Fig. 16 in Extraordinary morphological changes in valve morphology during the ontogeny of several species of the Australian ostracod genus Bennelongia (Crustacea, Ostracoda)

Fig. 16. Lateral views of carapaces of Bennelongia cf. barangaroo nov. sp. from McNeil Claypan. Left column displays carapace in right lateral view, right column shows carapaces in left lateral view. Note the pronounced asymmetry between the adult valves and the less-pronounced beak-like feature of the anteroventral region of the adult LV. Pseudo-punctation is more pronounced in the younger instars and the domes and cones are only clearly visible in A-3 specimens, although remnants remain in the last two juvenile stages.

Fig. 17. Dorsal views of carapaces of Bennelongia cf. barangaroo nov. sp. from McNeil Claypan. Observe the coarse reticulation in A-3 specimens and the pseudo-punctuation that becomes less visible with progressing ontogeny. The adult specimen in top left image displays some agglomeration of glue along the hinge, particularly in the anterior and posterior regions.

Fig. 13. Bennelongia kimberleyensis Martens et al., 2012 from Taylor's Lagoon. Dorsal views of carapaces of different moult stages going from adult to A-4. Note the highly ornamented A-4 carapace with at least 2 sets of domes (and prominent cones) that are still visible in A-3, and not visible in the other stages. Only a few cones are seen in the A-1 specimen, and no ornamentation is visible in the adult specimen.

Fig. 8. External views of carapaces of Bennelongia cf. nimala nov. sp. juveniles from Muggon Lake, showing left valves in order to compare the ornamentation between an A-2 specimen (top) and A-3 specimen (bottom). The circles, ellipses and polygons are used to define the ornamentations that are common to both specimens. The arrows indicate a clear depression, postero-dorsally to each dome, that are linked by a white line.

Note also that claws of some limbs are protruding from the closed valves. Bottom right. enlargement of cone and associated lip and protruding seta of an A-3 specimen. Note the presence of fine particulate material stuck to the valve.

Fig. 1 in Extraordinary morphological changes in valve morphology during the ontogeny of several species of the Australian ostracod genus Bennelongia (Crustacea, Ostracoda)

Fig. 1. SEM photographs showing detailed internal views of the anterior portion of the right valves to highlight key features. Top: Adult Right valve (=RV) of Bennelongia gwelupensis Martens et al., 2012 from Lake Gwelup, that clearly displays the lapel, characteristic of right valves of Bennelongia adults, which is seen as an extension of the old valve margin. The selvage in this species is very well pronounced. Bottom: Last instar (=A-1, standing for adult-1 stage) of Bennelongia gwelupensis Martens et al., 2012 from Katanning Road pool. Note the prominent inner list that is rarely seen in A-1 specimens in species of Cyprididae, except in Bennelongia species, and the well calcified selvage replacing the valve margin.

Plant life history data as evidence of an historical mixed-severity fire regime in Banksia woodlands

Context: The concept of the fire regime serves as an agreed upon template by which to inform understanding and management of fire-prone ecosystems globally. While observations from satellite imagery or palaeoecological proxy data can provide direct evidence of past fire regimes, they may be limited in temporal and/or spatial scale and are not available for all ecosystems. However, fire-related plant trait and demographic data offers an alternative approach to understand species-fire regime associations at the ecosystem scale. Aims: We aimed to quantify the life history strategies and associated fire regimes for six co-occurring shrub and tree species from fire-prone, Mediterranean climate Banksia woodlands in southwestern Australia. Methods: We collected static demographic data on size structure, seedling recruitment, and plant mortality across sites of varying time since last fire. We combined demographic data with key fire-related species traits to define plant life history strategies. We then compared observed life histories with a priori expectations for surface, stand-replacing, and mixed-severity fire regime types to infer historical fire regime associations.Key results: Fire-killed shrubs and weakly serotinous trees had abundant post-fire seedling recruitment, but also developed multi-cohort populations during fire-free periods via inter-fire seedling recruitment. Resprouting shrubs had little seedling recruitment at any time, even following fire, and showed no signs of decline in the long absence of fire likely due to their very long lifespans. Conclusions: The variation in life history strategies for these six co-occurring species is consistent with known ecological strategies to cope with high variation in fire intervals in a mixed-severity fire regime. While resprouting and strong post-fire seedling recruitment indicate a tolerance of frequent fire, inter-fire recruitment and weak serotiny is interpreted as a bet-hedging strategy to cope with occasional long fire-free periods that may otherwise exceed adult and seed bank lifespans. Implications: Our findings suggest that Banksia woodlands have evolved with highly variable fire intervals in a mixed-severity fire regime. Further investigations of species adaptations to varying fire size and patchiness can help extend our understanding of fire regime tolerances.

The dataset contains some of the outputs from the global climate model experiments by MIROC5 on changing Siberian wildfire severities, the other data used in the paper (see READ_ME files on the data sources), the analyzed data, and the scripts for analyses, which were used in the following submitted paper. Note that this dataset also includes unused data for the paper: Yasunari, T. J., D. Narita, T. Takemura, S. Wakabayashi, and A. Takeshima, Comprehensive Impact of Changing Siberian Wildfire Severities on Air Quality, Climate, and Economy: MIROC5 Global Climate Model's Sensitivity Assessments, submitted. Please read the READ_ME files for detailed information in each directory (especially see the "about_figures_and_tables/" directory first). Because of their large sizes, the data were separated into three zipped files.
