tiger salamander life cycle

 tiger salamander
The California tiger salamander (Ambystoma californiense) is a vulnerable amphibian native to Northern California. Previously considered to be a Tiger Salamander subspecies, the California tiger salamander was recently designated a separate species again.The California tiger salamander depends on vernal pools for reproduction, its habitat is limited to the vicinity of large, fishless vernal pools or similar water bodies. It occurs at elevations up to 1000 m (3200 ft). Adults migrate at night from upland habitats to aquatic breeding sites during the first major rainfall events of fall and early winter and return to upland habitats after breeding.On August 4, 2004, the United States Fish and Wildlife Service listed the California tiger salamander as threatened within the Central Valley distinct population segment. The Santa Barbara and Sonoma County populations were returned to endangered status on August 19, 2005.
There are six populations, which are found in: (1) Sonoma County; (2) the Bay Area, (Stanislaus County, western Merced, and the majority of San Benito counties); (3) the Central Valley; (4) southern San Joaquin Valley (5) the Central Coast Range and 6) Santa Barbara County.
life cycle detals!!Adults spend the majority of their lives underground, in burrows created by other animals such as ground squirrels and gophers. the salamanders themselves are poorly equipped for burrowing. Little is known about their underground life. This underground phase has often been referred to as estivation (the summertime equivalent of hibernation), but true estivation has never been observed, and fiber optic cameras in burrows have allowed researchers to witness salamanders actively foraging. Adults are known to eat earthworms. snails, insects, fish, and even small mammals.
but adult California tiger salamanders eat very little.
Breeding takes place after the first rains in late fall and early winter, when the wet season allows the salamanders to migrate to the nearest pond, a journey that may be as far as a mile and take several days. The eggs, which the female lays in small clusters or singly, hatch after some 10 to 14 days.
The larval period lasts for three to six months. However, California tiger salamander larvae may also "overwinter". Transformation for overwintering larvae may take 13 months or more. Recent discoveries, such as overwintering, have management implications for this threatened species, particularly when aquatic habitat under goes modification. The larvae feed on other small invertebrates, including tadpoles. When their pond dries, they resorb their gills, develop lungs, and then the metamorphs leave the pond in search of a burrow.

tiger salamander utah pictures & some detals

After an evening of steady rain, which has been fairly rare in Moab this Spring/Summer, Rhonda spotted a wide-eyed little visitor looking in our back door. Over the years we have become fairly adept at identifying some of the common desert reptiles that we come across but this wet slimy thing, that appeared to be smiling at us, was outside of our experience range. Should we even touch it? Heck, most of the creatures that we have come to love in the desert are covered with sharp spines and armored skin. After a quick call to local reptile expert (and Rock Club President) Jerry Hansen, we discovered that it was a salamander, albeit a fairly large one. I managed to grab the following photos of our nighttime visitor
tiger salamander, Ambystoma tigrinum, is found in many areas of North America, and it is a common species throughout Utah. Within its range, the tiger salamander can thrive in almost any habitat type, as long as water is found nearby. Water is necessary for two reasons: 1) the larval stage of the salamander life cycle is aquatic, and 2) the terrestrial adults return to water to breed. Interestingly, the tiger salamander is the only salamander species which occurs in Utah.

Treating Betta Fish Images



The Platy fish comes in many different color varieties including the salt and pepper platies, the red wag tail and the tuxedo platy. There is even a variety called the Mickey Mouse. They can be a very active tropical fish if given good water conditions.
The female Platy is usually larger than the males of the same age. Females can reach a size of up to 2.5 inches whereas the males usually get to be about 1.5 inches. Breeding them is fairly easy since they are livebearers.
betta at the surface then you can try conditioning him by feeding the same type food consistently at the same location. If needed, try several times per day until he anticipates food at that location. If after a few days your betta hasn’t picked up on the new plan then you may want to cater to his instincts and allow the food to sink. Food that sinks won’t necessarily foul your water any quicker then floating food. The issue is rotting organic debris. As long as he is eating the food and not allowing it to decompose in the tank, you should be able to get by with your regular water changes. If your betta is leaving some food behind you can remove it 15 to 20 minutes after your initial feeding with a turkey baster. You may also want to look for other things that may be keeping him from noticing the floating food, like bright overhead lighting, Add “Fungus Eliminator” by Jungle (included in our Betta First Aid Kit). These are crystals are dosage should be about 30-40 grains per 1/2 gal. Water should have a nice gold color, not too dark. Do not overmedicate! Change water every third day and add a new dose of same medication. Continue until all fungus has disappeared. Then switch to BettaZing (8 drops per gallon) to clean any other bacteria/fungus that may still be present. for very stubborn or very fast invasive fungus use: Fungus Eliminator AND Bettazing TOGETHER, both at full dosage.

Venezuela Jungles

findings and carbon-dating evidence indicate that human settlements here can be traced back to 13,000 BC. the defeat of the Spanish by Simon Bolivar and his armies in 1819, it, along with Colombia, Ecuador, and Panama, formed the independent Republic of Gran. Venezuela emerged from that coalition in 1830. popular election of President Hugo Chavez in 1999 has now caused considerable controversy, especially within the United States, as Venezuela has some of the largest proven oil reserves outside of the Middle East and President Chavez is using same as a regional threat and bargaining chip. finally, the country is still feeling the devastating impact of (Hurricane Mitch, October 1998), when at least 5,000 people died in Venezuela's worst natural disaster in a half-century.

Virunga national park congo & virunga Gorilas pics

Virunga National Park (French: Parc National des Virunga), formerly named Albert National Park, lies from the Virunga Mountains, to the Rwenzori Mountains, in the eastern Democratic Republic of Congo, bordering Volcanoes National Park in Rwanda and Rwenzori Mountains National Park in Uganda. The Ruwenzori Mountains lie on the Ugandan border and rise to alpine meadows and a glacier, while Nyiragongo and Nyamuragira are both active volcanoes with substantial associated lava plains. The neighbouring Mount Hoyo area was managed with the park and is home to a population of Bambuti Pygmy people, caves and waterfalls, but since the civil wars, the park has suffered somewhat. Land invasions and intense poaching have challenged the park authorities to the limit, but most rangers have remained active. Since 1994, about 120 rangers have been killed in the line of duty protecting the park from illegal poaching and land acquisition. Amongst other military activity, the Democratic Forces for the Liberation of Rwanda or FDLR has been using the park as a safe location when they have come under sustained attack, such as Laurent Nkunda's offensives against them in April-May 2007.
