Demographic and growth rings data of Pentaclethra macrolona in the Amazon River estuary
<p>Little is known about the natural history of the hyperdominant Amazonian tree <em>Pentaclethra macroloba</em>. It has multiple uses and is widely explored, due to the important phytotherapy properties of the oil of its seeds. We determined the demographic and growth patterns of <em>P. macroloba</em> and analyzed the influence of the daily tide in its growth trajectory. We studied populations of <em>P. macroloba</em> in the APA and CEM, northeast of the Brazilian Amazon. In 136.59 ha of the APA, all adult trees with diameter ≥ 5 cm were quantified and two plots of 1 ha each were installed for sampling of the regeneration (diameter < 5 cm). Samples of the radial wood of 38 trees were obtained to determine age and growth rates, through dendrochronological analyzes. In CEM, exchange activity of 30 trees, at different topographic levels, was monitored by dendrometer bands. The effect of precipitation, temperature and flood on the exchange activity of <em>P. macroloba</em> was evaluated using multiple regressions. We model the growth of the species based on the widths of its growth rings. We invented 2,072 adult trees (15 individuals ha<sup>-1</sup>), distributed in 12 diametric classes (log-normal pattern), mean diameter of 23 cm, total basal area 98.13 m², height mean of 12.7 m and aggregate distribution pattern (R = 0.63, p <0.002). 240 regenerants (120 individuals ha-1) were quantified, distributed in nine diametric classes (negative exponential pattern), mean height of 0.63 m and aggregate pattern. Growth rings formed by marginal parenchyma show maximum age of 102 years and mean of 60 years for <em>P. macroloba</em>. The relationship between age and diameter was highly significant (r<sup>2</sup> = 0.98; p <0.001), as well as the relationship between height and diameter (r<sup>2</sup> = 0.79; p <0.001). The growth models show increment peaks in diameter and height at the age of 46 years (9.38 mm year<sup>-1</sup>) and 20 years (48.2 cm year<sup>-1</sup>) respectively. Greatest accumulation of biomass occurred at the age of 66 years (40.8 kg year<sup>-1</sup>). <em>P. macroloba</em> presents exchange dormancy in the rainy season (t = -2.62; p <0.01) and of river flooding (t = -3.01; p < 0.01). The existence of rings in <em>P. macroloba</em> is an important discovery, as only <em>Mora paraensis</em> had growth rings record in the Amazon estuary. The structural and growth patterns of <em>P. macroloba</em> are reflections of its life history and interactions with the environmental dynamics of estuarine floodplain.</p>
Data from: Genetic wealth, population health: major histocompatibility complex variation in captive and wild ring-tailed lemurs (Lemur catta)
Across species, diversity at the major histocompatibility complex (MHC) is critical to individual disease resistance and, hence, to population health; however, MHC diversity can be reduced in small, fragmented, or isolated populations. Given the need for comparative studies of functional genetic diversity, we investigated whether MHC diversity differs between populations which are open, that is experiencing gene flow, versus populations which are closed, that is isolated from other populations. Using the endangered ring-tailed lemur (Lemur catta) as a model, we compared two populations under long-term study: a relatively "open," wild population (n = 180) derived from Bezà Mahafaly Special Reserve, Madagascar (2003–2013) and a "closed," captive population (n = 121) derived from the Duke Lemur Center (DLC, 1980–2013) and from the Indianapolis and Cincinnati Zoos (2012). For all animals, we assessed MHC-DRB diversity and, across populations, we compared the number of unique MHC-DRB alleles and their distributions. Wild individuals possessed more MHC-DRB alleles than did captive individuals, and overall, the wild population had more unique MHC-DRB alleles that were more evenly distributed than did the captive population. Despite management efforts to maintain or increase genetic diversity in the DLC population, MHC diversity remained static from 1980 to 2010. Since 2010, however, captive-breeding efforts resulted in the MHC diversity of offspring increasing to a level commensurate with that found in wild individuals. Therefore, loss of genetic diversity in lemurs, owing to small founder populations or reduced gene flow, can be mitigated by managed breeding efforts. Quantifying MHC diversity within individuals and between populations is the necessary first step to identifying potential improvements to captive management and conservation plans.
Data from: Modelling and simulation of a thermally induced optical transparency in a dual micro-ring resonator
This paper introduces the simulation and modelling of a novel dual micro-ring resonator. The geometric configuration of the resonators, and the implementation of a simulated broadband excitation source, results in the realization of optical transparencies in the combined through port output spectrum. The 130 nm silicon on insulator rib fabrication process is adopted for the simulation of the dual-ring configuration. Two titanium nitride heaters are positioned over the coupling regions of the resonators, which can be operated independently, to control the spectral position of the optical transparency. A third heater, centrally located above the dual resonator rings, can be used to red shift the entire spectrum to a required reference resonant wavelength. The free spectral range with no heater currents applied is 4.29 nm. For a simulated heater current of 7 mA (55.7 mW heater power) applied to one of the through coupling heaters, the optical transparency exhibits a red shift of 1.79 nm from the reference resonant wavelength. The ring-to-ring separation of approximately 900 nm means that it can be assumed that there is a zero ring-to-ring coupling field in this model. This novel arrangement has potential applications as a gas mass airflow sensor or a gas species identification sensor.
Data from: Inter-individual spacing affects the finder's share in ring-tailed coatis (Nasua nasua)
<p>Social foraging models are often used to explain how group size can affect an individual's food intake rate and foraging strategies. The proportion of food eaten before the arrival of conspecifics, the finder's share, is hypothesized to play a major role in shaping group geometry, foraging strategy, and feeding competition. The variables which affect the finder's share in ring-tailed coatis were tested using a series of food trials. The number of grapes in the food trials had a strong negative effect on the finder's share and the probability that the finder was joined. The effect of group size on the finder's share and foraging success was not straightforward, and was mediated by socio-spatial factors. The finder's share increased when the time to arrival of the next individual was longer, the group was more spread out, and the finder was in the back of the group. Similarly, the total amount of food eaten at a trial was higher when more grapes were placed, arrival time was longer, and number of joiners was smaller. Individuals at the front edge of the group found far more food trials, but foraging success was higher at the back of the group where there were fewer conspecifics to join them. This study highlights the importance of social spacing strategies and group geometry on animal foraging tactics and the costs and benefits of sociality.</p>
Lemanaghan Ringed Cross-Slab (OF015-004018-)
Early Christian ringed cross-slab now attached to the internal face of the eastern gable of the Romanesque Church ruins (OF015-004003-) at Lemanaghan Monastery, County Offaly. A free-standing ringed-cross with sunken quadrants contained within a circular-shaped frame has been incised into a small sandstone slab. A monastery at Lemanaghan (Liath Manchán) was founded in the 7th century by Manchán whose feastday is celebrated on the 24th of January.

Cloanlawyers 2 - Cup & Ring Marked Rock
This rock was Rock no.2 of Richard Bradley's excavations at Cloanlawers from 2007-2010. The ScRAP team uncovered this again last week for possibly only the second time. The markings are on a large schist oucrop, which lies at the 400 metre contour on a SE facing slope overlooking Loch Tay. The outcrop is shaped like a large sofa, with the most intricate carvings on the inside of the 'right arm and on the adjacent basin below at the left hand side and to the front of the 'seat'. These consist of a number of cup and multiple ring markings - some with circular rings, others with interconnected rings. Visible on the model are two striking cup marks surrounded by a figure-of-eight created by their rings. Another cup and multiple ring mark with a radial is prominent and the more you look, the more you see. Grid Ref.

Late 19th Century Ring
This ring was found by CAP during some excavations in 2015 and dates to the late 19th century. The ring is around a size 7.5 and has since lost the gem although the setting for it it easily seen. Women were first able to enroll at MSU (then called State Agricultural College) in 1870. This ring dates to sometime around or after that, making it one of the earliest artifacts found by CAP that directly ties females to the university. This is espcially meaningful since women's movement around campus was restricted. This model was created by Jack A. Biggs using Agisoft Metashape. Source: Objaverse 1.0 / Sketchfab
Allt Coire Phadairlidh 5 - Cup & Ring Marked Sto
This very weathered stone lies on the 470 metre contour on a SE facing slope above Loch Tay beneath Meall Greigh just above the bank of a small burn & immediately adjacent to another cup & ring marked stone. It is made of schist and is extremely weathered due to exposed position. However, it may once have been intensively decorated with cup & ring marks. We counted 36 cup marks in the field, with 4 to 5 of these having rings but these are now very difficult to discern.
