Post-mating parental behavior trajectories differ across four species of deer mice.

open access: yesPLoS ONE, 2022
Among species, parental behaviors vary in their magnitude, onset relative to reproduction, and sexual dimorphism. In deer mice (genus Peromyscus), while most species are promiscuous with low paternal care, monogamy and biparental care have evolved at ...

takeout gene expression is associated with temporal kin recognition

open access: yesRoyal Society Open Science, 2023
A key component of parental care is avoiding killing and eating one's own offspring. Many organisms commit infanticide but switch to parental care when their own offspring are expected, known as temporal kin recognition.

Parental investment and immune dynamics in sex-role reversed pipefishes.

open access: yesPLoS ONE, 2020
Parental care elevates reproductive success by allocating resources into the upbringing of the offspring. However, it also imposes strong costs for the care-giving parent and can foster sexual dimorphism.

Parental care and non-parental care setting

open access: yesASIAN SCIENCE, 2015
A child always needs care and affection from their parents and family members. Parental care does matter in child’s life. If children do not get adequate care, it will affect their future life and education. But in today scenario, it becomes hard for parents to work outside for their livelihood and also give full time to their children.

Unconventional Care: Offspring Abandonment and Filial Cannibalism Can Function as Forms of Parental Care

open access: yesFrontiers in Ecology and Evolution, 2019
Parental care is a key life-history trait that increases offspring fitness. When one thinks of parental care, nurturing behaviors such as guarding, provisioning, and grooming typically come to mind. However, such conventional forms of care often co-occur

Non-kin adoption in the common vampire bat [PDF]

open access: yesRoyal Society Open Science, 2021
Individual animals across many different species occasionally ‘adopt’ unrelated, orphaned offspring. Although adoption may be best explained as a by-product of adaptive traits that enhance parental care or promote the development of parental skills, one ...

A test of male infanticide as a reproductive tactic in a cichlid fish [PDF]

open access: yesRoyal Society Open Science, 2017
Infanticide and offspring cannibalism are taxonomically widespread phenomena. In some group-living species, a new dominant individual taking over a group can benefit from infanticide if doing so induces potential mates to become reproductively available ...

K hniezdnej denzite a neobvyklému hniezdnemu správaniu Certhia brachydactyla na západnom Slovensku [PDF]

open access: yesTichodroma, 2020
Breeding and breeding density was studied in the Short-toed Treecreeper (Certhia brachydactyla) in two sites (riparian forest and park habitat) in Western Slovakia in 2015–2020. The breeding density was 3–5 nests (mean 4.2, i.e.

Dynamical Adaptation of Parental Care

open access: yesBulletin of Mathematical Biology, 2009
Two models are proposed to simulate population growth of species with mature stage and immature stage in which there are parental cares for immature. It is assumed that the protection of mature to their immature reduces mortality of immature at the cost of reduction of reproduction. Dynamical adaptation of parental care is incorporated into the models,

Reduced habitat quality increases intrinsic but not ecological costs of reproduction

open access: yesEcology and Evolution, 2022
Although the costs of reproduction are predicted to vary with the quality of the breeding habitat thereby affecting population dynamics and life‐history trade‐offs, empirical evidence for this pattern remains sparse and equivocal.
