Interpopulation spread of a parasitic B chromosome is unlikely through males in the grasshopper Eyprepocnemis plorans
It is hypothesized that B chromosomes most likely failed invasion in both migration events because the migrating sex shows no B-drive, and that even with recurrent migration the B chromosome failed to increase in frequency. Expand
Organismal and 'gametic' capture-recapture using microsatellite genotyping confirm low abundance and reproductive autonomy of humpback whales on the wintering grounds of New Caledonia
The close agreement of the organismal and gametic recapture estimates support the as- sumption that this humpback whale wintering ground represents an autonomous population unit that is relatively closed to demographic and reproductive interchange. Expand
Petersen and removal population size estimates: combining methods to adjust and interpret results when assumptions are violated
This application describes and recommends a two-day technique that combines aspects of both capture-recapture and removal methods of population size estimation and indicates how to test: most of the assumptions of both methods and how to adjust the population estimates obtained if violations of the assumption occur.

Aspects of the population ecology of Goniosoma sp. (Arachnida Opiliones Gonyleptidae) in limestone caves in southeastern Brazil
The new species of Goniosoma found in the city of Pains, Brazil, is well distributed in the caves of the region, occurring in 55 out of 62 visited caves, and a Principal Components Analysis (PCA) revealed a sexual dimorphism in the size of the second leg and its femur. Expand
The Schnabel Method : An Ecological Approach to Productive Vocabulary Size Estimation
This study addresses the issue of how we might be able to quantify productive vocabulary size in two groups of university students learning Spanish as L2. One group has an intermediate level ofExpand
Effect of coastal dune restoration on the population of endangered Mongolian racerunner (Eremias argus) in the Republic of Korea
The endangered species Mongolian racerunner (Eremias Argus), with a limited distribution in South Korea, is found only in sand dunes near waterside and forests. Therefore, species trends in thisExpand
Survival and Density of a Dominant Fish Species Across a Gradient of Urbanization in North Carolina Tidal Creeks
Development in the southeastern US coastal plain generates the need for a better understanding of how survival and abundance of estuarine nekton respond to urbanization. Apparent survival and densityExpand
Recreational fishery as a conservation tool for endemic Dolly Varden Salvelinus malma miyabei in Lake Shikaribetsu, Japan
Recreational angling is a popular leisure activity globally and can be a threat or useful conservation tool depending on the management strategy. Miyabe charr Salvelinus malma miyabei is an endemicExpand
Population dynamics of Aegla manuinflata Bond-Buckup and Santos 2009 (Decapoda: Aeglidae), an threatened species
Ovigerous females and juveniles were registered in all seasons of the year and there is no significant different in the proportion of these animals among the seasons, indicating continuous reproduction. Expand
