Compensatory development and costs of plasticity: larval responses to desiccated conspecifics. [PDF]

open access: yesPLoS ONE, 2011
Understanding constraints on phenotypic plasticity is central to explaining its evolution and the evolution of phenotypes in general, yet there is an ongoing debate on the classification and relationships among types of constraints.

Earliest ontogeny of early Cambrian acrotretoid brachiopods — first evidence for metamorphosis and its implications

open access: yesBMC Evolutionary Biology, 2018
Background Our understanding of the ontogeny of Palaeozoic brachiopods has changed significantly during the last two decades. However, the micromorphic acrotretoids have received relatively little attention, resulting in a poor knowledge of their ...

Ontogenetic development of Parablennius pilicornis (Pisces: Blenniidae) in controlled conditions

open access: yesScientia Marina, 2006
The full developmental sequence from egg to juvenile of Parablennius pilicornis in controlled conditions is described. Embryonic development lasted 9 days at 18.0 to 21.0°C, 14 days at 17.0 to 20.0°C, 16 days at 16.0 to 19.0°C and 17 days ...

EXPERIENCE OF CREATIVITY IN EARLY ONTOGENY

open access: yesCollection of Scientific Papers of Uman State Pedagogical University, 2020
«children’s creativity» and reflects the main interpretations of these terms in psychology and pedagogy. Children’s creativity should be understood as the creation of a subjectively new (meaningful) product for the child – drawings, designs, games, stories, creation of previously unknown details that characterize the created image in a new way ...

Embryonic and larval development of Lipophrys pholis (Pisces: Blenniidae)

open access: yesScientia Marina, 2002
Information on the early ontogeny of Lipophrys pholis is scattered and incomplete. In this paper we describe for the first time the full developmental sequence from egg to juvenile in controlled conditions.

Juvenile pathogen exposure affects the presence of personality in adult field crickets

open access: yesFrontiers in Ecology and Evolution, 2015
Despite the ever increasing interest in animal personalities, i.e. among-individual variation in behavior, there are still several gaps in our understanding of how experiences during ontogeny influence the expression of behavior in adulthood.

Patterns of Carpel Structure, Development, and Evolution in Monocots

open access: yesPlants, 2023
The phenomenon of heterochrony, or shifts in the relative timing of ontogenetic events, is important for understanding many aspects of plant evolution, including applied issues such as crop yield.

Early ontogeny of the lesser sandeel (Ammodytes marinus)

open access: yesDevelopmental Dynamics, 2023
AbstractBackgroundLesser sandeel (Ammodytes marinus) is widely distributed in North Sea ecosystems. Sandeel acts as a critical trophic link between zooplankton and top predators (fish, mammals, sea birds). Because they live buried in the sand, sandeel may be directly affected by the rapid expansion of anthropogenic activities linked to their habitat on

Effects of Ontogeny on δ13C of Plant- and Soil-Respired CO2 and on Respiratory Carbon Fractionation in C3 Herbaceous Species. [PDF]

open access: yesPLoS ONE, 2016
Knowledge gaps regarding potential ontogeny and plant species identity effects on carbon isotope fractionation might lead to misinterpretations of carbon isotope composition (δ13C) of respired CO2, a widely-used integrator of environmental conditions. In
