Translocations of threatened plants in the Mediterranean Basin: current status and future directions

Plant Ecology, Journal Year: 2023, Volume and Issue: 224(9), P. 765 - 775

Published: March 4, 2023

Abstract The Mediterranean Basin is one of the World’s plant diversity hotspots and a region prone to several anthropic pressures, besides being areas most susceptible climate change. In this region, which hosts high percentage threatened species, there has been large increase in practical conservation actions prevent extinction many plants or improve their status. framework, translocations have become increasingly important. To obtain picture status depict possible directions, data on was collected through available databases, national experts, grey literature online. Overall, list 836 relating 572 species found. These are mainly concentrated Spain, France, Italy (c. 87%) and, except for some pioneering actions, strongly increased starting from 2010. A subsequent in-depth bibliographic search scientific databases conducted determine how much information about documented literature. This resulted 133 peer-reviewed papers, only 17 describing more as whole, reporting 101 experiences carried out 56 species. Our research highlighted great discrepancy between scarce documentation comparison number out. experience gained these constitutes an enormous heritage potentially implement necessary preserve Basin.

DdRAD sequencing of the endangered species Primula Palinuri Petagna reveals high levels of inter-population diversity

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 30, 2025

Population genetics studies provide information regarding genetic diversity and structure of populations. This can in turn be used to inform conservation strategies. In view programmed efforts, we aimed at investigating the composition Primula palinuri Petagna, an endemic vulnerable species Southern Italy. Ninety-one individuals P. from seven populations were investigated using double digest Restriction Associated DNA sequencing (ddRAD-seq) a total 99,014 Single nucleotide polymorphisms (SNPs) identified. Low levels heterozygosity (0.08-0.12) high kinship (0.20-0.30) inbreeding (0.34-0.49) detected all study Kinship computed irrespective population was low, suggesting that level inter-population relatedness is low. Analysis showed differentiated each other formed three major clusters, broadly corresponding geographic sampling locations. We identified SNPs mostly contributing separation reduced set 40 successfully discriminate between clusters. conclusion, our shows sampled have low heterozygosity, intra-population variability variability.

Maternal effects and inbreeding depression in post‐translocation progeny of Campanula glomerata

Plant Biology, Journal Year: 2024, Volume and Issue: 26(3), P. 427 - 436

Published: March 1, 2024

Evaluation of plant translocation success based on fitness-related quantitative traits combined with molecular markers may contribute to a finer assessment inbreeding, selective and rescue processes, which might have long-term consequences for population dynamics viability. We investigated fitness (seed germination, seedling viability, juvenile growth mortality) 15 microsatellite loci the first post-translocation seed progeny from two translocated populations Campanula glomerata, an insect-pollinated, self-incompatible perennial herb. examined whether heterosis through admixture, site maternal transplant source origin lineage affect quality in controlled cultivation conditions. Flower production germination transplants was higher one sites, be related differences soil vegetation composition cover. Strong effects were found size, largest producing progeny. The rosette diameter maintained across whole period measured. There inbreeding depression (rather than heterosis) biparental at early stage, also expressed mortality. Our findings highlight that origin, especially when sources consisted small, fragmented remnants, value generations. If persist, they global genetic diversity patterns long term. Further admixture next generations buffer or lead outbreeding depression.

Guiding seed movement: environmental heterogeneity drives genetic differentiation in Plathymenia reticulata, providing insights for restoration

Published: May 29, 2024

Abstract Forest and landscape restoration is one of the main strategies for overcoming environmental crisis. This activity particularly relevant biodiversity-rich areas threatened by deforestation, such as tropical forests. Efficient long-term requires understanding composition genetic structure native populations, well factors that influence these components. because populations serve seed sources and, therefore, gene reservoirs under restoration. In present study, we investigated environmental, climatic spatial distance on patterns Plathymenia reticulata, aiming to support translocation areas. We collected plant samples from nine P. reticulata in state Bahia, Brazil, located Atlantic Savanna, across four types, genotyped them using nuclear three chloroplast microsatellite markers. The evaluated generally showed low moderate genotypic variability haplotypic diversity. within Savanna phytophysiognomy values above average six eight diversity parameters. Using this classification based demonstrated a high predictive power differentiation reticulata. Furthermore, interplay climate, soil geographic influenced spread alleles landscape. Based our findings, propose translocation, taking into account biome, with restricted use acquired or same environment be restored (Savanna Forest).

Defining Populations and Predicting Future Suitable Niche Space in the Geographically Disjunct, Narrowly Endemic Leafy Prairie-Clover (Dalea foliosa; Fabaceae)

Conservation actions for rare species are often based on estimates of population size and number, which challenging to capture in natural systems. Instead, many definitions populations rely arbitrarily defined distances between occurrences, is not necessarily biologically meaningful despite having utility from a conservation management perspective. Here, we introduce case study using the narrowly endemic highly geographically disjunct leafy prairie-clover (Dalea foliosa), use nuclear microsatellite loci assess current delimitations units across its entire known range. We model future potential suitable niche space how currently could fare under predicted changes climate over next 50 years. Our results indicate that genetic variation within extremely limited, particularly so distal portions range (Illinois Alabama). Within core (Tennessee), structure consistent with as defined. models may only marginally overlap geology associated this (limestone glades dolomite prairies) by 2070. Additional studies needed evaluate extent ecologically adapted local environments what role play translocation efforts.

Sibship and parentage reconstruction as genetic tool for designing and monitoring plant translocations

Restoration Ecology, Journal Year: 2022, Volume and Issue: 31(3)

Published: May 15, 2022

Estimating contemporary effective population size ( N e ), sibship and parentage can be useful for designing monitoring plant translocations. Contemporary is an important indicator of viability, as it considers several demographic factors, e.g. sex ratio, mate compatibility, inbreeding, nonrandom mating, family size. Sibship analyses allow not only estimating genetic relatedness transplants post‐translocation generations, but also selfing rates, parent contributions to offspring seed pollen dispersal. assignment method was used reconstruct pedigree estimate , rate, dispersal in wild (used sources translocation) translocated populations the self‐compatible, insect‐pollinated Dianthus deltoides (Caryophyllaceae). Source show very small estimates (5–21) high rates (28.6–68.9%), despite census sizes. The first generation (recruits transplant progeny) showed (19–53) substantial (8.4–22.3%), flowering sizes, overall diversity multiple paternity. Parentage assignments revealed levels admixture between sources, restricted successful—often restricted—pollen generation. Pollinator service, crosses selfed or related floral display, may have contributed patterns populations. present findings support interest reconstruction tool translocations, emphasizing importance assessing quality transplants, contributing a more precise evaluation extinction risk.
