DOI: 10.1002/ece3.3128
Abstract: Abstract All species should invest in systems that enhance longevity; however, a fundamental adult life‐history trade‐off exists between the metabolic resources allocated to maintenance and those allocated to reproduction. Long‐lived species will invest more in… read more here.

DOI: 10.1002/ece3.9770
Abstract: Abstract Animal behavior is motivated by the fundamental need to feed and reproduce, and these behaviors can be inferred from spatiotemporal variations in biological signals such as vocalizations. Yet, linking foraging and reproductive effort to… read more here.

Reproductive effort in the domesticated red alga Agarophyton chilense: differences between farms and natural populations
Sign Up to like & getrecommendations! Published in 2021 at "Journal of Applied Phycology"
DOI: 10.1007/s10811-020-02325-8
Abstract: Macroalgal domestication and farming can induce significant ecological and biological changes in exploited species. In the red macroalga, Agarophyton chilense, marine farming is based on clonal propagation by cuttings of the largest plants. This type… read more here.

DOI: 10.1016/j.yhbeh.2016.07.004
Abstract: The purpose of this paper is to review field studies of human male hormones and reproductive behavior. We first discuss life history theory and related conceptual considerations. As illustrations, distinctive features of human male life… read more here.

Fitness consequences of peak reproductive effort in a resource pulse system

DOI: 10.1038/s41598-017-09724-x
Abstract: The age trajectory of reproductive performance of many iteroparous species features an early - life increase in performance followed by a late - life senescent decline. The largest contribution of lifetime reproductive success is therefore… read more here.

Reproductive effort and oxidative stress: effects of offspring sex and number on the physiological state of a long‐lived bird
Sign Up to like & getrecommendations! Published in 2017 at "Functional Ecology"
DOI: 10.1111/1365-2435.12829
Abstract: Summary 1.Individuals must trade-off between energetically costly activities to maximise their fitness. However, the underlying physiological mechanism remains elusive. Oxidative stress, the imbalance between reactive oxygen species production and antioxidant and/or repair activities, has been… read more here.

Climatically controlled reproduction drives interannual growth variability in a temperate tree species

DOI: 10.1111/ele.13158
Abstract: Abstract Climatically controlled allocation to reproduction is a key mechanism by which climate influences tree growth and may explain lagged correlations between climate and growth. We used continent‐wide datasets of tree‐ring chronologies and annual reproductive… read more here.

DOI: 10.1590/0001-3765202220210179
Abstract: Reproductive biology is fundamental to understanding the ecology and evolution of lizards which, in turn, is essential for the definition of the species´ conservation status. We studied life-history traits related to the reproduction of the… read more here.
