On The Occurrence Of Two Lessepsian Fishes In The Southern Tyrrhenian Sea: Filefish Stephanolepis Diaspros And Goatfish Upeneus Pori, Carlo Pipitone, Fabio Badalamenti, Giovanni D'Anna, Giuseppe Di Stefano, Arturo Zenone

Turkish Journal of Zoology

The reticulated leatherjacket Stephanolepis diaspros and the Por’s goatfish Upeneus pori occur as lessepsian migrants in the eastern and central Mediterranean Sea. This article reports about the findings of one reticulated leatherjacket and two Por’s goatfishes in the Gulf of Castellammare, southern Tyrrhenian Sea, which suggest a possible westbound expansion of the Mediterranean distribution for the latter species. The specimens were three adults collected by professional fishermen on inshore sandy bottoms with a trammel net. The main meristic characters of both species, the identification issues in S. diaspros and the potential impact of U. pori on the native biota and …

Determination Of Spermatogenesis Activity Using Lectin Histochemistry In Water Monitorlizards (Varanus Salvator) Harvested From The Wild, Andhika Yudha Prawira, Ni Luh Putu Rischa Phadmacanty, Gono Semiadi, Hellen Kurniati, Wahyu Trilaksono, Nurhidayat Nurhidayat, Savitri Novelina

Turkish Journal of Zoology

Lectin is often used to investigate the differentiation and maturation of spermatogenic cells in the testes of several wild animals, facilitating the screening of mature individuals. Therefore, this study aimed to determine spermatogenesis activity using lectin histochemistry in water monitor lizards harvested from the wild. Testes of 43 comprehensively examined water monitor lizards (Varanus salvator) were collected from slaughterhouses in Palembang (Sumatra) and Banten (West Java), Indonesia, with Snout-Vent Length (SVL) ranging from 39 to 96 cm. Additionally, histologic, histomorphometric, Periodic Acid-Schiff (PAS) staining, and lectin histochemistry (Con A, RCA, WGA, PNA, VVA, DBA, UAE-I) observations were performed. The results …

Not Just Any Tree: The Influence Of Leaf Characteristics On The Nest Site Selection Ofasian Weaver Ants, Amira Aqilah Muhammad, Noorhidayah Mamat, Kien-Thai Yong, Nurul Ashikin Abdullah

Turkish Journal of Zoology

The connection between plant species and nest site preference for the Asian weaver ant Oecophylla smaragdina remainspoorly understood despite their common occurrence in the urban areas of tropical regions. We predicted that plant species with specificleaf characteristics influence the nesting preference of Asian weaver ants, given that plant foliage is the main component of their neststructure. We studied the leaf characteristics of the tree species in which their nests were detected, including leaf shape, leaf apex shape,and leaf arrangement. Of the 206 total trees among the 20 tree species sampled, 185 trees from 18 tree species had at least one …

The Impact Of Cervid Herbivory On Industrial Fiber Hemp In East Central Illinois, Nicholas C. Cheney, Isaac Slaven, Barbara S. Carlsward

Journal of Agricultural Hemp Research

The last several years have seen large increases in white-tailed deer populations across the United States. Many studies have analyzed the effects that white-tailed deer have on different ecosystems. However, little to no studies have analyzed the effects of white-tailed deer on the production of industrial hemp fiber. In this study, we examined two different varieties of hemp fiber crops, and the impact white-tailed deer may have on their production. Our study was conducted in a flat test plot with surrounding woods and known white-tailed deer traffic in central Illinois, using two (6 × 6 m) plots that were adjacent …

A Long-Recognized But Undescribed New Species Of Cyprinella (Cypriniformes: Leuciscidae) From North Carolina And South Carolina, United States, Bryn H. Tracy, Fred C. Rohde, Michael A. Perkins, Laura M. Lee, Kara B. Carlson, Madelyn Mccutcheon, Brena K. Jones, Heather K. Evans

Southeastern Fishes Council Proceedings

Cyprinella leptocheilus sp. nov., Siouan Thinlip Chub, is described as a new species that is endemic to Sand Hills and upper Coastal Plain streams in North Carolina and South Carolina. Recognized as an undescribed species since the early 1970s, this fish was known in the literature and in museum electronic databases as Hybopsis n. sp., H. sp. cf. zanema, Cyprinella n. sp., and C. sp. cf. zanema. Unofficially, it had gone by the common name Thinlip Chub. It was thought to be closely related to the two other barbeled Cyprinella species: Thicklip Chub, …

Clustered Setation On The Pedipalps Of Buthid Scorpions (Scorpiones: Buthidae), Graeme Lowe, Victoria Tang

Euscorpius

Chaetotaxy of the external pedipalp femur and distal ventral pedipalp movable finger was studied in 120 species, 69 genera and 17 families of scorpions. Setation was generally denser in the ‘Buthus’ group, a major arid-adapted buthid lineage distributed across Palearctic deserts. On the external femur, macrosetae formed a prominent cluster, the ‘distal external macrosetal cluster’ (DEMC); on the distal ventral movable finger they formed a dense patch, the ‘distal ventral macrosetal cluster’ (DVMC). In other buthids and non-buthids, the DEMC and DVMC were mostly absent, except in a few arid-adapted genera. Relative setation densities of DEMC and DVMC in different …

Temperature Affects Nest Box Selection, Nest Success, And Nestling Size In A Southeastern Population Of Eastern Bluebirds, Katie Stumpf

Georgia Journal of Science

Given the critical role of temperature in avian reproduction, rising global temperatures will likely impact reproductive success of many bird populations. We examined the effect of nest box temperature, nest box color, entrance orientation, distance to forest cover, and distance to water on net box selection, nest success, and nestling size in eastern bluebirds (Sialia sialis) in central Georgia. White painted nest boxes had significantly cooler temperatures than control nest boxes (P < 0.05). However, model selection revealed that eastern bluebird females selected control boxes, despite their overall warmer temperatures. Nest success was associated with year, likely because of high nest predation during the warmer 2022 breeding season (P < 0.05). Nest success was also associated with cooler nest boxes, possibly because incubating females spend more time incubating which can reduce predation risks. Larger nestlings fledged from painted nest boxes, nest boxes with cooler temperatures, and nests from 2021, which we attribute to decreased thermoregulatory demands enabling faster nestling growth in cooler boxes and years. These seemingly opposing results suggest there may be an optimal temperature range where nest box temperature maximizes reproductive fitness while minimizing energetic demands on incubating adults. Determining this temperature range can help target management efforts to ensure specific goals are met.

Albinism In Olivierus Martensii (Karsch, 1879) (Scorpiones: Buthidae), Victoria Tang, Zhenbang Liu

Euscorpius

This is a formal case report for the albinism in Olivierus martensii (Karsch, 1879). Albino phenotype is compared with its normal counterpart in terms of their morphology and behavior by cursory experiments. The examined 7 albino individuals (5 of which were adults) were smaller and more slender than their normal counterparts. However, these quantitative differences were not statistically significant and should be treated with caution due to the low sample size. Their abilities to detect both white light and UV light or UV-excited fluorescence were not significantly undermined, although their tendency to ensure a clear vision through self-cleaning behavior appeared …
