The current paper presents some characteristics of the anatomy of vegetative organs (adventive root and leaf) of Allium saxatile M. Bieb., a species rare in the Romanian flora, which have not been described before in the literature. Histo-anatomical studies performed on Allium saxatile plants sampled from three local populations identified in the Dobrogea area, complete already existing data from other species of this genus, and represent the beginning of future studies on ecological anatomy, taxonomy and ex situ conservation strategies. Some of the obtained results confirm data from literature, but additional observations have been made that show features not reported previously for any specie of the Allium genus, such as the presence of colenchymatized cells in the internal mesophyll at the lamina level; or the presence, at sheath level, of epidermal cells with uniformly lignified and thick walls.

Seed Crops

Recent development and implementation of crop cryopreservation protocols has increased the capacity to maintain recalcitrant seeded germplasm collections via cryopreserved in vitro material. To preserve the greatest possible plant genetic resources globally for future food security and breeding programs, it is essential to integrate in situ and ex situ conservation methods into a cohesive conservation plan. In vitro storage using tissue culture and cryopreservation techniques offers promising complementary tools that can be used to promote this approach. These techniques can be employed for crops difficult or impossible to maintain in seed banks for long-term conservation. This includes woody perennial plants, recalcitrant seed crops or crops with no seeds at all and vegetatively or clonally propagated crops where seeds are not true-to-type. Many of the world’s most important crops for food, nutrition and livelihoods, are vegetatively propagated or have recalcitrant seeds. This review will look at ex situ conservation, namely field repositories and in vitro storage for some of these economically important crops, focusing on conservation strategies for avocado. To date, cultivar-specific multiplication protocols have been established for maintaining multiple avocado cultivars in tissue culture. Cryopreservation of avocado somatic embryos and somatic embryogenesis have been successful. In addition, a shoot-tip cryopreservation protocol has been developed for cryo-storage and regeneration of true-to-type clonal avocado plants.

The World

Nearly one in every five species of reptiles in the world is threatened with extinction and thus is conservation dependent. In order to develop effective and targeted species conservation strategies, detailed information on their distribution, systematics and ecology are necessary. Information such as the natural history and in-situ reproductive behaviors would be crucial for highly threatened species that require ex-situ conservation measures. Agamid lizards are a major component of the global reptile diversity and a significant number are threatened due to habitat loss and other threats such as smuggling.

Biodiversity is vital for the stability of the planet; its ecosystem services provide essential elements for our survival and well-being. This review analyzes the national biodiversity policies and describes the main strategies for biodiversity conservation in Ecuador, one of the “mega-diverse” countries in the world with the highest species density. It deepens an analysis of in-situ and ex-situ conservation processes. Ecuador has six clear policies for biodiversity conservation. These policies strengthen biodiversity conservation through mechanisms that improve the well-being of wildlife by ensuring human, wildlife and ecosystem health. It promotes actions for the welfare of wildlife, through technical, administrative and legal tools. The National System of Protected Areas, with 60 protected areas, is the most effective in-situ conservation instrument at the country level. Several ex-situ conservation and management means for the conservation of wild species are being utilized, including nurseries, botanical gardens, zoos, germplasm banks, aquariums, species reproduction and rehabilitation centers. Ecuador is making slow progress on ex-situ conservation despite the availability of a sound policy framework, possibly due to financial, infrastructural, and/or technological challenges, and knowledge gaps. We propose fostering international research collaborations and establishing fully funded small-scale captive breeding programs at zoos, aquariums and university research facilities to help recovery of at-risk species of reptiles, amphibians, fish and species beyond Galapagos region. We recommend utilizing citizen science programs to fill the gaps of biodiversity information and increasing efforts to revive the ex-situ conservation strategies in protecting the unique biodiversity of Ecuador.

Israel is a geographically small and relatively new state (founded in 1948) with high population density, industrial development and economic growth, all of which negatively affect the environment, particularly biodiversity. There is, however, a growing awareness in the country of the need for environmental and biodiversity protection. The Israel Nature and Parks Authority (INPA), the official body legally responsible for protecting natural habitats, biodiversity and ecosystems in Israel, established a program to protect and conserve the endangered, near-threatened and very rare (ENtR) plants listed in the Israel Red Data Book of flora at risk. In this communication, we describe the ex-situ conservation strategies of the Israel Gene Bank (IGB) within this program. The IGB has expanded its role in the conservation of ENtR species from only ex-situ seed conservation to active involvement in whole-plant conservation and reintroducing ENtR species back into nature. In the past 10 years, 1289 accessions belonging to 68% of the species in the Red List were collected to form the IGB core collection of endangered and rare species. The germination unit of the IGB developed 198 new protocols and propagated 87 different ENtR species.

Iron Deposits

The flora of the ferruginous Campo rupestre that occur over the immense iron deposits of the Carajás National Forest is very unique, with several endemic and rare species. This vegetation is directly affected by mining activity, as a result of vegetation suppression and the profound disfigurement of habitats. The objective of this work was to identify the ornamental potential of the flora of the ferruginous Campo rupestre, as a strategy for ex situ conservation of ecosystem species. The species present in ten plots of 5 x 5 m were surveyed in different areas of the ferruginous Campo rupestre on the N1 plateau and the ornamental potential of each species was evaluated following a characterization key, considering morphology and habitat of occurrence. Subsequently, the species were compared with those already present on the market, as ornamental, based on the literature and on sites specialized in the sale of ornamental plants in Brazil. A total of 33 species with ornamental potential were found, distributed in 32 genera and 19 families. Most species showed high functionality for ornamentation and similarity with nationally consolidated ornamentals. Catasetum planiceps, Cyrtopodium andersonii, Epidendrum nocturnum, Mandevilla scabra, Norantea guianensis and Sobralia liliastrum have a consolidated ornamental market. The data collected support ex situ conservation strategies of the flora of the ferruginous Campo rupestre, such as its valorization, local commercialization and income generation for small extractivists in the region.
