Abstract Since 1993 the Venezuelan government has implemented an intensive management program aiming to increase the population size of the endangered giant South American turtle (Podocnemis expansa). Including nest relocation and a year of captive rearing of hatchlings, the program affects the main Venezuelan P. expansa population, located in the middle Orinoco River. Although the program seems to be increasing recruitment of new individuals into the population, the effects of such nest…

A Demographic Study of the Arrau Turtle (Podocnemis expansa) in the Middle Orinoco River, Venezuela

TLDR
It is concluded that additional efforts focused on protecting juveniles and adults of the arrau turtle, such as reinforcement of illegal hunting controls, must be implemented in order to ensure the success of the conservation program.

On the future of the giant South American river turtle Podocnemis expansa

TLDR
The spatial pattern of its abundance in relation to human and natural factors using multiple regression analyses found that > 85 conservation programmes are protecting 147,000 nesting females, primarily in Brazil, which demonstrates the need for concerted global conservation action.

On the future of the giant South American river turtle Podocnemis expansa

There is a long history of exploitation of the South American river turtle Podocnemis expansa . Conservation efforts for this species started in the  s but best practices were not established,…

Nesting Site and Hatching Success of Podocnemis unifilis (Testudines: Podocnemididae) in a Floodplain Area in Lower Amazon River, Pará, Brazil

TLDR
Investigating the environmental characteristics of nesting areas selected by Podocnemis unifilis and the spatial distribution of the nests and the influence of these factors on hatching success in a floodplain area of the lower Amazon River in Brazil found that females selected the higher sites, far from the river and next to vegetation for nesting.

Transplantation of nest of amazonian turtle Podocnemis expansa (Schweigger, 1812)

TLDR
A strong relation was found between the number of eggs and the percentage of deformities of each transplanted nest, showing that the presence of deformed individuals in turtle nests is natural.

Conservation genetics of harvested river turtles, Podocnemis expansa and Podocnemis unifilis, in the Peruvian Amazon: All roads lead to Iquitos

We present a mtDNA analysis of Podocnemis expansa (n = 81) and Podocnemis unifilis (n = 228) turtles traded in Peru to evaluate the potential origin of these animals. In particular, we were…

Biology and Conservation of the Freshwater Turtles and Tortoises of Peru

Little information has been published on Peruvian chelonians. Here we have compiled the available literature pertaining to Peruvian freshwater turtles and tortoises on four topics: Human consumption…

A Plea to Redirect and Evaluate Conservation Programs for South America’s Podocnemidid River Turtles

TLDR
It is argued that programs that only focus on nest transfer and head-starting as their conservation strategies would be better served by redirecting their efforts toward the protection of subadults and adults and in conducting monitoring programs designed to evaluate the impact of their management practices.

Turtles and Tortoises Are in Trouble

Revision of Hemoproteid Genera and Description and Redescription of Two Species of Chelonian Hemoproteid Parasites

TLDR
Molecular phylogenetic analysis of new isolates from the Peruvian Amazon strongly support the separation of the non-avian parasites into a separate genus, and proposes that subgeneric classification of Haemocystidium and Simondia be applied to parasites of squamates and chelonians, respectively.

Maternal Effects on Life-History Traits in the Amazonian Giant River Turtle Podocnemis expansa

TLDR
Fitness of female P. expansa could increase by producing larger eggs because of the advantage that larger hatchlings have in survival, and there is a potential for important effects of nest depth on sex ratios produced by different sized females within the population and possibly by single females throughout their lifetime.

On clutch size and hatching success of the South American turtles Podocnemis expansa (Schweigger, 1812) and P. unifilis Troschel, 1848 (Testudines, Podocnemididae).

TLDR
The outstanding fit of the clutch size regressions leads one to consider egg volume variability, which was found to be high in both species, in contradiction with current optimal egg size theory.

Demographics of Common Snapping Turtles (Chelydra serpentina): Implications for Conservation and Management of Long-lived Organisms

TLDR
Life history traits of long-lived organisms consist of co-evolved traits that severely constrain the ability of populations to respond to chronic disturbances, and successful management and conservation programs for long- lived organisms will be those that recognize that protection of all life stages is necessary.

Delayed sexual maturity and demographics of blanding's turtles (Emydoidea blandingii): implications for conservation and management of long-lived organisms

TLDR
The results from the present study indicate that life-history traits of long-lived organisms consist of co-evolved traits that result in severe constraints on the ability of populations to respond to chronic disturbances.

Cofán Indians’ Monitoring of Freshwater Turtles in Zábalo, Ecuador

TLDR
The Cofán Indians of Aguarico and Zábalo Rivers in Ecuador in 1990 began a turtle recuperation effort by raising turtle hatchlings in small pools, which has influenced the community's perception of turtle conservation issues so that, instead of hunting the adults and eggs, they now protect them.

Reproductive parameters and nesting behavior of the Amazon turtle Podocnemis expansa (Testudinata: Pelomedusidae) in Brazil

TLDR
The Amazon River turtle Podocnemis expansa was studied during the nesting and hatching seasons at a protected site in a Biological Reserve on the Trombetas River, a tributary of the Amazon.

Interclutch and interpopulation variation in the effects of incubation conditions on sex, survival and growth of hatchling turtles (Chelydra serpentina)

TLDR
Hatchling size cannot be used as an index of hatchling quality or posthatching success, unless interclutch and interpopulation variation are taken into account, and results support the Charnov—Bull model.

An Experimental Analysis of Natural Selection on Body Size of Hatchling Turtles

TLDR
Larger hatchling Chelydra serpentine exhibited significantly greater survivorship than smaller individuals during movement from the nest site to water, suggesting that larger body size of hatchling turtles may not evolve rapidly because the strength of selection was moderate in magnitude and the heritability was relatively low.

Effects of the Embryonic Environment and of Hatchling Housing Conditions on Growth of Young Snapping Turtles (Chelydra serpentina)

TLDR
Theribution of the myzontidae to Carangidae and its role in the food web is summarized in H. R. Longmore (ed.).

The Influence of Growth Rate on Age and Body Size at Maturity in Female Snapping Turtles (Chelydra serpentina)

TLDR
The status of Pliocercus and Urotheca (Serpentes: Colubridae), with a review of included species of coral snake mimics, is reviewed.
