Crustacean zooplankton species richness in Chilean lakes and ponds (23 degrees-51 degrees S)
(UNIV CATOLICA DE VALPARAISO, 2013)
Patterns of endemism in south-eastern Pacific benthic polychaetes of the Chilean coast
(BLACKWELL, 2006-04)
Aim In this study we evaluate patterns of endemism for benthic polychaete species along the southeastern Pacific coast of Chile. Our goals were (1) to describe latitudinal gradients of endemism and identify areas of high ...
Tadpole community structure in lentic and lotic habitats: richness and diversity in the Atlantic Rainforest lowland
(British Herpetol Soc, 2017-07-01)
The analysis of species richness and community composition provides basic information to understand the structure of species assemblages. Here, we compared species richness and composition, compositional similarity and ...

Variability of esterase patterns in adult flies of the saltans species group of Drosophila (subgenus Sophophora)
(Springer, 2009-09-01)
Esterases are known for their involvement in several physiological processes and high degree of polymorphism, in many organisms. Such polymorphism has been used to characterize species and species groups and to study genetic ...

Rareness and specialization in plant-pollinator networks
(Ecological Society of America, 2011-01)
Most rare species appear to be specialists in plant-pollinator networks. This observation could result either from real ecological processes or from sampling artifacts. Several methods have been proposed to overcome these ...
Reproductive compatibility and chromosome pairing in the Drosophila buzzatii complex
(Faculty Press, 1997-01-01)
Fertility (percentage of fertile crosses) and the degree of synapsis in salivary gland chromosomes in isofemale lines of Drosophila buzzatii, D. serido, D. koepferae and D. seriema were analysed. D. buzzatii was completely ...
