This study was carried out to better appreciate the sanitary situation of chicken grills sold near the streets of Korhogo town. First, a survey was conducted in sixty sale places of grill to describe the methods of preparation and storage of chicken grills. Then, the environment, equipment, raw material, method and workforce were observed in order to assess the hygiene of the preparation of these foods. After that, the microbiological quality of chicken grills was evaluated by looking for total aerobic mesophilic flora, faecal coliforms,S. aureusandSalmonella spp. Finally, the benzo[a]pyrene content in chicken grills was estimated through a cooking test. The survey revealed that the majority of sellers of chicken grills cooked the meat over an ember fire and stored the unsold grills cold in refrigerator or cooler. In most of the places of sale, the sellers did not comply with the principle of separating “clean” areas from “dirty” areas. Microbiological analysis showed that the overall quality of the chicken grills was unsatisfactory in most cases. The main microorganism responsible for the unsatisfactory quality of chicken grills was the total aerobic mesophilic flora (54.18 %). Moreover, the cooking test indicated that chicken meats cooked over an ember fire had a benzo[a]pyrene content above the maximum recommended limit (2 µg/kg). These results suggest that the chicken grills sold along the streets of Korhogo town are likely to represent a risk to consumer health. Therefore, sellers of chicken grills should be raised awareness and trained on good hygiene practices.

In Korhogo town, there is a proliferation of places selling grilled meats. Also, controlling contamination of meat by pathogenic germs and toxic compounds is a major challenge for actors in the sector. It is in this context that a study was conducted to assess the hygienic quality of mutton grills sold on the outskirts of the streets of Korhogo town. To do this, a survey was conducted among sellers to describe the preparation and storage methods of mutton grills. Then, at points of sale, observations were made on the environment, equipment, raw material, method and workforce in order to assess the hygiene of mutton grills preparation. After that, the microbiological quality of mutton grills was assessed by looking for TMAF, faecal coliforms, S. aureus and Salmonella spp. Finally, the benzo[a]pyrene (BaP) content in mutton grills was estimated through a cooking test. The survey revealed that the majority of mutton grills sellers (60%) cooked the meat over an ember fire and stored the unsold grills at room temperature in basins or baskets. In most of the sale places visited (83.33%), the sellers did not comply with the principle of separating “clean” and “dirty” areas. Microbiological analysis showed that unpackaged mutton grills had better microbiological quality compared to mutton grills packaged in recovery paper, which served as a cement bag. However, the mutton grills overall quality was unsatisfactory in most cases (66.67%). The main microorganisms incriminated in the unsatisfactory quality of mutton grills were S. aureus (53.67%) and faecal coliforms (51.67%). Furthermore, the cooking test indicated that mutton cooked over an ember fire had a BaP content above the recommended maximum limit (2 µg/kg). Considering the results above, the mutton grills sold on the outskirts of the streets of Korhogo town would present a risk of food toxi-infection and poisoning for consumers. These results must be taken into account in order to carry out preventive actions, such as

The use of environmental DNA (eDNA) for studying the ecology and variability of life in the sea is reviewed here in the context of US interagency Marine Biodiversity Observation Network (MBON) projects. Much of the information in this paper comes from samples collected within US National Marine Sanctuaries. The field of eDNA is relatively new but growing rapidly, and it has the potential to disrupt current paradigms developed on the basis of existing measurement methods. After a general review of the field, we provide specific examples of the type of information that eDNA provides regarding the changing distribution of life in the sea over space (horizontally and vertically) and time. We conclude that eDNA analyses yield results that are similar to those collected using traditional observation methods, are complementary to them, and because of the breadth of information provided, have the potential to improve conservation and management practices. Moreover, through technology development and standardization of methods, eDNA offers a means to scale biological observations globally to a level similar to those currently made for ocean physics and biogeochemistry. This scaling can ultimately result in a far better understanding of global marine biodiversity and contribute to better management and sustainable use of the world ocean. Improved information management systems that track methods and associated metadata, together with international coordination, will be needed to realize a global eDNA observation network.

Life in the sea provides immense benefits to humans, from the food we eat to the air we breathe to the climate we live in. And because of human activities, the once seemingly vast and inexhaustible seas are changing—increasingly threatened by global-scale impacts, such as warming and acidification, as well as those that are more localized, like overfishing and pollution. Meanwhile, many of the species that live in the sea remain unknown. Even for the known species, our understanding of their roles in the ecosystem is still limited. Now more than ever, increased observation of life in the sea is required to find and describe unknown species, observe shifts in species abundance and distribution, identify adaptability and resilience to climate change, and understand vital roles that species play in our marine systems. New and emerging technologies promise to enable observation over the required temporal and spatial scales. And emerging data systems will allow development of critical ecological understanding, while informing responsible use of marine natural resources. This will lead to continued, sustainable ecosystem services and the benefits we derive from them, benefits that are only possible through conserving biodiversity and managing human actions wisely.

Madagascar, a globally renowned biodiversity hotspot characterized by high rates of endemism, is one of the few remaining refugia for many plants and animal species. However, global climate change has greatly affected the natural ecosystem and endemic species living in Madagascar, and will likely continue to influence species distribution in the future. Madagascar is home to six endemic baobab (Adansonia spp., Bombacoideae [Malvaceae]) species (Adansonia grandidieri, A. suarezensis, A. madagascariensis, A. perrieri, A. rubrostipa, A. za), which are remarkable and endangered plants. This study aimed to model the current distribution of suitable habitat for each baobab species endemic to Madagascar and determine the effect that climate change will have on suitable baobab habitat by the years 2050 and 2070. The distribution was modeled using MaxEnt based on locality information of 245 occurrence sites of six species from both online database and our own field work. A total of seven climatic variables were used for the modeling process. The present distribution of all six Madagascar's baobabs was largely influenced by temperature-related factors. Although both expansion and contraction of suitable habitat are predicted for all species, loss of original suitable habitat is predicted to be extensive. For the most widespread Madagascar baobab, A. za, more than 40% of its original habitat is predicted to be lost because of climate change. Based on these findings, we recommend that areas predicted to contract in response to climate change should be designated key protection regions for baobab conservation.

Species and habitats are the subjects of legislation that mandates reporting of information on ecosystem conditions. Improvements in sensors, sampling platforms, information systems, and collaborations among experts and information users now enables more effective and up-to-date information to meet regional and national needs. Specifically, advances in environmental DNA (eDNA)-based assessments of biodiversity, community science data, various underwater imaging devices, and environmental, behavioral, and physiology observations from animal telemetry provide new opportunities to address multiple requirements for reporting status and trends, including insights into life in the deep ocean. Passive and active acoustic sensors help monitor marine life, boat traffic, and noise pollution. Satellites provide repeated, frequent, and long-term records of many relevant variables from global to local scales and, when combined with numerical computer simulations, allow planning for future scenarios. Metadata standards facilitate the transfer of data from machine to machine, thus streamlining assessments and forecasting and providing knowledge directly to the public. The Marine Biodiversity Observation Network (MBON) facilitates this exchange of information on life in the sea. The collaborative efforts of the Central and Northern California Ocean Observing System (CeNCOOS) of the US Integrated Ocean Observing System and its partners provide an example of a regional MBON process for information delivery. This includes linking policy and management needs, prioritizing observing data from various platforms and methods, streamlining data handling practices, and delivery of information for management such as for the Monterey Bay National Marine Sanctuary and the California Current Large Marine Ecosystem, with iterative process adaptation.

Medicinal plants are vital sources of easily accessible remedy used in the countryside healthcare system. This study aimed to find and make record of plants that are used for medicinal therapy by three communities living in Cherangani Hills. So far no single study has documented medicinal plants as a whole in the area. Ethnobotanical data were obtained through interviewing informants using semi-structured questionnaires and extracting information from journals and books. Descriptive statistical analysis was applied to describe the data. Overall 296 plant species from 80 families and 191 genera were identified. Asteraceae family was the most dominant, representing 10.7% of the total plant species recorded. Roots (35.9%) represented the most commonly used parts of the plant. The commonly used method of preparation was decoction (54.9%). The reported diseases were classified into 14 diverse ailment groups out of the 81 health conditions on their underlying user reports. Rural communities in Cherangani Hills are rich sources of plants with medicinal properties. Therapeutic uses of the compiled plants provide basic information that can aid scientists to conduct additional research dedicated to conservation of species and pharmacological studies of species with the greatest significance.
