Is membrane androgen and estrogen receptor signaling imperative in the governing function of the adrenal cortex in the Eurasian beaver (Castor fiber L.)? J. Exp. Zool. Part A (IF 2.8) Pub Date : 2024-03-18 G. Lonc, A. Hrabia, I. Krakowska, A. J. Korzekwa, M. Zarzycka, D. Wolak, M. Wajdzik, M. Kotula-Balak
There is a need to fully know the physiology of Eurasian beaver due to its essential role in environmental homeostasis. However, a “human factor“ impacts this, including stress conditions and environmental pollution. Adrenal glands protect these all. The regulation of endocrine processes by nonclassical androgen and estrogen signaling, the first and fastest control, is still a matter of research. The

Budding and regeneration potential of a calyx of a freshwater Kamptozoan, Urnatella gracilis J. Exp. Zool. Part A (IF 2.8) Pub Date : 2024-03-14 Teruhisa Ishii, Keiko Ooga, Manami Kato, Ayako Sakai
There are only two freshwater Kamptozoans worldwide: Urnatella gracilis Leidy, 1851 and Loxosomatoides sirindhornae Wood, 2005. U. gracilis is present in Japan and is expanding its distribution, especially in Lake Hachiro. We investigated the budding and regeneration potential of a calyx of U. gracilis to clarify the mechanisms underlying its ability of regeneration. Our experiments revealed that the

Karam‐Martínez, José Alberto Montoya‐Márquez, Tania Zúñiga‐Marroquín, Felipe Becerril‐Morales, Valentina Islas‐Villanueva
Future climate change scenarios project that the increase in surface temperatures will affect ocean temperatures, inducing shifts in marine biodiversity. Sea turtles are species that are particularly vulnerable to the effects of climate change because temperature is a factor that influences embryonic development. We collected clutches of olive ridley turtles from a mass‐nesting beach in the Mexican

Biopsy has recently become a preferred protocol for sampling the skin and blubber of many cetacean species, although it is desirable to collect as minimally invasive as possible. Here, the effect of biopsy sampling on the captive common bottlenose dolphins was evaluated by analyzing the process of wound healing and changes in hematological and blood biochemical parameters after biopsy using a puncher

Differential leg and trunk operation during skipping without and with hurdles in bipedal Japanese macaque J. Exp. Zool. Part A (IF 2.8) Pub Date : 2024-03-04 Reinhard Blickhan, Emanuel Andrada, Eishi Hirasaki, Naomichi Ogihara
When locomoting bipedally at higher speeds, macaques preferred unilateral skipping (galloping). The same skipping pattern was maintained while hurdling across two low obstacles at the distance of a stride within our experimental track. The present study investigated leg and trunk joint rotations and leg joint moments, with the aim of clarifying the differential leg and trunk operation during skipping

The increased size and enhanced compliance of the aortic bulb—the enlargement of the ascending aorta—are believed to maintain blood flow in pinnipeds during extended periods of diastole induced by diving bradycardia. The aortic bulb has been described ex vivo in several species of pinnipeds, but in vivo measurements are needed to investigate the relationship between structure and function. We obtained

Immunolocalization of apelin receptor (APJ) in mouse seminiferous epithelium J. Exp. Zool. Part A (IF 2.8) Pub Date : 2024-02-23 Milirani Das, Guruswami Gurusubramanian, Vikas K. Roy
The apelin receptor (APJ) belongs to the member of the G protein‐coupled receptor family, and expression of APJ has been reported in the different cell types of testis. The seminiferous tubules in the testis can be identified as different stages (I–XII). It has been also suggested that different factors could be expressed in stage and cell‐specific manner in the seminiferous tubules. Recently, we also

Understanding the potential limits placed on organisms by their ecophysiology is crucial for predicting their responses to varying environmental conditions. A main hypothesis for explaining avian thermoregulatory mechanisms is the aerobic capacity model, which posits a positive correlation between basal (basal metabolic rate [BMR]) and summit (Msum) metabolism. Most evidence for this hypothesis, however

Testosterone is closely related to Leydig cell activity, environmental factors, and androgen receptor distribution in adult male lizards of Liolaemus cuyanus (Reptilia: Liolaemidae) during the reproductive cycle J. Exp. Zool. Part A (IF 2.8) Pub Date : 2024-02-19 Andrea Anabella Barauna, María Inés Conte, Jorge Leandro Leporati, Lorena Beatriz Quiroga, Eduardo Alfredo Sanabria, Miguel Walter Fornés
Testosterone, the primary sex hormone in male lizards, is closely linked to Leydig cell activity (the cells where steroidogenesis occurs) throughout the reproductive cycle, but testosterone action is related to androgen receptors (ARs) distribution in the seminiferous epithelium. In temperate zones, environmental factors detected through the hypothalamic–pituitary–gonadal axis, downregulate plasma

Changes in environmental temperature may induce variations in thermal tolerance and sensitivity in ectotherm organisms. These variations generate plastic responses that can be analyzed by examining their Thermal Performance Curves (TPCs). Additionally, some performance traits, like locomotion, could be affected by other factors such as biological interactions (e.g., predator–prey interaction). Here

Dormancy represents an investment with its own costs and benefit. Besides the advantage obtained from the avoidance of harsh environments and from the synchronization of life cycles with seasonal changes, an organism could benefit from a temporary stop in growth and reproduction. To test this hypothesis a transgenerational experiment was carried out comparing the life history traits of clonal females

Neural control of reproduction in reptiles J. Exp. Zool. Part A (IF 2.8) Pub Date : 2024-01-21 Nicholas T. Shankey, Rachel E. Cohen
Reptiles display considerable diversity in reproductive behavior, making them great models to study the neuroendocrine control of reproductive behavior. Many reptile species are seasonally breeding, such that they become reproductively active during their breeding season and regress to a nonreproductive state during their nonbreeding season, with this transition often prompted by environmental cues

Winter is an energetically challenging period for many animals in temperate regions because of the relatively harsh environmental conditions and reduction in food availability during this season. Moreover, stressors experienced by individuals in the fall can affect their subsequent foraging strategy and energy stores after exposure has ended, referred to as carryover effects. We used exogenous cortisol

A hallmark of the vertebrate stress response is a rapid increase in glucocorticoids and catecholamines; however, this does not mean that these mediators are the best, or should be the only, metric measured when studying stress. Instead, it is becoming increasingly clear that assaying a suite of downstream metrics is necessary in stress physiology. One component of this suite could be assessing double-stranded

Immune responses can increase survival, but they can also incur a variety of costs that may lead to phenotypic trade-offs. The nature of trade-offs between immune activity and other components of the phenotype can vary and depend on the type and magnitude of immune challenge, as well as the energetic costs of simultaneously expressing other traits. There may also be sex-specific differences in both

In studies of mammalian mastication, a possible relationship has been proposed between bilateral recruitment of jaw adductor muscle force during unilateral chewing and the degree of fusion of the mandibular symphysis. Specifically, species that have unfused, mobile mandibular symphyses tend to utilize lower levels of jaw adductor force on the balancing (nonchewing) than the working (chewing) side of

A simple method for effective cryopreservation of antlerogenic periosteum of sika deer J. Exp. Zool. Part A (IF 2.8) Pub Date : 2023-08-28 Jiping Li, Dongxu Wang, Jing Ren, Yusu Wang, Pengfei Hu, Chunyi Li
Antlerogenic periosteum (AP) is the unique tissue type that gives rise to antlers and their antecedents, the pedicles. Deer antlers are the only mammalian organ that can fully regenerate. Efficient investigation of the mechanism of antler formation and regeneration requires year-round availability of AP, but naturally AP can only be obtained less than two months in a year. In the present study we took
