Background:Habitat loss and fragmentation in the Sierra Madre Oriental(SMO)ecological corridor have negative impacts on the movement and distribution of mammalian species that are of great ecological and evolutionary importance.Part of the SMO ecological corridor that is located in the state of Hidalgo is less studied despite being a potential dispersal route for mammals.The objectives of this study were to evaluate the presence and activity of terrestrial mammals in the riparian and non‑riparian zones of SMO.Results:Camera traps detected 15 mammalian species(i.e.,14 native and 1 domestic)in the non‑riparian zone,and 12 mammalian species in the riparian zone(i.e.,10 wild and 2 domestic).The riparian corridor was mainly used by opportunistic medium‑sized carnivores,while large carnivores and their potential prey were more frequent in the non‑riparian zone.Conclusions:Our findings suggest terrestrial mammals avoid the use of natural corridors due to the presence of domestic dogs,cattle and humans and look for new dispersal routes to move through their habitat and find the resources they need to survive.Even though some species can use disturbed corridors to move and find resources,they will change their activity patterns to avoid contact with humans and potential threats like dogs.It is,therefore,crucial to identify not one,but several corridors that must be preserved to improve the connectivity of terrestrial mammals in disturbed landscapes.

Following a large-scale phylogenetic study of the lichenized genus Cora(Basidiomycota:Agaricales:Hygrophoraceae),we formally describe 70 new species,honouring the seventieth birthday of David Leslie Hawksworth,one of the preeminent figures in mycology and lichenology in the past 50 years.Based on an updated phylogeny using the ITS fungal barcoding locus,we now recognize 189 taxa in a genus that until recently was considered to represent a single species;including this contribution,92 of these are formally recognized,including five taxa based on historical names or collections that have not been sequenced.Species of Cora can be recognized by a combination of morphological(size,colour,lobe configuration,surface hairs,hymenophore size and shape),anatomical(thallus thickness,cortex structure,photobiont type,hyphal papillae),and ecogeographical features(substrate,habitat,distribution),and a keytable allowing the identification of all accepted taxa is provided.The new species are:Cora accipiter Moncada,Madrin˜a´n&Lücking spec.nov.,C.applanata Moncada,Soto-Medina&Lücking spec.nov.,C.arachnodavidea Moncada,Dal Forno&Lücking spec.nov.,C.arborescens Dal Forno,Chaves&Lücking spec.nov.,C.arcabucana Moncada,C.Rodrı´guez&Lücking spec.nov.,C.aturucoa Lücking,Moncada&C.Vargas spec.nov.,C.auriculeslia Moncada,ya´nez-Ayabaca&Lücking spec.nov.,C.barbifera Moncada,Patin˜o&Lücking spec.nov.,C.boleslia Lücking,E.Morales&Dal Forno spec.nov.,C.caliginosa Holgado,Rivas Plata&Perlmutter spec.nov.,C.campestris Dal Forno,Eliasaro&Spielmann spec.nov.,C.canari nugra,Dal Forno&Lücking spec.nov.,C.caraana Lücking,Martins&Lucheta spec.nov.,C.casasolana Moncada,R.-E.Pe´rez&Lücking spec.nov.,C.caucensis Moncada,M.Gut.&Lücking spec.nov.,C.celestinoa Moncada,CabreraAmaya&Lücking spec.nov.,C.comaltepeca Moncada,R.-E.Pe´rez&Herrera-Camp.***.nov.,C.corani Lücking,E.Morales&Dal Forno spec.nov.,C.corelleslia Moncada,A.Sua´rez-Corredor&Lücking spec.nov.,C.crispoleslia Moncada,J.Molina&Lücking spec.nov.,C.cuzcoensis Holgado,Rivas Plata&Perlmutter spec.nov
