“…This was also evident from the mitotype network, which showed mostly single-nucleotide differences between mitotypes within the species ( Figure 13 ). Such a contradiction has been often observed during other mitochondrial DNA studies of insects [ 32 , 49 , 50 , 51 ], crustaceans [ 52 ], molluscs [ 53 ], fish [ 54 , 55 ], mammals [ 56 ], etc., and such mitotype and nucleotide diversity combination is characteristic of populations that have expanded over a relatively short period of time from a small effective population size to their currently inhabited areas [ 57 ]; this assumption was approved by the Tajima‘s D, Fu and Li‘s D, Fu and Li‘s F neutrality tests in the case of S. plagicolella . Unlike some other Lepidoptera (e.g., [ 58 ]), we suppose that pygmy leaf-mining moths are weak flyers and do not migrate; therefore, their rapid expansion might be related to the human-assisted transportation of their host plants.…”

In instances of severe infestations, Nepticulidae larvae can inflict damage on cultivated plants. Previously, it was assumed that the Prunus-feeding Nepticulidae have continuous distribution from Europe to the neighboring Caucasus. During recent fieldwork in the Caucasus, leaf mines were found on plum trees that initially resembled those of Stigmella plagicolella (Stainton) in Europe. However, upon rearing the adults, significant differences emerged, leading to the hypothesis that a different Prunus-feeding species exists in the Caucasus; this challenges previous records in Western Asia. This paper presents the outcomes of our morphological, molecular, and statistical investigations, unveiling S. colchica sp. nov., a previously unknown potential plum-tree pest. Distinguished by male genitalia characteristics, the new species differs from S. plagicolella. The inter- and intraspecific divergences between S. colchica sp. nov. and S. plagicolella range from 3.5% to 6.02%. Moreover, the utilized delimitation algorithms reliably clustered two species separately, as does our mitotype network. A statistical analysis also shows a discernible trend between the leaf mines of S. colchica sp. nov. and S. plagicolella. This unexpected discovery not only documents a new potential pest, enhancing our understanding of the Caucasian fauna, but also contributes to the broader biological inventory.

“…However, other scenarios exist for this pattern of nucleotide and haplotype diversities, including the subjection of species to overexploitation and habitat destruction. This was suggested for several other species of shrimps around the world, including for example the pink shrimp Farfantepenaeus paulensis (Pérez Farfante, 1967) in the south-southeastern coast of Brazil (Teodoro et al, 2020) and the Indian prawn Fenneropenaeus indicus (H. Milne Edwards, 1837) in the Tanzanian coastal waters (Mwakosya et al, 2018). In all cases, these may represent signs of the necessity of more serious investigation of species state of conservation and application of through stock surveillance management strategies.…”

The green tiger prawn Penaeus semisulcatus is one of the major commercial trawl crustaceans in the Red Sea, the Arabian Gulf, and the Indian Ocean. Herein, we aimed to assess its genetic diversity and phylogeographic criteria in the North West (NW) of the Red Sea. Prawn samples were collected from the Bitter Lakes; the North; and the South of the Gulf of Suez in Egypt. The hypervariable, 5´ barcode area of the Cytochrome oxidase subunit 1 (COI) gene was PCR-amplified and sequenced in all samples. The resulting sequences were subjected to several genetic, phylogenetic, and population genetics' analyses. Consequently, clear signs of genetic populations’ diversity, expansion; and possible structuring were identified in different areas in the NW Red Sea. Furthermore, extremely discordant genetic connectivity was found between the populations around the Arabian Plate (i.e. of the Red Sea and Strait of Hormuz) and the IndoWest Pacific, resulting in characterizing the Arabian plate populations as a separate lineage of P. semisulcatus. Based on these findings, it is important to investigate whether there are other discriminative genomic, morphological and/or morphometric differences among the genetically identified lineages and populations. Consequently, differential conservational strategies of different populations of this species should be applied in the studied areas.

“…An increase in industrial as well as artisanal estuarine fishing, combined with low effectiveness of fishing legislation, led to the collapse of pink shrimp Farfantepenaeus spp. stocks in the late 1990s (D’Incao et al, 2002; Teodoro et al, 2019). Consequently, the seabob shrimp Xiphopenaeus kroyeri (Heller, 1862) became the main target of fishing on the southeastern Brazilian coast (Costa et al, 2007; Simões et al, 2010).…”

We investigated and compared growth parameters, longevity, mortality (total, natural, and fishing), and exploitation rates of the seabob shrimp Xiphopenaeus spp. in four important fishing regions of southeastern Brazil. The hypothesis that the growth and mortality characteristics of distinct populations differ along a latitudinal gradient was tested. Sampling was performed monthly in Macaé, Ubatuba, Santos/São Vicente, and Cananéia over a 1‐ to 2‐year period. Growth and longevity parameters were estimated by the von Bertalanffy growth equation models. Total mortality (Z) was estimated by length‐converted catch curves. Growth parameters differed between sexes: males reached smaller sizes, showed larger growth coefficients (k) and higher mortality, and lived less than females in the four studied regions. Rather than finding a latitudinal gradient, our results support the hypothesis that distinct local environmental characteristics and fishing pressures alter the growth and population dynamics of Xiphopenaeus spp. in different areas. Our study indicates that the stocks of Xiphopenaeus spp. are overexploited, highlighting the importance of management plans to prevent the collapse of stocks and maintain them at sustainable levels for long‐term exploitation.
