Effects of temperature and time constraints on the seasonal variation in nest morphology of the Thorn tailed Rayadito (Aphrastura spinicauda)
(Taylor & Francis, 2017)
Environmental adjustment is the most invoked explanation for intra-seasonal variation in bird nest morphology. However, time constraints may also be important, coming as a trade-off between the costs of nest building and ...
Influência da sazonalidade e do sexo na hematologia, na citoquímica e na bioquímica do estresse oxidativo e metabólico de Chelonoidis carbonarius (Spix, 1824), mantidos em cativeiro
(Universidade Estadual Paulista (Unesp), 2020-07-02)
As variações sazonais nos fatores bióticos e abióticos influenciam no metabolismo de répteis, principalmente por serem animais ectotérmicos. Assim, os organismos dependem de ajustes comportamentais, morfológicos, fisiológicos ...
Cardiac hypertrophy and structural and metabolic remodeling related to seasonal dormancy in the first annual cycle in tegu lizards
(Elsevier B.V., 2013-07-01)
Morpho-functional adjustments in the heart of juvenile tegu lizards (Tupinambis merianae) were analyzed at distinct seasonal periods to investigate how the demands of growth and of energy saving are reconciled during the ...
Trend, seasonal, and sectorial inflation in the Euro Area
(Banco Central de Chile, 2020)
A central focus of monetary policy is the underlying rate of inflation
that might be expected to prevail over a horizon of one or two years.
Because inflation is estimated from noisy data, the estimation of
this underlying ...
Leptin levels, seasonality and thermal acclimation in the Microbiotherid marsupial Dromiciops gliroides: Does photoperiod play a role?
(Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2019)
Seasonal metabolic changes in a year-round reproductively active subtropical tree-frog (Hypsiboas prasinus)
(ELSEVIER SCIENCE INC, 2009)
Although seasonal metabolic variation in ectothermic tetrapods has been investigated primarily in the context of species showing some level of metabolic depression during winter, but several species of anurans maintain ...
What factors can influence the reproductive phenology of neotropical piper species (Piperaceae) in a semi-deciduous seasonal forest?
(2018-01-01)
Plant phenophases can be modulated by abiotic factors as well as by evolutionary history. We tested the influence of factors shaping the reproductive phenology of 17 co-occurring Piper species in a semi-deciduous seasonal ...
