“…This increased allometry during the juvenile phase can enhance the courtship behavior and the reproductive performance of these small males at the onset of sexual maturity. However, the enlarged appendage of male fiddler crabs has an important physiological cost, since it demands high energy expenditure for its growth, maintenance and display during reproductive activities (Matsumasa & Murai 2005, Allen & Levinton 2007, Colpo & López-Greco 2018.…”

“…The different cheliped growth rates of the adult males between the three populations studied could be a response to the local features of each mangrove, which probably represent distinct values of resources and energetic demands.

Considering that the three populations of M. vocator here studied inhabit the same latitude range and experience similar conditions of temperature, we suggest that the different maturity sizes recorded could be a consequence of the contrasting local conditions among mangroves, which can imply differences in the availability of resources or in the requirement of physiological costs.…”

The growth rates and size at maturity of decapod crustaceans usually vary throughout latitudes. Here, we evaluated whether these life history traits can be stable within the same latitude range, where some environmental factors are constant, especially temperature. To this end, we estimated and compared the growth rates and size at sexual maturity of three populations of the fiddler crab Minuca vocator, located at latitude 23° S, in mangroves of the subtropical Brazilian coast. Variations in the growth rate of the abdominal width of females and of the propodus of the major cheliped of males were assessed by the allometric technique. The abdomen growth rates of females and the cheliped growth rates of males varied among the three populations, resulting in different sizes at maturity. These results do not support our prediction that growth rates and size at sexual maturity would remain stable in populations of the same latitude range. The differences in these life history traits could be a consequence of contrasting local conditions among mangroves. Therefore, we suggest that these crabs show plasticity and responsiveness to local-scale environmental variations, to optimize the energy allocation for maintenance, reproduction, and somatic growth.

“…In this study, lysozyme (LYZ) (Zhang et al, 2021), alkaline phosphatase (AKP) (Chen et al, 2020), glutamic pyruvic transaminase (GPT) and glutamic oxaloid transaminase (GOT), which can reflect the liver health of crustaceans (Cheng et al, 2020), and superoxide dismutase (SOD) were chosen to evaluate the nonspecific immunity of P. clarkia (Liu et al, 2020). In addition, the metabolic rates of crustaceans can be different from gender (Colpo and Lopez-Greco, 2018), so this experiment will also consider comparing the different effects of dietary GBL on male and female P. clarkia.…”

This trial investigated the effect of dietary Ginkgo biloba leaf (GBL) on the growth performance and nonspecific immunity of red swamp crayfish Procambarus clarkii. 180 Crayfishes were randomly divided into three groups. One group was fed with basic diet, whereas the other two groups were fed with diets containing 1% and 3% GBL. After 32 days of feeding, GBL addition tended to increase the body weight gain rate compared with control. In 3% GBL group, the bodyweight gain rate of male crayfish was higher than that of female crayfish. While female crayfish were advantageous in terms of meat yield. Liver-related indexes were influenced by GBL addition and 3% GBL could reduce glutamic pyruvic transaminase and glutamic oxaloacetic transaminase as well as total cholesterol in male crayfish, showing its function in liver protection. Moreover, GBL addition effects on liver protection was better in male crayfish than female crayfish.

“…This difference in cheliped characteristics cause sex-related constraints on their time-energy budget (Valiela et al, 1974;Darnell et al, 2013), which, ultimately, reflect on the individual thermal physiology (Pörtner, 2012). During the reproductive season female fiddler crabs invest more energy than males to develop their gonads (Yamaguchi, 2003;Hartnoll, 2006;Colpo and Loṕez-greco, 2018). The higher energetic investment in reproduction by females is known to constrain their energy budgets, limit growth, increase mortality rates, reduce feeding and hinder other functions (Hartnoll, 2006;Guderley and Pörtner, 2010).…”

Global temperature increases are predicted to have pronounced negative effects on the metabolic performance of both terrestrial and aquatic organisms. These metabolic effects may be even more pronounced in intertidal organisms that are subject to multiple, abruptly changing abiotic stressors in the land-sea transition zone. Of the available studies targeting the intertidal environment, emphasis has largely been on water-breathing model organisms and this selective focus resulted in limited reliable forecasts on the impact of global warming on primarily air-breathing intertidal species. We investigated the thermal sensitivity of six phylogenetically related fiddler crab species that occupy different microhabitats on intertidal shores from south America and east Asia to test how bimodal-breathing intertidal ectotherms cope with thermal stress. We examined the metabolic physiology and thermal limits of the crabs by measuring their cardiac function and oxygen consumption along a thermal gradient. Their specific thermal microhabitat was also appraised. We found that subtropical fiddler crab species inhabiting vegetated microhabitats have lower upper lethal temperatures and therefore greater thermal sensitivity in comparison to their tropical counterparts. Additionally, females exhibited higher oxygen consumption and lower lethal temperatures in comparison to males. Our results contradict previous predictions that species from higher latitudes that experience greater temperature variability have broader latitudinal distributions, greater phenotypic plasticity and lower thermal sensitivity. Furthermore, the higher thermal sensitivity demonstrated by female fiddler crabs with respect to males strongly suggests a role of both gametogenesis and physiological dimorphism on the thermal performance of tropical and subtropical intertidal organisms. These observations ultimately, advocates for further studies on sex-biased and development-biased thermal sensitivity before drawing any generalizations based on a single sex or life stage.
