| a taxonomic revision of small neotropical saurian malarias allied to plasmodium minasense. | saurian malaria species which produce schizonts smaller than normal erythrocyte nuclei, with 4-8 merozoietes and gametocytes equal to or smaller than erythrocyte nuclei in size, parasitizing hosts of the lizard families scincidae, iguanidae and teiidae in the neotropics are considered to be plasmodium minasense carini and rudolph, 1912. subspecific designations are given to distinctive populations parasitizing different host species: p. minasense minasense is recognized from the type host, mabuy ... | 1979 | 533109 |
| a taxonomic reconsideration of some plasmodium species from iguanid lizards. | saurian plasmodium populations previously identified as p. tropiduri from panama are described as subspecies or distinct species. the nominate subspecies, p. tropiduri tropiduri parasitizes tropidurus species from brazil, guyana and venezuela. two other subspecies occur in panama, p. tropiduri panamense from anolis biporcatus and p. tropiduri aquaticum from the semi-aquatic lizards anolis lionotus and a. poecilopus. parasites found in anolis frenatus are described as a distinct species, p. margi ... | 1979 | 539715 |
| additional plasmodium species from anolis lizards of hispaniola and panama. | saurian malaria parasites in the caribbean were previously represented by only two species, plasmodium azurophilum and p. floridense. an additional three species of plasmodium occur on hispaniola which appear, because of morphometric and qualitative similarities, to be related to south and middle american species: a subspecies of plasmodium tropiduri in anolis cybotes; a population of plasmodium minasense anolisi in a. cybotes and a. distichus; and another parasite in a. distichus which is desig ... | 1989 | 2759768 |
| acanthocephalus saurius n. sp. (acanthocephala: echinorhynchidae) and other helminths from the lizard norops limifrons (sauria: polychrotidae) from costa rica. | acanthocephalus saurius n. sp. from the small intestine of norops limifrons collected in costa rica is described and illustrated. acanthocephalus saurius n. sp. represents the third acanthocephalan species in which gravid individuals have been found in lizard hosts. in addition to a. saurius; 1 species of trematoda, mesocoelium monas; 3 species of nematoda, piratuba digiticauda, strongyluris panamaensis, and acuariidae gen. sp. (larvae in cysts) were found. | 2003 | 12880258 |
| patterns of second-to-fourth digit length ratios (2d:4d) in two species of frogs and two species of lizards at la selva, costa rica. | it is now well documented that androgen and estrogen signaling during early development cause a sexual dimorphism in second-to-fourth digit length ratio (2d:4d). it is also well documented that males of mammalian species have a smaller 2d:4d than females. although there are discrepancies among 2d:4d studies in birds, the consensus is that birds exhibit the opposite pattern with males having a larger 2d:4d than females. the literature currently lacks substantial information regarding the phylogen ... | 2012 | 22262453 |
| host association and the capacity of sand flies as vectors of lizard malaria in panama. | in this paper the capacity of sand flies (lutzomyia) as vectors of parasites that cause malaria in anoles (anolis limifrons) in the zona de canal, panama was investigated. inhabiting all study plots, often in local abundance, l. trinidadensis emerged as the principal candidate sand fly vector; the results of surveys did not suggest a likely mosquito vector. although l. trinidadensis and infected anoles co-inhabited all plots, their abundances seemed unrelated. no evidence that sand flies parasit ... | 1992 | 1356940 |
| thermal quality influences habitat use of two anole species. | regeneration of secondary forests on previously deforested or degraded land is one of the most dominant forms of land-use change in the tropics. however, the response of animal communities to forest regeneration is poorly understood. to evaluate support for thermal quality as a mechanism driving reptile species distributions during secondary forest succession, we measured operative temperatures and occupancy in three successional forest stages (pasture, secondary forest, and old growth forest) f ... | 2018 | 30017052 |
| condition dependence of shared traits differs between sympatric anolis lizards. | in many species, sexually selected combat and display traits can confer dramatic fitness benefits to males by aiding in mate acquisition, so individuals maximally invest energy into their growth and maintenance. such traits are deemed condition-dependent, as the energy that is available for investment depends on the health and condition of the individual. condition dependence is present in a wide range of traits across many taxa, but the extent to which condition dependence varies among shared t ... | 2017 | 29356407 |
| predation on lizard eggs by ants: species interactions in a variable physical environment. | one explanation for long-term fluctuations in population density is that the intensity of interactions between species is variable. a population can experience variation in the intensity of a species interaction if (1) the density of species with which it directly interacts changes and/or (2) the strength of the interaction (i.e., per capita effects) changes. at barro colorado island, panama, the tropical lizard anolis limifrons exhibits wide annual fluctuations in density. previous studies have ... | 1999 | 28307980 |
| demographic correlates of variable egg survival for a tropical lizard. | anolis limifrons is a small iguanid lizard that is found in lowland rainforest in central america. important life attributes include early maturity (3-4 mo), multiple clutches of a single egg per breeding season, and low survival. population turnover is essentially annual as less than 5% adults live more than one year. my objectives were to resolve the following specific questions: 1) where are eggs laid? 2) does survival differ among different types of oviposition site? 3) how is the survival o ... | 1988 | 28312017 |
