Fruit size and yield efficiency of ‘gala’ apples grown in chile depend on winter temperatures and season length
(International Society for Horticultural Science, 2019)
The influences of several management practices, as pruning, girdling, chemical and manual thinning on apple fruit size and yield efficiency, are known. Basically, yield improvement is achieved by a successful management ...
Seasonal dynamics of the water relations and photochemical efficiency of Copaifera langsdorffii Desf. co-occurring in savanna and seasonal forest
(2019-02-01)
Seasonal dynamics can have important effects on vegetation structure and the physiological responses of species that co-occur in tropical savanna and seasonal forest. Few studies have revealed the physiological adjustments ...
Seasonal variation in the thermal biology of a terrestrial toad, Rhinella icterica (Bufonidae), from the Brazilian Atlantic Forest
(2018-05-01)
As ectotherms, amphibians may exhibit changes in their thermal biology associated with spatial and temporal environmental contingencies. However, our knowledge on how amphibian´s thermal biology responds to seasonal changes ...
Seasonal metabolic changes in a year-round reproductively active subtropical tree-frog (Hypsiboas prasinus)
(Elsevier B.V., 2009-02-01)
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 ...
Daily and annual cycles in thermoregulatory behaviour and cardio-respiratory physiology of black and white tegu lizards
(Springer, 2015-12-01)
This study was designed to determine the manner in which metabolism is suppressed during dormancy in black and white tegu lizards (Tupinambis merianae). To this end, heart rate (f (H)), respiration rate (f (R)), and deep ...
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 ...
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 ...
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 ...
