Abstract

Fluctuation of water regimes where plant grows has been known to affect the plant chemical, nutrition compositions and plant chemical defenses, which can affect the vulnerability of plants to insect herbivores. This research aimed to compare the concentration of plant nutrition and chemical defenses of Melaleuca ercifolia grows on different water regimes, subsequently to insect herbivore attacks. The leaf total nitrogen was higher in plants growing in water fluctuated areas, therefore the insect herbivores compared to plants growing in prolong-flooded condition. Insect herbivores prefer to consume plants that are more nutritious and less affected by the plant growing conditions.

Abstract

Pantai Mengiat Nusa Dua, Bali merupakan salah satu pantai yang memiliki ekosistem padang lamun dengan keanekaragaman makrozoobenthos yang melimpah. Padang lamun (Seagrass) merupakan tumbuhan tingkat tinggi dan berbunga (Angiospermae) yang hidup terendam pada dasar perairan laut dangkal. Salah satu kelompok biota laut yang sering dijumpai pada kawasan padang lamun adalah jenis makrozoobenthos. Penelitian ini dilaksanakan pada bulan Januari - Maret 2021. Tujuan penelitian ini adalah untuk mengetahui kerapatan ekosistem lamun, kelimpahan makrozoobenthos serta hubungan kerapatan lamun dengan kelimpahan makrozoobenthos di Perairan Pantai Mengiat Nusa Dua, Bali. Sampel lamun dan makrozoobenthos diambil menggunakan transek kuadrat berukuran 0,5 x 0,5 m dengan 30 titik pada 3 stasiun dengan jarak 20 m antar titik. Spesies lamun yang ditemukan di Pantai Mengiat membentuk vegetasi campuran dengan 7 spesies lamun dengan kerapatan jenis tertinggi ditemukan pada Cymodocea rotundata. Makrozoobenthos yang ditemukan pada penelitian ini meliputi 1 spesies dari Kelas Bivalvia dan 14 spesies dari Kelas Gastropoda. Hubungan kerapatan lamun dengan kelimpahan makrozoobenthos menunjukkan hubungan yang kuat dengan nilai korelasi -0,765 dan menunjukkan arah negatif (-), dimana semakin tinggi nilai kerapatan lamun maka kelimpahan makrozoobenthos akan semakin rendah.

Abstract

Gerris marginatus is one fresh water insect distributed from temperate to tropicalareas. It can be found in almost every freshwater biotope, making them excellent objects forecological and biogeographic studies.  Most recent studies found that this water insect wasone good candidate for examining the effect of fresh water pollution.  This species showsmorphometric differences between male and female, but there has no studies examining thismorphometric differences particularly in tropical areas.  This study aimed to determine andinvestigate the morphometric differences between male and female and their sex ratio of G.marginatus in one of freshwater body in Bali.   Samples were collected from Jangu River atKarangasem Regency on February 2014.  Samples were preserved in 70 % awaiting foridentification and further studies. Identification was performed at Animal TaxonomyLaboratory, Biology Department. The results show that there were morphometric differencesbetween male and female of G. marginatus in tropical area.  Males were significantly largerof many variable measured compared to females. However, they also exhibit sex ratio biastoward females.

Abstract

Mangrove ecosystems are able to support biological and ecological life cycles and provide welfare for coastal communities. Pest outbreaks that attack seedlings to mangrove trees often cause ecological losses throughout the TAHURA Ngurah Rai Bali area. The ecological interactions of barnacle pest species in mangrove ecosystems are very complex and highly detailed studies. There is empirical evidence that the attachment of barnacles is strongly associated with allelochemical compounds produced by mangroves. This study aims to inventory the attachment of barnacles (arthropods) to several types of mangroves in the TAHURA Ngurah Rai area of Bali. This study used a purposive sampling method to pay for the location of the observations. Quadrant transects were used to organize the classification of the mangrove plots, barnacle densities being calculated for each transect. The density of barnacles was calculated on the number of barnacles attached to the mangrove plants, then recorded the types of plants attached, types of barnacles, types of planting and the number of individuals for each mangrove classification. The study showed that barnacles planted most of the mangrove seedlings at all stations, while the classification of tree plots only had barnacles attached at station 3. The number of attachments of Amphibalanus sp. the highest was found at station 3 of the R. mucronata tiller classification of 881 individuals, while no attachment of barnacles was found at all stations for S. alba mangroves. Overall, the attachment of barnacles was higher in R. mucronata tillers and had the potential to reduce their growth productivity in the field. Efforts to control barnacles really need to be done to increase the success of planting mangroves in TAHURA Ngurah Rai, Bali.
