“…One possible explanation is that the increase in isopods was due to an event that occurred in spring of that year which resulted in the uprooting of the only vegetation on this dead reef, a solitary black mangrove (Avicennia germinans) with numerous pneumatophores. The abundant benthic invertebrates in the 3-year samples from this dead reef were from the genus Sphaeroma, which contains many wood-boring species, some of which show preference for mangrove roots [68][69][70][71]. It is possible that the isopods were displaced from the roots into the sediment when the mangrove was uprooted.…”

In order to mitigate the degradation of eastern oyster (Crassostrea virginica) reefs in Mosquito Lagoon (ML) along the east coast of central Florida, oyster reef restoration efforts have been in place for over 14 years. These restored reefs are successful in terms of universal oyster metrics (i.e., density, shell height, reef height) and are similar to natural reefs. However, little is known about the impact of this restoration on bird populations. ML provides a habitat for many bird species, including several listed as “threatened” by the Florida Fish and Wildlife Conservation Commission. Many of these birds rely on oyster reefs for foraging and loafing habitats. As benthic invertebrates serve as an important food source for coastal birds, we monitored the abundances and diversity of these organisms on live, restored, and dead reefs. We collected sediment samples from the reef sites pre-restoration, and one month, six months, one year, two years, and three years post-restoration. We counted benthic invertebrates present in the sediment samples, and sorted them by taxa (polychaetes, amphipods, isopods, gastropods, bivalves, decapods). Benthic invertebrate abundances on restored reefs became similar to live reefs over time (species composition, density), indicating that the prey base on restored reefs was similar to that of live reefs within 6 months. A second objective of this study was to determine if restored oyster reefs reach the same abundances, foraging behaviors, and diversity of bird species on natural, live reefs. We conducted monthly bird surveys to assess bird utilization of live, restored, and dead reefs. After three years, the abundances, behaviors, and assemblages of birds on restored reefs were similar to live reefs.

“…However, some plant species in China, including Lumnitzera racemose Willd., Excoecaria agallocha L., and Ceriops tagal (Perr.) C.B.Rob., have been reported to be free from invasion even when grown in the habitat of this isopod (Xin et al 2020). In this study, we found that the invasion was not detected on S. ovata, which demonstrated that this species might be suitable to be planted in the Mahakam Delta or other areas with similar S. terebrans outbreaks.…”

Abstract. Harmonis, Haqiqi MT, Fahroni MFA, Jefry, Gunawan S, Sekedang MA, Rahmat D, Azhar NF, Putra MOPS, Kusuma FD, Hapsari MT, Muhammad FA, Diana R, Sudarmadji T, Amirta R, Ariyanto, Saud OR, Sofyan FPM, Fajriansyah, Asngari AMS, Bulo YS, Salman I, Rizaldi R, Lubis KM. 2024. Identification of the pest outbreak in the coastal mangrove ecosystem of Mahakam Delta, East Kalimantan, Indonesia. Biodiversitas 25: 829-835. Mangrove ecosystems are considered the most essential areas in the wetland since they sequester carbon more efficiently than terrestrial ecosystems. Thus, they have received significant attention as a nature-based solution to achieve the Naturally Determined Contributions in the commitment to global climate change mitigation. Currently, the degradation of mangroves has been linked to serious threats, including pest outbreaks. Our primary objective was to assess the pest outbreaks that occurred in the coastal mangroves of the Mahakam Delta, Indonesia. This study was conducted in two areas in Tanjung (R1 and R2) and one area in Pulau (R3). A total of 19 observation plots with a size of 10 × 10 m2 were made. The water quality was further measured to identify the natural conditions affecting the outbreaks. In the present study, it was found that significant disturbance of the mangrove plants occurred due to invasions by Amphibalanus amphitrite Darwin, 1854 and Sphaeroma terebrans Spence Bate, 1866. The dangerous attack from S. terebrans has only been found at the R1 site, where we found environmental conditions such as high dissolved oxygen (DO), high total dissolved solids (TDS), and high salinity. In this area, it could affect the death of adult Avicennia alba Blume and Sonneratia alba Sm. The results obtained from this study are expected to provide preliminary data to design the best management practices in order to enhance the effectiveness of the mangrove rehabilitation strategy in the Mahakam Delta.

“…Menurut beberapa laporan menyebutkan bahwa Sphaeroma sp. menjadi spesies invasif untuk vegetasi mangrove karena merusak dan memakan pohon mangrove sehingga sering ditemukan pohon mangrove yang tidak utuh (Xin et al, 2020;Thiri dan Yang, 2022). Dampak Sphaeroma sp.…”

Estuari Sungai Musi merupakan perairan semi tertutup yang dipengaruhi oleh dinamika pasang surut sehingga hanya beberapa biota khas yang mampu bertahan hidup di kawasan ini. Penelitian ini bertujuan untuk memahami tingkat biodiversitas kelompok gastropoda dan krustasea yang hidup pada zona intertidal estuari Sungai Musi. Pengambilan sampel dilakukan pada Bulan November 2021 di 5 titik stasiun pengamatan dengan metode transek kuadrat. Pengukuran kualitas perairan dilakukan meliputi suhu, pH, oksigen terlarut, dan salinitas. Hasil penelitian menunjukkan bahwa komposisi individu total krustasea (52%) dan gastropoda (48%). Kelimpahan total tertinggi hingga terendah secara berurutan ditemukan pada stasiun 4, 5, 2, 1, dan 3. Nilai indeks keanekaragaman berkategori sedang dengan nilai 1.30 – 1.76 nilai indeks keseragaman berkisar 0.48 – 0.65, nilai indeks dominansi 0.19 – 0.30. Berdasarkan hasil PCA menunjukkan bahwa F1 terdiri dari stasiun S1, S2, S4, dan S5 dengan variabel utama suhu, salinitas, DO, pH, keanekaragaman, keseragaman, dan dominansi sedangkan F2 terdiri dari stasiun S3 dengan kelimpahan. Berdasarkan hasil penelitian ini, zona intertidal menjadi habitat yang baik untuk kedua kelompok namun lokasi habitatnya cukup berpengaruh terhadap sebarannya secara spasial.
