Abstract:
... Standard correlation approaches in dendroclimatology provide limited scope to elucidate differences between years in timing of growth initiation and cessation. In the Southern Hemisphere (SH), with relatively few long-term climate reconstructions, a clearer understanding of signals contained in ring width variation is of particular importance. In this study, we monitored growth in detail at two si ...

Abstract:
... Schizolobium parahyba is a tropical species that has expanded its distribution. However, little is known about its ecological performance beyond the tropics. Therefore, the objective of this research was to describe for this species, south of its original distribution, intra-annual variations in primary growth phenology (leaf flushing, leaf shedding, flowering and fruiting) and secondary growth (r ...

Abstract:
... In response to a lack of data describing the population parameters of Turbinidae off south-eastern Australia, but a requirement for such information to support emerging harvest strategies, the growth of Lunella torquata was assessed from mark-recapture data using maximum likelihood and Bayesian approaches. Data for 564 tagged and recaptured L. torquata (29–90 mm shell lengths; SL) from 7658 tagged ...

Abstract:
... Some gymnosperms, including Cryptomeria japonica, exhibit needle reddening caused by red xanthophyll pigment, rhodoxanthin accumulation during long-term cold acclimation. Although photoprotective role of rhodoxanthin, serves as a “sunscreen”, was proposed, the key environmental and/or physiological factors involved in rhodoxanthin accumulation remain unclear. We exposed C. japonica trees to four d ...
... We aim to extend our understanding of the seasonal formation of cellular cementum, and its functional relationships in fallow deer (Dama dama) from Mediterranean ecosystems, in order to achieve reliable cementochronology applications. We provide a specific reference for fallow deer in a specific ecosystem, as needed for forensic, paleontological and wildlife ecology research. A semi-quantitative r ...
... The article presents the results of the study of the growth dynamics of the sprouts of 52 woody plants, representing 19 genera from 5 families, of different geographical origin. In the conditions of Southern Uzbekistan, the growth of introduced species takes place in early, more favorable spring terms and is characterized by higher intensity. With the onset of the extreme period (early June), the ...

Abstract:
... Tree growth takes place at different time scales ranging from hours to days. To understand growth responses to climate, continuous high-resolution measurements of tree diameter variations are needed, which are usually obtained with automatic dendrometers. Here, we monitored stem diameter increment of Quercus faginea Lambert growing in central Portugal to determine the effect of climate on daily an ...

Abstract:
... This data set collects capture–mark–recapture data, biometric data, and stomach contents of seven populations of the Italian cave salamander (Speleomantes italicus), one of the strictly protected European plethodontid species endemic to mainland Italy. We monitored six subterranean populations inside caves, and one fully epigean population living in a forest, surveying a total area of >5200 m². Da ...

Abstract:
... Vegetation gradients, such as those between savanna and seasonally dry tropical forest (SDTF) vegetations, may experience nearly identical macroclimatic conditions but still differ because of local ecological filters selecting for distinct plant functional aspects related to water storage and use. We examined how leaf phenology, water potential, wood density, and wood saturated water content varie ...

Abstract:
... Tropical fish stocks are perceived not to exhibit seasonality in growth. For this reason the standard von Bertalanffy growth function (VBGF) has been used widely to fit the growth of tropical fish populations compared to the seasonally-oscillating VBGF (soVBGF), which is seldom used in tropical fisheries. To advocate for the use of the soVBGF in assessment of tropical fish stocks, this study compa ...

Abstract:
... We evaluated the spatiotemporal distribution of Limnoperna fortunei larvae, its abundance in relation to other zooplanktonic organisms (copepoda and cladocerans), and its macrofouling on net cages in the Chavantes Reservoir, Brazil. We also estimated its growth rate under this condition and limnological variables in the water column. Zooplankton densities were positively related to water temperatu ...

Abstract:
... A two-year growth study of 80 Pinna rudis individuals was conducted in offshore cages in the western Mediterranean Sea. A Von Bertalanffy growth model was fitted to monthly measured data of 40 individuals (Group 1), whereas length-dry weight relationship was established with the other 40 individuals (Group 2). Oceanographic data were sampled bimonthly. The individuals showed the fastest growth rep ...

Abstract:
... The patterns of soil water and mineral nitrogen (Nₘᵢₙ) distribution, stand growth, and N uptake in a triploid Populus tomentosa plantation under two-year drip irrigation and N fertigation (DIF) treatments were investigated. There was a positive relationship between stand growth and the amount of precipitation and irrigation. Precipitation and irrigation affected the content of Nₘᵢₙ in top 0−20 cm ...

Abstract:
... The study involved seven species and cultivars of ornamental apple trees including Malus × floribunda, M. halliana, M. niedzwetzkyana, M. × purpurea, M. × purpurea ‘Ola’, M. × purpurea ‘Royalty’, and M. × purpurea ‘Selkirk’. The average value of increment, average length, and duration of shoots’ growth were determined to characterize the seasonal growth of Malus shoots. The percentages of rooted c ...
... In the Kiel Fjord, western Baltic Sea, an experimental culture of Fucus vesiculosus and Fucus serratus has been established in order to develop a sustainable method for biomass production of these species. The cultivation method includes the unattached rearing of fronds in drifting baskets and their vegetative reproduction by cutting of small vegetative apices. In this study, we performed culture ...
... The in-season dynamics of potato tuber biomass (TTB) growth requires effective nitrogen (N) control. This hypothesis was tested in 2006 and 2007. The two-factorial experiment with two rates of N (60, 120 kg ha⁻¹) and sulfur (S; 0, 50 kg ha⁻¹) was carried out in the split-plot design. The third factor was the sampling of plants at 10-day intervals. The collected plant material was divided into leav ...

Abstract:
... Vascular epiphytes in temperate zones are allegedly rare due to climatic constraints, such as drought and freezing temperatures during winter. Here, we investigate how abundance and seasonal growth of epiphytic polypod ferns in Western Europe are influenced by annual rainfall and temperature. We recorded abundances and growth of epiphytic polypod ferns over two years at three sites along a rainfal ...
... Seed distributors market lucerne to farmers based on the supposed winter activity of those cultivars. This study determines the amount of between-cultivar variation, in cultivars available to farmers, in annual dry matter production and seasonality of that dry matter production when grown in dryland grazing areas of south east Australia. Forty-seven cultivars of lucerne, that spanned the range of ...
... The strategic allocation of pasture grazing area to dairy cows is essential for optimal management and increased outputs. Rising plate meters are frequently used to estimate pasture herbage mass, i.e. dry matter yield per hectare, by employing simple regression equations that relate compressed sward height to herbage mass. However, to improve the accuracy and precision of these equations, so that ...

Abstract:
... Solar-induced chlorophyll fluorescence (SIF) is closely linked to photosynthesis, and provides new opportunities for detecting global gross primary production (GPP). Instantaneous satellite SIF products are usually available only for clear-sky condition, which means that there is a temporal inconsistency in the direct link between these and continuous carbon flux records. In this study, we designe ...
