LEK BEHAVIOR of THE PLOVERCREST (STEPHANOXIS LALANDI, TROCHILIDAE)
(Wilson Ornithological Soc, 2012-03-01)
I examined the lek structure and behavior of male Plovercrests (Stephanoxis lalandi) at a lek in southern Brazil. The lek included seven territorial males; the distance between neighboring lek territories was 14.8 +/- 6.3 ...

Microsatellite markers for Bokermannohyla species (Anura, Hylidae) from the Brazilian Cerrado and Atlantic Forest domains
(Brill Academic Publishers, 2014-01-01)
We characterized 22 polymorphic microsatellite markers for the Brazilian treefrog Bokermannohyla ibitiguara and tested their cross-amplification in B. alvarengai, B. circumdata and B. hylax. Our focal species occurs in ...
Patterns of asymmetry in body traits and genitalia in two distant populations of a Neotropical scorpion
(Taylor & Francis, 2014-01)
The ability of a genotype to control the stable development of a phenotype under different environmental conditions may explain the level of developmental instability. An indicator to developmental instability is Fluctuating ...
Plasticity in insect olfaction: to smell or not to smell?
(Annual Reviews, 2016-03)
In insects, olfaction plays a crucial role in many behavioral contexts, such as locating food, sexual partners, and oviposition sites. To successfully perform such behaviors, insects must respond to chemical stimuli at the ...

EVALUACIÓN DE LA DIVERSIDAD GENÉTICA DE LA TORTUGA LORA (Lepidochelys kempii) EN TAMAULIPAS
(2011-12-12)
Kemp's ridley (Lepidochelys kempii) is the smallest of seven species of sea
turtles and the only one that nests during the day massively in Mexico. The ridley
population declined during the decade of the 80's from 160,000 ...
Display activity and foraging costs of a frugivorous lekking bird
(2018-12-01)
Sexual success of males in lek breeding systems is often determined by display activities that require high energetic costs and may represent honest signals of male quality to females. In this context, manakins (Aves, ...
Perspectives on invasive amphibians in Brazil
(Public Library Science, 2017-09-22)
Introduced species have the potential to become invasive and jeopardize entire ecosystems. The success of species establishing viable populations outside their original extent depends primarily on favorable climatic ...
Human impacts on pollination, reproduction and breeding systems in tropical dry forest plants
(Island Press, 2011)
Over the last two decades several studies have shown that plant species of contrasting life-forms ranging from small herbs to large trees may experi-ence a decline in reproductive success following habitat fragmentation ...
