In this study, we assess the effect of interannual climatic variation on resource allocation to vital rates in a cactus with biogeographical rarity (Thelocactus leucacanthus ssp. schmollii). Eight-year observations were used to relate vital rates to climatic data using population projection matrix models and Spearman correlations. The finite rate of population growth (λ) indicates, on average, a population in equilibrium. The transition from seeds to seedlings and the growth of seedlings, juveniles, and adults are the stages of the lifecycle with the highest selection pressure, with adults and juveniles being the categories with the greatest contribution to λ. This species allocates more resources to survival than to growth or reproduction during its lifecycle. The trade-off between the survival of adult individuals and fertility seems more marked in years with higher rainfall and minimum temperature turned out to be a key factor for population maintenance.

The mean body mass condition index varied significantly over time, with significantly higher values in males in summer and autumn 2011. All the plasma variables (osmolality and sodium, potassium, chloride, and urea concentrations) varied significantly among seasons, increasing during the summer dry period and decreasing after rainstorms. Osmolality and solute concentrations in voided urine were more variable than in plasma, with more pronounced decreases related to rainfall events. Soluble potassium was the major cation in voided urine. Potassium concentration decreased markedly following rainfall events, and rapidly increased in late summer and autumn 2011, when some green plants were available. As spring progressed and tortoises gained body mass while feeding on hydrated vegetation, urine osmolalities decreased, and then re-increased during the dry summer period, becoming essentially iso-osmotic with plasma. When summer thundershowers dropped rain, tortoises drank water, voided concentrated bladder urine, and stored dilute urine; body mass, plasma and urine concentrations returned to hydrated levels. Tortoises exhibited a tolerance to osmotic stressors that allowed them to osmoregulate opportunistically in their arid environments via allostasis, a process that allows maintaining homeostasis through change. When bladder urine becomes iso-osmotic to plasma, tortoises tolerate increases in osmolality and concentrations of plasma solutes. The success of facultative osmoregulation and variable ‘allostasis’ would depend on the occurrence of summer rain events as a source of drinking in osmotically stressed tortoises.</div>","PeriodicalId":51080,"journal":{"name":"Journal of Arid Environments","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139726672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings reveal that fog is a regular phenomenon in the area, occurring from 3% to 20% of the year.

A wide range of types and dimensions is found throughout the region, but only the small V-shaped type is found in the cultural landscape of the Timnian, a Mid-Holocene culture in the southern Levantine deserts. The Timnian economy was based on nomadic pastoralism, rearing small herds of goats/sheep. In the southern Levantine deserts, pastoralism had to be augmented by other carbohydrate sources. It is apparent that the Timnians invested much effort and resources in kite construction to hunt ungulates; however, faunal assemblages from habitation camps, burial fields and ceremonial complexes show very few bones of hunted game.
