Seasonal and daily protandry in a cyprinid fish [PDF]

Scientific Reports, 2017
In polygynandrous mating systems, in which females limit reproductive success, males can increase their success by investing in courtship. Earlier arrival at the spawning ground compared to when females arrive may increase their opportunities in ...

Life-History Responses of the Fall Webworm <i>Hyphantria cunea</i> to Temperature Change: Not Following the Temperature-Size Rule. [PDF]

Ecol Evol
The life‐history traits of the fall webworm were examined at 20°C, 22°C, 24°C, 26°C, and 28°C. Larval development time was shorter in males than females at all tested temperatures. Female body weight increased at high temperatures, while male body weight decreased.

Effect of the Social Environment on Spring Migration Timing of a Songbird

Frontiers in Ecology and Evolution, 2021
The influence of the social environment on the timing of the annual cycle is poorly understood. Seasonally migratory birds are under pressure to accurately time their spring migration, and throughout the annual cycle, they may experience variability of ...

Studies on Reproductive Development and Breeding Habit of the Commercially Important Bamboo Bambusa tulda Roxb

Plants, 2021
Compared to other grasses, flowering in bamboo is quite divergent, yet complex with respect to time to flower, number of individual culms in a population that have been induced at a time (sporadic vs.

Long-term changes in arrival timing and site functionality in two passerine species during spring migration in northeastern Pennsylvania, USA

Journal of Field Ornithology, 2023
Although there is abundant evidence that migrant landbirds have modified their migratory timing in response to climate change, few studies have looked for evidence of long-term changes in site use or function, while even fewer studies have looked for ...

The explosive flowers of Marsypianthes chamaedrys (Lamiaceae) resort to self-pollination and improve reproduction

Acta Botânica Brasílica, 2022
Explosive pollination includes a rapid release of floral sexual elements that are enclosed in modified petals, and a subsequent contact with pollinators’ body.

Andromonoecy and Floral Protandry of Oenanthe aquatica (Apiaceae)

Vestnik Tomskogo gosudarstvennogo universiteta. Biologiya, 2022
The paper studies the synflorescence structure and flowering biology of the biennial monocarpic wetland plant Oenanthe aquatica. This species has a set of adaptations to prevent self-pollination, including generation of a pseudanthium, andromonoecy, intra- and interfloral protandry, and a specific sequence of flowering within its umbels.

Parthenogenesis did not consistently evolve in insular populations of Ischnura hastata (Odonata, Coenagrionidae) [PDF]

, 2017
1. The evolutionary advantages that have driven the evolution of sex are still very much debated, and a number of benefits of parthenogenesis over sexual reproduction have been proposed.
