Abstract Various aspects of population structure and dynamics of Eleutherodactylus coqui in two forest reserves (Maricao and Guilarte) of the central mountain range of Puerto Rico were determined between July 1997 and June 1998. Adult density ranged from 8–25 animals/100 m2 for the wet season and 3–19 animals/100 m2 for the dry season. Abundance of froglets and juveniles was also greater in the wet season compared to the dry season. By contrast, egg mass counts were greater in the dry season… 

Population Ecology of the Riparian Frog Eleutherodactylus cuneatus in Cuba

A population of the poorly known riparian frog Eleutherodactylus cuneatus was studied for 1 yr along a mountain stream in eastern Cuba. We examined population structure, seasonal and daily activity,

Modeling the Impact of Batrachochytrium Dendrobatidis in the Life History Dynamics of Eleutherodactylus Coqui Under Seasonality

Eleutherodactylus Coqui a native amphibian in Puerto Rico and invasive specie in Hawaii, can be infected by an endemic disease called Batrachochytrium dendrobatidis. Puerto Rico and Hawaii have two

Population Structure and Reproductive Pattern of Pristimantis Aff. Fenestratus (Anura: Strabomantidae) in Two Non-Flooded Forests of Central Amazonia, Brazil

According to data collected on gravid female occurrence, juvenile number variation, and presence of calling males, it is suggested that P. fenestratus reproduces during the rainy season showing marked seasonality.

Population Density Estimates and Growth Rates of Eleutherodactylus coqui in Hawaii

This work used mark-recapture methods to estimate E. coqui survival and abundance, determine growth rates of adult male and female frogs, and relate densities to elevation, snout–vent length, habitat structure, and invertebrate abundance.

Eleutherodactylus coqui Thomas(Caribbean tree frog)

The coqui experienced a severe bottleneck when it was introduced, and all measures of genetic diversity are much higher in Puerto Rico than Hawaii (Peacock et al, 2009), so Hawaii is the focus of this chapter.

Potential consequences of the coqui frog invasion in Hawaii

The Puerto Rican frog, Eleutherodactylus coqui, has invaded Hawaii and has negatively impacted the state's multimillion dollar floriculture, nursery and tourist industries; however, little is known

Population structure and activity pattern of one species of Adenoma Steindachner, 1867 (Anura: Leptodactylidae) in northeastern Brazil

We analyzed the population structure and sexual size dimorphism of an Adenomera species occurring in the municipality of Sao Goncalo do Amarante, from September 2010 to August 2011, using pitfall

Reproductive ecology of the glass frog Espadarana prosoblepon (Anura: Centrolenidae) in an urban forest of the Central Andes of Colombia

The reproductive behaviour of E. prosoblepon did not vary widely between a population in Costa Rica and their population in time to oviposition, and mating success of males associated to chorus tenure; however, in the study population the authors recorded a larger clutch size and the preference for S. geniculata fronds as Oviposition substrate.

Reproductive ecology of the Puerto Rican frog Eleutherodactylus coqui

The results suggest that female coquies should be strongly selected to exercise mate choice based on variables that correlate with hatching rate, i.e., male parental care quality and nest site quality.

Arboreal habitat use and parachuting by a subtropical forest frog

Tree frogs in the Luquillo Experimental Forest of Puerto Rico use most of the vertical spectrum of its habitat at some time during life, and by foraging in the canopy as well as at lower levels frogs may broaden their food niche to include canopy invertebrates and predation by frogs may influence populations of canopy arthropods.

Climate Driven Population Fluctuations in Rain Forest Frogs

Over the period 1979 to 1989, the number of frogs observed was negatively correlated with the longest dry period during the previous year, and extended dry periods may be lethal to adults who are inhibited from feeding because of potential desiccation.

The impact of Hurricane Hugo on forest frogs in Puerto Rico

By October 1990 adult population density had increased fourfold over prehurricane levels, although adults were smaller, and juvenile numbers also appeared to be increasing, but had not yet reached prehurricanes densities.

Population Density of Tropical Forest Frogs: Relation to Retreat Sites

The hypothesis that shortages of nest and retreat sites limit population size was tested by placing 100 bamboo frog houses in plots measuring 100 square meters in areas of high frog density, and new sites were readily adopted by adult frogs.

SEXUAL DIMORPHISM IN ELEUTHERODACTYLUS COQUI: SELECTION PRESSURES AND GROWTH RATES

It is suggested that size dimorphism in this species is maintained by energetic constraints, resulting from male reproductive behavior, that reduce growth.

The unusual amplectic posture probably functions to increase the efficiency of sperm transfer and may be a behavioral correlate of internal fertilization in this species.
