Diversity of sponges (Porifera) from cryptic habitats on the Belize barrier reef near Carrie Bow Cay.
TLDR
It is determined that about 75 of the 122 cryptic sponge species studied (61%) are exclusive members of the sciophilic community, 47 (39 %) occur in both, light-exposed and shaded or dark habitats.
Growth and age of the southernmost distributed gecko of the world (Homonota darwini) studied by skeletochronology
TLDR
The model indicates that sexual maturity in H. darwini is reached at five years in females and nine in males, which corresponds to a k-selected trait of late maturity and long life expectancy, and supports the hypothesis that daytime burrow temperatures, which are similar to body temperatures recorded in diurnal Lizard species, meet the physiological growth requirements of nocturnal lizard species.
Adaptation of reef and mangrove sponges to stress: evidence for ecological speciation exemplified by Chondrilla caribensis new species (Demospongiae, Chondrosida)
TLDR
Sponges in mangroves have adapted to a wide range of environmental parameters except for extended periods of exposure to freshwater or air, and there is evidence that sponges flourishing in both mangrove and reef habitats may develop separate ecologically specialized and reproductively isolated populations.
Age and growth of the Patagonian lizard Phymaturus patagonicus
TLDR
It is postulate that severe environments such as the north Patagonian steppe play a significant role in the selection of not only modes of reproduction but also delayed maturity and prolonged reproductive cycles, a combination that results in low fecundity.
Sexual System, Sex Ratio, and Group Living in the Shrimp Thor amboinensis (De Man): Relevance to Resource-Monopolization and Sex-Allocation Theories
TLDR
The sexual system of the symbiotic shrimp Thor amboinensis is described, along with observations on sex ratio and host-use pattern of different populations, to support predictions central to theories of resource monopolization and sex allocation.
Lissodendoryx: rediscovered type and new tropical western Atlantic species (Porifera: Demospongiae: Poecilosclerida: Coelosphaeridae)
TLDR
It is found that L. isodictyalis, subgenus Lissodendoryx, is a Caribbean sponge characterized by smooth megascleres, ectosomal tylotes and choanosomal styles, and one size-class of microscleres comprising arcuate isochelae and sigmas.
Dietary analysis of Homonota darwini (Squamata: Gekkoni- dae) in Northern Patagonia
TLDR
The constraint of nocturnality, coupled with low night-time temperatures restricting feeding to only a few hours after sunset, appear to have caused a generality of diet which may limit energy acquisition.
Vulnerability to climate warming of four genera of New World iguanians based on their thermal ecology
Climate change and rising global temperatures pose a serious threat to biodiversity. We assessed the vulnerability to global warming of four genera of iguanian lizards whose distributions include a
Links between thermoregulation and aging in endotherms and ectotherms
TLDR
The aim in this review is to present, discuss, and scrutinize the thermoregulatory mechanisms that are implicated in the aging process in endotherms and ectotherms, and demonstrates that low body temperature benefits lifespan in both endothermic and ectthermic organisms.
Thermal effects on locomotion in the nocturnal gecko Homonota darwini (Gekkonidae)
TLDR
It is concluded that, although the low temperatures of Patagonia impose heavy constraints on the physiological performance of Homonota darwini, they have a peculiar arrangement of mechanical and biochemical abilities which allows for resource acquisition at night, using cryptic habits and short sprint runs.
