Slow life histories in lizards living in the highlands of the Andes Mountains
(Springer Heidelberg, 2017-11-17)
In the highlands of the Andes, lizards must balance precisely the allocation of energy for growth and reproduction to ensure their survival. We studied the individuals’ age, growth rates, age at sexual maturity, and maximum ...
Indirect measures of reproductive effort in a resource-defense polygynous ungulate: Territorial defense by male guanacos
(Springer Tokyo, 2012-01)
Trade-offs between reproductive effort and activities that are likely to enhance survival have been studied extensively in harem defense ungulates. However, among resource defense systems, ecological determinants of the ...
Comparative reproductive effort and fecundity in the spider crabs, leurocyclus tuberculosus and libinia spinosa (Majoidea, Brachyura)
(Zoological Society of Japan, 2014-04)
A comparative analysis of reproductive effort, fecundity, and egg weight was conducted in two species of spider crabs, Leurocyclus tuberculosus and Libinia spinosa, during one-year period. Ovigerous females were collected ...
Biosynthesis in the Albumen Gland-Capsule Gland Complex Limits Reproductive Effort in the Invasive Apple Snail Pomacea canaliculata
(Marine Biological Laboratory, 2018-08)
High fecundity often contributes to successful invasives. In molluscs, this may be facilitated by the albumen gland-capsule gland complex, which in gastropods secretes the egg perivitelline fluid that nourishes and protects ...
Breeding biology of Magellanic Penguins (Spheniscus magellanicus) at the Beagle Channel: interannual variation and its relationship with foraging behaviour
(Wiley Blackwell Publishing, Inc, 2016-07)
Interannual variation in seabird foraging or reproductive behaviour may reflect fluctuations in marine resources. In this study, we evaluated different foraging and breeding parameters of Magellanic Penguins (Spheniscus ...
Coupling Epidemiological Models with Social Dynamics
(Springer, 2021-07)
In this work we study a Susceptible-Infected-Susceptible model coupled with a continuous opinion dynamics model. We assume that each individual can take measures to reduce the probability of contagion, and the level of ...
Population and reproductive patterns of the Neotropical planarian Girardia capacivasa (Platyhelminthes, Tricladida), and the influence of seasonality on its life history
(Elsevier Gmbh, 2018-05)
The biology of Neotropical freshwater planarians (Platyhelminthes) is almost unknown compared with that of their Holarctic relatives. In this paper, we 1) studied the sequence of development of the reproductive system of ...
Spermatogenic and Testosterone Cycles in a Desert-Adapted Amphibian Odontophrynus barrioi from the Monte Desert, Argentina
(Society for the Study of Amphibians and Reptiles, 2018-03)
Few studies have characterized the reproductive cycles of desert anurans, particularly species from South America. This has hampered efforts to identify broad patterns in anuran reproduction, which are known to vary both ...
MASTREE+: Time-series of plant reproductive effort from six continents
(Wiley, 2022-04-01)
Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over many years and such ...
New insights into reproductive physiology in Antarctic fish: a trial in Lepidonotothen nudifrons
(Springer, 2021-06)
The spatio-temporal delimitation of fish reproduction is essential for the appropriate management and conservation strategies in populations. Assessing this feature in Antarctic Ichthyology is particularly difficult because ...
