Land mammals of the Caribbean Islands biodiversity hotspot have suffered a high rate of extinction since human arrival, principally in the last years since colonialism began. Here, we present an extensive review and bibliography of this topic in Cuba, including details regarding the surviving endemic species Destruccion de habitat yahoo dating volant and terrestrial mammals and locations of species on protected areas.
We analyzed patterns of species richness, endemism, body mass, diet, habitat, geographic distribution of the observed richness, conservation threats, and possible causes and threats to future extinction. Cuban mammal biodiversity is comprised of 59 native species, 24 extinct species and 35 extant species, most of which are endemic to the Cuban archipelago. We compared the threats of habitat destruction Destruccion de habitat yahoo dating hunting, with emphasis on invasive mammal species Destruccion de habitat yahoo dating drivers of historical extinction in Cuba.
A total of 44 mammal species have been introduced sincewith 33 invasive species living in the wild and exerting differing degrees of impact, principally by predation and competition. Additionally, Destruccion de habitat yahoo dating evaluated interactions among invasive and native mammals, emphasizing predation of feral cats upon Solenodon cubanusCapromys piloridesand other small endemic vertebrates as determined from analyses of scat contents. The Caribbean Islands are classified as a hotspot of world biodiversity with a high concentration of endemic and threatened genera and families Myers et al.
This geographic area has experienced one of the globally highest rates of extinction in the last years, with Caribbean mammals representing The Cuban archipelago is an important part of the Caribbean Islands hotspot, hosting significant biodiversity and endemism, including the greatest number of vertebrate and mammal species in the region. As with other Caribbean islands, "Destruccion de habitat yahoo dating" species richness in Cuba is not as extensive as in adjacent mainland areas, especially for terrestrial mammals, but is instead proportionately richer in endemic species.
Several recent analyses have been published on the conservation of Cuban mammals, including summaries of existing legislation, protected areas, conservation status, and human threats Mancina et al.
These studies concluded that invasive species, habitat deterioration, and hunting are the leading factors threatening the persistence of endemic Cuban mammals. In particular, invasive species are considered the most immediate threat for Caribbean biodiversity today Wege et al. In this review, we will reevaluate species-level biodiversity, conservation status, and threats for Cuban terrestrial mammals, including bats.
We especially investigate the impacts of invasive species on the native mammal fauna and the role of invasions upon historical and recent extinctions. Cuba is an archipelago Fig. The Cuban archipelago presently is forested over Destruccion de habitat yahoo dating coastline is roughly 6, km in length and has mangrove forests covering around 4, km 2. All of these biomes are suitable habitats for various species of native Cuban mammals.
Maps Destruccion de habitat yahoo dating the Cuban archipelago showing: A digital elevation model with geographical regions and relevant localities for Cuban mammals, B the annual mean precipitation gradient Hijmans et al.
In this study, we analyzed in detail 2 localities. This protected area is drier with an annual rainfall of around 1, mm, and is home to a native population of C. We generated distribution maps for extinct and extant native mammals using records obtained from the literature, museum databases, personal communications, and from our own field survey data collected across Cuba over a year period.
Point occurrences were compiled into a database of 3, records of all species of extinct and extant native Cuban mammals occurring in 1, localities, all of which were georeferenced. Geographic information system software ArcGIS We mapped the number of unique species that occurred in each cell considering 4 major groupings: Data classes were based on natural groups, i.
We then calculated the percentage of occurrences for each extant species that lies
Destruccion de habitat yahoo dating protected areas. Separate maps were generated for extant and extinct species. We conducted an "Destruccion de habitat yahoo dating" bibliographic review of native and invasive Cuban mammals, and updated this information with our unpublished data and experience.
We reviewed management plans of Cuban protected areas, many of them updated for native mammals in the new System Plan of Protected Areas — CNAPand we reviewed 86 management plans with data on invasive mammals.
The management plans of protected areas with legal administration are available as unpublished manuscripts from the National Center for Protected Areas CNAP, Spanish acronym. Using these data, each species was classified according to the extent of their geographic distribution in quartiles of the following classes: Although our mapping effort in some instances misrepresented poorly surveyed localities, it provided the best resolution available from current data.
Based on the degree of specialization for types of roosts and habitats, we assigned volant and terrestrial mammals to the following classes: Diet was used to classify them as frugivore, folivore, nectarivore, insectivore, piscivore, or hematophage. Within this general framework, we aimed to evaluate past extinction processes, the causal role of invasive species, and the present vulnerability of surviving native species to extinction.
Endemic Cuban mammals, their conservation status, and threats are considered, including conservation categories for mammals in the Cuban Vertebrates Red Book Table 1 ; Mancina We also summarized interactions among invasive mammals, including a list of species sharing distributions in protected areas, offshore islands, Destruccion de habitat yahoo dating other habitats with endemic Cuban mammals, and the influence of human activity and economic development on the native fauna.
Endemic mammals species and subspecies in Cuba and their conservation status and threats. Invasive mammals listed in bold font have high impacts predation and competition ; invasive mammals listed in regular font have lesser impact on endemic mammals. Invasive mammals sharing Destruccion de habitat yahoo dating, but without recognized impacts Destruccion de habitat yahoo dating endemic mammals are not included.
We evaluated the cumulative increase in each of the introduced vertebrate species in Cuba species, from unpublished data and discuss key mammal introduction events. We recorded all human-caused introduction events accidental or intentionalexcluding mammals brought to Cuba for zoo exhibitions if they have never lived in wild conditions. For each invasive species, we provided their introduction date, source of introduction, pathways, number of protected areas invaded, and offshore islands where information on levels of interaction and impacts "Destruccion de habitat yahoo dating" available.
The level of interaction among introduced and native mammals was considered as high, medium, low, and none relative to their degree of overlap in distribution, habitats, and refuges; evidence of predation and competition; number of protected areas that are invaded; and links to possible extinction in past and recent times. The level of impact was evaluated following Hawkins et al.
We followed Duncan et al. This definition explicitly excludes any connotation of impact to define a species as invasive and is based exclusively on ecological and biogeographical criteria: Additionally, we used trapping data to study the density of black rats in the habitat of Cuban Solenodon. Also, we examined scats of feral cats to infer their diet in the same Solenodon habitats and in an offshore island habitat.
We performed a rapid assessment of black rat Destruccion de habitat yahoo dating at the El Toldo site with live traps baited with either toasted coconut or bread with pig fat and used the removal method of Wilson et al. We set 10—16 Sherman traps at each of 3 plots near water sources for 7—11 days. Each plot contained 2 trap lines separated by 5 m with traps set every Destruccion de habitat yahoo dating m, and each plot covered an area of —1, m 2. Traps were pre-baited for 2 days prior to being activated to enhance trap success, and were examined 2 times during the night.
All animals were removed, after transferring into a black bag and killed by cervical dislocation using procedures listed in Sikes et al. We examined 83 scats collected from feral cats, which consisted of 43 scats collected in March from S. Scats were collected to broadly survey the diet of feral cats at El Toldo by walking a line transect for 4 h over 13 successive days around our camping place, and at Cayo Campo using a transect of m on an open trail and with dusty places appropriate for the hiding of scats by cats.
For most bat species, we follow the systematic arrangement of Simmons except for Natalidae Tejedor The taxonomic status of Antrozous koopmani Orr and Silva Taboada,remains unclear; it is here retained as an endemic species and distinct from A.
Although several authors have treated Phyllonycteris poeyi as a polytypic species common to Cuba and Hispaniola e. Simmons considered Eumops ferox as a synonym of E. The Cuban subspecies of the common vampire bat Desmodus rotundus was raised to specific rank D. However, based on newly available specimens, Orihuela found that Cuban specimens fell within the range of variation observed in D. For the taxonomy of terrestrial mammals capromyids and soricomorphswe follow the last reviewers Woods and Kilpatrick ; Silva Taboada et al.
We reject the result of Leite and Patton and Fabre et al. Cuban terrestrial mammals include 59 species of fossil or extant mammals, including 38 endemic species The 24 fossil Cuban mammals are represented by 5 orders: Soricomorpha 2 speciesPilosa 5Rodentia 7Primates 2and Chiroptera 8and all fossil species are endemic to Cuba, except 2 fossil bats and 1 soricomorph also found on Hispaniola.
The 35 extant species of terrestrial Cuban mammals are represented by 8 rodents, 1 soricomorph, and 26 bats. Of the extant mammals, 17 are endemic to Cuba Extant and extinct bats have the highest richness among the Cuban mammals with 34 "Destruccion de habitat yahoo dating" of which 14 are endemics Seventeen of the living species of Cuban mammals have geographic ranges that are either widespread 9 or wide 89 have moderate distributions, and 9 are range-restricted micro-endemics.
The 11 threatened species have restricted 8moderate 2or wide 1 distributions; 6 of the 8 restricted species are limited to only 1 locality Table 1. All range-restricted species are considered threatened by the Cuban Vertebrates Red Book. According to the Cuban Vertebrates Red Book, 10 species are considered threatened including 6 as Critically Endangered, 1 as Endangered, and 3 as Vulnerable excluding
Destruccion de habitat yahoo dating garridoiwhich is not categorized in the Cuban Red Book because of its uncertain taxonomic status; Table 2.
Many invasive mammals, including those with highly invasive impacts globally, are co-distributed with endemic mammal species and in many instances share the same refuges or burrows. Rapid estimates of density for black rats Rattus rattus in Solenodon habitat in Alejandro de Humboldt National Park March by removal trapping.
Many extant and extinct Cuban mammals have or have had a folivorous diet, including all capromyid and echimyid
Destruccion de habitat yahoo dating, megalonichid sloths, and primates. Insectivory is present in 22 bats and 3 soricomorphs. Ten species are phytophagous bats, 1 is piscivorous, and the extirpated Desmodus rotundus puntajudensis feeds on blood.
A large proportion of Cuban mammals use the canopy of primary and secondary forest trees as foraging habitat and refuges. Fourteen living and extinct species excluding bats are tree- or ground-dwelling. Mesocapromys angelcabrerai and some populations of C.
Mysateles prehensilis is a strictly arboreal species. However, various habitats are or were used by Cuban mammals at one time: Highest-diversity areas coincide with areas of mountainous terrain, wetlands, and the coastal
Destruccion de habitat yahoo dating. Archipelagos contain key distributions of extant mammal species, thus are central to the conservation goals of the SNAP.
However, distribution records appear to be biased by collection effort and road infrastructure i. The highest and middle levels of species richness are concentrated in mountain systems Fig.
The plotted terrestrial mammal distributions show Fig. The map of bat species richness illustrates many areas without records of However, several grid cells harbor 13—18 species Fig. The eastern part of Cuba has the highest concentration of endangered Cuban mammals coexisting with populations of Solenodon and M. Distribution patterns of the observed richness of extant Cuban mammals: A all 35 native species; B 9 terrestrial species; C 26 bat species; and D 11 endangered species.
For fossil species Fig. We found that the diversification of the studied lineages dates to the Middle Miocene to Due to the accelerated destruction of their natural habitat, steps should be taken to ensure the E-mail: [email protected] A market stall in Sri Lanka displays the country's rich banana diversity.

Dismount mammals of the Caribbean Islands biodiversity hotspot have suffered a high rate of extinction since human arrival, principally in the last years since colonialism began. Here, we present an considerable review and bibliography of that topic in Cuba, including details regarding the surviving endemic species of volant and terrestrial mammals and locations of species on protected areas.
We analyzed patterns of species richness, endemism, portion mass, diet, habitat, geographic parcelling of the observed richness, upkeep threats, and possible causes and threats to future extinction.
Cuban mammal biodiversity is comprised of 59 native species, 24 archaic species and 35 extant species, most of which are endemic to the Cuban archipelago. We compared the threats of bailiwick destruction and hunting, with force on invasive mammal species as drivers of historical extinction in Cuba.
A total of 44 mammal species have been introduced since , with 33 invasive species living in the exciting and exerting differing degrees of impact, principally by predation and competition.
Additionally, we evaluated interactions among invasive and native mammals, emphasizing predation of feral cats upon Solenodon cubanus , Capromys pilorides , and other petty endemic vertebrates as determined from analyses of scat contents.
