Beach flora along the maritime ecosystem is very sensitive and fragile in nature. Studies on floral species composition and their ecological role in the sensitive coastal and marine ecosystem of Indian coast in general and coast of Odisha in particular are scanty. Keeping in view, a detailed survey along the coast of Gahirmatha beach in Kendrapara district, Odisha was conducted. A total of 67 species under 62 genera belonging to 36 families of flowering plants were collected and identified at different localities from the shoreline towards inland of the coastline. The floral composition of sandy beach of Gahirmatha coast was found to be rich and diverse. The sensitive ecosystem need to be protected from habitat degradation in order to provide congenial niche for the diverse beach elements that caters the ecological functioning and also supporting the associated floral as well as faunal assemblages in the area.

The incidence of emerging infectious diseases (EIDs) has increased in wildlife populations in recent years and is expected to continue to increase with global change. Marine diseases in particular are relatively understudied compared to terrestrial disease, but they can disrupt ecosystem resilience, cause economic loss, or threaten human health. While there are many existing tools to combat the direct and indirect consequences of EIDs, these management strategies are often insufficient or ineffective in marine habitats compared to their terrestrial counterparts, often due to fundamental differences in marine and terrestrial systems. Here, we first illustrate how the marine environment and marine organism life history present challenges or opportunities for wildlife disease management. We then assess the application of common disease management strategies to marine versus terrestrial systems to identify those that may be most effective for marine disease outbreak prevention, response, and recovery. Finally, we recommend multiple actions that will enable more successful management of marine wildlife disease emergencies in the future. These include prioritizing marine disease research and understanding its links to climate change, preventatively increasing marine ecosystem health, forming better monitoring and response networks, developing marine veterinary medicine programs, and enacting policy that addresses marine and other wildlife disease. Overall, we encourage a more proactive rather than reactive approach to marine conservation in general and to marine wildlife disease in particular and emphasize that multi-disciplinary collaborations are key to managing marine wildlife health.

Biological traits analysis (BTA) is considered to be a powerful technique for describing the ecological functioning of marine benthic assemblages. This study is the first to apply BTA to assess differences in the traits of benthic faunal assemblages between areas exposed to heavy and light trawling in a major upwelling ecosystem along the west coast of southern Africa. The data were collected from two sampling locations in Namibia and six sampling locations in South Africa. The intensity of trawling varied from area to area. Significant differences in biological traits (BT) were detected between heavily and lightly trawled areas. Weighted infaunal traits showed significant differences between heavily and lightly trawled areas for 17% of the traits investigated, while 24% of epifaunal traits investigated were significantly different between areas of different trawling intensities. This suggests that the measured BTs of the epifauna might be more sensitive to trawling disturbances than BTs of the infauna. The infaunal traits differed significantly between areas with larger or smaller proportions of sand and mud. Nevertheless, more of the significant differences in infaunal BTs were related to variations in trawling intensity than to variations in sediment composition. Significant modifications of BTs are likely to lead to modified functioning of the community and provide more general potential indicators for management than those based on species. The study confirms the need for more basic biological and life history data on macro-benthic invertebrates but nevertheless shows that BTA detected specific features that correlate with trawling intensity and that these features may be important for epifaunal assemblage functioning.

Kelp forests define >8000km of temperate coastline across southern Australia, where ~70% of Australians live, work and recreate. Despite this, public and political awareness of the scale and significance of this marine ecosystem is low, and research investment miniscule (<10%), relative to comparable ecosystems. The absence of an identity for Australia’s temperate reefs as an entity has probably contributed to the current lack of appreciation of this system, which is at odds with its profound ecological, social and economic importance. We define the ‘Great Southern Reef’ (GSR) as Australia’s spatially connected temperate reef system. The GSR covers ~71000km2 and represents a global biodiversity hotspot across at least nine phyla. GSR-related fishing and tourism generates at least AU$10 billion year–1, and in this context the GSR is a significant natural asset for Australia and globally. Maintaining the health and ecological functioning of the GSR is critical to the continued sustainability of human livelihoods and wellbeing derived from it. By recognising the GSR as an entity we seek to boost awareness, and take steps towards negotiating the difficult challenges the GSR faces in a future of unprecedented coastal population growth and global change.

A faunistic survey was made to assess the tiger beetle fauna from the Chakrashila Wildlife Sanctuary and adjacent rivers for the first time from the western part of Assam, India.  A total of 15 species of tiger beetles (subfamily Cicindelinae) belonging to seven genera were recorded from forest, moist and dry riverine ecosystem using an occasional night trap.  Eight species belonging to five genera were recorded from the riverine ecosystem.  Two species, viz., Cylindera spinolae and Calochroa assamensis, were strictly restricted to the forest and Cosmodela virgula was recorded from both forest and riverine areas.  Cylindera (Eugrapha) minuta, Calochroa flavomaculata, and Lophyra (Spilodia) vittigera were collected using a night trap from the forest area.  The study revealed that habitat degradation due to human interference is the major threat to the tiger beetles in the study area.

Abstract Globalization has led to massive rise in cross border trade. Increase in E-commerce business has contributed to this too. As a result, a continuous and complex logistics network of supply chains operate across the globe round the clock. Transportation of goods is the most essential activity of this network. Statistics reveals that approximately 90 percent of world’s goods are transported via sea route. This intense network of shipment poses a huge threat to marine ecosystem in numerous ways. One of the most dangerous events for marine ecosystem is oil spill. Oil spill from vessels and pipelines are a major reason behind mortality of marine wildlife. The present work focuses on developing a cost-effective sustainable solution for mitigation of marine oil spill. It was found from existing literature that peels of some fruits have substantial oil absorbing capacity. This fact was experimentally validated and a reduced scale prototype was designed aiming for the task of deployment in case of oil spill in marine waters. The experimental results show that the proposed model floats on water after absorbing oil up to its saturation value. It was also found that through appropriate mechanical setup, absorbed oil can be extracted for reuse or processing.
