title: Above ground carbon stock mapping over Coimbatore and Nilgiris Biosphere: a key source to the C sink

description: Mapping and quantifying above ground carbon (AGC) Stocks reflect significant dynamics in the terrestrial carbon cycle and cascade climate change. Estimation of such key driver was performed for the dominant species (Bamboo, Eucalyptus and Teak) over Coimbatore and Nilgiris Biosphere (2006 − 2018 quadruple interval) of Tamilnadu, India with the developed global stepwise multiple linear regression (SMLR) and local geographically weighted regression (GWR) models using multi-dynamic variables. Evapotranspiration (ET) developed using Mapping Evapotranspiration at High Resolution with Internalized Calibration (METRIC) model for the region was analysed with the best-fitted AGC estimation model to understand AGC—ET synergistic pertinence dynamics. The study compared and validated the estimation by the models and indicated that AGC estimation using SMLR exhibiting a high degree of accuracy (R2=0.84, RMSE=5.67, MAE=4.61 Mg ha−1) with nominal negative bias in the estimation ranging from 0.13−146.34 Mg ha−1 with amplification of 1.87±1.2% year−4. GWR prediction indicted positive bias with comparatively least mean accuracy (R2=0.59, RMSE=13.72, MAE=12.85 Mg ha−1). The ET—AGC reciprocity for the dominant species resulted that, bamboo with lower AGC ∼25 Mg ha−1 correlated with higher ET ∼3 mm day−1 tailed by teak with higher AGC ∼45 Mg ha−1 and ET ∼2.5 mm day−1 and eucalyptus with relatively higher AGC and lower ET ∼50 Mg ha−1 and ∼3 mm day−1, respectively. The analysis resulted in minimal biasness in AGC mapping using SMLR, and both the model signifies that the region can potentially be considered a long-term carbon sink.

title: The evolution of asymmetry in Upper Cretaceous <i>Cyclothyris</i> (Brachiopoda, Rhynchonellida)

description: The study of Upper Cretaceous <i>Cyclothyris</i> from Spain and the revision of asymmetrical rhynchonellides from numerous European collections have led to improve some systematical, biostratigraphical and palaeobiogeographical questions, allowing to update taxonomically this group. The species studied here are the following: <i>Cyclothyris difformis</i> (Valenciennes in Lamarck, 1819); <i>Cyclothyris nekvasilovae</i> sp. nov.; <i>Cyclothyris</i>? <i>contorta</i>? (d’Orbigny, 1847); <i>Cyclothyris zahalkai</i> Nekvasilová, 1973; <i>Cyclothyris segurai</i> Berrocal-Casero, 2020; <i>Cyclothyris cardiatelia</i> Berrocal-Casero, 2020; <i>Cyclothyris claudicans</i> (Coquand, 1879); <i>Cyclothyris globata</i> (Arnaud, 1877); and <i>Cyclothyris</i>? <i>vesicularis</i> (Coquand, 1860). Starting from the preliminary interpretation about the functional meaning of the asymmetry in <i>C. cardiatelia</i>, a hypothesis about the origin of the obligate asymmetry in Upper Cretaceous <i>Cyclothyris</i> has been proposed here, which implies a phylogenetic relationship between <i>C. segurai, C. cardiatelia, C. globata</i> and, possibly, <i>C</i>.? <i>vesicularis</i>.

title: Taphonomic assessment of material generated by an Arboreal Nesting Colony of Great Blue Herons (<i>Ardea herodias</i>)

description: Reports on nesting debris generated by great blue heron (<i>Ardea herodias</i>), arboreal nesting birds with ‘semi-altricial’ young, are limited. In this study, surface and subsurface sampling were conducted in 2012 and 2013 in a heronry near the Missouri River in Montana, including bi-weekly collections in 2013 documenting accumulations over the breeding season. Disarticulated juvenile heron bones with lesser numbers of microvertebrates (fish and small mammals) and invertebrates (crayfish and snails) dominated the assemblage beneath the nests. Eggshell on the surface was present but uncommon (0.85 eggshells/m<sup>2</sup>) with eggshell orientation varying both by location and fragment size. Eggshell surveys differed with respect to sampled trees and sampling time, but generally favoured concave-up orientation whereas the early season small eggshell survey further from sampled trees favoured concave down. Shallow (10 cm deep) excavation revealed a subsurface assemblage very similar to that on the surface but favouring more resistant elements. Hence, the subsurface assemblage was nearly devoid of eggshell, with a lower representation of invertebrates and fragile bone, but an excess of heron hindlimbs. Our study demonstrates that arboreal nesting sites have the potential for long-term preservation and provides information useful for recognition and reconstruction of arboreal nesting sites from the fossil record.

title: Fish fossils of Taiwan: a review and prospection

description: Despite the frequent occurrence of fish fossils in the field, related studies are noticeably rare in Taiwan. The scant fossil record of fish in the literature sharply contrasts the high diversity of modern fish in this region. This is often due to the scarcity of well-preserved materials, limited exposure that covers long geological ages, and lack of comprehensive sampling design. Over the years, unstudied new fish fossils have been collected and accumulated. Several old and published specimens stored in private collections are lost. In this study, we evaluated potential horizons yielding fish fossils, examined the current status of published specimens with updated regional stratigraphic correlation, and finally explored possible directions for future work. Our extensive bibliographic reviews revealed a total of published 47 taxa, which are mostly in the form of teeth (elasmobranch) and otoliths (teleost). Skeletal specimens with taxonomic value are rare. Using Plio-Pleistocene otoliths from the famous Chochen-Tsailiao locality, we further demonstrated that they are numerous in the sediments, with high abundance and broad distribution. Study small fish remains for attaining a high resolution on the spatiotemporal dynamics of fish faunas through time and for providing the data necessary for conservational purposes is recommended.

title: A new throscid from mid-Cretaceous Burmese amber (Coleoptera: Elateroidea: Throscidae)

description: Throscidae is a small family belonging to the polyphagan superfamily Elateroidea. Fossil throscids with a large morphological variety have been discovered from Cretaceous and Cenozoic amber deposits. However, only one of them has been reported from the fossil-rich Cretaceous Burmese amber so far. Here we describe and figure the second throscid beetle in mid-Cretaceous Burmese amber (ca. 99 Ma), <i>Trixagosoma guangyuani</i> gen. et sp. nov. The new fossil species has <i>Trixagus</i>-like short mesotarsal grooves and <i>Potergosoma</i>-like prosternum with nonparallel carinae. Our phylogenetic analysis indicates that it represents an early branching lineage of Throscidae. Its short mesotarsal grooves on metaventrite might represent an early evolutionary stage of this structure. http://zoobank.org/urn:lsid:zoobank.org:pub:2793C1A1-EE55-4F96-B3E8-E98D289EB261

title: Quaternary sigmodontines (Mammalia, Rodentia) from Serra da Bodoquena, Mato Grosso do Sul, Brazil

description: Sigmodontine rodents are extremely diversified in the Neotropics but their fossil record remains generally poorly known, especially in Brazil. Here, we examine the assemblage of sigmodontines from the limestone cave Nossa Senhora Aparecida (21°5ʹ27.89”S 56°34ʹ28.77”W), located in Serra da Bodoquena (Mato Grosso do Sul), a karstic region in southwestern Brazil. We describe cranial and dental fragments and recognise the presence of some new species not previously recorded for the region, as <i>Bibimys</i> sp., <i>Graomys</i> cf. <i>G. chacoensis, Thalpomys lasiotis</i>, and <i>Pseudoryzomys simplex</i>. This fossil assemblage is comparable to others fossil sites in Brazil, such as those from Goiás and Rio Grande do Sul, with the predominance of species from open areas, including grasslands, and some of forested environments from Cerrado landscapes.

title: A revision of the poorly known Pontocaspian gastropod genus <i>Abeskunus</i>, and its Central Paratethyan origin

description: Biodiversity and conservation assessments rise and fall with taxonomic accuracy. An example of a still largely unresolved taxonomy is found in the Gastropoda of the Caspian Sea. The present paper clarifies the taxonomy of the genus <i>Abeskunus</i> and its three species of anomalohaline gastropods endemic to the Caspian Sea. Based on material from Pleistocene, Holocene, and (sub-)recent deposits from Russia, Azerbaijan, and Kazakhstan we discuss species discriminations, synonyms, systematic position, as well as uncertainties regarding the type species. Given the apparent loss of all type material, we designate neotypes for all three species. Despite our efforts to collect and analyse new material and available material housed in museum collections, molecular data, and soft-part anatomy are unavailable precluding a firm systematic classification. Overall shell morphology and protoconch microsculpture are indicative of the family Lithoglyphidae. Comparison with Miocene and Pliocene fossils attributed to the genus <i>Zagrabica</i> suggests it to be a likely ancestor of <i>Abeskunus</i>, tracing back the lineage to the late Miocene Lake Pannon. Although the recent literature lists all three species of <i>Abeskunus</i> among the extant Pontocaspian fauna, two of the three species have never been found living and the third one not since the nineteenth century.

title: Archival data provides insights into the ambiguous track-maker gait from the Lower Jurassic (Sinemurian) Razorback beds, Queensland, Australia: evidence of theropod quadrupedalism?

description: The ichnological and palaeobiological interpretation of the first dinosaur tracks described from the Lower Jurassic (Sinemurian) Razorback beds, anthropogenic ‘fireclay caverns’ of Mount Morgan, Australia, is reviewed. This track sequence of two size categories has been widely accepted as having been formed by a theropod walking in an uncharacteristic quadrupedal stance. However, the morphology of the purported manus impression remained ambiguous due to the poor reproduction quality of the original image data. Here, we present previously unpublished archival photographic and replica material of this track surface. These clearly show the morphological details of the track series that are consistent with registration by two different sized bipedal track-makers. Overall, our findings illustrate that retained archival data can be pivotal in the resolution of palaeoichnological obscurities.

title: Tribal allocation and biogeographical significance of one of the largest sigmodontine rodent, the extinct Galápagos <i>Megaoryzomys</i> (Cricetidae)

description: One of the largest members of Sigmodontinae, the extinct <i>Megaoryzomys curioi</i> from Santa Cruz Island in the Galápagos Archipelago (Ecuador), is traditionally treated as a representative of Thomasomyini. We contrasted this hypothesis based on a direct study of craniodental material of <i>M. curioi</i>, including a well-preserved skull assessed through CT-scan examination, within a broader sampling of brachydonts sigmodontines. <i>M. curioi</i> lacks or presents a poorly expressed suspensory process of the squamosal bone, while in Thomasomyini this structure is well developed. In the same way, <i>M. curioi</i> does not exhibit the condition in the dorsal aperture of the ectotympanic displayed by the Thomasomyini, and the morphology of the mandible also contrasts with the widespread condition shown by Thomasomyini. Besides, the procingulum of the first lower molar in <i>M. curioi</i> lacks the typical pattern of Thomasomyini composed of two defined conulids. Overall craniodental morphology in <i>M. curioi</i> favours its allocation to the Oryzomyini. This alternative hypothesis resolves two biogeographical issues connected with the target genus: (1) Galápagos Islands were colonised by members of a single sigmodontine tribe (i.e., Oryzomyini) and (2) within the sigmodontine radiation; members of the Oryzomyini were uniquely capable of reaching oceanic islands.
