Biodiversity or biological diversity is a relatively new term in ecology. It became popular in the 1980s and is not yet properly understood by all non-ecologists. Biodiversity refers to the variety and richness among living organisms and the ecological systems and processes of which they are a part. There are three levels of biodiversity: habitat or ecosystem diversity, genetic diversity, and species diversity. This publication was produced by the Center for Natural Resources at the University of Florida. CNR 4 is part of a Program Summary Series. First published: September 2000. Minor revision: March 2003.  https://edis.ifas.ufl.edu/cr004

Though the concept of nature-based tourism is not new, the term "ecotourism" is. Once referred to as "green travel", ecotourism is defined as a "recreational and educational experience that encourages greater understanding of the natural and cultural resources of an area". This publication was produced by the Center for Natural Resources at the University of Florida. CNR 7 is part of a Program Summary Series. First published: September 2000. Minor revision: March 2003.

Earthworms in the family Lumbricidae in Alaska, which are known from coastal regions, primarily in south-central and south-eastern Alaska, are thought to be entirely non-native and have been shown to negatively impact previously earthworm-free ecosystems in study regions outside of Alaska. Despite occasional collections by curious citizens, there had not been a standardised earthworm survey performed in Interior Alaska and no published records exist of earthworms species from this region. Mustard extraction was used to sample six locations that differed in elevation, mostly in the College region of Fairbanks, Alaska. Two of the six locations yielded earthworms. There was no relationship between earthworm abundance and elevation (p = 0.087), although our sample size was small. Our sampling, combined with specimens in the University of Alaska Museum, has documented four exotic species and one presumed native species of lumbricid earthworms in Interior Alaska.

<p style="text-align: justify;">A introdução, acidental ou deliberada, de espécies exóticas por diferentes vetores é atualmente uma das principais mudanças globais, resultando em uma série de problemas. Embora nem todas as introduções de espécies não nativas possuam efeitos negativos, muitos desses táxons podem desencadear efeitos indesejáveis sobre a biodiversidade, desde o nível genético até o nível de paisagens. Este trabalho visou apresentar o conhecimento atual sobre as invasões biológicas por espécies vegetais, particularmente, sobre a invasora <em>Cryptostegia madagascariensis</em> Bojer ex Decne. Novas introduções são feitas anualmente em todo o mundo e apenas uma pequena parte desses táxons se tornam invasores, mesmo assim, causam sérios danos aos ecossistemas invadidos. O sucesso das plantas infestantes deve-se às características intrínsecas dessas espécies, que garantem as mesmas vantagens competitivas com as espécies nativas e ao nível de perturbação dos novos nichos, que torna os ambientes totalmente favoráveis ao estabelecimento de novas espécies e ao surgimento de áreas monodominadas. Nesse contexto, encontra-se <em>C. madagascariensis</em>, trepadeira de origem da ilha de Madagascar, na África, que foi introduzida no Brasil com fins ornamentais, tornando-se invasora de ecossistemas naturais, principalmente em ambientes de mata ciliar e baixadas úmidas, no domínio da Caatinga e ecossitemas associados.</p><p style="text-align: justify;"><strong>Palavras chave</strong>: Espécies exóticas, Caatinga, salinização, déficit hídrico.</p><p style="text-align: justify;"><strong>Abstract</strong>: The introduction, accidental or deliberate, of exotic species by different vectors is currently a major global changes, resulting in a number of local and global problems. Although not all introductions of non-native species have negative effects, many of the non-native species can have undesirable effects on biodiversity from the genetic level to the landscape. This work aimed to present the current knowledge on biological invasions by species and particularly on invasive <em>Cryptostegia madagascariensis</em> Bojer ex Decne. New introductions are made every year around the world and only a small part of these taxa become invasive, yet cause serious damage to ecosystems invaded. The success of weed plants is due to the intrinsic characteristics of these species that ensures the same competitive advantages with native species and the level of disruption in new niches which makes them totally supportive environments to establish new species and the emergence of monodominadas areas. In this context is <em>C. madagascariensis</em>, origin of climbing on the island of Madagascar in Africa, which was introduced in Brazil with ornamental purposes, becoming invasive in natural ecosystems, especially in riparian environments and humid lowlands, in the field of savanna and associated ecosystems.</p><p style="text-align: justify;"><strong>Key words</strong>: Exotic species, Caatinga, salination, deficit hydride.</p>

Abstract. The growing concern for loss of services once provided by natural ecosystems is getting increasing attention. However, the accelerating rate of natural resources destruction calls for rapid and global action. With often very limited budgets, environmental agencies and NGOs need cost-efficient ways to quickly convince decision-makers that sound management of natural resources can help to protect human lives and their welfare. The methodology described in this paper, is based on geospatial and statistical analysis, involving simple Geographical Information System (GIS) and remote sensing algorithms. It is based on free or very low-cost data. It aims to scientifically assess the potential role of vegetation in mitigating landslides triggered by earthquakes by normalising for other factors such as slopes and distance from active fault. The methodology was applied to the 2005 North Pakistan/India earthquake which generated a large number of victims and hundreds of landslides. The study shows that if slopes and proximity from active fault are the main susceptibility factors for post landslides triggered by earthquakes in this area, the results clearly revealed that areas covered by denser vegetation suffered less and smaller landslides than areas with thinner (or devoid of) vegetation cover. Short distance from roads/trails and rivers also proved to be pertinent factors in increasing landslides susceptibility. This project is a component of a wider initiative involving the Global Resource Information Database Europe from the United Nations Environment Programme, the International Union for Conservation of Nature, the Institute of Geomatics and Risk Analysis from the University of Lausanne and the "institut universitaire d'études du développement" from the University of Geneva.

Abstract Globally, urban ecosystems provide important green spaces for biodiversity conservation. Many exotic species are grown in tropical urban ecosystems, and their harmful effects on native species and pollinator communities have been widely documented. Therefore, the purpose of this research is to determine the origin (native or exotic to Indonesia, sexual and reproductive system) of tree species on the University of Sumatera’s (USU) campus. Field inventory methods were used in this study for observed tree species on the USU campus. All tree species were observed, their flowering observed if any. According to our research, the USU green area comprises a collection of 121 tree species. Seventy species (57.85 %) are native to Indonesia, while 51 species (42.15 %) are exotics from other tropical regions. In terms of individual abundance, these values are 37.28% native and 62.72% exotic. The exotic trees on the USU campus show monoecious and dioecious flower sexuality; 19 species are hermaphrodite, two species have self-incompatibility characters, seven species are dioecious, and 23 species are monoecious. Together with the results from the few other experimental studies, it concluded that the increase of exotic species plantation in USU campus might indicate risk for animal interactions (e.g., pollination; dispersal), threaten reproduction of native plant species, pollination specialization, habitat, and other life-history properties. Therefore, the use of these exotic species needs special attention for stakeholders at USU.

FloRunTM ‘331’ peanut variety was developed by the University of Florida, Institute of Food and Agricultural Sciences, North Florida Research and Education Center near Marianna, Florida.  It was released in 2016 because it combines high yield potential with excellent disease tolerance. FloRunTM ‘331’ has a typical runner growth habit with a semi-prominent central stem and medium green foliage.  It has medium runner seed size with high oleic oil chemistry.
