“…Within this legal context, an integrated conservation program was developed on the species and its habitat including in situ , ex situ and legal measures. As a result, a range of ex situ conservation techniques has already been done [ 14 ] including the implementation of population reinforcements [ 5 , 15 ].…”

Pre-Holocene Origin for the Coronopus navasii Disjunction: Conservation Implications from Its Long Isolation

et al. 2016

Integration of unexpected discoveries about charismatic species can disrupt their well-established recovery plans, particularly when this requires coordinate actions among the different governments responsible. The Critically Endangered Coronopus navasii (Brassicaceae) was considered a restricted endemism to a few Mediterranean temporary ponds in a high mountain range of Southeast Spain, until a new group of populations were discovered 500 km North in 2006. Ten years after this finding, its management has not been accommodated due to limited information of the new populations and administrative inertia. In this study, DNA sequences and species distribution models are used to analyse the origin of the C. navasii disjunction as a preliminary step to reassess its recovery plan. Molecular results placed the disjunction during Miocene-Pleistocene (6.30–0.49 Mya, plastid DNA; 1.45–0.03 Mya, ribosomal DNA), which discards a putative human-mediated origin. In fact, the haplotype network and the low gene flow estimated between disjunct areas suggest long-term isolation. Dispersal is the most likely explanation for the disjunction as interpreted from the highly fragmented distribution projected to the past. Particularly, a northward dispersal from Southeast is proposed since C. navasii haplotype network is connected to the sister-group through the southern haplotype. Although the reassessment of C. navasii conservation status is more optimistic under the new extent of occurrence, its long-term survival may be compromised due to the: (1) natural fragmentation and rarity of the species habitat, (2) genetic isolation between the two disjunct areas, and (3) northward shift of suitable areas under future climate change scenarios. Several ex-situ and in-situ conservation measures are proposed for integrating Central East Spanish populations into the on-going recovery plan, which still only contemplates Southeast populations and therefore does not preserve the genetic structure and diversity of the species.

“…Even if the translocations included in our database were all aimed at leading to a viable population, they sometimes contain other objectives such as experimentation (e.g. Colas et al, 2008;Dalrymple & Broome, 2010;Sainz-Ollero & Hernández-Bermejo, 1979), ecological restoration (Kiehl & Pfadenhauer, 2007) or ecosystem service supply (Arnold et al, 2005;Walter, 2005). In addition, the way in which sites are selected varies.…”

Plant translocations in Europe and the Mediterranean: Geographical and climatic directions and distances from source to host sites

et al. 2021

Although the number of plant translocations has been rapidly increasing for two decades, no study is available to date that examines the directions and distances of plant displacements, which is essential (though not sufficient) information for considering translocations as a management tool to enable species to cope with the consequences of climate change. In this paper, we study the geographical and climatic directions and distances from source to host sites in 638 source‐and‐host site pairs of plant translocations that aimed to achieve viable populations in the last decades in the Western Palearctic (Europe and the Mediterranean). Translocation distances ranged from 0 to 661 km, but were generally short, most (82%) being <25 km, due to both ecological considerations and legal and administrative constraints. The host sites were not preferentially located in any geographical direction or in any altitude relative to the source sites. In contrast, on a climate compass constructed from a principal component analysis of seven bioclimatic variables, the host sites were slightly, but significantly, under colder climatic conditions than the source sites. This observation appears more to be the consequence of an effort to counteract already felt effects of climate change than to anticipate future changes. The climatic distance between source sites and actual host sites was generally smaller than between source sites and randomly selected host sites at a given distance or within a given geographical area, which may be the result of a desire to minimise climatic differences or differences in other ecological factors correlated with climatic differences. Synthesis. This study is the first to compare, geographically and climatically, the source sites of biological material and the host sites in translocations of wild plant species to obtain viable populations. Past translocations in the Western Palearctic are in line with mitigating the consequences of global warming on plant species because the host sites were in slightly cooler conditions than the source sites. Despite this, climate considerations seem to have little been taken into account in plant translocation projects and will certainly have to be much more so in a future with rapid anthropogenic climate change.

En este trabajo se analizan los sedimentos arqueológicos de cuatro túmulos megalíticos, encuadrados cronológicamente, entre el V y el 111 milenio a. C. , situados en la provincia de Lugo. Tras considerar la vegetación actual, se estudian las secuencias obtenidas a partir de los diagramas polinicos, sumándose estos resultados, a los obtenidos por Ramil Rego en 1992 para las sierras septentrionales de esta provincia.
