We obtai ned geo-refere need occurre nee and climatic data from in dividual localities for 59 species of terrestrial elapid snakes, used phylogenetic generalized least squares regression to investigate spatial and cladistic patter ns of variation in climatic niche breadths, and compared patter ns within and across regions and clades to see if they parallel or differ from each other. Specifically, we test (1) whether a species' climatic niche breadth on a given niche axis relates to its position along that axis, and to its climatic niche breadth on another niche axis, and (2) whether variation in niche breadths among species is explained by within-locality variation in climatic conditions or by among-locality variation. We found that:(1) there is an overall global patter n, and patter ns in individual regi ons or clades gen erally parallel each other and global patter ns;(2) species in wanner environments have narrower temperature niche breadths (TNBs);(3) precipitation niche breadth (PNB) and position are positively related;⑷ TNB and PNB are not related;and ⑸ within-locality variation in climatic conditions explains most variation in TNBs, whereas among-locality variation explains most variation in PNBs. Our results are consistent with those reported for lizards of the families Phrynosomatidae and Varanidae, con firm the importance of withi n-locality n iche breadth to species n iche breadth, and show a more im porta nt role of amon g-locality n iche breadth in affecting species niche breadth in terrestrial elapids than in lizards.

Monitor lizards(Varanidae)inhabit both the mainland and islands of all geological types and have diversified into an exceptionally wide range of body sizes,thus providing an ideal model for examining the role of mainland versus island in driving species *** we use phylogenetic comparative methods to examine whether a link exists between body size driven diversification and body size-frequency distributions in varanid lizards and to test the hypothesis that island lizards differ from mainland species in evolutionary processes,body size,and life-history traits(offspring number and size).We predict that:1)since body size drives rapid diversification in groups,a link exists between body size-driven diversification and body size-frequency distributions;2)because of various environments on island,island species will have higher speciation,extinction,and dispersal rates,compared with mainland species;3)as a response to stronger intraspecific competition,island species will maximize individual ability associated with body size to outcompete closely-related species,and island species will produce smaller clutches of larger eggs to increase offspring *** results confirm that the joint effect of differential macroevolutionary rates shapes the species richness pattern of varanid *** is a link between body size-driven diversification and body sizefrequency distributions,and the speciation rate is maximized at medium body *** species will have higher speciation,equal extinction,and higher dispersal rates compared with mainland *** clutch size and larger hatchling in the island than in mainland species indicate that offspring quality is more valuable than offspring quantity for island varanids.

Reproductive traits of the gray ratsnake Ptyas korros from three geographically distinct populations

Current Zoology 2012年第6期58卷 820-827页

Abstract We collected gravid gray rat snakes Ptyas korros from three geographically distinct populations in China, Chenzhou （CZ）, Jiangshan （JS） and Dinghai （DH）, to study geographical variation in female reproductive traits. Egg-laying dates differed among the three populations such that at the most northern latitude egg-laying was latest, and earliest at the most southern latitutde. Clutch size, clutch mass, egg mass, egg shape, within clutch variability in egg sizes and relative clutch mass differed among the three populations, whereas post-oviposition body mass did not. Except for egg-laying date, none of the traits examined varied in a geographically continuous trend. CZ and DH females, although separated by a distance of approximately 1100 km as the crow flies, were similar in nearly all traits examined. JS females were distinguished from CZ and DH females by their higher fecundity （clutch size）, greater reproductive output （clutch mass） and more rounded eggs. Our data do not validate the prediction that larger offspring should be produced in colder localities. The absence of an egg size-number trade-off in each of the three populations presumably suggests that P. korros is among species where eggs are well optimized for size within a population.

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

以不同认知负荷的连环数认知运算为实验材料,以小学三到六年级175名学生为被试,考察了认知负荷对小学生工作记忆资源分配策略的影响。结果表明:认知负荷的难度明显地影响到了小学生工作记忆资源分配策略。在策略的选择方面,认知负荷对于小学生认知操作成绩的影响力在低年龄段时没有达到显著性差异,而小学六年级则差异显著;在策略的正确率方面,认知负荷难度的影响力随年级的升高而相对减少;在策略的解题速度方面,认知负荷的难度也明显地影响到了小学生工作记忆资源分配策略的解题速度。
