title: NOAA/WDS Paleoclimatology - Montego Bay, Pedro Bank - Sclerosponge Oxygen Isotope and Sr/Ca Data

description: We investigate aragonitic skeletons of the Caribbean sclerosponge Ceratoporella nicholsoni from Jamaica, 20 m below sea level (mbsl), and Pedro Bank, 125 mbsl. We use d18O and Sr/Ca ratios as temperature proxies to reconstruct the Caribbean mixed layer and thermocline temperature history since 1400 A.D. with a decadal time resolution. Our age models are based on U/Th dating and locating of the radiocarbon bomb spike. The modern temperature difference between the two sites is used to tentatively calibrate the C. nicholsoni Sr/Ca thermometer. The resulting calibration points to a temperature sensitivity of Sr/Ca in C. nicholsoni aragonite of about -0.1 mmol/mol/K. Our Sr/Ca records reveal a pronounced warming from the early 19th to the late 20th century, both at 20 and 125 mbsl. Two temperature minima in the shallow water record during the late 17th and early 19th century correspond to the Maunder and Dalton sunspot minima, respectively. Another major cooling occurred in the late 16th century and is not correlatable with a sunspot minimum. The temperature contrast between the two sites decreased from the 14th century to a minimum in the late 17th century and subsequently increased to modern values in the early 19th century. This is interpreted as a long-term deepening and subsequent shoaling of the Caribbean thermocline. The major trends of the Sr/Ca records are reproduced in both specimens but hardly reflected in the d18O records.
description: Sr/Ca and oxygen isotope values (VPDB) were measured on aragonitic skeletons of sclerosponges Ceratoporella nicholsoni. Sr/Ca values were measured with ICP-AES with external reproducibility of 0.6% (2sem). External precision for d18O is 0.07 permil (2sd). Age model is based on U/Th dating with average error of 3%. sample Pb19: Pedro Bank, 17°32'N, 78°57'W; 125 mbsl

title: NOAA/WDS Paleoclimatology - Buchwal - Mount Iskoras - PISY - ITRDB NOR031

description: The high temperature sensitivity of pine trees in northern Fennoscandia has led to some of the most reliable tree-ring climate reconstructions in the world for the past millennia. However, wood anatomical anomalies that likely reflect temperature-induced reductions in cell wall lignification, the so-called Blue Rings (BRs), have not yet been systematically investigated in trees and shrubs in northern Europe. Here, we present frontier research on the occurrence of BRs in Pinus sylvestris trees and Juniperus communis (L.) s.l. shrubs from the upper treeline in northern Norway (69°N) in relation to instrumental temperature data covering the last ca. 150 years. The highest number of BRs was found in 1902, with 96% of Pinus trees and 68% of Juniperus shrubs showing BRs. These corresponded on average to a 42% vs. 27% proportion of the growth ring in 1902 which was less-lignified in Pinus trees and Juniperus shrubs, respectively. Another peak in BRs recorded for 1877 was more pronounced in Pinus trees (88%) than in Juniperus shrubs (36%), with a lower proportion of less lignified rings. We found the lowest monthly sums of growing degree days in June 1902 and August 1877, resulting in more uniform non-lignified BRs in 1902 than in 1877. Prolonged early growing season cooling shortened the growing season in 1902 and resulted in much thinner cell walls in trees and shrubs than in 1877, which was characterized by extended cooling at the end of the growing season. Also, after 1902 BR, Pinus trees exclusively showed no recovery in the mean cell wall thickness in the following year. Our study provides the first evidence for different impacts of early versus late growing season cooling on cell wall lignification in trees and shrubs at the northern treeline. Using the anatomy of BRs, we demonstrated the potential to refine summer cooling event reconstructions at an intra-annual resolution in northern Fennoscandia and beyond.
description: raw growth ring measurements are in mm; there are no missing rings (for more information look into associated paper published in Frontiers in Plant Science. In this study only ring width data covering the instrumental period (i.e., 1877-2022) was used. Detrending of raw series for trees and shrubs used each individual’s full timespan, extending beyond the instrumental period.

title: Effects of early season temperature on adult life history traits of wheat stem sawfly, Cephus cinctus (Hymenoptera: Cephidae) and Bracon cephi (Hymenoptera: Braconidae)

description:  Wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a long-standing and serious pest of wheat, Triticum aestivum Linnaeus (Poaceae), in the northern Great Plains region of North America. Over the last decade, research efforts have aimed to better understand C. cinctus population dynamics through the use of bioclimatic and phenology models, however, information is missing that is required to accurately parameterize a phenology model. In particular, the effects of early season weather conditions on C. cinctus and one of its primary natural enemies, Bracon cephi Gahan (Hymenoptera: Braconidae) are unknown. Our study investigated how cold early season temperatures that increase the time required for post-diapause development affect adult life history metrics (longevity, body size, lipid content, and female egg capacity) of C. cinctus and B. cephi through a series of laboratory assays using a thermal gradient plate to manipulate temperatures. We found that male C. cinctus adult longevity and lipid content decreased in response to prolonged post-diapause development time but that females were not affected. Conversely, B. cephi adult longevity (male and female) did not change under the same experimental conditions, suggesting that B. cephi is likely to stay in-sync with C. cinctus and remain as an important natural enemy. Altogether, this research increased our understanding of how early season temperatures affect C. cinctus life history parameters. This information can be used to parameterize a phenology model for C. cinctus that includes the contribution of B. cephi on its population dynamics and that could subsequently be used to forecast C. cinctus pest status population dynamics across its geographic host range.
