Asynchronous Hatching

In migratory birds, arrival date and hatching date are two key phenological markers that have responded to global warming. A body of knowledge exists relating these traits to evolutionary pressures. In this study, we formalize this knowledge into general mathematical assumptions, and use them in an ecoevolutionary model. In contrast to previous models, this study novelty accounts for both traits—arrival date and hatching date—and the interdependence between them, revealing when one, the other or both will respond to climate. For all models sharing the assumptions, the following phenological responses will occur. First, if the nestling-prey peak is late enough, hatching is synchronous with, and arrival date evolves independently of, prey phenology. Second, when resource availability constrains the length of the pre-laying period, hatching is adaptively asynchronous with prey phenology. Predictions for both traits compare well with empirical observations. In response to advancing prey phenology, arrival date may advance, remain unchanged, or even become delayed; the latter occurring when egg-laying resources are only available relatively late in the season. The model shows that asynchronous hatching and unresponsive arrival date are not sufficient evidence that phenological adaptation is constrained. The work provides a framework for exploring microevolution of interdependent phenological traits.

The need for cover is a requirement in all parts of the world. More or less this need has been realized in almost every society. In addition, clothing is one of the basic needs of human beings. This basic need has become a pleasure over time, and the temporary innovation that has entered the life of society with the desire to dress completely or the need for change has turned into an excessive, common indulgence shown by the society for a certain period of time. When we evaluate clothing in terms of nations, it has gained very different meanings with the effect of the cultural structure of the society. Considering this situation in the context of civilizations, of course, we can say that it has presented a similar privilege. In short, every society has made its dress code suitable for its culture and civilization. As in the rest of the world, the robes, dresses, turbans and fabrics of the Ottoman sultans showed themselves clearly as an indicator of the position, wealth and status. Especially caftans, fabrics and patterns, each one is a masterpiece of art. Despite having a simple form according to researches, Ottoman caftans have a very magnificent appearance and beauty. The decorations made for these caftans, lining and moldings, fur ornaments, ornaments made with buttons are very perfect. These caftans have aroused the admiration of the whole world with their fabric, motif and splendor, and many researches have been done on these caftans, which have been exhibited and preserved in various local and foreign museums. The sultan's clothes in the Topkapı Palace Museum Sultan's Clothes Archive consist of approximately 2500 pieces. Most of these are hilat, robes and shalwars. In addition, although it is less, there are also children's (prince's) clothes, so there are no women's clothes.

Abiotic conditions and demographic factors can influence the timing of spawning. Behavioral plasticity allows females to select spawning conditions that are conducive to offspring development; however, reproductive costs associated with delaying spawning are not well understood. In this study, factors influencing timing of female spawning, residence time (RT), and reproductive success (RS) during two seasons were determined, and plasma testosterone concentrations were used to quantify atretic rates in a wild, lake sturgeon (Acipenser fulvescens) population. For the 123 females monitored, RT ranged from 1 to 23 days and was influenced by arrival date, temperature, discharge, and male number, with the latter having the largest influence. RS varied due to arrival date, temperature, discharge, male number, male length, and operational sex ratio. Two females had testosterone levels indicative of atresia and RS estimates lower than yearly means; however, most females had normal ovaries, suggesting little reproductive costs of plasticity in spawning ground residency time. Results demonstrate the multitude of factors influencing female reproductive behavior and RS, highlighting the importance of abiotic and demographic conditions to recruitment in wild populations.
