Polygynandry and sexual size dimorphism in the sea spider Ammothea hilgendorfi (Pycnogonida: Ammotheidae), a marine arthropod with brood-carrying males. [PDF]

open access: yes, 2008
Species that exhibit uniparental postzygotic investment by males are potentially good systems for investigating the interplay of sexual selection, parental care and mating systems.

Pelagic Larval Duration and Population Structure of a Widely Distributed Amphidromous Fish in the Indo‐Pacific Region

open access: yesEcology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Freshwater habitats in the Indo‐Pacific Islands are colonised by amphidromous fish, which undergo a marine larval phase while the rest of the life cycle takes place in the riverine habitat. These fish are mainly represented by Gobiiformes. Among these, Stenogobius genivittatus (Valenciennes, 1837) is widely distributed in the Indo‐Pacific ...

Natal philopatry, dispersal and age of first breeding in relation to size and sex of Arctic Terns (Sterna paradisaea)

open access: yesIbis, Volume 168, Issue 1, Page 79-94, January 2026.
Many seabird species are in decline and population demographic models are important for revealing the causes and developing conservation strategies. Natal and breeding dispersal are key parameters of such models but can be challenging to estimate and may vary by sex.

Feeding ecology of pipefish species inhabiting Mediterranean seagrasses

open access: yesMediterranean Marine Science, 2020
Pipefish are a vulnerable and diverse group of ichthyofauna tightly associated to seagrass meadows, key habitats in shallow marine areas. Despite of their charismatic role, main ecological features, habitat and diet of this group remain largely unknown. This study focuses on assessing pipefish habitat and feeding preferences including different hosting

Social Interaction With Females Modulates Context‐Dependent Male Guppy Mating Tactics for Female Receptivity

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We experimentally tested how social experience influences male mating behavior and preference in guppies. Males raised in mixed‐sex groups adjusted their mating tactics based on female receptivity but did not differ in overall mate preference compared to males reared in male‐only groups. Our findings highlight how social experience can modulate context‐

The evolutionary origins of Syngnathidae: pipefishes and seahorses

open access: yesJournal of Fish Biology, 2011
Despite their importance as evolutionary and ecological model systems, the phylogenetic relationships among gasterosteiforms remain poorly understood, complicating efforts to understand the evolutionary origins of the exceptional morphological and behavioural diversity of this group.

Amazonian fish migration as a social–cultural–ecological process

open access: yesPeople and Nature, Volume 7, Issue 12, Page 3297-3312, December 2025.
Abstract In this study, we highlight the rich perspectives and explanations of fish migration held by Indigenous groups across the Amazon. We present the aspects of Indigenous cosmological stories, drawing from our exploratory review of cultural ethnographies and grey literature, as well as the authors' own experiences. We ask, how do Amazonian peoples
