Diversity and Ecosystem Function

Floristic Composition, Structure and Soil Properties of Mixed Deciduous Forest and Deciduous Dipterocarp Forest: Case Study in Madan Watershed, Myanmar

“…This may include the number of species present, but often takes into account quantitative measures such as abundance, frequency, density, coverage, and basal area [3]. Measures of diversity such as the Shannon and Simpson indices have also been useful for specifying and comparing forest communities [4]. Soils are important to life on earth and the quality of the soil determines the nature of plant ecosystems and the capacity of land to support animal life and society [5].…”

Recent Landscape Changes on a Small Mediterranean Island

“…According to Leps (2005), "plant establishment from seed is a highly improbable event: often, only one of many thousands or millions of seeds becomes established". Successful establishment will be more improbable still in a case of an isolated area such as an island, and especially if the hypothetical 'climax species' (in our case Quercus ilex) is usually spread by a bird such as the Eurasian jay (Garrulus glandarius, see Gómez, 2003) that is reported as being absent, or at best sporadic (P. Sposimo, personal communication) for this island.…”

“…The species diversity of a site is determined by two factors: 1) the biotic and abiotic conditions and their interaction (Zobel, 1992) and 2) the set of propagules which are able to arrive at a site (Leps, 2005, van der Maarel, 2005. According to Leps (2005), "plant establishment from seed is a highly improbable event: often, only one of many thousands or millions of seeds becomes established".…”

Karakteristik Vegetasi Habitat Orangutan (Pongo pygmaeus morio) di Hutan Tepi Sungai Menamang, Kalimantan Timur

“…Rendahnya indeks tersebut dipengaruhi oleh lokasi hutan yang berdampingan dengan perkebunan kelapa sawit sehingga sumber benih hanya berasal dari pohon induk yang terdapat di dalam hutan. Secara umum, tingkat keanekaragaman jenis yang termasuk kategori sedang sampai tinggi mengindikasikan bahwa vegetasi tepi sungai Menamang memiliki tingkat resistensi dan resiliensi yang cukup baik jika terjadi gangguan (Lepš, 2013). Selain itu, mengingat hutan tepi Sungai Menamang merupakan salah satu habitat penting bagi orangutan pada lanskap yang telah terdegradasi (Meijaard et al, 2010), tingkat keanekaragaman jenis dengan kategori tersebut menunjukkan bahwa lokasi penelitian diduga mampu mendukung kebutuhan hidup orangutan seperti pakan, namun penelitian lebih lanjut mengenai aspek tersebut perlu dilakukan.…”
