ABSTRACTWe sampled individual growth rings from three ancient remnant bald cypress (Taxodium distichum) trees from a massive buried deposit at the mouth of the Altamaha River on the Georgia Coast to determine the best technique for radiocarbon (14C) dating pretreatment. The results of our comparison of traditional ABA pretreatment and holocellulose and α-cellulose fractions show no significant differences among the pretreatments (<1 sigma) thereby suggesting that ABA pretreatment will prove sufficient for the development of a high-resolution 14C tree-ring chronology based on these ancient bald cypresses which will indicate whether the U.S. Southeast is subject to a regional radiocarbon offset.

The mechanisms of cancer cell adaptation to tumor microenvironmental conditions, such as hypoxia and nutrient starvation, are currently receiving much attention as possible therapeutic targets. In an attempt to identify selectively cytotoxic substances against cancer cells adapted to nutrient starvation, 4 abietane-type diterpenes, sugiol (1), 6-α-hydroxysugiol (2), cryptojaponol (3), and 6-hydroxy-5,6-dehydrosugiol (4), were isolated from the bark of Taxodium distichum L. Rich var. distichum (bald cypress). Compounds 1, 2, and 4 showed potent cytotoxic activity against PANC-1 cells adapted to nutrient-starved conditions with half-maximal effective concentration (EC50) values of 6.4-9.2 µM, whereas the EC50 values of these compounds against PANC-1 cells under general culture conditions were more than 100 µM. Alternatively, compound 3, which we report for the first time in the genus Taxodium, showed moderate cytotoxicity against PANC-1 cells under nutrient-starved conditions with an EC50 of 37.9 µM. The selective index (S.I.), which compared the activity under nutrient-starved conditions with that under general culture conditions, was low (7.9). Further investigation revealed that the selective cytotoxic activity of compound 2 might be affecting the mitochondria.

Humans design infrastructure for human needs, with limited regard for the needs of nonhumans such as animals and plants. Humans also often fail to recognise nonhuman lifeforms such as trees as fellow engineers designers, or architects, even though the contribution of trees to ecosystem services is well established and their right to justice ought to be recognised. Studies have shown that flood-control infrastructure near the Mississippi River inadvertently left Southern Louisiana more vulnerable to coastal threats. We examine this characteristic outcome and identify infrastructural injustices in multispecies communities. Based on theories in philosophy and design supported by historical analyses, we defend the proposals to extend 1) the understanding of resilience to include more-than-human communities; and 2) the notion of justice to include non-human stakeholders. The reframing in more-than-human terms is already under way in a variety of disciplines. However, these efforts rarely extend into considerations of practical design and have attracted criticism for insufficient engagement with historical processes and the accumulations of power and responsibility. To illustrate these injustices, we trace the history of bald cypress trees (Taxodium distichum) in the Mississippi River Delta and show how infrastructure impacted the trees. This analysis demonstrates that designs that do not consider the needs of vulnerable stakeholders can cause harm in multispecies communities. In response, we propose that humans can work to improve infrastructural resilience by including humans and nonhumans as collaborators.

Bald cypress is monoecious, long-lived, deciduous conifer. It belongs to the family Taxodiaceae and genus Taxodium. In Serbia, there is only Taxodium distichum (L.) Rich. that mostly can be found in the green areas of major cities. The possibility of wider application of Bald cypress as a forest species should be based on an assessment of its genetic and adaptive potential, quantity and quality of yield, primarily at the level of the existing Bald cypress seed stand. In this paper are presented research results of the variability in cone morphometric characters among 20 test trees. The determined values of cone dimensions indicate good genetic and adaptive potential of this species that can be considered as starting point for the mass production of quality seed and planting material in Serbia.
