Chihuahua is Mexico’s largest state, and its physiographic complexity affects the distribution of its herpetofauna. We list amphibians and reptiles for the state of Chihuahua, with their conservation ...status. We also compare this list to those of six adjoining states in the United States and Mexico (New Mexico, Texas, Coahuila, Durango, Sinaloa, and
Sonora
). A total of 175 species of amphibians and reptiles is found in Chihuahua. Thirty-eight are amphibians, and 137 reptiles. Chihuahuan amphibians and reptiles represent just over 37% of such species from Chihuahua and neighboring states. Chihuahua shares the highest proportion of its herpetofauna with
Sonora
and Durango. Most of the herpetofauna of Chihuahua falls in IUCNs least concern category and is not listed by
SEMARNAT
. However, turtles in Chihuahua are a group of particular conservation concern.
A comprehensive and updated summary of the literature and unpublished records contained in scientific collections on the helminth parasites of the elasmobranchs from Mexico is herein presented for ...the first time. At present, the helminth fauna associated with
Elasmobranchii
recorded in Mexico is composed of 132 (110 named species and 22 not assigned to species), which belong to 70 genera included in 27 families (plus 4
incertae sedis
families of cestodes). These data represent 7.2% of the worldwide species richness.
Platyhelminthes
is the most widely represented, with 128 taxa: 94 of cestodes, 22 of monogeneans and 12 of trematodes;
Nematoda
and
Annelida
:
Hirudinea
are represented by only 2 taxa each. These records come from 54 localities, pertaining to 15 states; Baja California Sur (17 sampled localities) and Baja California (10), are the states with the highest species richness: 72 and 54 species, respectively. Up to now, 48 elasmobranch species have been recorded as hosts of helminths in Mexico; so, approximately 82% of sharks and 67% of rays distributed in Mexican waters lack helminthological studies. The present list provides the host, distribution (with geographical coordinates), site of infection, accession number in scientific collections, and references for the parasites. A host-parasite list is also provided.
The first checklist of the Peruvian
Hymenoptera
listed 1169 species and subspecies of aculeate wasps, including 173 species of
Pompilidae
, seven of
Scoliidae
, 39 of
Sphecidae
and 403 of
Vespidae
. ...Herein are reported 32 species as new for Peru based mainly on the collection of the Natural History Museum, London. The loss of the endemic status of two species is also reported:
Entypus
peruvianus
(Rohwer) (
Pompilidae
:
Pepsinae
) and
Omicron
ruficolle
schunkei
Giordani Soika (
Vespidae
:
Eumeninae
).
Paraguay, a country whose economy is based mainly on agriculture and livestock for export, has experienced a major expansion in mechanized crops during the last few decades. Despite being heavily ...dependent on agriculture, Paraguay has very limited research on crop weeds, in spite of these having a high economic impact on production. This work aims to update and enhance the knowledgebase on the most common weeds affecting productive fields throughout the different ecoregions of Paraguay. We present here the first checklist of crop weeds for the country, which includes a total of 256 taxa (189 species, 10 subspecies, 54 varieties and 3 forms), with the most species-rich families being
Poaceae
and
Asteraceae
followed by
Malvaceae
,
Amaranthaceae
,
Fabaceae
and
Solanaceae
. The list includes three new records for the country. Synonyms, distribution details within Paraguay, habit and a voucher specimen are provided for each taxon.
The present checklist includes data on the species composition, geographic distribution and feeding preferences of thrips species in Bulgaria. In total, 155 species in 48 genera are listed. Of these, ...125 species belong to suborder
Terebrantia
and include 103 species of 33 genera in family
Thripidae
, 14 species of two genera in
Aeolothripidae
, seven species of two genera in
Melanthripidae
and one species in
Fauriellidae
. In suborder
Tubulifera
, 30 species of 10 genera in the single family
Phlaeothripidae
are listed. Of the 155 Bulgarian thrips species, 87.7% are phytophagous, 4.5% are obligate predators, 5.8% are mycophagous and 1.9% are with unknown feeding preferences. Fourteen pest species are listed for Bulgaria, of which
Frankliniella
occidentalis
,
Thrips
tabaci
and
Haplothrips
tritici
are of economic importance. The list provides detailed information on the horizontal and vertical distribution of
Thysanoptera
in 5 regions and 45 subregions of Bulgaria. The present paper also includes an evaluation of the biodiversity of
Thysanoptera
and the extent to which each region of the country has been studied.
Understanding the abundance and richness of species is one of the most fundamental steps in effecting their conservation. Despite global recognition of the significance of the below-ground component ...of diversity for ecosystem functioning, the soil remains a poorly studied terrestrial ecosystem. In South Africa, knowledge is increasing for a variety of soil faunal groups, but many still remain poorly understood. We have started to address this gap in the knowledge of South African soil biodiversity by focusing on the
Collembola
in an integrated project that encompasses systematics, barcoding and ecological assessments. Here we provide an updated list of the
Collembola
species from South Africa. A total of 124 species from 61 genera and 17 families has been recorded, of which 75 are considered endemic, 24 widespread, and 25 introduced. This total number of species excludes the 36 species we consider to be dubious. From the published data,
Collembola
species richness is high compared to other African countries, but low compared to European countries. This is largely a consequence of poor sampling in the African region, as our discovery of many new species in South Africa demonstrates. Our analyses also show that much ongoing work will be required before a reasonably comprehensive and spatially explicit picture of South Africa’s springtail fauna can be provided, which may well exceed 1000 species. Such work will be necessary to help South Africa meet its commitments to biodiversity conservation, especially in the context of the 2020 Aichi targets of the Convention on Biological Diversity.
The bryophytes of Capitán Prat province have remained one of the least explored in Chile. The eventual construction of several dams on the rivers Baker and Pascua required prospection of all groups ...of organisms including bryophytes, work that was facilitated by the recent construction of vehicular roads that now offer easy access to previously almost unaccessible locations. The results of intense bryophyte collecting during the austral summer of 2007 are here presented. A total of 260 moss taxa are reported for the province, corresponding to 256 species and four infraspecific taxa, of which 211 are new records for the province, 54 are new for Aisén Region, and two are new records for continental Chile (
Pohlia
longicollis
(Hedw.) Lindb. and
Rigodium
toxarion
var.
robustum
(Broth.) Zomlefer). Twelve species extend their known distribution ranges to the north, whereas 49 extend them to the south.
We provide an updated checklist and key to the 30
Poa
species with open panicles from Peru which includes previously circumscribed
Dissanthelium
and
Aphanelytrum
species, new taxon records, and three ...undescribed species.
Poa
compressa
,
Poa
grisebachii
, and
Poa
leioclada
are recorded from Peru for the first time. A number of species are placed in synonymy:
Poa
carazensis
,
Poa
ferreyrae
and
Poa
tovarii
are synonymized under the name
Poa
fibrifera
;
Poa
adusta
(tentatively) and
Poa
pilgeri
are synonymized under
Poa
candamoana
;
Poa
superata
is synonymized under
Poa
grisebachii
; and
Poa
paramoensis
is synonymized under
Poa
huancavelicae
. Included within this treatment are three new species,
Poa
ramoniana
,
Poa
tayacajaensis
and
Poa
urubambensis
, which are described and illustrated.
Poa
ramoniana
, found growing near lakes in high elevation Puna grasslands of Junín, is similar to a small form of
Poa
glaberrima
, but differs in having rhizomes and growing to only 5 cm tall.
Poa
tayacajaensis
, found from shrublands on Andean slopes of Huancavelica and Huánuco, bears similarities to
Poa
aequatoriensis
but differs in having shorter lemmas which are pubescent between the veins, densely scabrous sheaths with smooth, glabrous throats, and shorter ligules.
Poa
urubambensis
, a common element of the undisturbed
Polylepis
forest understory of the Cordillera
Urubamba, Cusco, is distinct from all other members of open-panicled
Poa
’s by having glabrous lemmas with a smooth and glabrous callus, and notably small anthers. The type material for the name
Poa
adusta
is discussed and a lectotype is selected.
