experiment research



You have conduct an experiment research about Temperature Preference of Fish. Would you give:
1). Hypothesis of experiment
2). The basis theory of your hypothesis
Hypothesis experiment :
The behavior of guppies (Poecilia reticulata) will change along with the changes in the surrounding temperature. And he will choose the place where he lives in accordance with the existing temperature level.
Basic theory :
       The success of an organism to survive and reproduce reflect the overall tolerance of the whole set of environment variables faced by these organisms, This means that every organism must adapt to the environmental conditions. Adaptation responses in the form of morphological, physiological and behavioral. In the marine environment, physical, chemical and biological role in the homeostasis necessary. for the growth and reproduction of aquatic biota (Tunas, 2005).
           Temperature is an important factor in aquatic ecosystems (Ewusie, 1990). The increase in water temperature can be cause life of fish and other aquatic animals disturbed (Aprianto and Liviawati, 1992). According Soetjipta (1993), water has several unique thermal properties, so that changes in the temperature of the water runs more slowly than air. Furthermore Soetjipta added that although the temperature is less volatile in water daripadadi the air, but the temperature is a major limiting factor. Therefore, aquatic creatures often have narrow tolerances.

relung multidimensi

1) Hutchinson menjelaskan konsep "relung multidimensi" apakah yang dimaksud dengan relung multidimensi? bagaimana kaitannya dengan adaptasi thdp faktor lingkungan? Hutchinson (1957) dalam Begon,et al (1986) telah mengembangkan konsep relung ekologi multidimensi (dimensi-n atau hipervolume). Setiap kisaran toleransi hewan terhadap suatu faktor lingkungan, misalnya suhu merupakan suatu dimensi. Dalam kehidupannya hewan dipengaruhi oleh bukan hanya satu faktor lingkungan saja, melainkan bannyak faktor lingkungan secara simultan. Faktor ligkungan yang mempengaruhi atau membatasi kehidupan organisme bukan hanya kondisi lingkungan seperti suhu, cahaya, kelembapan, salinitas tetapi juga ketersediaan sumberdaya yang dibutuhkan hewan (makanan dan tempat untuk membuat sarang bagi hewan). 2) apakah mungkin dalam satu habitat terdapat dua spesies yang memiliki relung yang sama? Apabila terdapat dua hewan atau lebih mempunyai niche yang sama dalam satu habitat yang sama maka a...

The difference features of ectoterm and endoterm animal

Endotherms - regulate body temperature by internal heat production, (birds, mammals), Regulators - 35-40°C, Constancy of performance over wide range of temperatures, Large expenditure of energy to maintain internal heat (large food requirements) (cost), At higher temperature, they alter insulation, shunt blood flow to surface,  seek out cool habitats Ectotherms - depend on external heat sources, Depend on external heat sources, Conformers, Can moderate or modify heat exchange with environment by: Developing various body coverings (reflective), Simple or complex behaviors and Complex physiological process (be shivering). Changes in body temperature result in changes in rates at which physiological processes occur, Temperature coefficient = Q10 For every 10°C increase in temperature, a reaction rate (e.g., metabolism, development) increases two times Q10 = 2, May be higher or lower in some organisms for some reactions However, in mammals, not all the body is kept as a co...

analisis jurnal

Analisis jurnal Judul : kajian perubahan garis pantai menggunakan data satelit landsat di kabupaten kendal Oleh : muchlisin arif, gathot winarso, teguh prayogo ·         Analisis mengenai perubahan garis pantai dilakukan dengan analisis multi temporal menggunakan data satelit seri landsat (sensor MSS, TM, DAN ETM+) identifikasi garis pantai dilakukan dengan interpretasi visual pada RGB 542 dan kombinassi lainnya jika siperlukan ·         Perubahan terhadap garis pantai adalah proses tanpa henti (terus menerus) melalui berbagai proses baik pengikisan (abrasi) maupun penambahan (akresi). Di kabupaten kendal perubahan maju mundurnya garis pantai diperkirakan akibat proses penambahan areal tambak dan proses sedimentasi dari material yang dibawah oleh air sungai maupun ombak laut sedangkan abrasi diperkirakan akibat olehgempuran ombak atau erosi ·         Angin muson mengak...
