A key and distribution map of Buthus in the Horn of Africa (six species) are included


More Equal Than Others: Taxonomic Bias In Animal Management, Barrett L. Christie 2025 South Carolina Aquarium

More Equal Than Others: Taxonomic Bias In Animal Management, Barrett L. Christie

Animal Sentience

Oldfield & Bonano (2024) point out not only the scarcity of research on fish welfare but also significant taxonomic bias in broader research on these species. This bias extends to the management practices of aquaria and zoos, where the focus is on higher vertebrates. More resources need to be allocated to research to address this disparity. We also need to develop welfare constructs that recognize the inherent differences between aquatic and terrestrial species, taking into account the unique ecological contexts and behavioral patterns of fishes.


Changes In Morphology, Phenology, And Demography Of Several Avian Species Over 18 Years At A Restored Grassland, Ashley McMahon, Katie Stumpf 2025 Georgia College & State University

Changes In Morphology, Phenology, And Demography Of Several Avian Species Over 18 Years At A Restored Grassland, Ashley Mcmahon, Katie Stumpf

Georgia Journal of Science

In response to a changing climate and the loss of habitat, avian species are displaying changes in body size, migration phenology, and demography. Several species have adhered to Allen’s and Bergmann’s rules by displaying increased wing length and decreased mass, respectively, over time in response to higher temperatures. Climate change has also resulted in earlier spring migration and depending on species, either earlier or later fall migration. Finally, species affected by habitat loss often display male-skewed sex ratios and juvenile skewed age ratios. Our goal was to determine how body size, migration phenology, and demography have changed for grassland birds …

Spring Field Report, March–May 2025, W. Ross Silcock 2025 Nebraska Ornithologists' Union

Spring Field Report, March–May 2025, W. Ross Silcock

Nebraska Bird Review

Perhaps the most important takeaway this spring is the continuing phenomenon of large numbers of species with early spring arrival dates. Although about half as many as 2024, there were 64 examples of either tied or new early arrival dates, most obviously of insectivores such as swifts, flycatchers, vireos, swallows, pipits, longspurs, and 10 warbler species. Among these, record or near-record early were Whip-poor-will, Black-necked Stilt, Marbled Godwit, Black Tern, Olive-sided Flycatcher, Purple Martin, Rock Wren, Gray Catbird in central, Spotted Towhee in north and west, and Hooded Warbler.

Following along logically perhaps with early arrival dates were a number …

The Unicorn And Christ – Metamorphosis And Symbology, Luis Mendonça De Carvalho, Francisca Maria Fernandes, Maria Fátima Nunes, Ana Maria Costa, Paula Nozes, Ana Paula Figueira

International Journal of Religious Tourism and Pilgrimage

The unicorn is a legendary chimaera that, for centuries, has been present in the mindset of Euro-Mediterranean cultures. Although its morphological description changed, tradition identifies it as an animal like a horse, albeit smaller and with a spiralling horn on its head pointing forward. The unicorn has been known since Antiquity, with references by authors such as Ctesias and Pliny. However, its relevance for medieval Europeans began with the Biblical references to this animal in several Old Testament verses. These verses gave legitimacy to the unicorn, and it was accepted as a tangible animal. During the Middle Ages and early …

Distribution Pattern And Abundance Dynamics Of Asian Openbill (Anastomus Oscitans) In Rice Field Throughout Peninsular Malaysia, Badrulhadza Amzah, Rosli Ramli, Noorhidayah Mamat

Turkish Journal of Zoology

The Asian Openbill (Anastomus oscitans) plays a crucial role in rice field ecosystems by preying on invasive apple snails (Pomacea spp.), potentially reducing the reliance on chemical molluscicides. This study investigated the distribution and abundance dynamics of the stork across major rice granaries in Peninsular Malaysia. Surveys were conducted at 111 sampling points within 30 localities across 11 states during five consecutive rice seasons (2022–2024), with bird counts obtained through binoculars and digital photography. Results indicate that storks are highly concentrated on the northern and central west coasts, where rice fields provide abundant foraging opportunities. In the northern regions (Perlis, …

Turkish Journal of Zoology

Vector control strategies increasingly focus on nonconventional chemicals with high insecticidal efficacy, persistence, and low toxicity to nontarget organisms. The present multiphase study, conducted in laboratory, semifield, and field conditions in Jaipur, Rajasthan, India, evaluated the efficacy of pyriproxyfen (0.5%) (juvenile hormone analog) in controlling mosquito emergence. Laboratory bioassays demonstrated significant susceptibility of Culex tritaeniorhynchus Giles, 1901 (Diptera: Culicidae) larvae, with the first and second instars exhibiting 100% mortality at 1 ppm and third and fourth instars showing emergence inhibition (IE) of 86.11% and 65.28%, respectively. Probit analysis determined lower LC₅₀, LC₉₀, and LC₉₉.₉ values for the first instar larvae …

Turkish Journal of Zoology

This study evaluates the discriminating power of sagittal otolith shape among three species of the genus Clupeonella endemic to the Caspian Sea (Clupeonella grimmi, Clupeonella caspia, and Clupeonella engrauliformis) and one species from the Sea of Marmara (Clupeonella Cultriventris). Identification of these species is challenging due to their morphological similarities, and the taxonomic validity of C. caspia and C. cultriventris remains ambiguous because of their resemblance. Scanning electron microscope (SEM) images were utilized to examine the morphological characteristics of otoliths. Stereomicroscope images were used to calculate six shape indices: rectangularity, roundness, ellipticity, circularity, aspect ratio, and form factor. The outline …

Protein Composition Of The Foam Nest Of Rhacophorus Reinwardtii (Schlegel, 1840) (Anura: Rhacophoridae), With Notes On Breeding Sites Characteristics And Biomedical Applications, Muhammad Asyraf Rijalullah, Nia Kurniawan, Nia Kurnianingsih

Turkish Journal of Zoology

Rhacophorus reinwardtii is endemic to Java Island and is currently experiencing a population decline. Therefore, the sustainability of its offspring is important to prevent species extinction. Foam nest as a biosurfactant structure plays a crucial role as egg protection through major protein components function. However, studies on the functional proteins of rhacophoridae foam nests are limited. Thus, this study aims to uncover the protein-specific components and functions of the R. reinwardtii foam nest. Additionally, the characteristics of breeding sites, including abiotic factors, were also assessed. Total protein concentration of the R. reinwardtii foam nest was determined to be 747.7 μg/mL …

A Singular Case Of Early-Stage Long-Distance Dispersal Of The Smooth Newt, Lissotriton Vulgaris (Linnaeus, 1758) (Amphibia, Caudata), Simone Costa, Francesco Paolo Faraone, Mario Lo Valvo

Turkish Journal of Zoology

To date, the global introduction of alien amphibians and reptiles has likely been facilitated by the expanding plant nursery trade. Here, we report in detail a singular case of unintentional introduction of Lissotriton vulgaris in Sicily. A newt in the final stages of its larval development was found in a private garden pond in north-western Sicily, where aquatic plants from a nursery in Veneto (northeastern Italy) had been introduced two months earlier. The analysis of the mithochondrial markers ND2 and ND4 revealed a shared haplotype between the Sicilian newt and a sample from Treviso, the province of the putative source. …

Impact Of Unconventional Gas Extraction On Tributaries Of Tenmile Creek, Greene County, Pennsylvania: A 12-Year Perspective, Christian L. Beall

Electronic Theses and Dissertations

Much of southwestern Pennsylvania has been central to a rapid increase in development for unconventional natural gas extraction in the past two decades. The continued monitoring of streams over their lifetime as extraction sites is pivotal to understanding the effects of fracking on local waterways and their ability to provide for wildlife and human use. Here, using multiple indices of biotic integrity (IBI), I perform analyses of fish and macroinvertebrate communities as well as water chemistry on two streams, Bates Fork (with shale wells) and Fonner Run (without), as part of a follow-up to work performed there from 2010-2012.

Biomarkers That Could Explain Parasite-Induced Behavioral Alterations In The Golden Shiner (Notemigonus Crysoleucas) – Posthodiplostomum System, Laura D. Nicolas 2025 Nova Southeastern University

Biomarkers That Could Explain Parasite-Induced Behavioral Alterations In The Golden Shiner (Notemigonus Crysoleucas) – Posthodiplostomum System, Laura D. Nicolas

All HCAS Student Capstones, Theses, and Dissertations

Trophically transmitted parasites require an intermediate host to be consumed and often manipulate host phenotype (i.e., morphology, physiology, and/or behavior) to increase predation risk by definitive hosts. Posthodiplostomum is a trematode with a complex life cycle involving snails as first hosts, fish as second intermediate hosts, and piscivorous birds as definitive hosts. In fish hosts, Posthodiplostomum infection has been linked to increased predation, suggesting suppression of antipredator behaviors. However, the specific physiological pathways remained unexplored and changes in the host’s neural, endocrine, and immune systems could be involved. Thus, I examined whether Posthodiplostomum infection intensity was associated with brain serotonin …
