Cranial ecomorphology of turtles and neck retraction as a possible trigger of ecological diversification. [PDF]

Evolution, 2022
Abstract Turtles have a highly modified body plan, including a rigid shell that constrains postcranial anatomy. Skull morphology and neck mobility may therefore be key to ecological specialization in turtles. However, the ecological signal of turtle skull morphologies has not been rigorously evaluated, leaving uncertainties about the roles of ...

Effects of body size on estimation of mammalian area requirements. [PDF]

Conserv Biol, 2020
Abstract Accurately quantifying species’ area requirements is a prerequisite for effective area‐based conservation. This typically involves collecting tracking data on species of interest and then conducting home‐range analyses. Problematically, autocorrelation in tracking data can result in space needs being severely underestimated.

Amonioaren ekoizpenaren alometria interes komertzialeko txirletan [PDF]

, 2017
[EN] The aim of this research was to stablish an allometric relation between ammonium excretion-rate and body-size in Ruditapes philippinarum (Japanese carpet shell) and Ruditapes decussatus (grooved carpet shell). Due to the characteristics of the biological material obtained, the allometric relation was only stablished for R.

Radiocarbon estimates of age and growth for a dominant Amazon palm species

Biotropica, Volume 55, Issue 1, Page 7-12, January 2023., 2023
We used destructive sampling to assess 14C‐calibrated age and growth of five individuals of Oenocarpus bataua Mart. (ARECACEAE) from 7.35‐21.6 m of total height. The largest individual was 59‐years old. Age decreased from the collar to the top of the aboveground stem and was positively correlated with number of leaf‐scars and height.

Plasticity and evolution shape the scaling of metabolism and excretion along a geothermal temperature gradient

Functional Ecology, Volume 36, Issue 5, Page 1303-1314, May 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physiological rates are heavily dependent on temperature and body size. Most current predictions of organisms’ response to environmental warming are based on the assumption that key physiological rates such as metabolism and excretion scale independently with body size ...

Ciclomorfose em Bosmina (Crustacea, Cladocera) no Lago Paranoá, Brasília [PDF]

, 1989
In order to verify the existence of seasonal variations in morphology of Bosmina longirostris and Bosmina hagmanni, samples were taken from Paranoá Lake (Brasília, DF) during 1983. Body length and breadth, antennule, mucro and eye diameter were measured.

Size-dependent allocation of biomass to ancillary versus flowers of the inflorescences of the epiphyte Tillandsia stricta Soland (Bromeliaceae) Influência do tamanho do corpo na alocação de biomassa em estruturas de suporte e flores da bromélia epífita Tillandsia stricta Soland. (Bromeliaceae))

Acta Botânica Brasílica, 2009
The amount of resources invested in reproduction is closely correlated to plant size. However, the increase in reproductive investment is not always proportional to the increase in vegetative growth, as the proportion of plant resources allocated to ...
