The Ocean Biodiversity Information System (OBIS) is a global, collaborative initiative aimed at providing access to data on marine biodiversity. It serves as a platform for aggregating, integrating, and disseminating data related to the distribution of marine species and their associated habitats. OBIS is a part of the International Oceanographic Data and Information Exchange (IODE) of the Intergovernmental Oceanographic Commission (IOC), which is a part of UNESCO.
The Nunatak Hypothesis is a concept in glaciology and paleogeography that seeks to explain the distribution of certain species, particularly plants and animals, during periods of glaciation. According to this hypothesis, during ice ages, some areas of land, known as nunataks, were not completely covered by ice. These nunataks acted as refuges or safe havens for various species, allowing them to survive when surrounding areas were glaciated.
"Northern Provinces" can refer to different regions depending on the context. Here are a few possible interpretations: 1. **South Africa**: Historically, the term "Northern Provinces" was used to refer to the provinces in the northern part of South Africa, specifically the provinces of Limpopo, Mpumalanga, and parts of Gauteng. However, the term is less commonly used in contemporary discussions, as South Africa's provinces have undergone changes and rebranding since the end of apartheid.
"Northern Highlands" can refer to several different concepts or places, depending on the context: 1. **Geographic Region**: In a geographic context, "Northern Highlands" typically refers to elevated areas in the northern part of a country or region. For instance, in Scotland, the term could refer to the northern part of the Highlands, known for its rugged landscapes, mountains, and cultural heritage.
Zealandia, sometimes referred to as Neozealandia, is a submerged continent that is mostly underwater, with only a small portion—primarily New Zealand and some surrounding islands—exposed above sea level. It is estimated to cover an area of about 4.9 million square kilometers (1.9 million square miles), making it one of the largest known submerged landmasses.
The Neotropical realm is one of the major biogeographic regions of the world, encompassing a vast area of the Americas, including much of South America, Central America, and the Caribbean. It is characterized by a rich diversity of flora and fauna, many of which are unique to the region due to its varied ecosystems, such as tropical rainforests, savannas, deserts, and mountainous areas.
Native species are organisms, including plants, animals, fungi, and microorganisms, that originate and naturally occur in a specific geographical area or ecosystem. These species have evolved to thrive in their environment and have established relationships with other species and the habitat in which they live. Key characteristics of native species include: 1. **Evolutionary History**: Native species have adapted to the local climate, soil, and conditions over many generations.
Microbial biogeography is the study of the distribution of microbial populations and communities across different geographical areas and environmental gradients. It aims to understand how various factors, including environmental conditions, geological features, climate, and human activities, influence the diversity, composition, and abundance of microbial life.
The term "Mesozoic–Cenozoic radiation" generally refers to the significant diversification of life forms that occurred during the transition from the Mesozoic Era to the Cenozoic Era, which spans roughly from 66 million years ago to the present. This period is marked by dramatic changes in the Earth's climate, the breakup of continents, and the extinction of many species, notably the non-avian dinosaurs, at the end of the Cretaceous period.
"Megadiverse countries" are a small group of nations that harbor the majority of Earth's species and are home to a significant portion of the planet's biodiversity. The term was popularized by the Conservation International organization, which identifies these countries as having high levels of species diversity, particularly in terms of plants, birds, reptiles, amphibians, fish, and mammals. There are 17 countries that are typically classified as megadiverse, which are: 1. **Brazil** 2.
The Mediterranean Biogeographic Region is one of several biogeographic regions recognized by the European Environment Agency and other ecological and environmental organizations. It is primarily characterized by its unique climate, diverse ecosystems, and rich biodiversity. Here are some key features of the Mediterranean Biogeographic Region: 1. **Geographical Scope**: This region includes areas around the Mediterranean Sea, encompassing parts of southern Europe, northern Africa, and western Asia.
Marine biogeochemical cycles refer to the processes that involve the transformation and movement of chemical elements and compounds in marine environments, including oceans, seas, and coastal regions. These cycles are crucial for understanding how life functions in the marine ecosystem, how energy is transferred between living organisms, and how nutrients and chemicals are recycled. There are several key components to marine biogeochemical cycles: 1. **Elements and Compounds**: The primary elements involved include carbon, nitrogen, phosphorus, sulfur, and others.
The Macaronesian Biogeographic Region is a distinct biogeographic area located in the North Atlantic Ocean. It comprises several archipelagos known for their unique ecosystems and biodiversity. The primary components of the Macaronesian region include: 1. **Azores**: An archipelago belonging to Portugal, located about 1,500 kilometers west of the mainland. The islands are known for their volcanic origin and diverse flora and fauna.
A list of trees and shrubs by taxonomic family typically involves organizing various species of trees and shrubs according to their taxonomic classification, particularly focusing on their family level. Below is a simplified list of some common families that include notable trees and shrubs, along with examples: ### 1. **Pinaceae (Pine Family)** - **Trees**: Pine (Pinus), Spruce (Picea), Fir (Abies), Cedar (Cedrus) ### 2.
The World Geographical Scheme for Recording Plant Distributions (WGSRPD) is a system used for categorizing and coding geographical areas for the purpose of recording plant distributions. The codes in the WGSRPD are organized based on larger geographical regions, which are then subdivided into smaller areas. As of my last update, the scheme has defined a series of codes that are alphanumeric.
The term "biogeographical puzzles" refers to various patterns and discrepancies in the distribution of species across geographical areas that challenge our understanding of ecological and evolutionary processes. Here are some notable examples of biogeographical puzzles: 1. **The Wallace Line**: Proposed by Alfred Russel Wallace, this boundary separates the ecozones of Asia and Australia, with distinct differences in species despite proximity. This raises questions about how species evolve and disperse.
A list of biogeographic provinces refers to the classification of different regions of the world based on their distinct ecological and biological characteristics, including flora and fauna. These provinces help in understanding the distribution of species and ecosystems, and they are often used in conservation biology and biodiversity studies. One of the commonly referenced systems for classifying biogeographic provinces is the "Wallacean biogeographic regions," which divides the world into several major areas based on the distribution of terrestrial animals.
The Balkans are home to a diverse range of flora, including many endemic plants that are unique to this region. The term "endemic" refers to species that are native to a particular geographic area and not found naturally anywhere else. The Balkan Peninsula's varied climate and topography contribute to its rich biodiversity. Some notable genera and species of Balkan endemic plants include: 1. **Adenocarpus decorticans** - A shrub or small tree endemic to parts of the Balkans.
Landscape limnology is the study of freshwater ecosystems, particularly lakes, rivers, and wetlands, in the context of their surrounding landscapes. It combines principles from limnology, which is the scientific study of inland waters, with landscape ecology, which focuses on the relationship between spatial patterns and ecological processes.
