“…Our results suggest that northern harriers are now occupying areas dominated by sagebrush less than in the 1990s but have increased their use of agriculture areas around the edge of the NCA. Unlike areas high in cheatgrass cover and fragmented sagebrush, some agricultural areas with more edge habitat may contain higher densities of small mammals than surrounding areas (Renwick and Lambin , Sullivan et al ), and may therefore attract foraging harriers. Although rough‐legged hawks also occupied sagebrush habitat less in the 2010s than in the 1990s, they also used agricultural areas less than in the 1990 s. In contrast to harriers, rough‐legged hawks are now positively associated with invasive plant‐dominated communities.…”

Changing habitat use associated with distributional shifts of wintering raptors

et al. 2015

There is widespread evidence that multiple drivers of global change, such as habitat degradation, invasive species, and climate change, are influencing wildlife. Understanding how these drivers interact with and affect species may be difficult because outcomes depend on the magnitude and duration of environmental change and the life history of the organism. In addition, various environmental drivers may be evaluated and managed at different spatial scales. We used a historical dataset from 1991 to 1994 and current information from 2010 to 2012 to examine whether occupancy patterns of wintering raptors were consistent with regional changes in distribution or habitat conditions within a local management unit, the Morley Nelson Snake River Birds of Prey National Conservation Area (NCA). We predicted that if local populations reflected regional shifts, then rates of raptor occupancy within the NCA would be higher compared to historical estimates and birds would use different habitats compared to historical use. Alternatively, if local populations were determined by habitat conditions, then we predicted that occupancy rate of raptors within the NCA would be lower compared to historical estimates and current habitat use would be consistent with historical use. Results support the hypothesis that northward distributional shifts influenced wintering raptor populations in southwest Idaho to a greater extent than local habitat conditions. Wintering raptors had higher occupancy rates in 2010-2012 compared to 1991-1994, whereas invasive grasses have increased and native shrubs have decreased suggesting that habitat suitability for raptors has declined over time. On the species level, changes in habitat use were associated with greater increases in occupancy rates in

“…This is unfortunate given their merit as study systems in relation to environmental and conservation issues (e.g. Rodríguez-Estival and Smits 2016; Pardini et al 2005;Jumeau et al 2017;Sullivan et al 2012). Considering the ecological signi cance of small mammals, it is important to understand their diversity and their interactions in ecosystems.…”

Within the Mesoamerican biodiversity hotspot, Costa Rica shows high species richness, due to its biogeographical, tectonic and climatic history. Small mammals (i.e. species of less than 500 grams) are a very diverse group in Costa Rica with about 52 native species. This high diversity, recent records of new species and molecular studies detecting cryptic genetic diversity highlight this group and this region as an important target for the DNA barcoding approach. Here we used 131 tissue samples across multiple localities in Costa Rica and sequenced the complete mitochondrial cytochrome b (1140 bp). These samples represented 17 recognized species (including Didelphis marsupialis, which is technically not a small mammal) and two taxa of uncertain status. The new sequence data were supplemented with previously published data from INSDC. Our phylogenetic analyses are consistent with and extend upon recent revisions in Heteromys, Peromyscus and Reithrodontomys and suggest possible new cryptic forms within what are currently named Melanomys chrysomelas, Nyctomys sumichrasti and Proechimys semispinosus. The previously named “Heteromys sp” is indeed likely a new species requiring a full taxonomic description. Our results suggest the continuity of previously described species at our newly described localities in Costa Rica reinforcing recent taxonomic surveys and field guides for the small mammals of Costa Rica. To confirm the presence of cryptic species and major genetic forms in Heteromys, Peromyscus, Reithrodontomys, Melanomys, Nyctomys and Proechimys there needs to be greater sampling, additional genetic markers, morphometrics and other studies. Scotinomys also shows interesting phylogenetic subdivision, requiring further investigation.

“…These two sectors combined are involved in the management of 72% of the land in the EU, therefore playing a major role in the status of Europe's biodiversity (EC ). Semi‐natural habitats in agricultural landscapes (e.g., grass strips, single trees, hedgerows, and forest patches) support the vast majority of the species diversity in agro‐ecosystems (Butet & Leroux, ; Dover & Sparks, ; Sullivan, Sullivan, & Thistlewood, ). However, agricultural landscapes have drastically changed in many countries as farms intensified their activities and became highly mechanized, at the expense of semi‐natural habitats (Baudry, Bunce, & Burel, ).…”

“…Among the semi‐natural habitats in agricultural areas, hedgerows, and small forest patches provide relatively permanent habitats within a constantly disturbed environment, acting as suitable habitats for many plant and animal species (Decocq et al., ; Roy & de Blois, ; Van Den Berge et al., ). They provide shelter, breeding sites, habitats, and food resources for a range of invertebrates (Burel, ; Dover & Sparks, ; Duelli, Studer, Marchland, & Jakob, ), birds (Clergeau & Burel, ; Dmowski & Koziakiewicz, ; Hinsley & Bellamy, ), small mammals (Butet & Leroux, ; Gelling, Macdonald, & Mathews, ; Sullivan et al., ; Tattersall, Avundo, Manley, Hart, & Macdonald, ), and several carnivore species (Červinka, Šálek, Padyšáková, & Šmilauer, ; Dondina, Kataoka, Orioli, & Bani, ; Šálek, Kreisinger, Sedláček, & Albrecht, ). Here, we focus on the diversity and composition of the plant community, because of its importance for the functioning of these ecosystems, including its relationship with many trophic levels (Siemann, Tilman, Haarstad, & Ritchie, ; Steffan‐Dewenter & Tscharntke, ).…”

Questions: How did hedgerows and forests change in area between 1974 and 2015 and did hedgerows still show the same vegetation composition in 2015? To what degree did the vegetation change in hedgerows and how do these changes compare to changes in forests? What is the nature of the species that changed and, from these, can we make general inferences about possible drivers of change? Location: The countryside in the municipality of Turnhout, province of Antwerp, northern Belgium. Methods: Through a resurvey of 54 and 20 quasi-permanent plots in hedgerows and forests, respectively, we investigated shifts in the herb layer over the period 1974-2015. The plot-level mean Ellenberg Indicator Values (EIVs) were calculated and soil samples were taken in 2015. We compared diversity statistics and used used Generalized Linear Mixed-Effects Models (GLMMs) to detect trends in species richness (SR) and EIVs. Via a non-metric multidimensional scaling (NMDS) ordination based on the Sørensen dissimilarity, we compared shifts at the community level.Results: Our study shows severe, but opposite changes in SR in forests and hedgerows. In forests, SR declined and a homogenization occurred. The shifts in EIVs indicate that forest vegetation evolved to more shade-tolerant and nutrient-demanding species, likely due to eutrophication combined with natural forest succession. In hedgerows, SR significantly increased. The species pool became more diverse and more heterogeneous. Changes in EIVs suggest a change towards more lightdemanding species, possibly caused by fragmentation of the network, and towards species indicative for nutrient-rich habitats, benefiting from eutrophication. Conclusions:In general, SR in hedgerows is higher than in forests in our studied region, being a suitable habitat for a wide range of plant species in the countryside.However, the loss of almost 30% of the hedgerow habitat in 41 years confronts us with the challenge of protecting the hedgerow remnants, in the interest of agro-biodiversity.
