Diversity 2 Map 1.8.8

Return to the world of Diversity – an epic multi-genre challenge map for single or multiplayer! PC Gamer’s #2 Minecraft Map of all time has spawned a sequel. Now with over 2 million downloads, Diversity 2 has quickly become Curse.com’s #1 most downloaded map, overcoming the original Diversity map as well as achieving the Guinness World Record for most downloaded Minecraft project. Diversity 2 is a unique form of map. Similar to the CTM style, you are tasked to complete a monument. However, in the Diversity series, the monument blocks are obtained from completing different genre-specific levels.

This time, a team of builders were enlisted and the end product is really quite special. We hope you enjoy the map. Diversity 2 also proudly features custom skins from over 650 members of the Minecraft community!


What is Biodiversity?

Biology is the study of all living organisms (plants, animals, microorganisms) and how they interact with each other and their environment. It examines the structure, classification, function, growth, origin, evolution, and distribution of all living things.

Biodiversity, abbreviated from the terms 'biological' and 'diversity', encompasses the variety of lifeforms found at all scales of biological organisation, ranging from genes to species to ecosystems. The greatest biodiversity is found in the tropical regions of the world, particularly among tropical rainforests and coral reefs. Biodiversity is increased by genetic change and evolutionary processes and reduced by habitat destruction, population decline and extinction. There is a growing recognition that the level of biodiversity is an important factor in influencing the resilience of ecosystems to disturbance.

Biodiversity is a complex term that includes not only the variety of different animals (species diversity) but also the difference between animals of the same species (genetic diversity) and between ecosystems (ecosystem diversity).

Genetic Diversity is the diversity of genetic characteristics (expressed or recessive) within a species (i.e. between individuals and populations of the same species). This component of biodiversity is important because it allows populations to adapt to environmental changes through the survival and reproduction of individuals within a population that have particular genetic characteristics that enable them to withstand these changes. The maintenance of high genetic diversity within populations is therefore a conservation and management priority as this provides the greatest capacity for any population to adapt to a broad range of environmental changes. Conversely, failure to maintain genetic diversity limits the capacity for a population to adapt, making it vulnerable to even small changes in the environment and increasing the likelihood of extinction.

Species Diversity is simply the number and relative abundance of species found in a given biological organisation (population, ecosystem, Earth). Species are the basic units of biological classification and hence, this is the measure most commonly associated with the term 'biodiversity'. Worldwide, about 1.75 million different species have been identified. However, many environments and groups of organisms are not well studied and estimates of species numbers range from 3 to 100 million. Diversity in species is important for economic, biological, social and cultural reasons. Major threats to species diversity are loss of habitat and fragmentation, over exploitations (fishing, hunting, extraction), pollution, the introduction of invasive species (e.g Asian Green Mussels) and global climate change. In order to conserve species diversity, natural resource management and habitat protection are vital.

Ecosystem Diversity can be defined as the variety of different habitats, communities and ecological processes. A biological community is defined by the species that occupy a particular area and the interactions between those species. A biological community together with its associated physical environment is termed an ecosystem.

Partly due to its complexity, biodiversity can be extremely difficult to measure. However, there are a few key indicators of biodiversity that we can accurately and efficiently monitor. For coral reefs these indicators include: seafloor diversity, seagrass, mangroves, seabirds, species of conservation concern and species richness and community structure of hard corals on the GBR.

Review of the diversity, traits, and ecology of zooxanthellate jellyfishes

Many marine organisms form photosymbioses with zooxanthellae, but some, such as the medusozoans, are less well known. Here, we summarize the current knowledge on the diversity of zooxanthellate jellyfishes, to identify key traits of the holobionts, and to examine the impact of these traits on their ecology. Photosymbiosis with zooxanthellae originated at least seven times independently in Medusozoa of these, five involve taxa with medusae. While most zooxanthellate jellyfishes are found in clades containing mainly non-zooxanthellate members, the sub-order Kolpophorae (Scyphozoa: Rhizostomeae) is comprised—bar a few intriguing exceptions—of only zooxanthellate jellyfishes. We estimate that 20–25% of Scyphozoa species are zooxanthellate (facultative symbiotic species included). Zooxanthellae play a key role in scyphozoan life-cycle and nutrition although substantial variation is observed during ontogeny, or at the intra- and inter-specific levels. Nonetheless, three key traits of zooxanthellate jellyfishes can be identified: (1) zooxanthellate medusae, as holobionts, are generally mixotrophic, deriving their nutrition both from predation and photosynthesis (2) zooxanthellate polyps, although capable of hosting zooxanthellae rarely depend on them and (3) zooxanthellae play a key role in the life-cycle of the jellyfish by allowing or facilitating strobilation. We discuss how these traits might help to explain some aspects of the ecology of zooxanthellate jellyfishes—notably their generally low ability to outbreak, and their reaction to temperature stress or to eutrophication—and how they could in turn impact marine ecosystem functioning.

Species-diversity and pattern-diversity in the study of ecological succession

A measurable property of any collection of organisms containing more than one species is its “species-diversity”. Methods of measuring species-diversity based on the information content of a collection are reviewed. A collection consisting of a community of sessile organisms, such as terrestrial plants, also has “pattern-diversity”. The pattern-diversity of a community is high when the individuals of the various species are thoroughly mingled so that several species are usually present in any small sub-area it is low if the species are segregated so that small sub-areas are likely to contain individuals of only a few of the species. A method of measuring pattern-diversity is proposed.

The changes that occurred in both species- and pattern-diversity, during periods of five or ten years, in young dense communities of forest trees were observed. It was found that the natural thinning resulting from competition among the trees caused an increase in pattern-diversity.

A census of pathway maps in cancer systems biology

A key goal of cancer systems biology is to use big data to elucidate the molecular networks by which cancer develops. However, to date there has been no systematic evaluation of how far these efforts have progressed. In this Analysis, we survey six major systems biology approaches for mapping and modelling cancer pathways with attention to how well their resulting network maps cover and enhance current knowledge. Our sample of 2,070 systems biology maps captures all literature-curated cancer pathways with significant enrichment, although the strong tendency is for these maps to recover isolated mechanisms rather than entire integrated processes. Systems biology maps also identify previously underappreciated functions, such as a potential role for human papillomavirus-induced chromosomal alterations in ovarian tumorigenesis, and they add new genes to known cancer pathways, such as those related to metabolism, Hippo signalling and immunity. Notably, we find that many cancer networks have been provided only in journal figures and not for programmatic access, underscoring the need to deposit network maps in community databases to ensure they can be readily accessed. Finally, few of these findings have yet been clinically translated, leaving ample opportunity for future translational studies. Periodic surveys of cancer pathway maps, such as the one reported here, are critical to assess progress in the field and identify underserved areas of methodology and cancer biology.
