Data from: The trade-off between clutch size and egg mass in tree swallows (Tachycineta bicolor) is modulated by female body mass

clutch size;agricultural intensification;Tachycineta bicolor;Egg mass
摘要:
e typically limited, clutch size and egg mass are expected to be constrained, and this putative trade-off between offspring number and size is at the core
Data from: Experimental manipulation of food availability leads to short-term intra-clutch adjustment in egg mass but not in yolk androgen

摘要:
maternal effects. We experimentally studied whether egg and yolk mass and yolk hormone levels respond to short-term changes in food availability during laying
Data from: Pelvis morphology suggests that early Mesozoic birds were too heavy to contact incubate their eggs
负责人:

摘要:
by the pubic symphysis. Known elongation ratios of Mesozoic bird eggs allowed us to predict egg mass and hence the load mass an egg could endure before cracking. These
Data from: Effects of increased flight on the energetics and life history of the butterfly Speyeria mormonia
负责人:
关键词:
senescence;Resource allocation;Ageing;lifespan;insect;Speyeria mormonia;Oxidative stress;reproduction
摘要:
. We measured body mass (storage), resting metabolic rate and lifespan (repair and maintenance), flight metabolic rate (flight capacity), egg
Data from: Viviparity does not affect the numbers and sizes of reptile offspring
负责人:
关键词:
eggs;hatchlings;lizards;neonates;live bearing;oviparity;Snakes
摘要:
t of the egg mass is due to components (such as water stores and the eggshell) not required for oviductal incubation. ?That repackaging enables live-born offspring
Data from: Heritable variation in maternally-derived yolk androgens, thyroid hormones and immune factors
负责人:
关键词:
yolk hormones;genetic covariation;lysozyme;thyroid;maternal effects;IgY;Parus major;heritability
摘要:
of wild origin. Egg mass, testosterone (T) and androstenedione (A4) hormone concentrations showed moderate heritability, in agreement with earlier findings
Data from: Organizing effects of adverse early-life condition on body mass, compensatory growth and reproduction: experimental studies in rock
负责人:
关键词:
early-life food condition;Columba livia;compensatory growth;Reproductive behaviour
摘要:
-natural conditions. Impoverished and restricted food (IRF) negatively affected adult body mass, pair-bonding behaviour, courtship (males) and being courted (fema
Data from: Inbreeding depression across a nutritional stress continuum
负责人:
关键词:
egg-to-adult viability;Inbreeding;population size;Dry body mass;drosophila melanogaster;Inbreeding by environment interactions;Environmental stress
摘要:
in the developmental medium. We assessed the consequences of nutritional stress by scoring egg-to-adult viability and body mass of emerged flies
Data from: Do wolf spiders' egg-sacs emit tactochemical signals perceived by mothers?
负责人:
关键词:
terrestrial arthropods;eggs and juveniles care;maternal behaviour;contact stimuli
摘要:
discriminate between egg-sacs differencing in mass (empty or not) as they do not hang an empty egg-sac but do not discriminate between egg-sacs with viable
