“…Using in situ SIMS technique to measure the oxygen isotope composition of conodont apatite (Trotter et al, 2008(Trotter et al, , 2015Rigo et al, 2012;Wheeley et al, 2012), foraminiferal calcite (Kozdon et al, 2009(Kozdon et al, , 2011, and other faunal materials (Aubert et al, 2012;Blumenthal et al, 2014;Zigaite and Whitehouse, 2014) have been well developed in recent years, with similar analytical procedures among different laboratories. At the CA-SIMS laboratory in the Institute of Geology and Geophysics, Chinese Academy of Sciences, we used a Cameca IMS-1280 SIMS, generally following the methodology developed in the SHRIMP laboratory of the Australian National University (Trotter et al, 2008(Trotter et al, , 2015.…”

Understanding the interplay of climatic and biological events in deep time requires resolving the precise timing and pattern of paleotemperature changes and their temporal relationship with carbon cycle variations and biodiversity fluctuations. In situ oxygen isotope analyses of conodont apatite from South China enables us to reconstruct high-resolution seawater temperature records across the Permian-Triassic boundary (PTB) intervals in the upper slope (Meishan), lower slope (Shangsi), and carbonate platform (Daijiagou and Liangfengya) settings. Constrained by the latest high-precision geochronological dates and high-resolution conodont biozones, we can establish the temporal and spatial patterns of seawater temperature changes and assess their potential connections with the carbon cycle disruption and biodiversity decline. We find a rapid warming of~10°C during the latest Permian-earliest Triassic that postdated the onset of the negative shift in δ 13 C carb by~81 kyr (thousand years), the abrupt decline in δ 13 C carb by~32 kyr and the onset of mass extinction by~23 kyr, which contradicts previous claims that the extreme temperature rise started immediately before or coincided with the onset of mass extinction. Our new evidence indicates that climate warming was most likely not a direct cause for the main pulse of the end-Permian mass extinction (EPME), but rather a later participant or a catalyst that increased the pace of the biodiversity decline. In addition, a prominent cooling is recorded in the earliest Changhsingian, with the main phase (a drop of~8°C in~0.2 Ma) confined to the lower part of the Clarkina wangi zone and synchronous with the positive limb of the carbon isotope excursion (CIE) around the Wuchiapingian-Changhsingian boundary (WCB) in Meishan and Shangsi. Further long-term and high-resolution studies from other sections are needed to confirm the full contexts and underlying dynamics of the WCB "cooling event".

“…Stable isotopes from various body tissues and faeces have been used in most chordate classes to investigate trophic interactions, dietary preferences and seasonal dietary shifts . However, repeated time‐sequenced analyses of focal animals are not common and measurement techniques are often invasive using tissues such as teeth, bone or muscle . Hair may provide a good alternative source of information about the physiological condition of live animals because it can be collected non‐invasively, it grows continuously, and it may retain relevant metabolites from which the chronic condition of the animal can be inferred over long periods of time .…”

RationaleNutritional bottlenecks often limit the abundance of animal populations and alter individual behaviours; however, establishing animal condition over extended periods of time using non‐invasive techniques has been a major limitation in population ecology. We test if the sequential measurement of δ15N values in a continually growing tissue, such as hair, can be used as a natural bio‐logger akin to tree rings or ice cores to provide insights into nutritional stress.MethodsNitrogen stable isotope ratios were measured by continuous‐flow isotope‐ratio mass spectrometry (IRMS) from 20 sequential segments along the tail hairs of 15 migratory wildebeest. Generalized Linear Models were used to test for variation between concurrent segments of hair from the same individual, and to compare the δ15N values of starved and non‐starved animals. Correlations between δ15N values in the hair and periods of above‐average energy demand during the annual cycle were tested using Generalized Additive Mixed Models.ResultsThe time series of nitrogen isotope ratios in the tail hair are comparable between strands from the same individual. The most likely explanation for the pattern of 15N enrichment between individuals is determined by life phase, and especially the energetic demands associated with reproduction. The mean δ15N value of starved animals was greater than that of non‐starved animals, suggesting that higher δ15N values correlate with periods of nutritional stress.ConclusionsHigh δ15N values in the tail hair of wildebeest are correlated with periods of negative energy balance, suggesting they may be used as a reliable indicator of the animal's nutritional history. This technique might be applicable to other obligate grazers. Most importantly, the sequential isotopic analysis of hair offers a continuous record of the chronic condition of wildebeest (effectively converting point data into time series) and allows researchers to establish the animal's nutritional diary.
