provide insights into the forces that shape biodiversity. She will also highlight how this work is relevant to managing invasive species and restoring ecosystems. Series supported by a generous gift from Drs. Herman and Joan Suit March 22, 2016
From Supercontinents to Islands - Evolution in Motion
Gonzalo Giribet, Professor of Organismic and Evolutionary Biology, Department of Organismic and Evolutionary Biology, Curator of Invertebrate Zoology, and Alexander Agassiz Professor of Zoology, Museum of Comparative Zoology, Harvard University The biological diversity found on an island is closely related to the history of its formation. Islands such as New Zealand, Tasmania, New Caledonia, and Madagascar formed when the supercontinents Pangea and Gondwana broke apart millions of years ago. These islands inherited organisms from their continents of origin, but in the process of becoming isolated, the organisms diversified in ways—and at rates—that were unique. Gonzalo Giribet will discuss the evolutionary processes at play on these continental islands. Series supported by a generous gift from Drs. Herman and Joan Suit April 28, 2016
Underwater World of Taka Bonerate National Park [Gopro]
FOR THE BEST EXPERIENCE, USE YOUR HEADPHONE. -------------------------------------------------------------- Taka Bone Rate National Park is a marine park which includes the Takabonerate atoll islands, located in the Flores Sea, south of Sulawesi island of Indonesia. The plan was to create a video trip for the whole trip, that's include the long journey from Jakarta - Makassar - Selayar and finally Taka Bonerate. I have the footage, but later I realize I have so much Underwater footage from this trip (and I love it). So why not? All the plan change. It's all about Underwater World of Taka Bonerate. -------------------------------------------------------------- All the footage was Taken with Gopro Hero 4 Silver, Polarpro Switchblade v2.0 Filter, DIY Tray and Arm, 2xScubalamp PV40, Footage by Me and My Friend, Monica. Music by Relaxdaily Editing, Color Correction and Grading in Adobe Premiere and Adobe After Effect. -------------------------------------------------------------- All the questions about setup, setting, location, editing, etc. goes here at the comment section. If you like my work, don't forget to Like, Comment and Subscribe! And don't forget to share the video, let's spread the Beauty of Indonesia!!!

Community ecology: History and theory
In this first of three lectures on community ecology, Dr. Dan Simberloff presents an overview of of community ecology, and highlights some of the foundational theorists in the field. He offers a definition of the field, which focuses on understanding how many species live in a geographically defined community, and why particular species do or do not coexist in the same community. He provides examples of historical and contemporary empirical studies that have structured and contributed to Darwin’s theory of naturalization, Elton’s ideas about species ratios and diversity, and Gause’s competitive exclusion principle. He also highlights more recent theories of limiting similarity and priority effects, and the temporal dimensions of changes in community composition.

Guano (via Spanish, ultimately from the Quechua wanu) is the excrement of seabirds, cave-dwelling bats, pinnipeds, or (in English usage) birds in general. As a manure, guano is a highly effective fertilizer due to its exceptionally high content of nitrogen, phosphate, and potassium, three nutrients essential for plant growth. The nineteenth-century guano trade played a pivotal role in the development of modern input-intensive farming practices and inspired the formal human colonization of remote bird islands in many parts of the world. During the twentieth century, guano-producing birds became an important target of conservation programs and influenced the development of environmental consciousness. Today, guano is increasingly sought after by organic farmers. This video is targeted to blind users. Attribution: Article text available under CC-BY-SA Creative Commons image source in video

[Wikipedia] Christian Jost (geographer)
Christian H. Jost is a French Geographer. Christian (Henri) Jost is Professor of Geography and Development at the University of French Polynesia (UPF) in Tahiti (Fr) and Researcher at the Center for Insular Research and Observatory of the Environment (CRIOBE) one of France's leading laboratories for the study of coral ecosystems. After thirteen years in various position and universities in Africa (Zaïre, Rwanda, Cameroon, Togo) and two years on development projects in India (Andhra-Pradesh and Gujarat), he went as professor at the University of New Caledonia where he opened the first diploma in Geography(BSc) and spent a year as visiting fellow at Sydney University. He then went to University of Lorraine – Metz where he was Director of the Geographical Research Center from 2006 to 2011, then joined the University of French Polynesia, where he is dean of the Faculty of Human Sciences, Languages and Literature. He is associated researcher to PRODIG UMR 8586 Research unit of CNRS Paris Sorbonne 1, IV, Paris 7 universities and IRD, His research domains are on - Systems of constraints and challenges of development and environmental management in the Souths - Eco-geosystemic evolution, coastal dynamics, geopolitics and valorization of the territory of La Passion - Clipperton - Water and Risks - Island Geosystems - Sociocultural and Ecosystem Values and Indicators of Landscapes as Decision Support. Although the author of over 150 scientific papers on various subjects, Jost is particularly associated with Clipperton Island on which he is working for the past twenty years and went five times through expeditions he organized. Surveys he made there in 1997 and 2001 (confirmed in 2005) established that Clipperton is the largest colony of masked boobies in the world, with 110,000 individuals at that time. Jost was a member of SURPACLIPP, Viviane Solis-Weiss's 1997 Franco—Mexican oceanographic expedition to Clipperton (a joint venture of the National Autonomous University of Mexico and the University of New Caledonia), then led the 2001 follow-up expedition Passion 2001, which provided updated data on the geography, environment, water resources and management constraints of the atoll. In April 2015 he organized the international scientific expedition PASSION 2015 with the assistance of the French Navy and French Army and brought fourteen scientists from France, France Overseas territories and Mexico to study reef biota, coastal dynamics, flora inventory, waste inventory and fauna studies, etc. This was followed in October by an Important Colloquium he co-organized with French Deputy Deputy Philippe Folliot and CPOM ONG at the French Assemblée Nationale (Parliament). He has been widely invited to give Conferences, Master or Doctorate seminars, or participate to international Workshops and Congress, among which, Québec several universities; Rio de Janeiro, UFF, 2011 as co-organizer of the first world Congress on Risks and civil security, invited by the Charles Darwin Foundation, Galapagos at the international Workshop on sustainable development of islands facing tourism; invited by Tioumen State University, Siberia, Russia, 2010 for an international workshop on sustainable development; Agadir and Fès, Marocco, from 2008 annually for Conferences and Master courses and student field tour; Cuba, Uni. La Havanna, 2007, 2008; Hawaii, Manoa Uni. & EWC; Mexico, UNAM; Sydney, Uni. Sydney, UNSW; Suva, USP, Fiji islands; Port-Vila, Vanuatu, etc. Jost has also researched and written on other aspects of geography and ecology of the Pacific Ocean, and has worked, studied, and traveled extensively in Africa and Asia. https://en.wikipedia.org/wiki/Christian_Jost_(geographer) Please support this channel and help me upload more videos.

Biogeography | Wikipedia audio article
This is an audio version of the Wikipedia Article: Biogeography Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone. You can find other Wikipedia audio articles too at: https://www.youtube.com/channel/UCuKfABj2eGyjH3ntPxp4YeQ You can upload your own Wikipedia articles through: https://github.com/nodef/wikipedia-tts "The only true wisdom is in knowing you know nothing." - Socrates SUMMARY ======= Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, geology, and physical geography.Modern biogeographic research combines information and ideas from many fields, from the physiological and ecological constraints on organismal dispersal to geological and climatological phenomena operating at global spatial scales and evolutionary time frames. The short-term interactions within a habitat and species of organisms describe the ecological application of biogeography. Historical biogeography describes the long-term, evolutionary periods of time for broader classifications of organisms. Early scientists, beginning with Carl Linnaeus, contributed to the development of biogeography as a science. Beginning in the mid-18th century, Europeans explored the world and discovered the biodiversity of life. The scientific theory of biogeography grows out of the work of Alexander von Humboldt (1769–1859), Hewett Cottrell Watson (1804–1881), Alphonse de Candolle (1806–1893), Alfred Russel Wallace (1823–1913), Philip Lutley Sclater (1829–1913) and other biologists and explorers.
