A stratigraphic evaluation of Ettingshausen’s New England Tertiary plant localities
(1990) Pickett, J. W.; Smith, N.; Bishop, P. M.; Hill, R. S.; Macphail, M. K.
Recent work on Australian Tertiary macrofloras has highlighted the importance of the writings of early workers such as Ettingshausen and Deane; placing their localities in a modern stratigraphic context is an important preliminary to further work. The setting of these localities in New England is examined, and age constraints obtained from palynological and isotope studies are used to provide controls on the stratigraphy. A correlation table of Tertiary volcanic stratigraphy in the most significant areas is provided.
Thermal Tolerance Varies Latitudinally and Broadly Mirrors Genetic Structure in the Seaweed Phyllospora comosa Across Its Entire Latitudinal Range
(2025) Harris, Rosalie J.; Bryant, Callum; Leigh, Andrea; Coleman, Melinda A.; Nicotra, Adrienne B.; Wood, Georgina
Climate-driven warming is causing rapid changes in marine environments, contracting ranges and reshaping ecosystems. Understanding how genetic structure and phenotypic variation interact to determine populations' ability to tolerate warming aids in predicting biogeographic shifts and informs conservation. We tested whether photosynthetic thermal tolerance in the habitat-forming seaweed Phyllospora comosa reflects underlying genetic differentiation across its full latitudinal range in south-eastern Australia. We sampled 15 male and 15 female individuals at replicate sites representing three previously defined genetic groups. We measured critical temperature (Tcrit) and maximum quantum yield of PSII (FV/FM) as metrics of thermal tolerance using temperature-dependent chlorophyll fluorescence, and assessed relationships with genetic group, sex, latitude and sea surface temperature (SST). We found that thermal tolerance of Phyllospora decreased by ~1°C per degree latitude, with low FV/FM in warmer low-latitude waters, indicating thermal stress. Thermal tolerance patterns loosely mirrored genetic groupings: the warm-edge group showed the greatest tolerance, while the cool-edge group was least tolerant. Considerable variation among sites within genetic groups likely reflected both genetic diversity and environmental factors. Males at the warm edge and in central groups tended to show slightly higher tolerance than females, a pattern reversed at cooler latitudes. Although the warm-edge group showed patterns consistent with local thermal conditions and exhibited higher thermal tolerance, it had poor photosynthetic health when sampled mid-summer. Geographic patterns of thermal tolerance in Phyllospora reflect a combination of genetic differentiation and environmentally driven acclimatory responses, with warm-edge populations showing high tolerance but reduced diversity and photophysiological health. Central populations which exhibited higher diversity and versatile tolerance may act as a reservoir for restoration. Combining warm-edge adaptive alleles with central diversity through controlled genetic mixing and outplanting could help future-proof kelp forest restoration under climate change.

During the COVID-19 pandemic, Malaysia adopted heterologous vaccine booster strategies using BNT162b2 (Pfizer), CoronaVac (Sinovac) and ChAdOx1 nCoV-19 (AstraZeneca) due to vaccine shortages. However, longitudinal data on immune durability and breakthrough infections, especially in immunocompromised groups, remain limited. This study evaluates humoral response in healthy individuals after primary vaccine series and booster dose, and assesses long-term hybrid immunity up to two years post-booster in both healthy individuals and immunocompromised kidney transplant recipients (KTRs). BNT162b2 vaccine elicited a stronger anti-spike (anti-S) antibody response (3.0 log U/mL) compared to CoronaVac (1.6 log U/mL) at 3 months post-second dose. Anti-nucleocapsid (anti-N) antibody seroconversion was 50.3 % in CoronaVac recipients, suggesting limited humoral responses against N protein. Booster vaccination with homologous or heterologous mRNA-based regimens (BNT162b2/BNT162b2, ChAdOx1 nCoV-19/BNT162b2, and CoronaVac/BNT162b2) further enhanced anti-S antibody responses (3.6–3.7 log U/mL) for up to 6 months, whereas homologous CoronaVac/CoronaVac boosters yielded lower antibody levels (2.8 log U/mL). Breakthrough infections triggered a rapid rise in anti-N antibody, followed by a decline back to pre-infection levels within 3 months. In individuals infected two years after booster vaccination, T cell responses increased in healthy participants but declined in KTRs despite strong antibody responses, suggesting immunosuppressive therapy may impair T cell activation. These findings highlight the need for comprehensive immune assessments to guide preventive strategies, especially for immunocompromised populations.
