Green leaves serve as the main photosynthetic structures of crop plants, containing the majority of chlorophyll, the functional traits of which directly affect photo-assimilate production and grain yield.
Sward composition and management play a major role in the quantity and quality of herbage grown on farms in temperate regions. While best practices for both livestock grazing and ensiled forage production are well documented in this regard, less is known about the optimum composition and management of swards used in frequent cutting systems.

Despite the knowledge of many marine ecosystems, there are still many untapped resources that could serve as a basis for the development of new products and new processes.
When discussing how we should design our future-food systems we need to consider feed-food competition occurring in our livestock systems. Feed-food competition occurs when arable land, which could be used to produce human edible food from crops, is instead used to produce feed for livestock.
Why would farmers in the Global North take time to work on plant breeding when they are busy farming with access to markets and can buy seed of modern varieties in catalogs? The authors of the paper, “Exploring the emergence of participatory plant breeding in countries of the global North - a review”, set out to answer that question and discovered much more.

More and more research is finding inflammation as a potential contributing factor towards to the development of various mental illnesses. A systematic review was conducted to determine the association between parasitic infection and mental illnesses in various African populations. Two parasite groups were evaluated; helminths and protozoans, and four mental illness classifications; depressive disorders, anxiety disorders, schizotypal disorders and unspecified mental illnesses.
Inspired by the DSA conference call for papers “Cartographies of Movement,” this digital collection showcases Dance Research Journal articles that engage with kinesthetic and epistemological sites of indigeneity. The three subdivisions narrate the general movement of peoples and ideas at sites of origin, across countries, and beyond geographic or imagined borders. Each article in the “Rooted in Indigeneity'' section addresses performance as a means of grounding specific Indigenous cultural beliefs.

Evolution has shaped women’s ovulatory cycles to be characterised by complex recurring physiological processes of changing hormones and organ tissue. However, these changes often bring about unwanted aspects – be it premenstrual symptoms such as mood swings, feeling bloated or anxious, menstrual pain, or – still way too often – menstrual shame.…
Global sea surface temperatures are rising and have hit record high values in recent months. This potentially threatens seabirds, their prey and their habitats, both on land and at sea.
Writing was refreshing to me because I was communicating again. However, I didn’t fully understand the extent until I watched Dead Poets Society, where the late Robin Williams delivered this moving monologue. He said, “We read and write poetry because we are members of the human race. And the human race is filled with passion. And medicine, law, business, engineering, these are noble pursuits and necessary to sustain life. But poetry, beauty, romance, love, these are what we stay alive for.”
