“…Indeks keanekaragaman pada perairan pulau panjang rata-rata tergolong rendah diduga karena adanya spesies yang mendominasi pada perairan tersebut. Hal tersebut diperkuat oleh Avila et al (2020) yang menyatakan bahwa sekelompok Nudibranchia adalah bagian dari kumpulan makrofauna yang berkaitan dengan spons tempat tinggalnya. Kepadatan tinggi pada satu spesies dapat berperan dalam mengatur populasi mangsa spons mereka dan memengaruhi distribusi spasial.…”

Nudibranchia merupakan salah satu gastropoda laut yang masuk kedalam anggota Subkelas Opisthobranchia. Ciri Nudibranchia yang menjadi perbedaan dari gastropoda lainnya yaitu adanya insang telanjang. Penelitian ini dilaksanakan pada September 2020 di Pulau Panjang, Kabupaten Jepara, dengan tujuan untuk mengetahui jenis dan kelimpahan Nudibranchia serta mengetahui hubungan antara bahan organik sedimen dengan kelimpahan Nudibranchia. Metode yang digunakan dalam penelitian ini yaitu metode observasi, sedangkan metode yang diterapkan pada saat pengamatan di lapangan yaitu metode Belt Transect dengan mengamati 5 stasiun, tiap stasiun terdiri dari 3 line transect dengan sekali sampling pada tiap line transect, pengamatan selebar 2 meter kanan dan kiri dengan panjang 25 meter pada tiap line transect. Identifikasi Nudibranchia menggunakan buku 1001 Nudibranchias Catalogue Of Indo-Pacific Sea Slug dan World Register of Marine Species. Indeks Ekologi yang dianalisis meliputi kelimpahan, indeks keanekaragaman, indeks keseragaman, indeks dominansi. Nudibranchia yang ditemukan di perairan Pulau Panjang sebanyak 3 spesies yaitu Jorunna funebris, Chromodoris lineolata dan Phyllidiella nigra. Kelimpahan tertinggi berada pada stasiun 5 yaitu dengan nilai 63 ind/300m2 dan kelimpahan terendah terdapat pada stasiun 3 yaitu dengan nilai 5 ind/300m2. Keanekaragaman Nudibranchia di perairan Pulau Panjang cenderung rendah karena hanya stasiun 3 yang memiliki kategori keanekaragaman sedang dengan nilai 1,427. Kandungan bahan organik sedimen pada perairan Pulau Panjang cukup tinggi yaitu 63,5%. Kelimpahan Nudibranchia dengan bahan organik sedimen memiliki hubungan sangat kuat dengan nilai koefisien korelasi sebesar 0,935.

Sponges are one of the most conspicuous groups of epibionts in mangrove prop root habitats. However, with the exception of the Caribbean and the Indo-Pacific regions, studies focused on species diversity are lacking in other locations that have high mangrove coverage and are relatively distant from coral reef environments. Because mangrove-root epibiont communities, in general, have been understudied worldwide, this research contributes to filling this knowledge gap. In this study, a total of 30 sponge species (belonging to three subclasses, 14 families and 19 genera) were recorded as epibionts on prop roots of the red mangrove Rhizophora mangle in a tropical coastal ecosystem of the Southern Gulf of Mexico. Of these, five were new records for the Gulf of Mexico, 14 were new for the Mexican coasts of the gulf and 25 were new for the study area. Moreover, a similarity analysis based on presence/absence data of mangrove-associated sponges reported throughout the Western Central Atlantic region revealed that the sponge assemblage from the study area was more similar to those documented in most of the Caribbean locations (Jamaica, Cuba, Martinique, Panama, Venezuela, Belize and Colombia) rather than with those of the Northeast of the Gulf of Mexico, Guadeloupe and Trinidad. This relative intra-regional dissimilarity in the structure of mangrove-associated sponge assemblages may be related to differences in environmental conditions as well as taxonomic effort. The study area, unlike most of the Caribbean locations, is characterized by estuarine conditions and high productivity throughout the year. The inter-site variability recorded in the composition of mangrove-associated sponges was influenced by a set of factors such as salinity, dissolved oxygen and hydrodynamism. This study shows the importance of exploring the mangrove-associated sponge assemblages from different regions of the world as it furthers knowledge of the biodiversity and global distribution of this group.
