“…No obstante, ante la sospecha de que la causa pudiera estar relacionada con el agotamiento del sustrato, se ha llevado a cabo recientemente el trasplante de los individuos supervivientes a contenedores de mayores dimensiones, rellenados con la mezcla de sustratos que se utiliza en el Centro para la Investigación y Experimentación Forestal (CIEF) de la Comunidad Valenciana para la producción de jara de Cartagena (Ferrer-Gallego et al, 2015. ), a base de turba, fibra de coco, perlita y suelo del hábitat natural de la especie en la proporción estándar 2:1:1:1.…”

Esta monografía es un punto de encuentro de gran parte de las personas e instituciones que investigan y trabajan para la conservación de la jara de Cartagena que han plasmado en ella, de forma sintética y diáfana, la mayor parte de los conocimientos actuales sobre la especie y su gestión. Los trabajos que se exponen son el fruto de la investigación y del esfuerzo personal de los numerosos colaboradores que firman los distintos capítulos, representantes de las más relevantes instituciones científicas de nuestro país y de las administraciones autonómicas de la Región de Murcia y de la Comunitat Valenciana. Quiero mencionar la importancia del encuentro que tuvo lugar en la “I Jornada técnica sobre la conservación de la jara de Cartagena” organizada por la Oficina de Impulso Socioeconómico del Medio Ambiente en noviembre de 2016 ya que, de alguna forma, supuso la formalización de la colaboración entre gran parte de los investigadores y gestores que hoy participan en esta obra. La monografía divulga los avances en distintos ámbitos, todos ellos esenciales para la conservación de la biodiversidad, desde los estudios genéticos y taxonómicos hasta las traslocaciones en el campo o la conservación ex situ. Esta amplitud de campos es una muestra de la enorme complejidad a la que se enfrenta la recuperación de una especie amenazada de extinción, frente a la cual esta publicación aspira a ser un instrumento más con el que abordar el reto de su conservación. Este carácter instrumental supone a su vez un enfoque dinámico y adaptativo ya que los trabajos y experiencias presentadas abren la puerta a futuros proyectos y líneas de investigación que completarán y ampliarán estos conocimientos y, lo más importante, redundarán en la mejora del estado de y conservación de Cistus heterophyllus en la Península Ibérica. La obra tiene una sistemática coherente y bien estructurada, abordando en primer lugar los aspectos botánicos e históricos de la especie, para pasar al análisis de sus actual status jurídico y los instrumentos legales para su protección y recuperación.

“…The small number of wild specimens of the Cartagena rockrose in the Iberian Peninsula has made it necessary to carry out studies aimed at learning the ecological preferences, ecophysiological traits, reproductive viability and survival of the plant throughout its development. These data are essential to create an effective recovery plan that contains both in situ and ex situ measures to be able to reinsert the plant in its natural environment [6,7]. Several genetic relationships of the populations have been carried out which show that the three populations of the Spanish territory seem to come from different colonisations from the African continent, the population of Cartagena being the one that shows the greatest genetic uniqueness.…”

“…Several genetic relationships of the populations have been carried out which show that the three populations of the Spanish territory seem to come from different colonisations from the African continent, the population of Cartagena being the one that shows the greatest genetic uniqueness. Most of the research is focused on promoting knowledge of the genetics of the species and its application in the recovery of populations, particularly due to hybridization problems and possible genetic poverty [7][8][9][10]. There have also been some studies on germination and propagation in the nursery with different results, in which the survival rate of plants showed a wide spectrum [11][12][13].…”

Effects of Light Intensity and Water Stress on Growth, Photosynthetic Characteristics and Plant Survival of Cistus heterophyllus Desf. Subsp. carthaginensis (Pau) M. B. Crespo & Mateo

The objective of this study was to identify the physiological mechanisms used by Cistus heterophyllus Desf. Subsp. carthaginensis (Pau) M. B. Crespo & Mateo, a species in critical danger of extinction, to cope with two typical abiotic conditions. During the summer of 2021, plants were cultivated under a shade mesh that intercepted 50% of the incident solar radiation (SHADE) and in natural conditions (SUN). Three irrigation treatments were also applied: control, T1, moderate water deficit; T2, 60% of the control, severe deficit; and T3, 30% of the control. Therefore, there were six treatments (SUN-T1, SUN-T2, SUN-T3, SHADE-T1, SHADE-T2, SHADE-T3). Plants were more affected by solar radiation than by deficit irrigation. Although leaf water potential, stomatal conductance and root biomass decreased by up to 45%, 63% and 65%, respectively, as deficit irrigation increased, plants were able to develop a leaf osmotic adjustment and an improved intrinsic water-use efficiency to maintain their growth and survival rate. Shade conditions improved gas exchange, reduced leaf temperature and induced the synthesis of chlorophylls, regardless of the irrigation level imposed. This indicated that radiation was the most limiting factor in our experiment. Applying 50% of the radiation and a moderate water deficit would help to obtain a good plant development and high survival rate in future recovery and conservation programs for the species.

Aim of study: To survey and report the behavior of the weevil Pleurodirus fairmairii as a pest species on Cistus heterophyllus subsp. carthaginensis (Pau) M.B. Crespo & Mateo (Cartagena’s rockrose), in order to provide the first biological data on this species. Cartagena’s rockrose is an Iberian endemism considered as "endangered" in the Spanish Catalogue of Threatened Species. Its current distribution is limited to the Spanish provinces of Murcia, Valencia and the Balearic Islands. Area of study: The study has been conducted in Valencia province (Spain). Material and methods: Pleurodirus fairmairii was observed in the field feeding voraciously on Cartagena’s rockrose. Damages were described, and several individuals of the weevil were captured alive for preliminary observation of their feeding habits under laboratory conditions. The trials (no-choice test) consisted of offering a freshly plucked leaf from different potential host plants to the weevils introduced individually in a Petri dish. Furthermore, a male and a female were dissected for the study of genitalia, and their respective components were prepared for microscopy study and subsequently described. Main results: This paper reports for the first time the occurrence of the weevil Pleurodirus fairmairii on plants of C. heterophyllus subsp. carthaginensis and describes the important damage it causes on leaves, stem, buds, flowers and fruits. Research highlights: A short description of the adults is given, including the genitalia, that are shown and described for the first time.
