Based on this observation, three factors related to Atta sexdens were characterized: (1) initial nest morphology (depth and volume); (2) queen oviposition rate; and (3) prevalence of Escovopsis (parasitic fungus) and other fungi in incipient colonies. Our observation showed a variation in chamber dimensions and volume, indicating differences in colony development rates. The oviposition rate of queens from nests of the same age showed a difference among queens. About microfungi prevalence, it was found that many are potentially deleterious. In particular, the parasite Escovopsis was present in 16.7% of the colonies. Our study shows positive correlations between queen condition and nest size/fungus garden size. These correlations collectively suggest that ecological factors such as plant availability can generate substantial variation between nests and thus shape the success of incipient colonies.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2019-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2019.1603622","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44874507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested the effect of surface area and water depth on growth and development of tadpoles of Physalaemus albonotatus and whether habitat size effects are constant over the larval period. We performed a 2 × 2 factorial design: two water depths and two surface areas. We measured tadpoles at 15 and 30 days after starting the experiment, and recorded weight and time to metamorphosis. Our results indicate that habitat size influences the morphology, growth, and development of tadpoles and that the response changes during development. At 15 days, tadpoles reared in shallow water had reduced their morphological variables and developmental stage, whereas tadpoles reared in enclosures with different surface areas showed no differences. At 30 days, tadpoles reared in enclosures with small surface areas had increased their body length, body height, and developmental stage, whereas tadpoles reared in different water depths showed no differences. Tadpoles reared in small surface areas reached metamorphosis earlier than tadpoles reared in large surface areas. The results suggest that during ontogeny the surface area and water depth had different influence in the phenotypic plasticity of tadpoles.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2018.1549887","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46733386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To both species we compared environmental features of nest sites with Random Points (RPs). Nests of L. labyrinthicus were most commonly placed next to ponds, while L. syphax nests were restricted to sites bordering seasonal small streams. Discrimination between both species was reasonable (error 17%); L. syphax nests were on harder soil and more elevated points in relation to water level and L. labyrinthicus nests were most often beside water bodies with potential predators. Compared to RPs, L. labyrinthicus nests (error 30%) were more often hidden and closer to water, and L. syphax nests (error 11%) were more often hidden, in flatter terrains, in softer soils and closer to water. Even though L. labyrinthicus and L. syphax build nests in sites differing in hydric features and soil inclination/hardness, both species select hidden points, which seems to be important to avoid predation by dipteran larvae and desiccation.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2018.1542246","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44002956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 3,306 animals were caught monthly from August 2011 to July 2013 at the Carú River, Itacoatiara, Amazonas State (Brazil). The average carapace length of males (6.87 ± 3.45 mm) and females (6.88 ± 4.78 mm) did not differ significantly (U = 0.608; p= 0.5432) for the overall study period. The sex ratio was biased toward females (M:F = 1:1.61; χ2=83.855; p< 0.0001). The reproduction was continuous, and although juveniles were present throughout the study period, the recruitment occurred primarily during the ebb (August–September) and drought (October–December) periods. Macrobrachium brasiliense presents a low number of large eggs, and egg volume increased during embryogenesis, by 21.1% from Stage I to III. The population size-frequency distribution presented no correlation with the abiotic variables, but its reproductive period seems to be related to the Amazonian flood-pulse regime.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2018.1542195","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42191078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A morphological cladistic analysis based on the previous matrix of a Theraphosinae group confirmed the inclusion of this species within Proshapalopus. The new species, Proshapalopus marimbai n. sp., can be distinguished from other species of the genus mainly by the reduced number of labial cuspules, around 40; in contrast the other species having over 100. Males can be distinguished by the thickened femur III, presence of intermediate urticating setae type I-III only, palpal bulb with a considerably long prolateral inferior keel (from ventral median depression to embolus apex) and the accessory keel pronounced distally. Females can be distinguished for lacking urticating setae type III and the non-incrassated tibia IV. This discovery constitutes the fourth species described for Proshapalopus and the first record for Colombia, expanding the geographical distribution of the genus, until now known for Brazil only. Other aspects of distribution and the phylogenetic relationship of the new species are also discussed here. http://zoobank.org/urn:lsid:zoobank.org:pub:852AF8E4-67C3-4DD9-B386-29F5C6E9A073","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2018-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2018.1493181","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42088336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Schultze, 1840, three of which are new to science. Echiniscus belloporus n. sp. has no trunk cirri and dorsal plates densely covered with pores (sculpture of the spinulosus type); it lacks a spine I and the dentate collar IV, a combination of traits so far unseen in Echiniscus. Echiniscus ornamentatus n. sp. possesses regularly distributed pores on its dorsal plates, scapular and caudal plates with contrasting faceting, and anterior portions of the paired plates distinctly darker than their posterior parts. Echiniscus tristis n. sp. is also a new member of the spinulosus group, but differs from all other species of this complex by having small pores, a trunk appendage combination C-Dd-E, and large spurs on its internal claws. Three other species: Echiniscus baius, Echiniscus dariae and Echiniscus manuelae, are recorded as new additions to the African fauna. Two last species: Echiniscus africanus and Echiniscus cirinoi, are scarcely reported elements of the Afrotropical fauna. Scanning electron microscopy microphotographs supplementing the description of E. dariae, and amendments to the outdated description of E. manuelae are also provided. http://zoobank.org/urn:lsid:zoobank.org:act:B8494205-58D5-4E54-B54E-2C40976892E1http://zoobank.org/urn:lsid:zoobank.org:act:F439D375-F44F-4C3A-997F-EDC0D0A45F88http://zoobank.org/urn:lsid:zoobank.org:act:B602FA08-3E17-4149-A1FE-22829E13DFFD","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2018-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2018.1477350","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43890445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
