Summary: In recent decades, sustainable forest resource management through state-community collaboration has become the focus of resource management discussions. In Ghana, forest reserves are declining due to poaching and encroachment by fringe communities. This study aims to fill the literature gap by examining the dynamics of community-state collaboration in forest resource management in the Mole National Park. The study finds that power manipulation, limited community engagement, placation, and a centralized approach to park management are issues affecting the management and sustainability of the park. The study recommends collaborative management and equity in resource benefit sharing for sustainable forest resource management.

Summary: Community-based conservation is widely adopted, but there is still uncertainty about its success under different conditions. The heterogeneity of wealth and risk within participating communities, due to differences in livestock/agricultural holdings and exposure to wildlife depredation, has not been thoroughly studied. This knowledge gap limits policymakers' ability to design effective community-based programs.

Summary: Efforts to promote community-based natural resource management (CBNRM) in Namibia have yielded mixed results, with positive impacts on wildlife conservation but negative effects on woodland cover. The study suggests that CBNRM works well for woodland conservation when communities are located near wildlife corridors, providing opportunities for tourism income. Complementary conservation incentives may be necessary to make Namibia's CBNRM model suitable for participation in REDD+.

Summary: Worldwide, marginalized and low-income communities will suffer the most from climate change impacts but have the least power to mitigate them. Scientists have long been providing policy recommendations that aim to balance humanitarian needs with the conservation of ecosystems and wildlife. However, many conservation and development practitioners lack training in social research and participatory project design, which can lead to failed initiatives, even with community support.

Summary: Iron and phosphorus are identified as major nutrients limiting marine nitrogen fixation. The study revealed regionally distinct distribution patterns of diazotrophic phylotypes and demonstrated that nitrogen fixation in the Pacific Ocean is limited by iron and phosphorus individually as well as colimitation by both nutrients in the western North Pacific subtropical gyre. The response of nitrogen fixation to environmental changes varies among different regions.

Summary: The study analyzed the distribution and abundance of holothurians in relation to types of bottom sediment and biomes in inner reefs of Ishigaki Island, Japan, before the boom of fisheries in the 1990s. The dominant species, such as H. atra and St. chloronotus, were found to be abundant in specific bottom sediment. The findings also indicated seasonal fluctuations in the density of H. atra and a slow growth rate, suggesting a reached carrying capacity in the population.

Summary: This study tested the applicability of wild juvenile collection (WJC) for tropical sea cucumbers. Coconut fibre and mesh bags were found to be more suitable materials for settling larvae compared to oyster shells. A simple collector design using coconut fibre was successful in collecting various species of tropical holothurians. The results demonstrate the potential of WJC as a viable option for restocking and conservation of endangered holothurian resources.

Summary: The artificial rearing techniques of Actinopyga lecanora larvae and juveniles were developed for the first time. The induction of spawning was successfully achieved by injecting an artificially-synthesized relaxin peptide into mature individuals. The larvae went through several developmental stages and eventually settled as pentactula. The lecithotrophic nature of the larvae offers potential for low-cost seed production.

Summary: This study demonstrates that adding taxonomically verified sequences to the public database improves the accuracy of species identification through metabarcoding analysis. The newly registered sequences, mainly composed of small non-calanoid copepods, increased the number of OTUs associated with a single species and had higher similarity values than the pre-existing sequences. Continuous registration of sequence data is necessary for further improvement of zooplankton monitoring using metabarcoding analysis.

Summary: This study investigated the population dynamics of the snake sea cucumber in a seagrass meadow on the southern coast of the Red Sea in Saudi Arabia. The results showed a drastic decline in the abundance of the sea cucumber after the die-off of the seagrass meadow. Correlation analysis revealed significant positive relationships between the abundance of the sea cucumber and dissolved oxygen, wind speed, and barometric pressure, while salinity, water temperature, and air temperature showed significant negative relationships. The study suggests that the population dynamics of the sea cucumber are influenced by extreme abiotic environmental factors and the presence of seagrass meadows.
