Species

Alytes dickhilleni

Common Name(s)

Betic Midwife Toad, Sapo Partero Bético

Region where program is based

Europe

Country where program is based

Spain

The authority that recommended this species for an ex situ program

Conservation Needs Assessment Workshop

Has a genetic analysis been performed on wild populations to define the target taxon, i.e., verify that single, viable Evolutionarily Significant Units (ESU's) that are managed as separate populations, are not confounded by cryptic species or polymorphisms?

Yes

Name of the institution managing the ex situ population

ZooBotànico Jerez

Year the program started

2010

Is at least some portion of the captive population maintained in range country?

Yes

Are sufficient resources available to manage the ex situ population?

No

Are adequate numbers of skilled staff available with the appropriate ex situ amphibian experience?

Yes

Is sufficient space available for the required population size?

Yes

Additional Support required

Has a Taxon Management Coordinator for the ex situ population been appointed?

Yes

Taxon Management Coordinator

Mariano Cuadrado of ZooBotànico Jerez

Has a Taxon Management Group or Recovery Team been established?

No

Has a Taxon Management Plan, Recovery Plan or Species Action Statement been written?

No

Web link to Taxon Management Plan

Have Husbandry Guidelines been written?

No

Web link to Husbandry Management Guidelines

Have any knowledge gaps in the species biology or in their interaction with potential threats been identified that could benefit from research using the ex situ population?

Yes

List of knowledge gaps

Structure of the population, reproduction biology, the effect of emerging diseases (very common in wild populations) etc.

Have founder needs been calculated using the AArk Amphibian Population Management Guidelines ?

No

Have sufficient potential founders been collected? ( AArk Amphibian Population Management Guidelines recommends a minimum of 20 pairs of found animals).

No

If sufficient founders have not been collected, is there an ongoing search for additional founders?

No

Is the ex situ population managed by nationals from the range country?

Yes

What tools are used to maximize retention of genetic diversity?

None

Has the population produced viable offspring?

No

Have the first generation captive-bred animals bred successfully?

No

Is the ex situ population housed in permanent isolation from other populations occurring outside its range?

Yes

Is work being supported to study and mitigate threats to the species in the wild, either by the institution or by a regional wildlife agency?

Yes

Have captive-bred or captive-reared animals been released into the wild?

No

If releases were undertaken, have disease screening protocols or veterinary health checks been conducted prior to releases to the wild?

Is follow-up work being carried out to monitor progress of the released animals?

Is the taxon again secure in the wild, even if it might still require some ongoing in situ management? i.e. has the need for a captive assurance population been obviated such that we can call this a successfully terminated captive rescue program?

No

Comments

The aims of Sapo Partero B_tico Project were twofold. Firstly, we kept a few larva gathered from a wild population (we were authorised by local authorities to make a first attempt with only 25 larva from a single population) to achieve metamorphosis and hence, adult reproduction. Secondly, we improved the natural population by repairing an artificial pond settled in a highly endangered population (Granada, SE Spain). This was achieved in September 2011. We were unable to achieve reproduction of metamorphosed adults (all of them died soon after metamorphosis). The restoration of the water pond was very successful with new larvae (of related species however) were found soon after at the pond.
