In addition to this, the utilizations of natural resources in mangrove ecosystem, especially flora and fauna in it, through various human activities, lead to the degradation of the mangrove forest. Also, the decreasing of some important species such as Painted terrapin ( Batagur borneoensis ), called Tuntong Laut by local people. In view of this, Lembaga SatuCita conducted a conservation initiative since 2009 to conserve that species, both through in-stiu and ex-situ method. This initiative run some activities: nesting patrol, educational program, field survey, field research, headstarting program. We save the Painted terrapin from any threats in Seruway and make efforts to assurance them in their native habitat. This book is a book published by Lembaga SatuCita to increase the student awareness and knowledge about this species. We can say that this is a handbook. This handbook is bilingual language: English and Bahasa Indonesia. By publishing this book and educating the students about the contents of this book, we aim that in the student, our future generation, will have knowledge about this species. So, this species will be a considerance in their decision. The future of Painted terrapin is very influenced by the decision made by young generation. We would like to take this opportunity to sincerely thank Keidanren Nature Conservation Fund (KNCF) for its financial support to publish this book and to implementing our educational program (campaign) to student. This campaign targeting 600 students in junior and senior high school. I also would like to thank to staff and volunteer in Lembaga SatuCita “we can save Painted terrapin!”. Finally also would like to thanks Prof. Chan Eng Heng and Chen Pelf Nyok from Turtle Conservation Centre Kuala Terangganu Malaysia (all of your advices and comments has made this initiative is possible), to local forestry officer, local traditional institution called Panglima Laot, Datuk Laksamana, teachers in targeted schools. All of you has provided valuable information to the book.

Definition of Mangrove Forest According Nybakken (1992), mangrove forests are the common word used to describe a variety of tropical coastal communities are dominated by several species of trees or shrubs characteristic that has the ability to grow in salty waters. Mangrove forests include trees and shrubs are classified into 8 families, and consists of 12 genera of flowering plants: Avicennie, Sonneratia, Rhyzophora, Bruguiera, Ceriops, Xylocarpus, Lummitzera, Laguncularia, Aegiceras, Aegiatilis, Snaeda, and Conocarpus (Bengen, 2000). Picture 1.1.1. Mangrove Forest in Seruway, Aceh Tamiang The word mangrove has two meanings, first as a community, the community or communities or forest plants that are resistant to salinity / salinity (tidal), and second as an individual species (Macnae, 1968 in Supriharyono, 2000). In order not to be confused, Macnae use the term "Mangal" when associated with forest communities and " mangrove " for individual plants. Mangrove forests by local people often called the Mangrove forest or swamp forests. But according Khazali (1998), the mention of mangroves as Bakau (Bahasa Indonesia) seems less appropriate because the Bakau are one of group names of plant species found in mangroves. Adaptation of Mangrove Faced with the extreme environment in mangroves, plants adapt to a variety of ways. Physically, the most typical mangroves are to grow specific organs for their survival, such as various forms of roots and salt glands in the leaves. But there are also other forms of physiological adaptation. Avicennia grows at the river side. Notice the breathing roots that appear to the mud beach. Mangrove trees ( Rhizophora spp. ), which usually grow in the outer zone, develop Let us save Painted terrapin in Aceh Tamiang 3 stilt root to survive the fierce waves. The types of Avicennia spp. and Sonneratia spp developing their breath roots (pneumatophore ) arising from the mud to take oxygen from the air. The Bruguiera spp . has a knee root, while the trees Nirih ( Xylocarpus spp. ) with their winding roots, both of them are to support the tree upright in the mud, while also getting air for breathing. Plus many other types of mangrove vegetation has lenticels , pore holes to breathe .To cope with high salinity, fires remove excess salt through glands on the bottom leaves. While other types, such as Rhizophora mangle , developed a root system that almost impenetrable to salt water. Water that has absorbed almost tasteless, approximately 90-97% of salt content in sea water could not pass through the filter of this root. The salt was contained in the body of plants, accumulated in old leaves and leaf drop will be wasted together. On the other hand, given the difficulty of obtaining fresh water, mangrove vegetation should seek to maintain the water content in the body. Though the tropical ocean environment encourages high heat of vaporization, several types of mangrove plants are able to set the mouth opening of leaves ( stomata ) and the direction toward the surface of the leaves in the daytime heat, thus reducing evaporation from the leaves. Breeding Another important adaptation is shown in terms of breeding species. Harsh environments in mangroves almost impossible to grains germinate normally on the mud. In addition to the extreme chemical conditions, physical condition of the tidal mud and sea water makes difficult to maintain seed viability. Almost all types of flora of mangroves have seeds or fruits that can float, so it can be dispersed by the flow of water. In addition, many of the mangrove species are viviparous : the seed or seeds have germinated before the fruit fall from trees. The most famous example is perhaps the germination of the fruits of Bakau ( Rhizophora ), Tengar (Ceriops ) or Kendeka ( Bruguiera ). Fruit trees have germinated and issued a similar length of the spear when the roots are still dependent on the stalk. When they fall, these fruits can be directly embedded in the mud at the crash site, or carried off the tide, caught and grown in other parts of the forest. Alternatively, the sea swept away and travel to distant places. Fruit palm ( Nypa fruticans ) has emerged in the bud while still attached in it stem. While fruit of Avicennie , Kaboa ( Aegiceras ), Jeruju ( acanthus ) and several others have also germinate on the tree, although not visible from the outside. These privileges were no doubt increase the successness of the seeds to grow. Children's nursery with the terms of this kind are called propagule. This propagules can be carried away by ocean and waves up to miles and miles away, maybe even across the sea or strait with a collection of other marine debris. Propagules can 'sleep' (dormant) for days and even months, during a trip to arrive at a suitable location. If it will grow settled, several types of propagules can change the ratio of the weight of his body parts, so that the roots begin to sink and propagules floating vertically in the water. This makes it easier for the entangled and stuck in the muddy bottom of shallow water. Let us save Painted terrapin in Aceh Tamiang 4 Mangrove Forest Succession The growth and development of a forest known as forest succession (forest succession or sere ). Mangrove forest is an example of forest succession in wetlands (called hydrosere ). Given this succession process, please note that the zoning of mangrove forests in the above description is not eternal, but gradually shifted. Succession begins with the formation of an exposure to mud (mudflat) that can serve as a substrate mangroves. Until in a one time, this new substrate was invaded by propagules of mangrove vegetation. Then, begin to form a pioneer vegetation of mangrove forests. The growth of mangrove forests are caught somewhere in mud. Fine soil that washed out the river flow, the sands carried by ocean flow, all sorts of rubbish and destruction of vegetation, will be deposited in the roots of mangrove vegetation. Thus, the mud will gradually accumulate more and more and faster. Mangroves are also more widespread. At the time, the mangrove forests will begin to dry out and become no longer suitable for the growth of pioneer species such as Avicennia alba and Rhizophora mucronata .

Email: [email protected] The Willow Creek Riparian Preserve (Preserve) is a privately owned 130-acre site located 30 miles east of Kingman, Arizona. The Preserve was formally established in 2007 with the purchase of 10-acres and an agreement with the eastern adjoining private landowner to add an additional 120-acres. The Preserve location was unfenced and wholly accessible by livestock, off-road vehicle use, and hunting. In October of 2008 the Preserve was fenced with volunteer efforts from the local Rotary Club and Boy Scout Troop 66. Additional financial assistance came through a large discount in the cost of fencing materials from Kingman Ace Hardware. A total of 0.5-linear mile of new wildlife friendly fencing (barbless top wire and 18-inches above-ground bottom wire) was installed along the south and west sides and connected to existing Arizona State Lands cattle allotment fencing. Baseline and on-going studies and data collection have occurred since 2004. These have included small mammal live trapping; chiropteran surveys with the use of Anabat; migratory, breeding, and winter avian surveys; amphibian and reptile surveys; deployment of game cameras; animal track and sign identification and movement patterns; vegetation and plant surveys; and a wetland delineation.

Results yielded a robust support to the monophyly of a group (Cuora group) consisting of Cuora sensu lato and the monotypic Pyxidea. Within the Cuora group, the continental Cuora (sensu stricto) and the two subspecies of Ci. flavomarginata constituted two well-supported monophyletic groups. Distinctly small interspecific genetic distances in the former groups suggested that in the continent speciations in Cuora took place much later than the primary divergences in the Cuora group, or speciations in other related genera, such as Mauremys. Our analyses failed to provide a substantial support to the monophyly of any other combinations of taxa within the Cuora group, including Cuora in broad and strict senses, and Cistoclemmys as consisting of Ci. galbinifrons and Ci. flavomarginata. Besides these, our results also suggested the non-monophyly for the Batagurinae and the Geoemydinae, and sister relation- ships of the Bataguridae with Testudinidae rather than with the Emydidae.

  • Effects of Age on Hummock Succession in Bogs
    Effects of age on hummock succession in bogs By Joel Vallier Abstract Ecological succession is the change in communities over time. We chose to study the successional stages of hummocks in a bog using age. We hypothesized that hummock plant richness should increase then decrease with age because of successional flora species mixing. We also hypothesized that hummock density, and hummock size will increase with age. Our study site was a bog at Mud Lake located in Cheboygan County, Michigan. We set up two 100 meter transects, divided them into zones based on age then recorded hummock surface area and hummock density. Plant richness was also recorded. There was a significant difference in plant richness with hummock age but only when surface area was used a covariant. Surface area was not significantly different among different aged zones. Hummock density did not have any correlation with age. Places were successional flora species mixed provided more plant richness and also showed trends of higher surface area. The tree line altered our results in the youngest zones because it had late successional species mixed with early successional species. This gave one of our youngest zones the highest plant richness. This shows that trends exist between hummock size, and plant richness but the surrounding morphology has a large impact. Introduction Succession within an ecological community is the change in species composition over time. This can change the biodiversity of the environment by altering conditions making it more adaptable by other species (Katz, 1926). This can be seen in the classic hydrosere succession model, where infilling of a shallow lake by sediments produces a sequential trend of vegetation communities staring with marsh shrub and moss species and ending with climax forests composed mostly of woody species (Klinger, 1996).

  • Chapter 5: Vegetation of Sphagnum-Dominated Peatlands
    CHAPTER 5: VEGETATION OF SPHAGNUM-DOMINATED PEATLANDS As discussed in the previous chapters, peatland ecosystems have unique chemical, physical, and biological properties that have given rise to equally unique plant communities. As indicated in Chapter 1, extensive literature exists on the classification, description, and ecology of peatland ecosystems in Europe, the northeastern United States, Canada, and the Rocky Mountains. In addition to the references cited in Chapter 1, there is some other relatively recent literature on peatlands (Verhoeven 1992; Heinselman 1963, 1970; Chadde et al., 1998). Except for efforts on the classification and ecology of peatlands in British Columbia by the National Wetlands Working Group (1988), the Burns Bog Ecosystem Review (Hebda et al. 2000), and the preliminary classification of native, low elevation, freshwater vegetation in western Washington (Kunze 1994), scant information exists on peatlands within the more temperate lowland or maritime climates of the Pacific Northwest (Oregon, Washington, and British Columbia). 5.1 Introduction There are a number of classification schemes and many different peatland types, but most use vegetation in addition to hydrology, chemistry and topological characteristics to differentiate among peatlands. The subject of this report are acidic peatlands that support acidophilic (acid-loving) and xerophytic vegetation, such as Sphagnum mosses and ericaceous shrubs. Ecosystems in Washington state appear to represent a mosaic of vegetation communities at various stages of succession and are herein referred to collectively as Sphagnum-dominated peatlands. Although there has been some recognition of the unique ecological and societal values of peatlands in Washington, a statewide classification scheme has not been formally adopted or widely recognized in the scientific community.

  • MAHS Care Sheet Master List *By Eric Roscoe Care Sheets Are Often An
    MAHS Care Sheet Master List *By Eric Roscoe Care sheets are often an excellent starting point for learning more about the biology and husbandry of a given species, including their housing/enclosure requirements, temperament and handling, diet , and other aspects of care. MAHS itself has created many such care sheets for a wide range of reptiles, amphibians, and invertebrates we believe to have straightforward care requirements, and thus make suitable family and beginner’s to intermediate level pets. Some species with much more complex, difficult to meet, or impracticable care requirements than what can be adequately explained in a one page care sheet may be multiple pages. We can also provide additional links, resources, and information on these species we feel are reliable and trustworthy if requested. If you would like to request a copy of a care sheet for any of the species listed below, or have a suggestion for an animal you don’t see on our list, contact us to let us know! Unfortunately, for liability reasons, MAHS is unable to create or publish care sheets for medically significant venomous species. This includes species in the families Crotilidae, Viperidae, and Elapidae, as well as the Helodermatidae (the Gila Monsters and Mexican Beaded Lizards) and some medically significant rear fanged Colubridae. Those that are serious about wishing to learn more about venomous reptile husbandry that cannot be adequately covered in one to three page care sheets should take the time to utilize all available resources by reading books and literature, consulting with, and working with an experienced and knowledgeable mentor in order to learn the ropes hands on.

Each lagoon has distinct ecological characteristics, and these sites also serve as popular tourist attractions because they are common habitats for migratory birds and are characterized by beautiful natural scenery. Lagoons also have distinct ecological characteristics from those of their associated estuaries, and there are active research efforts to classify, qualify, and quantify the high biodiversity of lagoons. The lagoons in Korea are primarily distributed in the East Sea, and are represented by Hwajinpo, Yeongrangho, and Gyeongpoho. Here, we report the discovery of 11 unrecorded diatom species (Diploneis didyma, Mastogloia elliptica, Cosmioneis citriformis, Haslea crucigera, Pinnularia bertrandii, Pinnularia nodosa var. percapitata, Gyrosigma sinense, Gomphonema guaraniarum, Gomphonema italicum, Navicula freesei, Trybionella littoralis var.

Read Full License Page 1/14 Abstract The Red-crowned roofed turtle (Batagur kachuga) and Three-striped roofed turtle (B. dhongoka) are ‘critically endangered’ turtles in the Geoemydidae family. Herein, we generated the novel mitochondrial genome sequence of B. kachuga (16,155) and B. dhongoka (15,620) and compared it with other turtles species. Batagur mitogenome has 22 transfer RNAs (tRNAs), 13 protein-coding genes (PCGs), two ribosomal RNAs (rRNAs), and one control region (CR). The genome composition was biased toward A + T, with positive AT-skew and negative GC-skew. In the examined species, all 13 PCGs were started by ATG codons, except COI gene, which was initiated by GTG. The majority of mito-genes were encoded on the heavy strand, except eight tRNAs and the ND6 region. We observed a typical cloverleaf structure for all tRNA, excluding tRNASer (AGN), where the base pairs of the dihydrouridine (DHU) arm were abridged. Bayesian Inference (BI) based phylogenetic analysis was constructed among 39 species from six Testudines families, exhibited a close genetic relationship between Batagur and Pangshura with a high supporting value (PP ~ 0.99).
