Reproductive Mode of Corbicula tobae (Martens, 1900): Brooding and Larval Morphology in Lake Toba (Indonesia)

open access: yesDiversity, 2022
Currently, the reproductive mode of the Indonesian endemic species Corbicula tobae from Lake Toba is yet to be investigated. In this study, we describe, for the first time, the reproductive mode of this endemic species based on a series of topotype ...

Foraging mode affects extinction risk of snakes and lizards, but in different ways

open access: yesConservation Letters, 2023
What factors render a species more vulnerable to extinction? In reptiles, foraging mode is a fundamental ecological dimension: some species actively search for immobile prey, whereas others ambush mobile prey. Foraging mode is linked to diet, morphology,

Reproductive output in spiny lizards (genus Sceloporus) with different reproductive mode. A comparative approach

open access: yesRevista Mexicana de Biodiversidad, 2020
The analysis of the reproductive output variation within a lineage is fundamental to understand life-history evolution. When different reproductive modes occur within the same lineage, the comparison of the reproductive output of each mode becomes ...

A Perspective on the Importance of Reproductive Mode in Astrobiology

open access: yesAstrobiology, 2003
Reproduction is a vital characteristic of life, and sex is the most common reproductive mode in the eukaryotic world. Sex and reproduction are not necessarily linked mechanisms: Sexuality without reproduction exists, while several forms of asexual reproduction are known.

Egg retention and intrauterine embryonic development in Sceloporus aeneus (Reptilia: Phrynosomatidae): implications for the evolution of viviparity

open access: yesRevista Mexicana de Biodiversidad, 2012
Egg retention (ER) and intrauterine embryonic development (IED) have been considered intermediate steps in the evolution from oviparity to viviparity. Sceloporus aeneus is an oviparous lizard that is closely related to the viviparous species (Sceloporus ...

Evolution of reproductive modes in sharks and rays

open access: yesJournal of Evolutionary Biology, 2023
Abstract The ecological and life history drivers of the diversification of reproductive modes in early vertebrates are not fully understood. Sharks, rays and chimaeras (group Chondrichthyes) have an unusually diverse variety of reproductive modes and are thus an ideal group to test the factors driving the evolution of reproductive ...

An unusual reproductive mode in Hypsiboas (Anura: Hylidae)

open access: yesZoologia (Curitiba), 2011
We report an unusual reproductive behavior of Hypsiboas pardalis (Spix, 1824). Species belonging to this genus usually are known to reproduce in lentic water bodies, with the development of exotrophic tadpoles.

How does the mode of evolutionary divergence affect reproductive isolation?

open access: yesPeer Community Journal, 2023
When divergent populations interbreed, the outcome will be affected by the genomic and phenotypic differences that they have accumulated. In this way, the mode of evolutionary divergence between populations may have predictable consequences for the ...

Interspecific hybrids between Paspalum plicatulum and P. oteroi: a key tool for forage breeding

open access: yesScientia Agricola, 2016
Grama-tio-pedro (Paspalum oteroi Swallen) is a rare stoloniferous grass of the Plicatula group of Paspalum, well adapted to continuous grazing in areas subject to seasonal flooding in the Pantanal region, in central western Brazil.
