“…A list of species sampled, along with collection localities, vouchers, and accession numbers is provided in Table 2. For members of segregate genera that do not have a valid synonym within Piper, the most current classification was used (e.g., Macropiper, Smith, 1975). For every species included, floral and inflorescence structure was documented using field-collected material, and the consistency of trait expression was verified in monographic treatments and herbarium collections.…”

With ∼1000 species distributed pantropically, the genus Piper is one of the most diverse lineages among basal angiosperms. To rigorously address the evolution of Piper we use a phylogenetic analysis of sequences of the internal transcribed spacers (ITS) of nuclear ribosomal DNA based on a worldwide sample. Sequences from a total of 51 species of Piper were aligned to yield 257 phylogenetically informative sites. A single unrooted parsimony network suggested that taxa representing major geographic areas could potentially form three monophyletic groups: Asia, the South Pacific, and the Neotropics. The position of Pothomorphe was well supported among groups of New World taxa. Simultaneous phylogenetic analysis of an expanded alignment including outgroups suggested that taxa from the South Pacific and Asia formed a monophyletic group, provisionally supporting a single origin of dioecy. Within the Neotropical sister clade, resolution was high and strong bootstrap support confirmed the monophyly of several traditionally recognized infrageneric groups (e.g., Enckea [including Arctottonia], Ottonia, Radula, Macrostachys). In contrast, some of the species representing the highly polytypic subgroup Steffensia formed a clade corresponding to the previously recognized taxon Schilleria, while others were strongly associated with several of the more specialized groups of taxa. The distribution of putatively derived inflorescence and floral character states suggested that both umbellate and solitary axillary inflorescences have multiple origins. Reduction in anther number appears to be associated with highly packaged inflorescences or with larger anther primordia per flower, trends that are consistent with the suppression of later stages of androecial development.

“…10 species. A recent taxonomic revision suggests that the center of diversity of the /Macropiper is the Fijian archipelago, with six species total, three of them endemic to the region (Smith 1975). Many species of /Macropiper are used by indigenous people as remedies and the wide distribution in the South Pacific Islands may be a result of human introduction; however, no data are available to verify this hypothesis.…”

“…The native Kawakawa tree (Macropiper excelsum, Piperales: Piperaceae) is a common understory plant throughout the mixed native scrub environments of New Zealand [40]. The species is confined to coastal areas of the New Zealand mainland and a number of its offshore islands and reaches its southern limit at a latitude of 43846 0 S (Banks Peninsula) on the Pacific coast of New Zealand.…”

Gaining insight into the impact of anthropogenic change on ecosystems requires investigation into interdependencies between multiple drivers of ecological change and multiple biotic responses. Global environmental change drivers can act simultaneously to impact the abundance and diversity of biota, but few studies have also measured the impact across trophic levels. We firstly investigated whether climate (using temperature differences across a latitudinal gradient as a surrogate) interacts with habitat fragmentation (measured according to fragment area and distance to habitat edges) to impact a New Zealand tri-trophic food chain ( plant, herbivore and natural enemy). Secondly, we examined how these interactions might differentially impact both the density and biotic processes of species at each of the three trophic levels. We found evidence to suggest that these drivers act nonadditively across trophic levels. The nature of these interactions however varied: location synergistically interacted with fragmentation measures to exacerbate the detrimental effects on consumer density; and antagonistically interacted to ameliorate the impact on plant density and on the interactions between trophic levels (herbivory and parasitoid attack rate). Our findings indicate that the ecological consequences of multiple global change drivers are strongly interactive and vary according to the trophic level studied and whether density or ecological processes are investigated.
