Here we highlight major results from over a decade of research on endangered magnolias in western Mexico. Particularly, we compare three species of Magnolia (M. pugana, M. pacifica and M. vallartensis) along a large-scale continentality and moisture gradients, in terms of a) their morphological adaptations, b) genetic structure, diversity, and differentiation, c) reproductive phenology, and d) floral scents and their floral visitors. Fieldwork along this gradient unveiled two new species of Magnolia sect. Magnolia; M. granbarrancae and M. talpana. We found that most continental populations have a higher extinction risk than those with greater maritime influence, due to their lower genetic diversity, and greater fragmentation, isolation, and water stress. Also, these populations are more vulnerable to the environmental conditions predicted with the global warming climate scenarios. We share fieldwork experience and advise on pre-germination treatments and seed dormancy. We propose an ex-situ and in-situ conservation strategy, identify new challenges, and suggest future directions of collaborative work as a global Magnolia conservation consortium.","PeriodicalId":394889,"journal":{"name":"Endangered Plants","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134564748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
{"title":"Noteworthy Threatened Plant Species in the Sahel Region, Nigeria","authors":"Abdallah Muhammad Salihu, R.

The Sahel region and some part of the savannah region bordered which faced the menace of drought and desertification which lead to so many factors like soil erosion, distraction of the ecosystem entirely. Moreover, the plants destroyed were mostly aromatic plants which served as medicines in curing many ailments and diseases contributed to the economic status of the communities found in the Sahel. The plants species became threatened to the human practices by noticing their effects for their well-being. Consequently, among the species that were threatened include: Neocarea macrophylla Prance ex F.White (Gawasa), Sclerocarya birrea (A. Rich) Hochst. (Danya), Detarium microcarpum Harms. (Taura), Prosopis africana, (Kirya), Acacia africana, Acacia nilotica and Azadirachta indica. Hence, the major concern of this chapter is to assess some of the threatened species found in the Sahel region, Nigeria and to highlight the valuable medicinal plants at risk of extinction according to the guidelines of the International Union for the Conservation of Nature (IUCN).","PeriodicalId":394889,"journal":{"name":"Endangered Plants","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121132219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increase in the number of endangered plants acts as an alarming sign of ecosystem’s imbalance. The ecological failure pose threat to our own health, thus by saving endangered species our own health is being saved. Government, non-profit international organizations, local communities and individuals are working together to protect and restore population levels. Biological Diversity Act (2002) for conservation of biodiversity is a landmark effort by Indian government as it provides mechanisms for knowledge, sustainable use of components of biological diversity and fair and equitable sharing of the benefits arising out of the use of biological resources. The various awareness campaigns have been conducted for local communities with regard to the conservation of endangered species. Both in-situ (on site) and ex-situ (off site) conservation strategies target critical habitats under continuous threat of extinction. Conservation programmes that centred mainly on the local masses which completely depend upon the environment including forests, lakes and wildlife for their needs truly showcase the leadership of local and indigenous communities in protecting biodiversity. The rights of local communities in decision making must be recognized and supported through clear laws and regulations. Sacred groves, a legacy of prehistoric traditions of nature conservation act as an ideal centre for biodiversity conservation. Besides providing vital ecosystem services to people, these are of immense ecological significance. Community conservation is the need of the hour in terms of conserving biodiversity at ground level.","PeriodicalId":394889,"journal":{"name":"Endangered Plants","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129238593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
