Data from: Molecular genetics unveiled unknown family relationships and hybrids in an ex-situ colony of African penguins (Spheniscus demersus)
Genealogical relationships among colony members, inbreeding status, and presence of hybrids are crucial data that can assist zoo curators in captive colony management and decision-making on relocation for reproduction. This study employed molecular markers to study a large colony (n=56) of African Penguin hosted in an Italian biopark. A panel of 15 STRs (single tandem repeats) was selected, and genotype data were analyzed using COLONY software to determine parentage relationships and compare the existing studbook information to a pedigree built from genetic analyses. The existence of extra-pair mating and the presence of hybrids were investigated: discrepancies in kinship relationships emerged following molecular parentage analysis and ten unknown genetic relationships were revealed. Infidelity of one member of the pair was observed in six cases and extra-pair copulation was assessed by genetic analysis in two episodes. One member of the colony was found to be a hybrid (S. demersus X S. humboldti); his progeny, derived by extra-pair copulation, was traced. Three other hidden hybrids were discovered and assessed using the identified candidate private alleles. Overall, our results demonstrate that molecular methods to confirm parentage and analyze relatedness among colony members are a valuable tool to complement studbook-based genetic management of African penguin captive populations. Because a variety of behavioral dynamics (e.g., extra-pair mating) can make observations ineffective in some species and because molecular markers outperform studbook in identifying the presence of hybrids, reliance on studbook information alone is not recommended.

Museomics contributes to the spatiotemporal assessment of genetic diversity and structure in wild and ex situ conservation organisms: a case study of three endangered coastal plants in Japan
<p><span>Understanding </span><span>the extent to which </span><span>genetic diversity of wild populations in ex</span> <span>situ</span><span> conservation can be retained is </span><span>crucial</span><span> for the management of </span><span>such</span><span> populations. Wild individuals collected in the target area in the past </span><span>and</span><span> present can be used to estimate the number of alleles lost over time in wild populations and</span><span> thereby</span><span> the number of alleles whose loss could be </span><span>prevented</span><span> by ex</span> <span>situ</span><span> conservation. </span><span>Here</span><span>, we assessed the genetic diversity of wild and ex</span> <span>situ</span><span> conservation populations of three endangered coastal herb species</span><span>,</span><span> <em>Cirsium maritimum</em> Makino (Asteraceae), <em>Linaria japonica</em> Miq. (Plantaginaceae</span><span>) and</span><span> <em>Suaeda glauca</em></span><span><em> </em>(Bunge) Bunge (Amaranthaceae), which are endangered </span><span>species on</span><span> Awaji Island, Hyogo Prefecture, Japan, via multiplexed inter-simple sequence repeat genotyping by sequencing (MIG-seq). We </span><span>incorporated</span><span> the museomics approach, which </span><span>involves conducting</span><span> genetic analyses of museum specimens collected from the targeted wild populations in the past to estimate the temporal transition of genetic diversity in wild populations and the number of alleles maintai</span><span>ned in <em>ex situ</em></span><span> conservation. </span><span>Our </span><span>results </span><span>reveal</span><span> a declining trend in genetic diversity in the wild populations of all </span><span>investigated</span><span> species, although </span><span>this trend is </span><span>not significant. In all the species, </span><span>numerous</span><span> alleles were already lost in current wild populations, </span><span>whereas they</span><span> were </span><span>present</span><span> in the past wild and ex</span> <span>situ</span><span> conservation populations. Our study </span><span>indicates</span><span> that extinct alleles in current wild populations have been maintained in ex</span> <span>situ</span><span> conservation</span><span> by museomics approach. These </span><span>appro</span><span>aches </span><span>were effective in verifying</span><span> the genetic diversity retention effects of <em>ex</em></span><em> <span>situ</span></em><span> conservation populations.</span></p>

Effects of ants on riparian poplars: an ex situ experiment of biotic interaction
<p>Poplars establish on alluvial bars within sand and gravel-bed rivers. Alluvial bars also provide particularly suitable habitats<br> for the proliferation of ants. We hypothesized that ants, by modifying substrate structure and resource availability in fluvial<br> habitats, positively influence poplar growth during its establishment stage. We conducted a preliminary nine-month ex situ<br> greenhouse experiment with one ant species (Lasius niger L.) and six different genotypes of poplar cuttings (Populus nigra<br> L.), both collected on the Garonne River, SW France. Three main treatments: ‘P. nigra alone’, ‘P. nigra without ants and with<br> ant food’ and ‘P. nigra with ants and ant food’ were applied. After one growing season, we tested differences in branching<br> length and biomass of stems, roots and leaves. Certain genotypes showed significant differences in growth, but there were<br> no significant differences in stem length, dry mass of stems and roots between the three treatments. The total biomass of<br> poplars after the first growing season was positively affected by the initial size of the cuttings and was modulated by the<br> genotype independently from the treatments. However, an increased poplar growth for the treatment without ants and with<br> ant food was observed according to significant differences in dry weight of leaves and total biomass (i.e. dry mass of stems,<br> roots and leaves) for the pooled genotypes across treatments. We discuss our results with the aim of serving as a reference<br> for future in situ and ex situ experiments and field measurements exploring interactions between ants and poplars, specifically<br> in riparian ecosystems.en</p>
