Ant–plant relationships in the canopy of an Amazonian rainforest: the presence of an ant mosaic
-
Using different techniques to access the canopy of an Amazonian rainforest, we inspected 157 tree crowns for arboreal ants. Diversity statistics showed that our study sample was not representative of the tree and ant populations due to their high diversity in Amazonian rainforests, but permitted us to note that a representative part of territorially dominant arboreal ant species (TDAAs) was inventoried. Mapping of TDAA territories and use of a null model showed the presence of an ant mosaic in the upper canopy, but this was not the case in the sub-canopy. Among the TDAAs, carton-nesting Azteca dominated (52.98% of the trees) whereas ant-garden ants (Camponotus femoratus and Crematogaster levior), common in pioneer formations, were secondarily abundant (21.64% of the trees), and the remaining 25.37% of trees sheltered one of 11 other TDAAs. The distribution of the trees forming the upper canopy influences the structure of the ant mosaic, which is related to the attractiveness of some tree taxa for certain arboreal ant species and represents a case of diffuse coevolution.

Anthropology: Pediatric and Juvenile.

he death of a fetus or child due to maltreatment raises many forensic as well as physiological issues. Forensic anthropological techniques using medical imaging of bones are very useful in analyzing the sequelae in physical child maltreatment[note that there are over recent years several terms and expressions to explain the results of physical child trauma: non-accidental trauma (NAT) or nonaccidental injury (NAI); suspected child physical abuse (SPA); inflicted injury (II); battered child syndrome; abusive head trauma of “shaken baby syndrome”(Bhattacharya et al., 2023; Paddock et al., 2017a)]. In infanticide and fetus death, anthropological characteristics and clinical parameters of age estimation are also of high importance. The contribution of forensic anthropology to the pathologist’s examination is of fundamental importance. The fields of forensic anthropology and bioarcheology are complicated and requires a multidisciplinary approach.

Antibodies against medically relevant arthropod-borne viruses in the ubiquitous African rodent Mastomys natalensis
-
Author summary One of the main causes of zoonotic related human morbidity and mortality is the transmission of arthropod-borne viruses such as dengue virus, Yellow Fever virus, and chikungunya virus. These viruses cannot only infect humans but also livestock, pets, and wildlife, though our understanding of their non-human hosts remains limited. Rodents are thought to be an important host for these viruses because they can be abundant, often live near humans, and some are already known to be viral hosts. However, research has focused mostly on non-human primates, neglecting other potential wild hosts. To address this gap, we have developed a high-throughput antibody test to screen rodent blood against 15 different arboviruses. Our findings reveal that Mastomys natalensis, a common African rodent species, carries antibodies that (cross-)react against these viruses. We hypothesize that immunologically naïve juveniles may drive transmission, particularly during population outbreaks. These outbreaks coincide with environmental conditions that are favorable for mosquitoes, thus increasing the risk of spillover to humans, livestock, and wildlife. Understanding the role of rodents in arbovirus transmission dynamics is crucial for mitigating zoonotic disease risks.

Anurans of In Becetèn (Republic of Niger): the most diverse site for amphibians in Mesozoic Africa
-
In Becetèn (Niger) represents one of the most diverse continental vertebrate faunas from the Late Cretaceous of Africa. Recently, anurans, in particular aquatic pipimorphs, have generated renewed interest, with the identification of four distinct pipimorph taxa. Here we describe the remaining anuran specimens from In Becetèn, which represent at least three new anuran taxa that cannot be assigned to pipimorphs (Anura indet, Neobatrachia and a ranoid). Among them, one taxon, documented by ornamented cranial material, is a large Neobatrachia incertae sedis, as suggested by our phylogenetic analyses. This marks only the third Mesozoic occurrence of neobatrachians in Africa. In addition, an isolated humerus is referred as a new unnamed ranoid and is not only the oldest known occurrence of the clade, but also the first known Mesozoic specimen of this cosmopolitan family from Africa. With at least seven anuran taxa identified, In Becetèn is the most diverse locality of Africa, and one of the most diverse localities across the Late Cretaceous (Coniacian or Santonian).
