TL;DR: The use of DDT (an organochlorine insecticide) has been banned in Europe and North America and other industrialized nations, but in other parts of the world, it is intensively used as an insecticide to control vectors of diseases such as malaria, plague, typhus fever, yellow fever, sleeping sickness, and river blindness.
Abstract: The use of DDT (an organochlorine insecticide) has been banned in Europe and North America and other industrialized nations. However, in other parts of the world, it is intensively used as an insecticide to control vectors of diseases such as malaria, plague, typhus fever, yellow fever, sleeping sickness, and river blindness, and to control agricultural pests. It is also used in forestry management to control pests such as the spruce bud-worm and the Dutch Elm disease (Laws 1981). DDT is a very effective insecticide with a relatively low toxicity towards humans (Pine et al. 1980). Its use as an insecticide is still recommended by the Food and Agriculture Organization of the United Nations.

TL;DR: Findings indicate that damage to olfactory pathways is prominent in a rat model for domoic acid–induced chronic recurrent spontaneous seizures and aggressive behavior.
Abstract: The amnesic shellfish toxin, domoic acid, interferes with glutamatergic pathways leading to neuronal damage, most notably causing memory loss and seizures. In this study, the authors utilized a recently developed rat model for domoic acid–induced epilepsy, an emerging disease appearing in California sea lions weeks to months after poisoning, to identify structural damage that may lead to a permanent epileptic state. Sprague Dawley rats were kindled with several low hourly intraperitoneal doses of domoic acid until a state of status epilepticus (SE) appears. This kindling approach has previously been shown to induce a permanent state of epileptic disease in 96% animals within 6 months. Three animals were selected for neurohistology a week after the initial SE. An amino cupric silver staining method using neutral red counterstain was used on every eighth 40 mm coronal section from each brain to highlight neural degeneration from the olfactory bulb through the brain stem. The most extensive damage was found in the olfactory bulb and related olfactory pathways, including the anterior/medial olfactory cortices, endopiriform nucleus, and entorhinal cortex. These findings indicate that damage to olfactory pathways is prominent in a rat model for domoic acid–induced chronic recurrent spontaneous seizures and aggressive behavior.

TL;DR: The authors explored the development of an ecosystem services framework for mesophotic coral ecosystems (MCEs) in the context of those provided by shallow coral reefs and presented a baseline for further development as new data and information about MCEs become available.
Abstract: Accounting of the goods and services provided by ecosystems to human communities provides a basis for informed sustainable development, policy, and conservation decision-making. Coral reefs provide a myriad of such goods and services to coastal communities through direct provisioning (e.g., calories and natural products), environmental supporting and regulating services (e.g., nutrient or trophic cycling and stock support), and cultural products (e.g., tourism and culturally important ecosystems). Mid-depth coral communities (30–150 m), or mesophotic coral ecosystems (MCEs), are not generally addressed in ecosystem services accounting for coral reefs; however, they may share many of the services associated with shallow coral reefs, as well as provide unique ecosystem services of their own. The growing understanding that MCEs occupy large areas of previously uncharacterized insular and continental shelves suggests coral reef valuations need to account for these ecosystems. As shallower resources continue to decline due to anthropogenic pressures, it is crucial that we understand how MCEs support coastal ecosystems and human communities. Here, we explore the development of an ecosystem services framework for MCEs in the context of those provided by shallow coral reefs and present a baseline for further development as new data and information about MCEs become available. We recommend future research properly account for and valuate MCE ecosystem services, both individually and as they relate to ecosystem services for shallow-water reefs.

TL;DR: Light microscope observations of a haplosporidian in Diporeia spp.
Abstract: Light microscope observations of a haplosporidian in Diporeia spp. amphipods from Lakes Michigan and Huron, USA, found that the parasite spore is operculate and measures 8.1 microm in length and 6.1 microm in width. Round to amorphous sporocysts averaging 23.6 microm were present throughout hemal sinuses of infected amphipods. The number of developing spores within a sporocyst was highly variable and spores were observed in various stages of development. Electron microscopy revealed a lid over the operculum of developing spores and documented spores with fairly large and extensive ornamentation. This is the first haplosporidian reported in Diporeia spp. amphipods and only the second haplosporidian from freshwater species.
