Data from: Flower movement balances pollinator needs and pollen protection

Flower signaling and orientation are key characteristics, which determine a flower's pollinator guild. However, many flowers actively move during their daily cycle, changing both their detectability and accessibility to pollinators. The flowers of the wild tobacco Nicotiana attenuata orientate their corolla upwards at sunset and downwards after sunrise. Here, we investigated the effect of different flower orientations on a major pollinator of N. attenuata, the hawkmoth Manduca sexta. We found that although flower orientation influenced the flight altitude of the moth in respect to the flower, it did not alter its overall attractiveness. These behavioral observations were consistent with the finding that orientation did not systematically change the spatial distribution of floral volatiles, which are major attractants for moths. Moreover, moths invested the same amount of time into probing flowers at different orientations, even though they were only able to feed and take up pollen from horizontally and upward oriented flowers, but not from downward facing flowers. The orientation of the flower was hence crucial for a successful interaction between N. attenuata and its hawkmoth pollinator. Additionally, we determined potential adverse effects of exposing flowers at different orientations to natural daylight levels, finding that anther temperature of upward oriented flowers was more than 7°C higher than for downward oriented flowers. This increase in temperature likely caused the significantly reduced germination success that was observed for pollen grains from upward oriented flowers in comparison to those of downward and horizontally oriented flowers. These results highlight the importance of flower reorientation to ensure pollen protection, while maintaining the association between flower signals and flower accessibility necessary for a successful interaction of the plant with its insect pollinators.

Distribution. Restricted and patchy range in NE Madagascar that includes the humid forest belt extending from the Marojejy Massif and the Andapa Basin to Maroantsetra; the Androranga River may be the NE distributional limit in the Tsaratanana Corridor, although further surveys are needed to confirm this, and the Antainambalana River in the Makira Forest protected area is currently regarded as the S boundary. Currently, Marojejy represents the N limit ofits distribution, although historic range maps suggest that it once occurred as far N as the Bemarivo River near Sambava. The NE distributional limit in Makira was only recently established, when a few groups were found in the Antohaka Lava Forest, but informal reports suggest that the unprotected Maherivaratra Forest, outside NE Makira, may also contain Silky Sifakas. in Indriidae

Data from: High species diversity and turnover in granite inselberg floras highlight the need for a conservation strategy protecting many outcrops

Determining patterns of plant diversity on granite inselbergs is an important task for conservation biogeography due to mounting threats. However, beyond the tropics there are relatively few quantitative studies of floristic diversity, or consideration of these patterns and their environmental, biogeographic and historical correlates for conservation. We sought to contribute broader understanding of global patterns of species diversity on granite inselbergs and inform biodiversity conservation in the globally significant Southwest Australian Floristic Region (SWAFR). We surveyed floristics from 16 inselbergs (478 plots) across the climate gradient of the SWAFR stratified into three major habitats on each outcrop. We recorded 1060 species from 92 families. At the plot level, local soil and topographic variables affecting aridity were correlated with species richness in herbaceous (HO) and woody vegetation (WO) of soil-filled depressions, but not in woody vegetation on deeper soils at the base of outcrops (WOB). At the outcrop level, bioclimatic variables affecting aridity were correlated with species richness in two habitats (WO and WOB) but, contrary to predictions from island biogeography, were not correlated with inselberg area and isolation in any of the three habitats. Species turnover in each of the three habitats was also influenced by aridity, being correlated with bioclimatic variables and with inter-plot geographic distance, and for HO and WO habitats with local site variables. At the outcrop level, species replacement was the dominant component of species turnover in each of the three habitats, consistent with expectations for long-term stable landscapes. Our results therefore highlight high species diversity and turnover associated with granite outcrop flora. Hence, effective conservation strategies will need to focus on protecting multiple inselbergs across the entire climate gradient of the region.

Comparison of adult census size and effective population size support the need for continued protection of two Solomon Island endemics

Because a population's ability to respond to rapid change is dictated by standing genetic variation, we can better predict a population's long-term viability by estimating and then comparing adult census size (N) and effective population size (Ne). However, most studies only measure N or Ne, which can be misleading. Using a combination of field and genomic sequence data, we here estimate and compare N and Ne in two range-restricted endemics of the Solomon Islands. Two Zosterops White-eye species inhabit the small island of Kolombangara, with a high elevation species endemic to the island (Z. murphyi) and a low elevation species endemic to the Solomon Islands (Z. kulambangrae). Field observations reveal large values of N for both species with Z. kulambangrae numbering at 114,781 ± 32,233 adults, and Z. murphyi numbering at 64,412 ± 15,324 adults. In contrast, genomic analyses reveal that Ne was much lower than N, with Z. kulambangrae estimated at 694.5 and Z. murphyi at 796.1 individuals. Further, positive Tajima's D values for both species suggest that they have experienced a demographic contraction, providing a mechanism for low values of Ne. Comparison of N and Ne suggests that Z. kulambangrae and Z. murphyi are not at immediate threat of extinction but may be at genetic risk. Our results provide important baseline data for long-term monitoring of these island endemics, and argue for measuring both population size estimates to better gauge long-term population viability.
