Abstract:
Synergistic and antagonistic interactions in multi-species populations—such as resource sharing and competition—result in remarkably diverse behaviours in populations of interacting cells, such as in soil or human microbiomes, or clonal competition in cancer. The degree of inter- and intra-specific interaction can often be quantified through the notion of an ecological ‘niche’. Typically, weakly interacting species that occupy largely distinct niches result in stable mixed populations, while strong interactions and competition for the same niche result in rapid extinctions of some species and

Abstract:
Resolving how species compete and coexist within ecological communities represents a long-standing challenge in ecology. Research efforts have focused on two predominant mechanisms of species coexistence: complementarity and redundancy. But findings also support an alternative hypothesis that within-species variation may be critical for coexistence. Our study focuses on nine closely related and ecologically similar coral reef fish species to test the importance of individual- versus species-level traits in determining the size of dietary, foraging substrate, and behavioural interaction niches.

Abstract:
The microenvironment plays a crucial role in the behavior of stem and progenitor cells. In the heart, cardiac progenitor cells (CPCs) reside in specific niches, characterized by key components that are altered in response to a myocardial infarction. To date, there is a lack of knowledge on these niches and on the CPC interplay with the niche components. Insight into these complex interactions and into the influence of microenvironmental factors on CPCs can be used to promote the regenerative potential of these cells. In this review, we discuss cardiac resident progenitor cells and their regene

Abstract:
Intraspecific trait variation is an important determinant of fundamental ecological interactions. Many of these interactions are mediated by behaviour. Therefore, interindividual differences in behaviour should contribute to individual niche specialization. Comparable with variation in morphological traits, behavioural differentiation between individuals should limit similarity among competitors and thus act as a mechanism maintaining within-species variation in ecological niches and facilitating species coexistence. Here, we aimed to test whether interindividual differences in boldness covary

Abstract:
Competition plays a central role in the maintenance of biodiversity. A backbone of classic niche theory is that local coexistence of competitors is favoured by the contraction or divergence of species' niches. However, this effect should depend on the diversity of resources available in the local environment, particularly when resources vary in multiple ecological dimensions. Here, we investigated how available resource breadth (i.e. prey diversity) and competition together shape multidimensional niche variation (between and within individuals) and interspecific niche overlap in 42 populations

Abstract This conceptual paper re-evaluates the concept of niches in tourism markets. As many regions are now attempting to address niche markets in tourism as a development strategy, understanding of the dynamics of niche markets is crucial. Current approaches are often limited to seeing niche markets as simple subsectors of larger consumer markets. We argue for a broader view of market niches as forms of social rituals involving both consumers and producers with a mutual focus of attention. Based on the work of Randall Collins we examine how interaction rituals are produced and maintained, a

These species can compete with or prey on species of the recipient community, producing deep changes in the structure of these communities.

Abstract:
What is a niche? ‘Co-evolution and the formation of niches’ explains that the term ‘niche’ is widely used to describe an important part of the hierarchical organization of complex adaptive systems: local use of signals and resources. Using Markov processes, a mathematical theory of niches can be formed that allows for multiple species with interaction networks that involve loops and recirculation. When realistic niches are considered, the diversity of the niche dwellers stands out. We see a complicated recirculation of resources and signals. How did this complex network of interactions evolve?

The metabolism and physiology of an invading fungal pathogen determine the outcome of its interaction with the host. The pathogen must be able to assimilate nutrients to grow and colonize diverse host niches. Meanwhile, the host attempts to restrict this growth by withholding some essential nutrients, by imposing stresses, and by inducing innate immune defences. These interactions involve complex regulatory networks that ultimately dictate the equilibrium between pathogen killing and the establishment of commensal or pathogenic associations.

The position of ASEAN “neutrality” and Japan’s “pacifism” reduce its potential in regional security issues but create a niche for cooperation to support Pacific states in the context of regional challenges.

Abstract:
In normal cells, mechanisms that prevent the development of cancer function, while in tumor cells there are defects in the regulatory chain that controls cell proliferation and its homeostasis. Intercellular communication is the exchange of information through various signaling mechanisms affecting many aspects of cell life and is crucial for morphogenesis, differentiation, interaction, homeostasis and cell growth. The study of the mechanisms of intercellular communication mediated by extracellular vesicles is important for understanding the sequential events in the cell that lead to the devel

Abstract:
Carbon Capture and Storage (CCS) is a recognized technology pathway to curb the increasing emissions of carbon dioxide (CO2) from the power generation sector. But most available technologies are still on the study or laboratory-scale level, so that considerable R&amp;D efforts are needed to achieve commercialization level. The Graz Cycle originally presented in 1995 by Jericha [1] is an oxyfuel technology and promises highest efficiency using state-of-the-art turbine materials and improved thermodynamic developments in a comparatively complex interaction of rotating machinery, condensers and h

Abstract:
The Opportunities for the Majority Initiative (OMJ) was originally set up for three years as a time-bound pilot initiative. The OMJ team has worked diligently to test the Base of the Pyramid model and develop the OMJ portfolio, and from that standpoint the initiative has been successful. Regarding OMJ's operational objectives, its achievements on targeting, innovation, learning, and replication have been mixed. OMJ has not found a unique market niche that cannot be served by another IDB Group private sector window with significant operational advantages over OMJ. In light of the findings, the

Mastitis, an inflammatory response of the mammary tissue to invading pathogenic bacteria, is the largest health problem in the dairy industry and is responsible for multibillion dollar economic losses. E. coli are a leading cause of acute mastitis in dairy animals worldwide and certainly in Israel and North America. The species E. coli comprises a highly heterogeneous group of pathogens, some of which are commensal residents of the gut, infecting the mammary gland after contamination of the teat skin from the environment.

Over the last few decades, the organic agriculture sector has experienced sustained growth. Globally, as well as in the European Union and Portugal, organic production accounts for just under 10% of total Utilised Agricultural Area (UAA) (FiBL, 2019; Eurostat, 2019; DGADR, 2019; INE, 2019; GPP, 2019). This growth has been seen in terms of production, number of producers, amount of retail sales, imports and exports.

Abstract:
Until recently, environmental pH was not considered a factor in determining pathogen compatibility. Our hypothesis was that the environmental pH at the infection site, which is dynamically controlled by activities of both the host and the pathogen, regulates the expression of genes necessary for disease development in Colletotrichum gloeosporioides and Sclerotinia sclerotiorum. This form of regulation ensures that genes are expressed at optimal conditions for their encoded activities.Pectate lyase encoded by pelB, has been demonstrated to play a key role in virulence of C. gloeosporioides in a
