Humans have exhaustively combusted fossil fuels, and released pollutants into the environment, at continuously faster rates resulting in global average temperature increase seawater pH decrease. Climate change is forecasted to exacerbate effects of such as emergent rare earth elements. Therefore, objective this study was assess combined rising (Δ = + 4 °C) decreasing - 0.4 units) on bioaccumulation elimination gadolinium (Gd) bioindicator bivalve species Spisula solida (Surf clam).

Information on the early ontogeny of Lipophrys pholis is scattered and incomplete. In this paper we describe for first time full developmental sequence from egg to juvenile in controlled conditions. addition, some notes spawning behaviour adults larvae are provided. During oviposition, female follows male´s path, suggesting that male may apply sperm nest before spawning. Embryonic development lasted 16 days (17ºC) larval settlement 29 (15.5-17.5ºC). At hatching, mean total length was 5.0 mm....
Abstract Thyroid tissue in teleosts is located mainly the pharyngeal region, usually reaching other adjacent anatomical locations. Herein, a nodular lesion left operculum of Senegal seabream ( Diplodus bellottii ) was surgically excised and sent for microscopical evaluation. Microscopically, presented irregular borders consisted columnar epithelial cells arranged tubulopapillary pattern, surrounding central lumen filled with acellular, acidophilic homogeneous, material (‘colloid’). To...
The full developmental sequence from egg to juvenile of Gobius paganellus under controlled conditions is described. Embryonic development lasted 9–10 days at 18.5–20.0°C and 10–11 15.0–16.5°C. Newly hatched larvae measured 3.90 mm, had the mouth anus opened, pigmented eyes almost no yolk. They first settled 25 after hatching (10.0–10.5 mm total length [TL]) showed behaviour body form 36 (14.0 TL). However, they only pigmentation patterns 15 later (17.0 TL) (16.0–16.5°C). In addition, a...
Salaria fluviatilis is one of the few freshwater members family Blenniidae and occurs around Mediterranean Basin. This species vulnerable or endangered in most countries where it occurs. Thus, information on its developmental biology establishment methods for ex situ reproduction highly populations, to preserve them until natural habitats are restored, much needed. A technique culture this controlled conditions presented, together with description full sequence, from egg adult. The use...
Ex situ breeding programs are important conservation tools for endangered freshwater fish. However, developing husbandry techniques that decrease the likelihood of disease, antimicrobial resistance, and virulence determinants acquisition during this process is challenging. In pilot study, we conducted a captivity experiment with Portuguese nase (Iberochondrostoma lusitanicum), critically leuciscid species, to investigate influence simple protective measures (i.e., material disinfection...
Anthropogenic increased atmospheric CO2 concentrations will lead to a drop of 0.4 units seawater pH and ocean warming up 4.8°C by 2100. Contaminant's toxicity is known increase under climate change scenario. Rare earth elements (REE) are emerging contaminants, that until now have no regulation regarding maximum concentration discharge into the environment become vital new technologies such as electric hybrid-electric vehicle batteries, wind turbine generators low-energy lighting. Studies...
Ex situ reproduction of species in risk extinction has been recognized by several authors (e.g., Gipps 1991; Maitland and Lyle 1992; Xia et al. 2005; Gayton 2008) as a solution for populations whose survival is threatened an extremely low number individuals severe habitat degradation. Under such scenarios, although it may be difficult to preserve the original genetic diversity species, ex seems only avoid complete extirpation or population, preserving their last representatives until...
The full developmental embryonic sequence of Gobius cruentatus is described for the first time. Embryonic development lasted 13 days (14·0–15·0°C). newly hatched larvae (3·3 mm total length) presented pigmented eyes, yolk fully absorbed, and mouth anus were opened allowing onset exogenous feeding almost after hatching.
The full developmental sequence from egg to juvenile of Lipophrys trigloides in controlled conditions is described. In addition, some notes on the spawning behaviour adults are provided. Embryonic development lasted 13–14 days at 21·00–23·00°C, 16–17 17·25–18·50°C and 17–18 14·00–16·50°C. Newly hatched larvae measured 4·8 mm, had mouth anus opened, pigmented eyes almost no yolk. Most settled between day 39 42 after hatching 16·0–17·0 mm total length (TL) showed pigmentation patterns 5 10...

Embryonic development lasted 9 days at 18.0 21.0°C, 14 17.0 20.0°C, 16 16.0 19.0°C and 17 14.0 18.5°C. Newly hatched larvae measured 3.1 mm total length (TL), had the mouth anus open, pigmented eyes, almost no yolk, pectoral fins were small unpigmented. Most settled between day 66 69 after hatching (27.0 TL) showed pigmentation patterns 91 93 (30.0 TL). However, on 61/62...
Parablennius gattorugine and ruber are closely related sympatric western European species. In this note, traits that distinguish the larvae of both species presented it is demonstrated conflicting descriptions reported in literature on P. stem from confusion between two
Abstract During the spring of 2022, several endangered leuciscid species ( Anaecypris hispanica , Squalius aradensis Anachondrostoma Occidentale and Iberochondrostoma lusitanicum ) were sampled both at Vasco da Gama aquarium facilities in some rivers Algarve region, Portugal. Sperm samples extracted by gentle abdominal pressure sperm motion parameters assessed for first time four species, using a computerized analysis system. The results obtained showed that spermatozoa kinetic patterns...
The diverse physiography of the Portuguese land and marine territory, spanning from continental Europe to Atlantic archipelagos, has made it an important repository biodiversity throughout Pleistocene glacial cycles, leading a remarkable diversity species ecosystems. This rich is under threat anthropogenic drivers, such as climate change, invasive species, use changes, overexploitation or pathogen (re)emergence. inventory, characterization study at inter- intra-specific levels using genomics...

Introduction: Besides the knowledge of life cycles in nature, sustained use aquatic biological resources also requires development know-how to reproduce and maintain them captivity [Citation1]. The scyphozoan Catostylus tagi, native Tagus Sado estuaries, has already shown applicability areas gastronomy drugs for humans potential be used as food aquaculture organisms [Citation2]. In this work we started investigate benthic stages C. tagi their maintenance laboratory.Materials methods:...
