Summary: The study investigates the impact of political connections on the cash flows and firm investments of Indian firms. Using data from 1,953 listed firms on the National Stock Exchange during the period of 2009 to 2021, the study finds that politically connected firms have lower investment cash flow sensitivities compared to politically non-connected firms. Additionally, politically connected, financially constrained firms are less reliant on internal cash for investments.

Summary: This study used historical demographic analysis and comparative phylogeography to assess the past connections between Amazonia and the Atlantic Forest and their impact on the formation and divergence of avian populations in the Atlantic Forest. The results showed that past humid periods facilitated contact and migration flows between the two regions. Population divergences occurred multiple times during the Pleistocene and were associated with climate-driven habitat shifts.

Summary: Understanding the genetic structure and diversity of insect vectors is crucial for disease epidemiology. This study used mitochondrial cytochrome c oxidase I sequences to infer the genetic diversity, structure, and population history of the black fly Simulium chumpornense Takaoka and Kuvangkadilok, a suspected vector of blood protozoa. The results showed high intraspecific genetic divergence and revealed two genetic lineages that were geographically associated. The population pairwise F-ST analysis indicated significant genetic differences among almost all population comparisons, suggesting a high level of genetic structuring possibly due to historical isolation during glaciations.

Summary: Madagascar's unique fauna has attracted attention for a long time. It is believed that most land animals reached the island through over-water dispersal. The previous notion of land bridges connecting Africa and Madagascar in the Cenozoic has been discredited, as only a few supposed dry-land sub-paths were actually land.

Summary: The drainage integration of three Late Pleistocene intramontane basins located in the southern Italian Apennines was reconstructed by integrating information derived from geomorphic, structural, and stratigraphic analyses. These basins were primarily formed by tectonic and climatic controls, including the formation of troughs and synclinal folds from NW-SE- and NE-SW-trending faults, and subsequent integration via overspill from lacustrine basins due to late Pleistocene climatic changes. This study demonstrates the complex interplay between tectonics and climate change for intramontane basin development and its drainage evolution.

Summary: The study found various metabolites in Thai dairy cow feed samples, mainly fungal and plant metabolites. Major mycotoxins such as zearalenone and fumonisins were frequently detected in concentrate and mixed feed samples, while other metabolites from Aspergillus, Fusarium, Penicillium, and Alternaria species were also present in the samples. The co-contamination of mycotoxins in feed samples should be continuously monitored to ensure food safety.

Summary: Studying the isotopic composition of dinosaur teeth provides insights into the trophic structure of Late Cretaceous food webs. The research indicates that different dinosaur species had different isotopic compositions, suggesting niche partitioning among them. Furthermore, the isotopic values of tyrannosaurids suggest that they may have preferred to feed on hadrosaurids.

Summary: Fitness-related traits have low heritabilities, while morphology tends to be highly heritable. Although many performance traits depend critically on morphology, the relationship between morphology and traits like bite force may vary within species. In this study, it was found that bite force showed undetectable additive genetic variance and heritability, suggesting it is less responsive to selection compared to its morphological determinants.

Summary: Histological and morphological studies were conducted on osteoderms from eight extant and extinct species of crocodylomorphs. Most osteoderms exhibited a typical crocodilian structure, while an osteoderm of Iberosuchus was found to be nearly devoid of ornamentation and had a unique structure. This suggests a possible link to terrestrial ecology and specific thermoregulation strategies. The findings were discussed in light of current interpretations of osteoderm function(s) in crocodilians and the ecophysiological peculiarities of Notosuchia, particularly Iberosuchus.

Summary: We described the endocranial structures of Hamadasuchus, a crocodylomorph from Morocco, and compared them with other crocodylomorphs. The study identified the cranial bones of Hamadasuchus and explored its paleobiological traits for the first time. The expanded but narrow semi-circular canals and enlarged pneumatization of the skull suggest a terrestrial lifestyle. Further research on the neuroanatomy of terrestrial crocodylomorphs is needed to understand the impact of lifestyle on internal structures.

Summary: A new mandibular fossil assignable to Hamadasuchus cf. rebouli from Algeria is described in this study, which is an extinct terrestrial crocodylomorph from the Cretaceous of Africa and South America. The study shows that mandibular characters commonly used to differentiate between closely related crocodylomorph taxa actually record intra-specific or ontogenetic variability. Reliable mandibular characters enable us to propose a reduction in the taxonomic content of Hamadasuchus rebouli, and highlight the importance of mandibular characters in phylogenies.

Summary: The post-K-Pg boundary continental ecosystems of Europe have a unique assemblage of derived neosuchians, including the alligatoroid Diplocynodon, the crocodyloid Asiatosuchus, and the lesser-known group called the Planocraniidae. Europe also preserves some of the last representatives of Notosuchia, a group that previously had a successful radiation in terrestrial ecosystems of the Cretaceous. The discovery of a new sebecosuchian species, Dentaneosuchus crassiproratus, in southern France sheds light on the phylogenetic position of these species and their status as apex predators in Europe and South America.
