The Lionfish Info Sheet: Captive Care and Home Husbandry by Frank Marini, Ph.D. - Reefkeeping.com
Lions and triggers and eels…oh my! Nothing embodies both the beauty and danger of the oceans more than lionfish. Not only are they astonishingly beautiful with their gracefully flowing fins, dramatic colorations, cautious movements, and fish-gulping mouths, but they're equipped with venomous spines capable of delivering painful stings upon an unwary hobbyist. In spite of all this bravado, lionfish are peaceful, extremely hardy and disease-resistant tank inhabitants that are well suited for the intermediate saltwater hobbyist.

Lionfish, Lionfish Profile, Facts, Information, Photos, Pictures, Sounds, Habitats, Reports, News - National Geographic
Pretty much everything about the venomous lionfish—its red-and-white zebra stripes, long, showy pectoral fins, and generally cantankerous demeanor—says, "Don't touch!" The venom of the lionfish, delivered via an array of up to 18 needle-like dorsal fins, is purely defensive. It relies on camouflage and lightning-fast reflexes to capture prey, mainly fish and shrimp. A sting from a lionfish is extremely painful to humans and can cause nausea and breathing difficulties, but is rarely fatal. Lionfish, also called turkey fish, dragon fish and scorpion fish, are native to the reefs and rocky crevices of the Indo-Pacific, although they've found their way to warm ocean habitats worldwide.

SpringerLink - Journal Article
Abstract Less than a decade after being observed off Florida, the invasive Indo-Pacific lionfish is now widely distributed off the southeast coast of the United States. As a step towards measuring invasion impacts to native communities, we examine the magnitude and extent of this invasion by first, compiling reports of lionfish to provide range information and second, estimate lionfish abundance from two separate studies. We also estimate native grouper (epinepheline serranids) abundance to better assess and compare lionfish abundances. In the first study we conducted SCUBA diver visual transect surveys at 17 different locations off the North Carolina coast in water depths of 35–50 m. In the second study, we conducted 27 Remote Operated Vehicle (ROV) transect surveys at five locations from Florida to North Carolina in water depths of 50–100 m. In both studies, lionfish were found to be second in abundance only to scamp (Mycteroperca phenax). Lionfish were found in higher abundance in the shallower North Carolina SCUBA surveys ( ha−1) than in the deep water ROV surveys ( ha−1). Lionfish reports continue to expand most recently into the Bahamas, raising the specter of further spread into the Caribbean and Gulf of Mexico. The potential impacts of lionfish to native communities are likely to be through direct predation, competition and overcrowding. The high number of lionfish present in the ecosystem increases the potential for cascading impacts throughout the food chain. Within the southeast region the combined effects of climate change, overfishing and invasive species may have irreversible consequences to native communities in this region.

Science Centric | News | Invasion of predatory lionfish in the Caribbean threatens coral reefs
The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems - a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent.

NOAA National Ocean Service Education: Lionfish Discovery Story
Most scientists agree, it is unlikely that the lionfish's invasion of U.S. waters can be reversed. Any large-scale attempts to remove the existing lionfish from U.S. Atlantic waters appear impractical and would be very costly, because of the large geographic range and depths that the fish now occupies. Lionfish are now found along the entire southeast U.S. coastline at depths between 80 and 260 ft, making their complete removal all but impossible. Scientists point out that the introduction and spread of the lionfish illustrate the difficulty of managing introduced species in the marine environment. Lionfish now join the ranks of other aquatic invasive species that have taken up permanent residence in U.S. waters, such as European green crabs, Asian eels and zebra mussels.

Women who Become Men: Albanian Sworn ... - Búsqueda de libros de Google
Most people conceive of gender as a culturally informed response to a biological imperative. But such rigid notions are overturned by certain women in remote regions of Albania who elect to 'become' men simply for the advantages that accrue to them as a result. They crop their hair, wear men's clothes, roll their own cigarettes, drink brandy and carry guns. In short, their lives are much freer and less regimented than other members of their sex - but at a cost. These women must foreswear sexual relationships, marriage and children. They have been dubbed 'Sworn Virgins'.What is interesting is that in this region of the Balkans, simply to dress as a man and to behave as a man will earn these women the same respect accorded a man. This is no mean advantage in an area known for sexual inequality and where so many men have suffered violent, premature deaths, thereby heightening the need for more household heads. Traditionally as heads of household, men are revered and the women who attend them utterly subservient. But unlike 'normal' women, Sworn Virgins can inherit and manage property, and, in fact, may even be raised to assume the male role by parents who have no male heirs.Based on extensive interviews, this book tells the frank and engrossing stories of these women, but also sets their lives within the wider context of a country undergoing radical upheaval and social transformation.

Nuevas claves sobre el enigma de Kafka · ELPAÍS.com
Los eruditos de Kafka ya se frotan las manos. En la planta baja de un viejo edificio de apartamentos del centro de Tel Aviv podría hallarse la clave definitiva para resolver las dudas sobre la vida y la obra de Franz Kafka (1883-1924), uno de los más grandes narradores del siglo XX y también uno de los más misteriosos. Varios investigadores están convencidos de que en ese lugar se encuentran los restos del legado del autor, un conjunto de documentos, cartas, postales, dibujos y otros objetos personales, según informa el diario israelí Haaretz, que podrían arrojar nueva luz sobre el solitario autor que escribió los inquietantes La metamorfosis, El proceso y En la colonia penitenciaria, entre otras novelas y cuentos extraordinariamente singulares.

Corals, Already in Danger, Face New Threat in Algae Grown by People - NYTimes.com
Corals are being covered and smothered to death by a bushy seaweed that is so tough even algae-grazing fish avoid it. It settles in the reef’s crevices that fish once called home, driving them away. Dead coral stops supporting the ecosystem and, within a couple of decades, it will crumble into rubble, allowing big ocean waves to reach the beach during storms and destroy the flimsy thatched huts of the Micronesians. “We are catching less and less fish, and the seaweeds are fouling our nets,” says Henry Totie, a fisherman and Butaritari’s traditional chief, in an interview in his traditionally built house in the village near the blue-green lagoon.

PickensPlan
America is in a hole and it's getting deeper every day. We import 70% of our oil at a cost of $700 billion a year - four times the annual cost of the Iraq war. I've been an oil man all my life, but this is one emergency we can't drill our way out of. But if we create a new renewable energy network, we can break our addiction to foreign oil. On January 20, 2009, a new President gets sworn in. If we're organized, we can convince Congress to make major changes towards cleaner, cheaper and domestic energy resources.

NATHANIEL LORD BRITTON RECORDS
Nathaniel Lord Britton (1859-1934), the first Director of the New York Botanical Garden, was born on 15 January 1859 at New Dorp, Staten Island, New York, son of Jasper Alexander Hamilton Britton and Harriet Lord Turner. His parents envisioned a religious career for their son; instead, John J. Crooke and John Strong Newberry, two "all-around naturalists" of Staten Island, nurtured his native curiosity about the natural world and guided him easily into a botanical career. From the beginning Britton created a sizeable botanical collection, and his father reinforced his interest with visits to the Columbia College herbarium. As the young Britton's education progressed at the Staten Island Academy, Crooke, a neighbor of the Brittons, convinced his parents to allow him to attend the Columbia College School of Mines.

A Ban on Cockfighting, but Tradition Lives On - NYTimes.com
Circulation of the country’s largest trade magazine for cockfighting, The Gamecock, has fallen to 8,000 from about 14,000 over the last decade as states strengthened penalties for animal cruelty. And the wider cockfighting community, once an $80 million industry in the state, is suffering. In New Mexico, profits at feed stores and hotels in cockfighting strongholds are down as much as 70 percent, owners said.

Este escritor es un visionario · ELPAÍS.com
Es un miércoles cualquiera, soleado y ventoso, en la calle Valencia, de San Francisco. Otro día más en el seno de la revolución literaria de Dave Eggers (Chicago, 1970), filántropo, infatigable aglutinador de voluntades y muy probablemente el escritor estadounidense más relevante de su generación. No son sólo sus novelas (Mondadori acaba de publicar Qué es el qué, la tercera). Es la decena de proyectos sociales que abandera repartidos por todo el país. Son sus incomparables revistas. Es, en suma, el imperio de ideas ingeniosas que Eggers controla desde un anónimo edificio, indistinguible entre las taquerías y los negocios latinos de esta arteria del barrio mexicano de The Mission.
