The conservation of freshwater turtle species depends on precise and effective monitoring techniques. Environmental DNA (eDNA) analysis is a potential method for identifying cryptic and elusive turtle species in aquatic ecosystems. eDNA analysis can help to identify key regions for conservation efforts and monitor changes in population levels over time. This study aims to evaluate the effectiveness of a rapid eDNA detection method for the yellow mud turtle (Kinosternon flavescens, an indicator species that is endangered in some states in the USA), which inhabits local oxbow lakes (e.g., resacas) in Cameron County, South Texas. A species-specific nested PCR …

Abdominal aortic aneurysms (AAA) are a life-threatening cardiovascular disease for which there is a lack of effective therapy preventing aortic rupture. During AAA formation, pathological vascular remodeling is driven by vascular smooth muscle cell (VSMC) dysfunction and apoptosis, for which the mechanisms regulating loss of VSMCs within the aortic wall remain poorly defined. Using single-cell RNA-Seq of human AAA tissues, we identified increased activation of the endoplasmic reticulum stress response pathway, PERK/eIF2α/ATF4, in aortic VSMCs resulting in upregulation of an apoptotic cellular response. Mechanistically, we reported that aberrant TNF-α activity within the aortic wall induces VSMC ATF4 activation through the …

Middle Bronze Age Tombs At Fassuta (Pp. 17–42), Lilly Gershuni, Mordechai Aviam

'Atiqot

Located in the northern upper Galilee, the ancient site was established on a hill named Fasil Danyal, in the vicinity of which are several springs. A salvage excavation was undertaken in two built tombs, damaged during construction in the village of Fassuta. Tomb 1 is rock-cut, rectangular-shaped and covered with limestone slabs. It contained pottery vessels, metal artifacts — among them weapons and a bronze belt and buckle — and a steatite scarab of Neferhotep I (an heirloom). Tomb 2 is much smaller, consisting of only a modest content, including a votive bowl. The tombs were probably part of a …

Two Horn-Shaped Glass Vessels From The Ancient Cemetery At Migdal Ha-‘Emeq (Pp. 123–126), Yael Gorin-Rosen Jan 2025

Two Horn-Shaped Glass Vessels From The Ancient Cemetery At Migdal Ha-‘Emeq (Pp. 123–126), Yael Gorin-Rosen

'Atiqot

Two horn-shaped vessels, recovered from the Migdal Ha-‘Emeq caves, represent a rare type that was here-to-far known only from collections around the world. Both horns are mold-blown, decorated with ribbing, dating from the fourth to the early fifth centuries CE. As these horns were found in situ, they were dated both on the basis of their typology and archaeological context. It is suggested that the horn-shaped vessels were locally produced in a glass workshop situated in the Lower Galilee.

Tel ‘Afar: A Byzantine Site South Of Caesarea (Pp. 95–118), Martin Peilstöcker

'Atiqot

Salvage excavations at Tel ‘Afar, about six kilometers south of Caesarea, unearthed remains dating to the Byzantine period. A massive building was exposed, with square towers at its corners, buttresses on each side and two vaulted openings. The finds from the building and around it clearly date to the Byzantine period, but provide no clue to its use or function. Numerous roof tiles, marble fragments and many tessarae were found in all the excavated areas – they might belong to the building revealed during Porath’s excavations at the site, which he identified as a villa belonging to a wealthy citizen …

'Atiqot

Excavations undertaken in two separate areas (100, 200) at Sha‘ar Ha-Golan, revealed the remains of domestic structures dating to Early Bronze Age IV. These represent the remains of a single-stratum rural settlement that extended over some 200 dunams, one of the largest settlements of this period that have been exposed so far in the country. The structures are multi-roomed rectilinear buildings, with dwelling units comprising three or more rooms. The plans of the buildings are not unified; most of them have a large central broadroom, its roof sometimes supported by columns, which stood on stone bases. Additional elements, such as …

'Atiqot

The finds from the favissa at ‘En Hazeva represent a cultic assemblage that had been used in a temple that existed at the site at the end of the Iron Age and was intentionally buried. The objects retrieved from the favissa included anthropomorphic statues, cylindrical stands, bowls, goblets, tripod cups, pomegranate-shaped pendants, stone altars and a stone human statue. The cultic vessels are well-grounded in the religious iconography of the Ancient Near East in general and the Levant in particular. These finds resemble those from Ḥorbat Qitmit, where they were defined as Edomite. However, no indication of the deity worshipped …

The Cultic Assemblage From ‘En Hazeva: The Restoration Process (Pp. 177–183), Michal Ben-Gal Jan 2025

The Cultic Assemblage From ‘En Hazeva: The Restoration Process (Pp. 177–183), Michal Ben-Gal

'Atiqot

This article describes the restoration process of the cultic vessels recovered from the Favissa at ‘En Hazeva. The objects were broken into very small pieces, which made their mending a challenging task. At the end of the restoration process, 70 clay vessels and objects were restored; most had a complete profile. It was evident that several vessel groups were made of the same batch of clay and fired under similar conditions, perhaps even made by the same potter. This may suggest that there was a functional affinity between the vessels and that they were most likely used together.

The Bone And Horn Industry In Late Ottoman Nazareth: The Evidence From Shihab Ad-Din (Pp. 61*–80*), Noa Raban-Gerstel, Guy Bar-Oz, Yotam Tepper

'Atiqot

Animal bones recovered from excavations at Shihab ad-Din, Nazareth, provide an important source of knowledge about diet and subsistence practices in the past. The faunal remains presented in this report were retrieved from Crusader/Mamluk and Ottoman strata, and indicate bone-tool manufacturing at the site. The present study demonstrates that comprehensive analysis of such faunal assemblages can provide primary data on the diversity of the animals exploited, as well as on butchering and consumption patterns. Such studies can provide important information that eventually will enable us to evaluate issues of broader social importance.

Human Skeletal Remains From The Burial Caves At Sha‘Ar Efrayim (Pp. 75–78), Yossi Nagar Jan 2025

Human Skeletal Remains From The Burial Caves At Sha‘Ar Efrayim (Pp. 75–78), Yossi Nagar

'Atiqot

The anthropological study of the human skeletal remains from the five burial caves at Sha‘ar Efrayim pointed to a difference between the burial traditions of the Chalcolithic population and those of the Early Bronze Age I population. The most prominent difference is the absence of infants in the Chalcolithic burials, in contrast to their presence in the EB I sample. This might indicate there was no population continuity between these two succeeding periods.

'Atiqot

The faunal remains from the Sha‘ar Efrrayim burial caves (Nos. 1, 3–5) were attributed to two main periods, in accordance with the other finding in the caves: Late Chalcolithic and Late Chalcolithic–Early Bronze Age I. They comprise a small, but important, sample, representing a wide range of both domestic and wild taxa. These remains seem to be the first convincing evidence of animal offerings in Late Chalcolithic/EB IA contexts in the southern Levant.

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Psychosocial stressors are known to promote cocaine craving and relapse in humans but are infrequently employed in preclinical relapse models. Consequently, the underlying neural circuitry by which these stressors drive cocaine seeking has not been thoroughly explored. Using Fos expression analyses, we sought to examine whether the ventromedial hypothalamus (VMH) or periaqueductal gray (PAG), two critical components of the brain's hypothalamic defense system, are activated during psychosocial stress-induced cocaine seeking. Adult male and female rats self-administered cocaine (0.5 mg/kg/inf IV, fixed-ratio 1 schedule, 2 h/session) over 20 sessions. On sessions 11, 14, 17, and 20, a tactile cue was present …

Climate Influence On Both Spatial And Temporal Patterns Of Rocky Intertidal Community Structure In San Diego, California, Emily Jenkins Jan 2025

Climate Influence On Both Spatial And Temporal Patterns Of Rocky Intertidal Community Structure In San Diego, California, Emily Jenkins

Theses

The rocky intertidal ecosystem, the coastal area between high and low tides, serves as a critical buffer between land and sea. This ecosystem supports a diverse array of species and provides rich opportunities for exploration and education. With the influence of climate change, this ecosystem faces significant shifts in species distribution, resilience and recovery from environmental disturbances, as well as habitat loss (Jackson & McIlvenny 2011; Jueterbock et al. 2013; Menge & Gravem 2022; Rilov et al. 2021; Sagarin & Barry 1999). Between 2014-2016, climate anomalies El Niño (ENSO) and the Pacific Decadal Oscillation (PDO) combined to create a period …

Evaluation Of Panicum Maximum Cultivars Under Grazing, V.P B. Euclides, M.C M. Macedo, A Vieira, M P. Oliveira

IGC Proceedings (1977-2023)

A grazing trial was conducted in Brazil, for a 3-year period, to study animal production from Panicum maximum cultivars (Coloniao, Tobiatii and Tanz5nia-1). Three 1.5-hn paddocks of each cultivar were stocked continuously with 3 steers, and additional grazers were added or removed as required to ensure similar grazing pressure in each treatment. Steers on Tanzania-I had a superior average daily gain (ADG) to those on Tobiatii and Coloniffo. However, the lack of difference in carrying capacity between Tanzdnin and Tobiatil pastures resulted in similar live-weight gain (LWG)/ha. The ADG and LWG/ ha of Coloniilo were significantly lower than the other …

Evaluation Of Brachiaria Decumbens And Brachiaria Brizantha Under Grazing, V.P B. Euclides, A H. Zimmer, M P. Oliveria

IGC Proceedings (1977-2023)

A 3-year grazing trial was conducted in Brazil, to relate changes in sward characteristics of B. decumbens and B. brizantha to animal live-weight gain (LWG). Three 1.5-ha paddocks of each grass species were stocked continuously with 3 steers, and additional grazers were added or removed as required to ensure similar grazing pressure in each treatment. Despite similar (P>0.85) annual average daily gains (ADO) of steers grazing both species, the ADO of steers grazing B. brizantha pasture was significantly (P<0.05) higher during the wet season, and significantly (P<0.05) lower in the dry period, when compared with those on B. decumbens. Annual LWG per area of both species were also similar (P>0.85). The best predictor of ADO was …

Large-Scale Property Demonstrations Of The Effect Of Sexa Stylo And Phosphorus On Beef Cattle Growth In Central Queensland, Australia, C H. Middleton, K J. Murphy, G W. Blight, Vicki-Lee Hansen

IGC Proceedings (1977-2023)

Seca style (Stylosanthes scabra) was oversown into black speargrass (Heteropogon comortus)•dominant pasture after a burn at 2 sites in central Queensland, and the pasture was continuously grazed. At one site with <5 ppm bicarbonate-extractable soil P, Seca growth was poor and gave only a small animal growth response (18 kg/steer/year) over native pasture. With the addition of superphosphate (27 kg P/ha) the Seca-native grass produced an additional live-weight gain of 70 kg/ steer/year over the native pasture control. At a second site with 6-8 ppm available soil P, Seca grew well, and with a P supplement given to steers, live-weight gains were 40 kg/steer/year more than for P­supplemented animals grazing native pasture. Oversowing Seca into native pasture with P as fertiliser or a supplement can dramatically improve animal performance. The project was conducted on private properties and was aimed to focus producer attention on this technology, which is suited to large areas of northern Australia.

Increasing Cool-Season Production From Irrigated Leucaena Leucocephala, D Pratchett, S Petty

IGC Proceedings (1977-2023)

Annual live-weight gains of cattle grazing irrigated Leucaena leucocephala in the ORIA (Ord River Irrigation Area) average 0.7 5 kg/day al a stocking rate of 7.5 animals/ha. During the dry season the cooler temperatures reduce the growth rate of leucaena and live­weight gains are reduced lo about 0.5 kg/day. To date growth rates have been maintained by reducing stocking rates but a continuous supply of stock is now required to meet the demands of a local abattoir in the ORIA. During the cooler period a supplement of 1.5 kg maize/animal/day plus hay increased the live-weight gain of cattle to 0.75 …
