“…Likewise, grasshoppers that could perceive the presence of a predator (spider) selected an intake target higher in carbohydrates than did controls (Hawlena & Schmitz, ). Other studies have shown that omnivorous invertebrates increase the relative intake of plant over animal tissue at higher temperatures (Boersma et al., ; Carreira, Segurado, Laurila, & Rebelo, ; Carreira et al., ; Malzahn, Doerfler, & Boersma, ), presumably to obtain extra carbon to meet the increased metabolic costs for ectotherms at higher temperatures (Boersma et al., ). Studies using chemically defined diets specifically showed that mealworms ( Tenebrio molitor L.) (Rho & Lee, ) and Spodoptera litura caterpillars (Lee, Jang, Ravzanaadii, & Rho, ) increased their preference for carbohydrate relative to protein at higher temperatures.…”

Homeostatic responses of animals to environmentally induced changes in nutrient requirements provide a powerful basis for predictive ecological models, and yet, such responses are virtually unstudied in the wild. We tested for macronutrient‐specific compensatory feeding responses by free‐ranging golden snub‐nosed monkeys (Rhinopithecus roxellana) inhabiting high altitude temperate forests, where they experience a substantial difference in ambient temperature in cold winters vs. warmer springs. The monkeys had free access to natural foods throughout the year, and to ensure that any seasonal differences in nutrient intake were due to homeostatic compensation and not constraints on food availability, we studied the monkeys during periods in which they were provisioned with the same amount of supplementary foods in winter and spring. Thermoregulatory energy costs in winter and spring were calculated using partitional calorimetric estimations of convective and radiative heat loss obtained from thermal imaging of free‐ranging monkeys in situ. Daily nutrient intakes were measured using continuous focal follows (average 6.9 hr/day) of free‐ranging individuals (27 days in spring and 28 days in winter). We used a nutritional geometry framework to integrate these data and test three predictions: (a) In order to remain thermoneutral (balance heat loss with heat expenditure), golden snub‐nosed monkeys increase daily energy consumption during the winter compared to spring; (b) this increase is achieved specifically by increasing intake of the primary energetic nutrients, carbohydrate and lipid, relative to protein; and (c) the seasonal increase in ingested fat and carbohydrate calories will quantitatively match the additional thermoregulatory costs in winter compared with spring. Our results showed that daily metabolisable energy intake in winter (721.5 kJ/mbm) was 1.8 times that in spring (399 kJ/mbm). As predicted, this difference was specific to fat and carbohydrate, whereas seasonal protein intake did not differ significantly. Winter consumption of fat and carbohydrate was 326 kJ/mbm per day greater than in spring, a value that closely matched the seasonal difference in the daily energetic costs of thermoregulation (329 kJ/mbm). This is the first study to test for a match between nutrient‐specific homeostatic compensation and environmentally induced perturbations in nutrient requirements in free‐ranging animals and underpins the potential for the homeostasis framework to provide predictive power to ecological models.

“…The production exceeded 1 million tons with 37 billion USD output in 2017, accounting for 80% of global production according to FAO statistics (FAOSTAT, http://www.fao.org/faost at/en/) and Crayfish Industry Report 2018 (http://www.moa.gov.cn/). This is in contrast to the reality that it considered as an invasive species in Europe and Asia (Carreira et al 2017). The vigorous development of the industry was substantially attributed to the improved optimization of efforts involved in crayfish-rice farming, which original model has been practiced in Louisiana, USA for several decades (Si et al 2017a;Anastacio et al 1999).…”

Increasing evidences suggest that intestinal microbiota balance closely correlated with host's health status could affected by external environment. Integrated crayfish-rice cultivation model is a highly efficient artificial ecosystem widely practiced in subtropical China. Less information is available to estimate the influence response to the micro-ecology of crayfish intestine and so as to influence the biological processes. Thus, 16S rRNA high-throughput sequencing approach was employed to investigate the composition diversity and functions of bacterial community in the intestines of Procambarus clarkii farmed within this model. Results exhibited the highly diversity of microflora with dominant phyla Actinobacteria, Proteobacteria, Tenericutes, Firmicutes and Bacteroidetes. The genera of Candidatus Bacilloplasma and Ornithinibacter were presented as predominant population much exceeds in richness comparing to that of other genus. Despite the highly diversity in the bacterial community, the predicted functions indicated relative consistent in biological processing pathway. Collectively, significant richness of genes was observed involved in amino acid and carbohydrate metabolism and membrane transport processing. This study would contribute to the understanding of the impact of growth conditions on host-microbiota relation especially in aquatic animals.

“…The Red Swamp Crayfish, Procambarus clarkii (Girard, 1852), native to south-central United States (Louisiana) and north-eastern Mexico, has been successfully introduced worldwide for commercial purposes. P. clarkii occupies a key position in invaded ecosystems, with dramatic impacts on ecosystem structure and functions (Gutiérrez-Yurrita et al, 1998; Alcorlo et al, 2004). This species is an omnivore with plants as the first food source (88.45% of occurrence in the stomachs of the crayfish studied) followed by animals (59.16%) and detritus (31.19%) (Gutiérrez-Yurrita et al, 1998).…”

Response of Macrophyte Traits to Herbivory and Neighboring Species: Integration of the Functional Trait Framework in the Context of Ecological Invasions

et al. 2019

With the increase in the number of introduced species each year, biological invasions are considered as one of the most important environmental problems for native biodiversity. In invaded habitats, the establishment of exotic plant species depends on the abiotic and biotic environment. Herbivores and neighboring plants (native or exotic) comprise an important part of the latter. Herbivores cause trophic and non-trophic damage to focal plants, which respond to herbivory by varying their different traits quantitatively (e.g., growth rate and biomass changes) and qualitatively (e.g., variation in morphological and chemical defenses strategies affecting plant palatability). Neighboring plant species also affect functional traits and the fitness of focal plant species, thus herbivore effects on a focal plant could also depend indirectly on the palatability and defensive traits of the neighboring species inside the community. Here, in a first step toward the integration of associational susceptibility/resistance theories in the field of ecological invasion, we performed a microcosm experiment to consider the effects of an exotic crayfish on the growth rate, morphological traits and damage level of three macrophytes (two exotic, one native) growing in pairwise combinations. We found that (i) the response to herbivore presence and to neighboring species identity seemed to be species specific, and (ii) crayfish enhance the fragmentation rate of the two exotic macrophytes Ludwigia grandiflora and Egeria densa in the presence of the native macrophyte Myriophyllum spicatum, which could indirectly facilitate their invasion success. Indeed, fragmentation can increase dispersal abilities of the exotic macrophytes considered in this study as they are able to generate new plants from their fragments. However, our results showed that the interaction herbivore-neighbor species was hardly significant. Our paper presents some first results on associational resistance/susceptibility and lays the foundation for developing a general framework that combines plant community ecology and biological invasion ecology to explain invasive species success.
