Description and Ecology of Fin Whales 

1. Also called the Finback whale, the Razorback, or the Common Rorqual

2.  A Fin Whale is in the suborder of baleen whales, which means that it is a widely distributed order of carnivorous marine mammals

3. They are the SECOND LARGEST animal in the world, second only to blue whales! 

4. Can grow to be 89.6 feet long and the average weight is 163,096 pounds. The maximin recorded weight is 2,204 pounds

5. They have a slender body that is built like a racing yacht and they can surpass even the fastest ocean steamship, getting up to speeds of 23 mph. They are brownish-grey in color and has a prominent curved) dorsal fin located at the back of their bodies

6. Their diet consists of krill, small schooling fish (for example: herring, capelin, and sand lance), and squid. They fast all throughout the wintertime. Fin Whales have been observed circling schools of fish at incredibly high speeds, then rolling the fish into compact balls, and turning over to lay on their right side in order to eat the fish that they catch

7. Fin Whales can live 80-90 years!

8. There are two named subspecies of fin whale: physalus physalus in the North Atlantic ocean and physalus quoyi in the Southern Ocean

9. Genetic Analysis is a major way to study Fin Whales at different locations to find out which groups are interbreeding and which are not. Scientists use sound as a tool to study these whales  

10. Only the males produce sound (in order to find mates or mark their territory). Different packs of whales "speak a different dialect" depending on where they are from (make different sounds due to their different locations) 

11. Fin Whales hum at such a low pitch that humans can not even hear them without using a hydrophone (which is an underwater microphone that picks up noise and translates it to a computer for people to decipher) 

12. Fin whales are found alone most often, but groups of 3-7 whales are common. Groups of larger numbers sometimes occurs in some areas

Geographic and Population 

1. There are currently believed to be less than 100,000 to roughly 119,000 Fin Whales worldwide (were almost extinct but their numbers have risen greatly in the recent past) 

https://en.wikipedia.org/wiki/Fin_whale

2. Live in deep, offshore waters of all major oceans, primarily in temperate to polar latitudes, and  less commonly in the tropics

These two websites allow you to search for a particular animal and then enables you to see where they live in the world: http://iobis.org and http://www.gbif.org/species/7194022

Listing Date and Type of Listing

1. Fin Whales have been listed as “endangered” since 1970 under the precursor to the Endangered  Species Act (ESA) and have remained on the list of threatened and endangered species since the ESA was passed in 1973 (35 FR 8491; June 2, 1970)

2. Type of listing: endangered 

Cause of Listing and Main Threats to its continued existence 

1.  Populations majorly depleted by modern whaling practices and hunted for oil, their meat, and baleen

2. Commercial whaling for this species ended in the North Pacific in 1976, in the Southern oceans in 1976–77, and in the North Atlantic in 1987

3. Fin whales are still hunted in Greenland, which falls under the International Whaling Commission’s (IWC) “aboriginal subsistence whaling” scheme 

4. Iceland resumed commercial whaling of Fin whales in 2006 under a formal objection to the IWC’s ban on commercial whaling and Japan kills Fin whales as part of its scientific whaling program, as well as to be sold in Japanese markets for oil and meat

5. The IWC issued a moratorium on commercial hunting of this whale, but Iceland and Japan have resumed hunting

6. The main threats to Fin Whales are collisions with vessels/ships, direct harvest/hunting, and competition among them and other animals for resources, such as food, loss of prey due to climate change, and disturbance from anthropogenic noise 

Recovery Plan

1. Coordinate State, Federal, and International Actions to Implement Recovery Actions and Maintain International Regulation of Whaling for Fin Whales

2. Determine Population Discreteness and Population Structure of Fin Whales

3. Develop and Apply Methods to Estimate Population Size and Monitor Trends in Abundance

4. Conduct Risk Analyses

5. Identify, Characterize, Protect, and Monitor Habitat Important to Fin Whale 

http://indonesiaglory.com/all-about-fin-whale/

6. Populations in U.S. Waters and Elsewhere

7. Investigate Causes and Reduce the Frequency and Severity of Human-caused Injury and Mortality

8. Determine and Minimize Any Detrimental Effects of Anthropogenic Noise in the Oceans

9. Maximize Efforts to Acquire Scientific Information from Dead, Stranded, and Entangled or Entrapped Fin Whales

10. Develop Post-Delisting Monitoring Plan

This plan not a perfect list of ideas but instead it is used to identify actions that will minimize or hopefully eliminate the negative effects of human activities that are detrimental to the recovery of Fin Whales. Immediate objectives of this list are to identify all of the negative factors that may be stunting the abundance/recovery/productivity, and describe actions necessary for the populations increase. This plan stresses the absolute importance of a multinational approach to management and recovery. This is due to the fact that Fin Whales move across international borders that are through the oceans 

What can YOU do?

1. The most important part of the recovery plan that normal, typical people can do to help these whales is to support existing studies, help initiate and support new studies that investigate population discreteness and population structure of Fin Whales using genetic analyses

2. Don’t hunt them for oil, meat, and baleen

3. Support WWF and International Whaling Commission

4. Adopt a whale 

5. Join the MarineBio Conservation Society or donate monthly

The Southern Tiger Cat by Will Doerr

The Southern Tiger Cat (Leopardus guttulus
Date Listed: May 10, 2014
Listing: Vulnerable

Summary:

            The Southern Tiger Cat exists primarily in South American countries including Brazil, Paraguay, and northeastern Argentina. Leopardus Guttulus prefers elevations at around 2,000 feet and enjoys being shrouded by surrounding forests and jungles. The cat is carnivorous, including small rodents as a main part of its diet. They normally range from 35cm to 60cm and weigh up to 3kg. In captivity these cats can live up to 23 years, in the wild their lifespan is 10 to 14 years, but because of recent exploitation of their fur and habitat, their lifespans are cut nearly in half. (Cats.org) As of now, there are an estimated 6,047 mature individuals in the wilderness. In protected areas, scientists predict a decline of 10% of the total population over the next fifteen years, putting it in the endangered zone.

Population:

As mentioned before, the Southern Tiger Cat lives in northeastern South America. It’s primary breeding grounds exist in Santa Catarina, Brazil, where it is the safest due to high conservation efforts. Most conservation units in Brazil house 500 Southern Tiger Cats or less, limiting the ability to study them truly. The spread of Leopardus Gluttus reaches maximums of 91 per ever 100 square kilometers. Where the Southern Tiger Cat has to compete with Ocelots, its population density falls to a mere 1-5 per every 100 square kilometers. The total population of the Southern Tiger Cat lies at 6,047 and is declining as a result of competition with Ocelots, poaching, and habitat destruction. 

Listing and Threats:

The Southern Tiger Cat is listed as a vulnerable species with a declining population. It received this listing because it is seen as relatively stable, but is still declining. Also, it is a very small populated species to begin with, leaving the Tiger Cat to heavy risk. The leopardus gluttus was listed in May of 2014, just a few years after it was recognized as its own species.

The Southern Tiger Cat faces several threats. One threat are poachers, who hunt them for their fur which closely resembles that of an Ocelot. Another threat includes deforestation of their habitat, this removes their home and population of prey. Tiger Cats are also occasionally killed by rural farmers who want to protect their properties.

Actions to Take:

Actions being taken right now are making the trade of Leopardus Gluttus fur illegal. Although many of the trading happens on the black market, it is easier to manage and prosecute when the fur is explicitly non-commercial. The best action being taken as of now is conservation of the animal’s habitat. Scientists and the government has made the best effort to protect the land and allow the tiger cat to prosper.


Actions You Can Take: 

As of now the best action to take for the average individual is to donate to the conservation efforts of the South American Governments and other conservation groups.

Utah Prairie Dogs, Almost Lost Forever

Utah Prairie Dogs, Almost Lost Forever
By Charlie Duysen


Prairie dogs are unique in that they are only found in North America. They are closely related to rodents and in the same family as squirrels. There are actually five different species of prairie dogs found in North America, which include the Utah prairie dog, the white-tailed prairie dog, the black-tailed prairie dog, the Gunnison prairie dog, and the Mexican prairie dog.


One of these species of prairie dogs, the Utah Prairie Dog (Cynomys parvidens), was unfortunately listed on the Endangered Species act and later labeled as a Threatened Species. Primarily in southwest Utah, the Utah Prairie Dog can be found in a variety of landscapes, including arid grasslands, edges of Ponderosa pine stands, agricultural fields, and urban areas. The Utah Prairie Dog is considered a social animal, as it lives in coteries, which are essentially small family groups. In a typical coterie, one may find an adult male, one to three adult females, and their associated offspring. The Utah Prairie Dog is a relatively small mammal, roughly 12-14 inches in length and weighing about 1-3 pounds. Their fur varies in color, but generally is a combination of shades of brown and black. Mainly herbivores, these prairie dogs feed on grass, seeds, leaves, flowers, and the occasional insect, such as the cicada. As a burrowing animal, these prairie dogs use their extensive underground tunnel system to their advantage, offering protection from potential predators. Their burrows can be 5-10 meters long and 2-3 meters deep, with at least two entrances/exits.

In Utah in the 1920s, it is estimated there were 95,000 Utah Prairie Dogs. By 1972, that number dropped significantly to 3,300. Due to a multitude of factors, specifically disease, over-exploitation, predation, and habit destruction and modification, it was estimated in 1972 that the entire species would be extinct by 2000. On June 4th, 1973, the Utah Prairie Dog was officially listed as an extinct species, in accordance with the Endangered Species Conservation Act of 1969.


However, the Utah Prairie Dog transitioned from an Endangered Species to a Threatened Species on May 29th, 1984. The prairie dogs began to increase in population on private lands, slowly reestablishing stability as a species. In addition, one major contributing factor to the prairie dog’s resurgence occurred in 1972, when the Utah Division of Wildlife Resources enacted a program, relocating prairie dogs in private lands to public lands where they historically used to reside. The combination of prairie dogs reappearing on private lands, and the reestablishment of these mammals onto public lands was what enabled the transition from Endangered to Threatened. Now, as of 2014, it is estimated that there are around 22,000 Utah prairie dogs occupying habitat on both protected federal and non-federal lands, as well as non-protected lands in general.
           
            There’s no question that the prairie dogs thriving in Western America today can thank the Recovery Plan of 1991. The recovery plan for the Utah Prairie Dog was finalized in 1991 and revised in 2012. The recovery plan was multifaceted, but essentially focused on maintaining and protecting the current prairie dog habitats, as well as establishing additional colonies. An example of a portion of the plan was continuing the annual surveys and population monitoring of the Utah Prairie Dogs, improving their habitat on federal land by adding/treating certain vegetation, and improving relations with private landowners to increase conservation.
           

            All though it is estimated that the Utah Prairie Dog only occupies about 10% of its historic range, one may recall that they were predicted to go exist by 2000, so their mere existence today could be looked at as a victory. These Utah Prairie Dogs are still susceptible to plague, urban expansion, over-grazing, cultivated agriculture, vegetation community changes, invasive plants, climate change, energy resource exploration and development, fire management, poaching, and predation, so our effort to continue helping them is absolutely necessary. Personally, due to obvious restrictions, I am unable to physically play an influential role in helping out these mammals. However, I am perfectly capable of raising awareness about these animals and their current status of being a threatened species. If others hear of this problem, they will be more inclined to help out, whether it be donating money to the government or assisting me in raising awareness. Hopefully the laws and boundaries protecting these mammals continue to act as an effective preservation and conservation method, and we continue to see Utah Prairie Dog’s presence among us.
