title: Propagules collected from Marion Island expeditioners

description: This data set examines the seeds in the clothing of expeditioners returning from Marion Island
description: Management of non-native species introductions is a conservation priority in the Antarctic region. However, despite the recognised importance of intra-regional propagule transfer, the majority of studies have focused on inter-regional pathways (i.e. from outside of the Antarctic region). Therefore, we quantified the number of seeds carried by expeditioners who have visited sub-Antarctic Marion Island and which could potentially be transported to other islands in the region .

title: Phenotypic variation in Xenopus laevis tadpoles from contrasting rainfall regimes is the result of adaptation and plasticity

description: Phenotypic variations between populations often correlate with climatic variables. Assessing the adaptation of a species' populations from differing environments over a large spatial scale can provide insight into the mechanisms such as local adaptation and phenotypic plasticity that can result in a species persistence in heterogeneous environments. Amphibians, and especially their larvae, are good models for studies of phenotypic variation as they are especially sensitive to the immediate environment. Few studies have attempted to determine the mechanisms that drive phenotypic variation among populations over a large spatial scale in amphibians especially across contrasting climatic regimes. The African clawed frog, Xenopus laevis, occurs in two regions with contrasting rainfall regimes in southern Africa. We hypothesise that the phenotypic variation of life history traits of X. laevis tadpoles from these regions is a result of a combination of plastic and adaptive responses. We measured larval life history traits such as size development, time to metamorphosis and survival variation in a reciprocal exchange experiment using outdoor mesocosms. Supporting our prediction, we found that the measured variation of all traits was explained by both adaptation and plasticity. However, the reaction norms differed between populations suggesting adaptive plasticity. The phenotypic response to translocation, additionally, came at a cost, as survival was significantly lower when tadpoles were translocated rather than reared in their environment of origin. Our study demonstrates that there is both a genetic and non-genetic basis for phenotypic differences in amphibian larvae, which can explain the persistence across two contrasting rainfall regimes.

title: Does the spatial sorting of dispersal traits affect the phenotype of the non-dispersing stages of the invasive frog Xenopus laevis through coupling?

description: In amphibians, spatial sorting progressively enhances the dispersal capacities of dispersing stages in expanding populations but may enhance or limit the performance of the earlier non-dispersing stages. Phenotypic traits of non-dispersing tadpoles and metamorphs can be coupled, through carryover effects and trade-offs, or decoupled to dispersal traits in adults. We used the globally invasive amphibian, Xenopus laevis, to examine whether spatial sorting of adult phenotypes affects the phenotype of larval stages to metamorphosis in the core and at the periphery of an invasive population in France. We combined common garden laboratory and outdoor experiments to test the effect of parental pond location (core or periphery) on morphology, development and survival to metamorphosis and found no differences between tadpoles. After metamorphosis, the only difference observed in either of the experiments was the larger body size of metamorphs from the periphery, and then only when reared in the laboratory. Differences in metamorph size may indicate that a shift of dispersal traits occur after metamorphosis in X. laevis. Thus, our findings illustrate that decoupled evolution through spatial sorting can lead to changes of X. laevis adult phenotypes that would enhance dispersal without affecting the phenotype of tadpoles before metamorphosis.

title: Anti-predator strategies of the invasive African clawed frog, Xenopus laevis, to native and invasive predators in western France (dataset)

description: When species are translocated to a novel environment, individuals become exposed to new predators against which they may not express very efficient defences at least at an initial stage. The strength of anti-predator defence is an important parameter that may determine the ability of local communities to control the expansion of invasive populations. The African clawed frog, Xenopus laevis, is a globally invasive amphibian that has successfully established invasive populations on four continents. In its invasive distribution in western France, X. laevis encounters novel aquatic predators. Some may be related to the predators in the native range but others may belong to different taxonomic groups and not be functionally or ecologically equivalent. We tested whether naïve X. laevis tadpoles from the invasive French population exhibit anti-predator response to local predators, and whether the response depends on the degree of relatedness with predators encountered in the native range of the frog, or whether individuals may express generic neophobia to any cue they are not familiar with. We exposed naïve lab-reared tadpoles to a native non-predatory water snail, Planorbarius corneus, a native predatory beetle, Dytiscus dimidiatus, and an invasive predatory crayfish, Procambarus clarkii. We found that X. laevis tadpoles innately reduce their activity when exposed to beetle and crayfish stimulus cues, but not to snails. Reducing activity can decrease the probability of being detected by predators. This demonstrates that invasive tadpoles respond to known and novel predators regardless of the evolutionary history. Whether the produced response is always effective against a totally novel predator remains to be tested.

title: Operative temperature dataset in areas with native and invasive vegetation

description: Operative temperature data collected in both "native areas" (native renosterveld vegetation) and "invaded areas" (native renosterveld vegetation areas invaded by alien trees, mainly Acacia saligna). The data were collected using simplified operative temperature models (OTM) of Homopus areolatus tortoises, in four field sites in the Western Cape, South Africa, at an hourly temporal resolution and during one year. For each field site, the data are from between 40 and 45 OTMs placed above- and under-ground and covering a range of microsites that varied in substrate and exposure to the sun.
description: The aim was to characterise the thermal landscape available to Homopus areolatus individuals in both native and invaded areas, and to explore the effects of invasive trees on the habitat's thermal quality and the individuals' thermoregulation and activity.

title: DNA barcoding of South African Ants

description: The files contain sequences and collection information from a project on barcoding South African ants. Parts of the collections were done for this purpose while other samples were derived from different ant projects in which the author was involved during her stay at the CIB. Additional samples were received as donations by other researchers. The data can be combined with the diversity and trait information collected in those projects. This includes the two long-term monitoring projects - the Iimbovane Outreach project and the Cederberg Altitudinal Transect Project (aka Coast to Karoo Transect) - and projects using the same study sites. Sequencing of samples took place at the Biodiversity Institute of Ontario at the University of Guelph as this project was in collaboration with the international Barcoding of Life Initiative and its South African collaborators. The data thus is also stored in the Barcoding of Life Database and Aggregate files of the project's data have been compiled using the web tools of this database. Voucher specimens are stored in the collection of the CIB at Stellenbosch University.
description: The main intentions were to provide a first attempt at a phylogeny for ongoing ant projects at the CIB, test morphospecies hypotheses from these projects, and provide future researchers with an additional identification tool (the data is publicily accessable via the Barcoding of Life Database. While South Africa has a long history of ant research, a large portion of it's ant species are not yet named, distributions and intraspecific variation are often poorly known, and keys - where existing - are often not to modern standards and outdated. This makes ant identification challenging and lowers the possibility to combine data from different projects. The new tool of DNABarcoding may thus help adopt this ecologically important group more frequently in research and conservation work.
