Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

[Inbreeding process and establishment of new inbred lines derived from the Japanese house mouse, Mus musculus molossinus].

open access: yesJikken dobutsu. Experimental animals, 1993
Inbreeding of 8 groups in molossinus mouse began in (Miura female x Urawa male) F1 (MU) from the stock captured in the Kanto district of Japan and were accomplished by each primiparous littermates. The animals were kept under a clean conventional condition at 23.5 +/- 2.5 degrees C and 50 +/- 5% in relative humidity.

Spawning behaviour between endemic delta smelt (Hypomesus transpacificus) and non‐native Wakasagi (H. nipponensis) in the San Francisco estuary

open access: yesJournal of Fish Biology, EarlyView.
Abstract In the San Francisco Estuary, non‐native Wakasagi Hypomesus nipponensis hybridize with endemic and endangered Delta Smelt H. transpacificus, and all wild‐caught hybrids have a maternal Wakasagi parent. However, the mechanisms that facilitate or impede hybridization and explain sex‐biased hybrid asymmetry between these two species remain ...

Morphofunctional effects of captivity on the microanatomy of the talus bone in a wild ungulate (Sus scrofa)

open access: yesJournal of Anatomy, EarlyView.
Our study explores the plastic changes induced by captivity on the microanatomy of the talus of wild boars, revealing denser bone with tighter trabecular networks but a lower relative maximum thickness of compact bone. These plastic adaptations can serve to detect early processes of domestication in the archaeological record.

Dioecy in a wind-pollinated herb explained by disruptive selection on sex allocation via inbreeding avoidance

open access: yes
The evolution of dioecy from hermaphroditism is widely thought to be a response to disruptive selection favoring males and females, driven by advantages of inbreeding avoidance, sexual specialization, or both.

The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Genomic analyses of giant kelp reveal restricted connectivity across the Southern Hemisphere and striking diversity in Aotearoa (New Zealand)

open access: yesJournal of Phycology, EarlyView.
Abstract The macroalga Macrocystis pyrifera (“giant” or “bladder” kelp) plays a vital role in cold‐temperate marine ecosystems but faces increasing threats from ongoing environmental change. Understanding its population diversity and connectivity is essential for predicting future range shifts and assessing the ecological consequences of such shifts in

Identifying thermally tolerant bull kelp (Nereocystis luetkeana) source populations for restoration under climate change

open access: yesJournal of Phycology, EarlyView.
Abstract Kelp forests are declining in many parts of the world due to climate change and other stressors. Restoration is one solution to return kelp forests to places where they have been lost, yet continually warming oceans may necessitate the identification of thermally tolerant strains to facilitate the long‐term success of kelp restoration.
